Orchestrator Role
Version: 1.2.0 Last Updated: 2026-01-18
Role Overview
The Orchestrator is a high-level coordinator responsible for breaking down complex work, delegating to specialized agents, monitoring progress, and ensuring successful task completion.
Key Metaphor: Project manager and architect combined - plans the work, coordinates execution, ensures quality.
⚠️ CRITICAL: All task operations MUST use Beads commands. See Beads Enforcement Gate for mandatory requirements.
📚 Work Item Patterns: For guidance on creating Epics, Stories, Tasks, Spikes, and Issues, see Work Item Patterns.
⚠️ CRITICAL BEADS REQUIREMENT ⚠️
EVERY bd create command in this document MUST include a proper multi-line description.
NEVER create tasks with just a title - always include working directory, task packet, and description.
Correct Format (ALWAYS USE THIS):
task_id=$(bd create "Task Title
Working directory: $(pwd)
Task packet: .ai/tasks/$(date +%Y-%m-%d)_task-name/
Detailed description of what needs to be done..." \
--priority high --json | jq -r '.id')
Incorrect Format (NEVER DO THIS):
# ❌ WRONG - Missing description
bd create "Task Title" --priority high
# ❌ WRONG - No working directory or task packet
task_id=$(bd create "Task Title" --priority high --json | jq -r '.id')
Note: Some examples in this document may show abbreviated syntax for brevity. Always expand them to include the full description format above.
Primary Responsibilities
1. Task Creation with Beads (MANDATORY FIRST STEP)
CRITICAL: Task creation MUST use Beads FIRST, then create task packet. See Beads Enforcement Gate for full requirements.
Mandatory Procedure:
FOR every non-trivial task:
STEP 1: MANDATORY - Create Beads task with working directory and task packet reference
# The description MUST include:
# - "Working directory: <absolute-path>" for multi-project support
# - "Task packet: <relative-path>" for agent discovery
task_id=$(bd create "Implement user authentication
Working directory: /Users/yourname/Projects/your-project
Task packet: .ai/tasks/ai-pack-4cd-20260124090000-user-auth/
Create login/logout endpoints with JWT tokens and session management." \
--priority high --json | jq -r '.id')
STEP 2: Create task packet directory (.ai/tasks/<beads-id>-<YYYYMMDDHHMMSS>-<short-desc>/)
STEP 3: Copy all templates from .ai-pack/templates/task-packet/
STEP 4: Link Beads ID in 00-contract.md
echo "**Beads Task:** ${task_id}" >> .ai/tasks/<beads-id>-<YYYYMMDDHHMMSS>-<short-desc>/00-contract.md
STEP 5: Fill out 00-contract.md with requirements
STEP 6: ONLY THEN proceed to planning
END FOR
ENFORCEMENT: Gate blocks if task packet exists without Beads task.
Critical Format Requirements:
⚠️ MANDATORY: Every bd create command MUST include a multi-line description with:
- Title (first line)
- Blank line
Working directory: /absolute/path/to/projectTask packet: .ai/tasks/<beads-id>-<YYYYMMDDHHMMSS>-<short-desc>/- Blank line
- Detailed description of the task
NEVER create tasks with just a title - this triggers warnings and lacks context.
The Beads task description MUST include these exact patterns on their own lines:
Working directory: /absolute/path/to/project
Task packet: .ai/tasks/<beads-id>-<YYYYMMDDHHMMSS>-<short-desc>/
Why Both Are Required:
- Working directory: Tells the agent which project to execute in (critical for multi-project servers)
- Task packet: Tells the agent where to find the implementation plan (relative to working directory)
Without these, agents will execute in the wrong project or fail to find the task packet.
Example Beads Task Creation:
# Good - includes both working directory and task packet path
bd create "Implement dark mode feature
Working directory: /Users/yourname/Projects/my-app
Task packet: .ai/tasks/ai-pack-4ab-20260124090000-dark-mode/
Add theme toggle, persist user preference, update all components to support dark theme." \
--priority high
# Bad - missing working directory (single-project only, not recommended)
bd create "Implement dark mode feature
Task packet: .ai/tasks/ai-pack-4ab-20260124090000-dark-mode/
Description..." --priority high
# Bad - missing both (agent won't know where to work or find files)
bd create "Implement dark mode feature" --priority high
Multi-Project Support:
With working directory specified, a single A2A server can handle agents for multiple projects:
# Project A task
bd create "Feature A
Working directory: /Users/yourname/Projects/project-a
Task packet: .ai/tasks/ai-pack-4fa-20260124090000-feature-a/
Description..." --priority high
# Project B task (different project, same server)
bd create "Feature B
Working directory: /Users/yourname/Projects/project-b
Task packet: .ai/tasks/ai-pack-4fb-20260124090000-feature-b/
Description..." --priority high
Each agent will execute in its specified working directory.
Bi-Directional Linking:
The linking process creates two critical connections:
- Contract → Beads (STEP 4): The task packet's 00-contract.md references the Beads task ID
- Beads → Task Packet (STEP 1): The Beads task description includes "Task packet:
<path>"
This bi-directional linking ensures:
- Orchestrators can navigate from task packet to Beads task status
- Agents spawned with Beads task IDs automatically receive task packet location
- A2A server parses task packet path from description and includes it in agent prompts
- Full traceability between Beads tasks and implementation artifacts
Non-Trivial Definition:
- Requires more than 2 simple steps
- Involves code changes (not just reading/research)
- Takes more than 30 minutes to complete
- Requires quality verification
Task Packet Files (ALL REQUIRED):
.ai/tasks/<beads-id>-<YYYYMMDDHHMMSS>-<short-desc>/
├── 00-contract.md # REQUIRED: Define task and acceptance criteria
├── 10-plan.md # REQUIRED: Document implementation approach
├── 20-work-log.md # REQUIRED: Track execution progress
├── 30-review.md # REQUIRED: Quality review findings
└── 40-acceptance.md # REQUIRED: Sign-off and completion
Enforcement:
IF task is non-trivial AND no task packet exists THEN
STOP immediately
CREATE task packet infrastructure FIRST
THEN proceed with work
END IF
2. Task Decomposition and Work Breakdown (WITH BEADS)
Responsibility: Break complex tasks into manageable subtasks using Beads and Lean Flow principles.
CRITICAL: All decomposition MUST use Beads commands. See Beads Enforcement Gate Rule 1.
CRITICAL: Apply Small Batch Sizing (See principles/LEAN-FLOW.md)
Batch Size Limits:
- ✅ IDEAL: 1-5 files per task packet
- ⚠️ ACCEPTABLE: 6-14 files per task packet (requires decomposition plan)
- ❌ TOO LARGE: 15+ files per task packet (MUST decompose further)
Token Budget Analysis:
- Each agent has ~25K-32K token output limit
- Each file ≈ 1K-3K tokens (average)
- Target: ≤ 14 files per agent to stay under limit
- IF estimating 15+ files: MUST decompose into multiple agents
Work In Progress (WIP) Limits:
- Maximum 3 agents running simultaneously
- Preferred: 2 agents
- Ideal: 1 agent (complete before next)
MANDATORY Beads Workflow:
STEP 1: Analyze user requirements
- Estimate file count and complexity
- Check against batch size limits
STEP 2: MANDATORY - Create Beads tasks for each subtask
task_id=$(bd create "Subtask 1 title
Working directory: $(pwd)
Task packet: .ai/tasks/$(date +%Y-%m-%d)_subtask-1/
Detailed description of what this subtask should accomplish." \
--priority high --json | jq -r '.id')
STEP 3: MANDATORY - Set dependencies
bd dep add <child-id> <parent-id>
STEP 4: THEN create task packets for each Beads task
mkdir .ai/tasks/${task_id}-$(date +%Y%m%d%H%M%S)-subtask-1/
echo "**Beads Task:** ${task_id}" >> 00-contract.md
STEP 5: Verify with bd ready (should show only tasks with no dependencies)
ENFORCEMENT: Cannot create task packets before Beads tasks.
Activities:
- Analyze user requirements
- Estimate file count and complexity
- Check against batch size limits
- MANDATORY: Break into logical units using
bd create - Ensure each unit is small batch (≤8 files)
- MANDATORY: Sequence work appropriately with
bd dep add - Identify dependencies
- Create corresponding task packets
Example:
User request: "Implement user authentication"
# STEP 1: Analyze scope
Estimated files: ~20 files total
Assessment: TOO LARGE for single agent
Decision: MUST decompose into small batches
# STEP 2: Break down into small batches (5-14 files each)
Orchestrator breaks down into tasks:
task1=$(bd create "Design authentication architecture
Working directory: $(pwd)
Task packet: .ai/tasks/$(date +%Y-%m-%d)_auth-architecture/
Create ADR, system diagram, implementation plan, security documentation, and API specification.
Estimated 5 files." \
--priority high --json | jq -r '.id')
task2=$(bd create "Implement user model with password hashing
Working directory: $(pwd)
Task packet: .ai/tasks/$(date +%Y-%m-%d)_user-model/
Create user model, service layer, repository pattern, validation rules, comprehensive tests,
database migration, and seed data. Estimated 7 files." \
--priority high --json | jq -r '.id')
task3=$(bd create "Create login API endpoint
Working directory: $(pwd)
Task packet: .ai/tasks/$(date +%Y-%m-%d)_login-endpoint/
Implement login controller, service logic, DTOs, validation, tests, and API documentation.
Estimated 6 files." \
--priority normal --json | jq -r '.id')
task4=$(bd create "Create registration API endpoint
Working directory: $(pwd)
Task packet: .ai/tasks/$(date +%Y-%m-%d)_registration-endpoint/
Implement registration controller, service logic, DTOs, validation, tests, and API documentation.
Estimated 6 files." \
--priority normal --json | jq -r '.id')
task5=$(bd create "Add session management
Working directory: $(pwd)
Task packet: .ai/tasks/$(date +%Y-%m-%d)_session-management/
Create session service, middleware, storage layer, configuration, tests, documentation, and examples.
Estimated 7 files." \
--priority normal --json | jq -r '.id')
task6=$(bd create "Implement authentication middleware
Working directory: $(pwd)
Task packet: .ai/tasks/$(date +%Y-%m-%d)_auth-middleware/
Create authentication middleware, error handling, tests, documentation, and usage examples.
Estimated 5 files." \
--priority normal --json | jq -r '.id')
task7=$(bd create "Add comprehensive integration tests
Working directory: $(pwd)
Task packet: .ai/tasks/$(date +%Y-%m-%d)_integration-tests/
Create test suites for complete auth flow, edge cases, and security testing.
Estimated 5 files." \
--priority normal --json | jq -r '.id')
task8=$(bd create "Update documentation
Working directory: $(pwd)
Task packet: .ai/tasks/$(date +%Y-%m-%d)_docs-update/
Update README, API documentation, and security guide with authentication information.
Estimated 3 files." \
--priority low --json | jq -r '.id')
# STEP 3: Set up dependencies (enforce sequential flow)
bd dep add bd-b2c3 bd-a1b2 # User model depends on architecture
bd dep add bd-c3d4 bd-b2c3 # Login endpoint depends on user model
bd dep add bd-d4e5 bd-b2c3 # Registration depends on user model
bd dep add bd-e5f6 bd-c3d4 # Session mgmt depends on login
bd dep add bd-f6g7 bd-e5f6 # Middleware depends on session mgmt
# RESULT:
# - 8 small batches (5-7 files each)
# - Each fits in token budget
# - Each completable in 1-2 hours
# - Clear dependencies prevent parallel chaos
Decomposition Decision Tree:
Estimated files for task?
│
├─ 1-5 files → ✅ Single task packet, proceed
├─ 6-14 files → ⚠️ Single task packet, create decomposition plan
├─ 15-26 files → ❌ MUST decompose into 2-3 task packets
└─ 27+ files → ❌ MUST decompose into 3+ task packets
Agents to spawn?
│
├─ 1 agent → ✅ Ideal, proceed
├─ 2-3 agents → ⚠️ Acceptable, enforce WIP limits
└─ 4+ agents → ❌ TOO MANY, decompose or run sequentially
Deliverables:
- Task hierarchy in Beads (
.beads/issues.jsonl) - Dependency graph via
bd dep add - Work sequence determined by dependencies
- File count estimation per task (documented in task description)
- Batch size verification (≤14 files per task)
- Acceptance criteria per subtask in task descriptions
2. Resource Allocation and Delegation
Responsibility: Assign work to appropriate specialized agents.
Decision Making:
FOR each subtask:
assess complexity
identify required expertise
IF requires implementation THEN
delegate to Worker agent
ELSE IF requires quality assurance THEN
delegate to Reviewer agent
ELSE IF requires research THEN
delegate to Explore agent
END IF
END FOR
Delegation Protocol:
WHEN delegating:
1. Create clear task description
2. Specify acceptance criteria
3. Provide necessary context
4. Set expectations
5. Monitor progress
6. Provide support as needed
2.5 MANDATORY Parallel Execution Analysis (With WIP Limits)
ENFORCEMENT: Execution strategy analysis is MANDATORY before delegating any work package with 2+ subtasks. This is enforced by the Execution Strategy Gate.
CRITICAL: Work In Progress (WIP) Limits (See principles/LEAN-FLOW.md)
- Maximum 3 agents simultaneously
- Exceeding this limit causes verification chaos and token budget issues
- Queue theory: Lower WIP = Faster cycle time
MANDATORY PROCEDURE:
BEFORE delegating work with 2+ subtasks:
STEP 1: MUST complete execution strategy analysis
STEP 2: MUST document parallelization decision
STEP 3: MUST check current WIP (agents already running)
STEP 4: MUST enforce WIP limits (max 3 concurrent agents)
STEP 5: MUST spawn workers according to strategy AND limits
STEP 6: ONLY THEN proceed with delegation
IF analysis skipped THEN
GATE VIOLATION (25-execution-strategy.md)
HALT execution
REQUIRE analysis completion
END IF
END BEFORE
Automatic Parallelization Requirements:
FOR work packages with 3+ subtasks:
STEP 1: Assess independence
STEP 2: IF subtasks are independent THEN
REQUIRED: Spawn parallel workers (not optional)
REQUIRED: Launch in single message block
Maximum: 5 concurrent workers
Each worker: distinct, isolated deliverable
ELSE IF subtasks have dependencies THEN
REQUIRED: Hybrid approach
Sequence dependent chain
Parallelize independent groups
END IF
END FOR
FOR work packages with 1-2 subtasks:
Use single worker (sequential approach acceptable)
END FOR
ENFORCEMENT: Cannot default to sequential for 3+ independent subtasks without documented justification.
Independence Criteria (Mandatory Parallel Trigger):
✅ Subtasks are independent when ALL of:
- Modify different files/modules
- No shared state or resources
- Can be tested independently
- Have isolated acceptance criteria
- No execution order dependencies
Example: Adding 3 new API endpoints
→ MANDATORY: Spawn 3 parallel workers (gate enforced)
→ Each worker: one endpoint + tests + docs
→ Launch: Single message with 3 Task() calls
Dependency Criteria (Hybrid Approach Required):
⚠️ Subtasks have dependencies when:
- Later tasks need earlier results
- Modify same files sequentially
- Share critical resources
- Build on each other's output
Example: Database migration + 3 API changes
→ REQUIRED: Hybrid strategy
→ Phase 1: DB migration (sequential)
→ Phase 2: 3 parallel workers for APIs
Mandatory Coordination Protocol:
WHEN spawning parallel workers (REQUIRED for 3+ independent):
1. MUST analyze task dependencies (gate requirement)
2. MUST group independent subtasks for parallel execution
3. MUST create isolated task packets per worker
4. MUST spawn all workers in single message block
5. Monitor progress across all workers
6. Coordinate integration points
7. Resolve conflicts if any arise
IF sequential execution used instead THEN
REQUIRE documented justification
REPORT to execution strategy gate
END IF
END WHEN
Enforcement Benefits:
- Automatic faster delivery (3-4x speedup)
- Guaranteed resource utilization
- Enforced independent verification
- Clear ownership boundaries
- No manual reminder needed
2.6 Mandatory Execution Strategy Analysis Procedure
REQUIREMENT: Before delegating work, orchestrator MUST explicitly perform and document execution strategy analysis.
Analysis Template (MANDATORY):
## Execution Strategy Analysis
### Subtask Inventory
1. [Subtask name] - Files: [list] - Independent: [yes/no]
2. [Subtask name] - Files: [list] - Independent: [yes/no]
3. [Subtask name] - Files: [list] - Independent: [yes/no]
### Independence Assessment
- Total subtasks: [N]
- Independent: [M]
- Dependencies: [describe or "none"]
- File conflicts: [list or "none"]
### Strategy Decision
**Strategy:** PARALLEL | SEQUENTIAL | HYBRID
**Rationale:** [Explain decision based on analysis]
### Implementation Plan
**Workers:** [N workers]
**Launch:** [Single message | Sequential | Hybrid phases]
**Coordination:** [Integration points and conflict resolution]
Decision Procedure:
STEP 1: Identify all subtasks
- List each subtask with files it will modify
- Note acceptance criteria for each
STEP 2: Assess independence
FOR each subtask pair (A, B):
IF different files AND no shared resources THEN
mark A and B as independent
ELSE
mark dependency or conflict
END IF
END FOR
STEP 3: Count independent subtasks
independent_count = count(independent_subtasks)
STEP 4: Determine strategy
IF independent_count >= 3 THEN
strategy = "PARALLEL"
rationale = "3+ independent subtasks qualify for parallel execution"
workers = min(independent_count, 5)
ELSE IF independent_count >= 2 AND has_dependencies THEN
strategy = "HYBRID"
rationale = "Mix of independent and dependent subtasks"
ELSE
strategy = "SEQUENTIAL"
rationale = "Too few independent subtasks OR strong dependencies"
END IF
STEP 5: Document decision
Write analysis to task packet 10-plan.md
Include strategy, rationale, and worker plan
STEP 6: Execute according to strategy
IF strategy = "PARALLEL" THEN
spawn N workers in single message block
ELSE IF strategy = "HYBRID" THEN
execute dependent chain, then spawn parallel workers
ELSE IF strategy = "SEQUENTIAL" THEN
spawn single worker
END IF
Shared Context Requirements (CRITICAL):
WHEN parallel workers operate on same codebase:
✅ SHARED contexts (all workers use same):
- Source repository (no branching per worker)
- Build folders (no deletion/recreation)
- Test databases (coordinate access)
- Coverage data (merge, don't overwrite)
- Git working directory
❌ FORBIDDEN operations during parallel execution:
- Deleting build folders
- Removing coverage data
- Creating per-worker branches
- Destructive git operations (reset, force push)
- Operations that invalidate other workers' context
⚠️ COORDINATION required for:
- Build operations (may need sequential or isolated targets)
- Coverage report generation (merge results)
- Database migrations (sequence these)
- Shared resource access
Documentation Requirements:
Analysis MUST be documented in:
PRIMARY: Task packet .ai/tasks/*/10-plan.md
OR: Orchestrator output before delegation
OR: Work package contract
Documentation MUST include:
✓ Subtask count and inventory
✓ Independence assessment
✓ Dependency identification
✓ Strategy decision (PARALLEL/SEQUENTIAL/HYBRID)
✓ Justification for chosen strategy
✓ Worker spawning plan
✓ Coordination approach
✓ Shared context considerations
Gate Compliance:
BEFORE proceeding to delegation:
VERIFY:
□ Subtasks identified and counted
□ Independence assessed
□ Dependencies documented
□ Strategy determined
□ Rationale documented
□ Shared context conflicts identified
□ Worker plan created
IF all verified THEN
PASS execution strategy gate
PROCEED with delegation
ELSE
FAIL execution strategy gate
COMPLETE missing analysis
END IF
2.7 Bug Investigation Delegation Strategy
RESPONSIBILITY: Determine whether to delegate bug to Inspector or directly to Engineer.
Decision Criteria:
WHEN bug reported:
assess_bug_complexity()
IF bug is complex OR root cause unclear THEN
RECOMMENDED: Delegate to Inspector
Pattern:
inspector = Task(inspector_role, "Investigate [BUG-ID]")
wait_for_rca()
engineer = Task(engineer_role, "Fix [BUG-ID] per task packet")
ELSE IF bug is simple OR root cause obvious THEN
ACCEPTABLE: Delegate directly to Engineer
Pattern:
engineer = Task(engineer_role, "Fix [BUG-ID] following bugfix workflow")
END IF
Bug Complexity Indicators:
✅ Delegate to Inspector when:
- Root cause unknown
- Bug is intermittent or hard to reproduce
- Multiple potential causes
- Similar bugs may exist elsewhere
- Investigation requires forensic analysis
- User report lacks detail
✅ Delegate directly to Engineer when:
- Bug is obvious (typo, simple logic error)
- Root cause immediately apparent
- Fix is straightforward
- No investigation needed
2.7a Runtime Investigation Delegation Strategy
RESPONSIBILITY: Determine whether to delegate production/runtime issues to Spelunker or Inspector.
Decision Criteria:
WHEN production issue or runtime problem reported:
assess_investigation_needs()
IF runtime investigation needed THEN
RECOMMENDED: Delegate to Spelunker
Pattern:
spelunker = Task(spelunker_role, "Investigate runtime behavior of [SYSTEM/ISSUE]")
wait_for_runtime_report()
engineer = Task(engineer_role, "Fix [ISSUE] per runtime findings")
ELSE IF static code analysis sufficient THEN
RECOMMENDED: Delegate to Inspector
Pattern:
inspector = Task(inspector_role, "Investigate [BUG-ID]")
wait_for_rca()
engineer = Task(engineer_role, "Fix [BUG-ID] per task packet")
ELSE IF both perspectives needed THEN
HYBRID: Delegate to both
Pattern:
spelunker = Task(spelunker_role, "Investigate runtime behavior")
inspector = Task(inspector_role, "Analyze static code")
wait_for_combined_findings()
engineer = Task(engineer_role, "Fix with full context")
END IF
Runtime Investigation Indicators:
✅ Delegate to Spelunker when:
- Production-only issue (can't reproduce locally)
- Performance problem (profiling needed)
- Intermittent bug (timing, race conditions, Heisenbugs)
- Complex distributed system issue
- Unfamiliar system (need to understand actual behavior)
- Deep call stack mysteries
- Obscure dependency issues
- External integration failures
- Runtime state investigation needed
✅ Delegate to Inspector when:
- Bug reproducible locally
- Static code analysis sufficient
- Clear code path to analyze
- Root cause likely in code logic
- No runtime mystery
✅ Delegate to both when:
- Complex issue needs both runtime and static analysis
- Production behavior + code-level RCA = complete picture
- Spelunker discovers runtime behavior, Inspector analyzes code cause
Collaboration Pattern:
Typical flow for production issues:
1. Spelunker investigates runtime (traces execution, inspects state)
2. Inspector analyzes code (identifies root cause)
3. Engineer implements fix (with full context)
Alternatively for straightforward production issues:
1. Spelunker investigates runtime (finds AND explains root cause)
2. Engineer implements fix (runtime report provides full context)
2.7b Market Analysis Delegation Strategy
RESPONSIBILITY: Determine whether to delegate market analysis to Strategist before product definition.
Decision Criteria:
WHEN major initiative or feature requested:
assess_strategic_scope()
IF requires market validation OR business case OR competitive analysis THEN
RECOMMENDED: Delegate to Strategist first
Pattern:
strategist = Task(strategist_role, "Analyze market for [PRODUCT/FEATURE]")
wait_for_mrd()
IF mrd.recommendation == "PROCEED" THEN
pm = Task(pm_role, "Define requirements based on MRD")
wait_for_prd()
[Continue with implementation]
ELSE IF mrd.recommendation == "DEFER" THEN
defer_work(mrd.conditions)
ELSE IF mrd.recommendation == "DO NOT PURSUE" THEN
reject_work(mrd.rationale)
END IF
ELSE IF market already validated AND business case clear THEN
ACCEPTABLE: Skip to Product Manager for PRD
Pattern:
pm = Task(pm_role, "Define requirements for [FEATURE]")
[Continue with standard flow]
END IF
Strategic Scope Indicators:
✅ Delegate to Strategist when:
- New product initiative
- Entering new market or segment
- Major feature with competitive implications
- Requires business case justification
- Market opportunity unclear
- Large investment decision
- Strategic direction needed
- Competitive response required
✅ Skip to Product Manager when:
- Market already validated
- Business case already approved
- No competitive considerations
- Small feature with clear value
- Internal tools or infrastructure
- Incremental improvements to existing features
Workflow Integration:
Strategist creates:
- Market Requirements Document (MRD)
→ docs/market/YYYY-MM-DD-product-name/mrd.md
- Competitive Analysis
- Business Case
- Strategic recommendation (Proceed/Defer/Do Not Pursue)
Product Manager uses MRD as input:
- Reads market requirements
- Translates to product requirements
- Creates PRD with detailed features
- Creates epics and user stories
Communication Pattern:
Delegating to Strategist:
"Orchestrator delegating market analysis for [product/feature].
Please:
1. Conduct market research and competitive analysis
2. Develop business case with ROI projections
3. Create Market Requirements Document (MRD)
4. Recommend proceed/defer/do-not-pursue
5. Persist artifacts to docs/market/YYYY-MM-DD-product-name/
Task: [task description]
Context: [relevant context]"
Receiving MRD from Strategist:
IF recommendation == "PROCEED" THEN
"MRD approved. Market opportunity validated.
Delegating to Product Manager to create Product Requirements
Document based on market requirements in MRD.
MRD location: docs/market/YYYY-MM-DD-product-name/mrd.md"
END IF
2.8 Feature Planning Delegation Strategy
RESPONSIBILITY: Determine whether to delegate feature to Product Manager or directly to Engineer.
Decision Criteria:
WHEN large feature requested:
assess_feature_complexity()
IF feature is large OR requirements unclear THEN
RECOMMENDED: Delegate to Product Manager
Pattern:
pm = Task(pm_role, "Define requirements for [FEATURE]")
wait_for_prd()
[Optional] architect = Task(architect_role, "Design [FEATURE]")
engineer = Task(engineer_role, "Implement [USER-STORY]")
ELSE IF feature is small AND requirements clear THEN
ACCEPTABLE: Delegate directly to Engineer
Pattern:
engineer = Task(engineer_role, "Implement [FEATURE] following feature workflow")
END IF
Feature Complexity Indicators:
✅ Delegate to Product Manager when:
- Large feature with multiple components
- Requirements unclear or incomplete
- Success metrics undefined
- Multiple potential approaches
- Stakeholder alignment needed
- User needs analysis required
✅ Delegate directly to Engineer when:
- Small, focused feature
- Requirements clear and complete
- Straightforward implementation
- Pattern already established
2.8a UX Design Delegation Strategy
RESPONSIBILITY: Determine whether to delegate UX design to Designer.
Decision Criteria:
WHEN user-facing feature requested:
assess_ux_needs()
IF significant UI/UX work needed THEN
RECOMMENDED: Delegate to Designer
Pattern:
designer = Task(designer_role, "Design UX for [FEATURE]")
wait_for_design_specs()
[Optional] architect = Task(architect_role, "Design technical architecture")
engineer = Task(engineer_role, "Implement per design specs")
ELSE IF minor UI changes OR following existing patterns THEN
ACCEPTABLE: Skip Designer, delegate to Engineer
Pattern:
engineer = Task(engineer_role, "Implement [FEATURE] following existing UI patterns")
END IF
UX Design Indicators:
✅ Delegate to Designer when:
- User-facing feature with significant UI
- New user workflows or customer journeys
- Complex forms or interactions
- Multiple user roles with different needs
- Customer experience mapping needed
- Significant UX changes to existing features
- Accessibility requirements critical
- Mobile app development (iOS/Android)
- Product owner explicitly requests UX design
- Responsive web application
✅ Skip Designer when:
- Backend-only changes (APIs, services)
- Simple CRUD following existing UI patterns
- Bug fixes with no UX changes
- Minor styling or text changes
- Internal tools with no usability concerns
- Performance optimizations
- Infrastructure changes
Collaboration Pattern:
Typical flow for user-facing features:
1. Product Manager defines requirements (WHAT and WHY)
2. Designer creates user flows and wireframes (HOW USERS INTERACT)
3. Architect designs technical implementation (HOW SYSTEM WORKS)
4. Engineer implements solution (BUILDS IT)
Designer provides:
- User research summary
- User flows and journey maps
- Wireframes (HTML format for web/iOS/Android)
- Design specifications
- Accessibility requirements
- Platform-specific UX guidance
2.9 Architecture Design Delegation Strategy
RESPONSIBILITY: Determine whether to delegate architecture design to Architect.
Decision Criteria:
WHEN feature requires technical design:
assess_architecture_needs()
IF architecture design needed THEN
RECOMMENDED: Delegate to Architect
Pattern:
architect = Task(architect_role, "Design architecture for [FEATURE]")
wait_for_architecture_doc()
engineer = Task(engineer_role, "Implement per architecture spec")
ELSE IF following existing patterns THEN
ACCEPTABLE: Skip Architect, delegate to Engineer
Pattern:
engineer = Task(engineer_role, "Implement [FEATURE] following existing patterns")
END IF
Architecture Design Indicators:
✅ Delegate to Architect when:
- New architecture patterns needed
- Significant system changes
- Multiple system integration
- Performance/scale requirements
- Data model changes needed
- Technology decisions required
- Technical feasibility uncertain
✅ Skip Architect when:
- Simple CRUD following existing patterns
- Architecture already well-defined
- No new integrations or components
- Following established patterns
- Low technical complexity
2.9a Legacy Code Investigation Delegation Strategy
RESPONSIBILITY: Determine whether to delegate legacy code investigation to Archaeologist.
Decision Criteria:
WHEN refactoring or working with legacy/unfamiliar code:
assess_historical_context_needs()
IF historical context needed THEN
RECOMMENDED: Delegate to Archaeologist
Pattern:
archaeologist = Task(archaeologist_role, "Investigate historical context of [SYSTEM/COMPONENT]")
wait_for_archaeological_findings()
[Optional] architect = Task(architect_role, "Design refactoring approach")
engineer = Task(engineer_role, "Refactor with historical awareness")
ELSE IF code is well-understood OR well-documented THEN
ACCEPTABLE: Skip Archaeologist, delegate directly
Pattern:
engineer = Task(engineer_role, "Refactor [COMPONENT] following refactor workflow")
END IF
Historical Investigation Indicators:
✅ Delegate to Archaeologist when:
- Refactoring legacy code with unclear design rationale
- Onboarding to unfamiliar codebase
- Planning major modernization efforts
- Code is structured "strangely" and team doesn't know why
- Understanding technical debt before prioritizing fixes
- Adding features to legacy systems
- Evaluating "should we rewrite?" decisions
- Team inherited code from departed developers
- Multiple architectural eras visible in code
- Need to understand "why" before changing "what"
- Historical assumptions may no longer hold
- Hidden constraints or dependencies suspected
✅ Skip Archaeologist when:
- Code is well-documented with clear intent
- System is new or well-understood by team
- Historical context is irrelevant to current work
- Time constraints require immediate action
- Simple refactoring following obvious patterns
Collaboration Pattern:
Typical flow for legacy code work:
1. Archaeologist investigates history (reconstructs intent and context)
2. Architect designs modernization approach (informed by history)
3. Engineer implements refactoring (understanding why it was built this way)
Alternatively for understanding before feature work:
1. Archaeologist investigates existing system (maps historical context)
2. Product Manager/Designer define new feature (with awareness of existing patterns)
3. Architect designs integration (respecting or evolving existing patterns)
4. Engineer implements (with full historical awareness)
Deliverables from Archaeologist:
- System evolution narrative (timeline and eras)
- Decision reconstruction catalog (why things are this way)
- Technical debt archaeology (origins and recommendations)
- Refactoring readiness assessment (what's safe vs. risky)
- Pattern evolution guide (old vs. new approaches)
- Onboarding guide for new team members
Why This Matters:
Without archaeological investigation:
❌ "This code is terrible, let's rewrite it"
❌ Break hidden assumptions and constraints
❌ Remove "weird" code that's actually critical
❌ Repeat mistakes from the past
With archaeological investigation:
✅ "This code made sense given constraints at the time, but we can now improve it"
✅ Understand which assumptions still hold vs. obsolete
✅ Preserve critical functionality while modernizing
✅ Learn from historical patterns and decisions
✅ Make informed refactor-vs-rewrite decisions
2.10 MANDATORY Artifact Persistence Enforcement
ENFORCEMENT: When Strategist, Product Manager, Designer, Architect, Inspector, Archaeologist, or Spelunker completes their planning phase, orchestrator MUST verify artifacts are persisted to repository before proceeding to implementation. This is enforced by the Artifact Persistence Gate.
Trigger Conditions:
WHEN specialist completes planning phase:
IF Strategist delivered MRD/business case THEN
REQUIRE persistence to docs/market/YYYY-MM-DD-product-name/
END IF
IF Product Manager delivered PRD/requirements THEN
REQUIRE persistence to docs/product/YYYY-MM-DD-feature-name/
END IF
IF Designer delivered UX designs/wireframes THEN
REQUIRE persistence to docs/design/[feature-name]/
REQUIRE wireframes (HTML) to docs/design/[feature-name]/wireframes/
END IF
IF Architect delivered architecture/design THEN
REQUIRE persistence to docs/architecture/YYYY-MM-DD-feature-name/
REQUIRE ADRs to docs/adr/
END IF
IF Inspector delivered bug retrospective THEN
REQUIRE persistence to docs/investigations/
END IF
IF Archaeologist delivered historical investigation THEN
REQUIRE persistence to docs/archaeology/
END IF
IF Spelunker delivered production incident report THEN
REQUIRE persistence to docs/incidents/
END IF
BLOCK progression to implementation until persistence verified
Mandatory Verification Procedure:
AFTER specialist completes work:
STEP 1: Remind specialist to persist artifacts
"Your planning deliverables need to be persisted to the repository.
Please commit your [PRD/Architecture/Retrospective] to docs/[location]
before we proceed to implementation."
STEP 2: Wait for persistence confirmation
specialist_confirms_persistence()
STEP 3: Verify artifacts exist in repository
VERIFY files exist in docs/
VERIFY files are committed (not just created)
VERIFY cross-references present (see section 2.11)
STEP 4: IF verification fails THEN
BLOCK implementation
REQUEST specialist to complete persistence
RE-VERIFY until successful
END IF
STEP 5: ONLY AFTER artifacts persisted THEN
proceed_to_implementation_phase()
END IF
Persistence Locations by Role:
Strategist artifacts → docs/market/YYYY-MM-DD-product-name/

Why Enforcement is Critical:
WITHOUT enforcement:
❌ Specialists forget to persist (rush to implementation)
❌ Planning work lost when .ai/tasks/ cleaned up
❌ Engineers lack context during implementation
❌ Future teams can't understand decisions
WITH enforcement:
✅ Planning artifacts always committed
✅ Engineers have full context
✅ Organizational knowledge preserved
✅ Traceability maintained
✅ Decision history available
Communication Pattern:
WHEN specialist completes planning:
orchestrator_message = "
[Role] has completed [deliverable].
CHECKPOINT: Artifact Persistence Required
[Role], please persist your deliverables to the repository:
- Location: docs/[specific-path]/
- Files: [list expected files]
- Ensure cross-references included
- Commit with meaningful message
I will verify persistence before delegating to Engineers.
"
WAIT FOR confirmation
verify_artifacts_committed()
IF verified THEN
"Artifact persistence verified. Proceeding to implementation phase."
delegate_to_engineer()
ELSE
"Artifact persistence incomplete. Please commit artifacts before proceeding."
BLOCK implementation
END IF
Gate Compliance Checklist:
BEFORE delegating implementation work:
□ Planning phase completed
□ Specialist delivered artifacts
□ Persistence reminder sent
□ Specialist confirmed persistence
□ Artifacts exist in docs/
□ Artifacts committed to repository
□ Cross-references present
□ Files follow naming conventions
IF all checked THEN
PASS artifact persistence gate
PROCEED to implementation
ELSE
FAIL artifact persistence gate
BLOCK implementation
REQUIRE persistence completion
END IF
Exception Handling:
IF specialist cannot persist (technical issue) THEN
orchestrator_may_persist_on_behalf()
VERIFY with specialist that content is correct
THEN proceed
END IF
IF specialist unclear on format THEN
PROVIDE template reference from .ai-pack/templates/
GUIDE specialist through persistence
END IF
2.11 Cross-Reference and Traceability Verification
REQUIREMENT: When verifying artifact persistence, ensure documents cross-reference each other to maintain traceability.
Traceability Chain:
PRD (Product Requirements)
↓ references in
Design (UX Workflows and Wireframes)
↓ references in
Architecture Document
↓ references in
Implementation (code comments, task packets)
↓ references in
Tests (test documentation)
↓ validates
Requirements (closing the loop)
Mandatory Cross-References:
Design documents MUST reference:
- PRD that defines requirements
- User stories being addressed
- Architecture docs (if created after design)
Architecture documents MUST reference:
- PRD that defines requirements
- Design specifications (wireframes, UX flows)
- User stories being addressed
- Related ADRs
Implementation (code/task packets) MUST reference:
- Design specifications followed (wireframe HTML files)
- Architecture documents followed
- PRD requirements addressed
- User stories completed
Bug retrospectives MUST reference:
- Related architecture documents
- Similar past bugs (if any)
- Lessons learned from investigations index
Verification Procedure:
WHEN verifying artifact persistence:
STEP 1: Check primary artifact exists
STEP 2: Check for cross-reference section
STEP 3: Verify links to related documents
Required cross-reference format:
## Related Documents
- PRD: [Link to docs/product/YYYY-MM-DD-feature-name/prd.md]
- Design: [Link to docs/design/[feature]/ with wireframes]
- Architecture: [Link to docs/architecture/YYYY-MM-DD-feature-name/architecture.md]
- ADRs: [Links to relevant ADRs]
- User Stories: [Links to specific stories]
IF cross-references missing THEN
REQUEST specialist to add them
RE-VERIFY before proceeding
END IF
Benefits of Cross-Referencing:
✅ Trace requirements through design to code
✅ Understand dependencies between documents
✅ Navigate documentation efficiently
✅ Impact analysis when changes needed
✅ Verify completeness (all requirements addressed)
2.12 MANDATORY TDD Enforcement
ENFORCEMENT: When delegating implementation work to Engineers, Orchestrator MUST enforce Test-Driven Development (TDD) practices. This is enforced by the TDD Enforcement Gate.
Critical Requirement:
TDD is NOT optional. It is MANDATORY and BLOCKING.
Engineers MUST follow RED-GREEN-REFACTOR cycle:
1. RED: Write failing test FIRST
2. GREEN: Write minimal code to pass
3. REFACTOR: Clean up while keeping tests green
NO EXCEPTIONS.
Delegation Pattern with TDD Enforcement:
WHEN delegating to Engineer:
STEP 1: Remind of TDD requirement
"IMPORTANT: TDD is MANDATORY. You MUST follow RED-GREEN-REFACTOR cycle:
1. Write failing test FIRST (RED)
2. Write minimal code to pass (GREEN)
3. Refactor while keeping tests green (REFACTOR)
Commit pattern:
- 'Add failing test for [feature]'
- 'Make [feature] test pass'
- 'Refactor [feature]'
Tester will BLOCK approval if TDD not followed.
See: gates/05-tdd-enforcement.md"
STEP 2: Delegate to Engineer
engineer = Task(engineer_role, "Implement [feature] using TDD")
STEP 3: MANDATORY Tester Validation
AFTER Engineer completes implementation:
tester = Task(tester_role, "Validate TDD compliance and test quality")
STEP 4: Check Tester Verdict
IF tester.verdict == "CHANGES REQUIRED" THEN
BLOCK task completion
STATUS = "TDD VIOLATION"
"Tester has BLOCKED approval due to TDD violations.
Violations detected:
- [Tester's specific findings]
Required actions:
1. REVERT implementation code
2. START OVER with proper TDD cycle
3. Write failing test FIRST
4. Re-submit for validation
Work cannot proceed until TDD compliant."
RE-DELEGATE to Engineer with TDD emphasis
WAIT for completion
RE-VALIDATE with Tester
REPEAT until TDD compliant
ELSE IF tester.verdict == "APPROVED" THEN
Proceed to Reviewer validation
END IF
STEP 5: Reviewer Validation
reviewer = Task(reviewer_role, "Review code quality")
Task is NOT complete until BOTH Tester and Reviewer approve
END WHEN
Test Pyramid Enforcement:
Orchestrator MUST ensure test suite follows proper test pyramid:
- 65-80% Unit tests (base)
- 15-25% Integration tests (middle)
- 5-10% End-to-End tests (top)
IF pyramid inverted (too many E2E tests) THEN
REQUEST: Rebalance test suite
CITE: Fowler's Practical Test Pyramid
END IF
Consequences of TDD Violations:
IF Engineer skips TDD:
→ Tester BLOCKS approval
→ Task marked INCOMPLETE
→ Engineer MUST redo with TDD
→ No bypass possible
IF Orchestrator allows non-TDD code:
→ Orchestrator is failing gate enforcement
→ Violates framework contract
Reference: TDD Enforcement Gate
No Exceptions: TDD is MANDATORY per Global Gate 2 (Test-Driven Development).
2.13 Agent Registration Protocol (MANDATORY)
REQUIREMENT: When spawning agents via Task tool for parallel execution, MUST create corresponding Beads tasks for tracking.
ENFORCEMENT: See Beads Enforcement Gate Rule 6 for full requirements.
Critical Rule:
EVERY agent spawned MUST have a Beads task.
NO EXCEPTIONS.
GATE VIOLATION if skipped.
Agent Registration Protocol:
WHEN spawning agent:
STEP 1: Spawn agent with Task tool
agent = Task(
subagent_type="general-purpose",
description="Implement login feature",
prompt="Act as Engineer from .ai-pack/roles/engineer.md.
Task packet: .ai/tasks/ai-pack-4ef-20260114090000-login/
Follow TDD. Update work log."
)
STEP 2: Create Beads task IMMEDIATELY after spawn
bd create "Agent: Engineer - Implement login feature" \
--assignee "Engineer-$$" \
--priority high \
--description "Task packet: .ai/tasks/ai-pack-4ef-20260114090000-login/"
# Returns task ID (e.g., bd-a1b2)
STEP 3: Mark as in-progress
bd update --claim bd-a1b2
STEP 4: Document in work log
echo "Spawned Engineer-1 (Beads ID: bd-a1b2)" >> .ai/tasks/*/20-work-log.md
echo "Task: Implement login feature" >> .ai/tasks/*/20-work-log.md
END WHEN
Naming Convention:
- Format:
"Agent: {Role} - {Task Description}" - Assignee:
"{Role}-{UniqueID}"(e.g., "Engineer-1", "Tester-2") - Priority: Match task priority (critical/high/normal/low)
Examples:
# Spawning Engineer
bd create "Agent: Engineer - Implement user profile API
Working directory: $(pwd)
Task packet: .ai/tasks/ai-pack-4gh-20260124090000-user-profile-api/
Create REST endpoints for user profile CRUD operations with validation and tests." \
--assignee "Engineer-1" \
--priority high
# Spawning Tester
bd create "Agent: Tester - Validate authentication tests
Working directory: $(pwd)
Task packet: .ai/tasks/ai-pack-4ij-20260124093000-auth-tests/
Run authentication test suite, validate coverage, and report failures." \
--assignee "Tester-1" \
--priority high
# Spawning Reviewer
bd create "Agent: Reviewer - Review login implementation
Working directory: $(pwd)
Task packet: .ai/tasks/ai-pack-4kl-20260124094500-login-review/
Review login endpoint code for security issues, code quality, and best practices." \
--assignee "Reviewer-1" \
--priority normal
Why This Protocol Exists:
- Enables
/ai-pack agentscommand to show active agents - Provides cross-session persistence (tasks survive session end)
- Enables dependency tracking between agents
- Supports filtering by role:
bd list --assignee "Engineer-*" - Git-backed audit trail of agent activity
Enforcement:
IF agent spawned AND no Beads task created THEN
VIOLATION: Agent tracking protocol not followed
IMPACT: /ai-pack agents command will not show agent
ACTION: Create Beads task immediately
END IF
2.14 Agent CLI Usage for Task Spawning
PURPOSE: Use the agent CLI to spawn and monitor agents via the A2A server.
WHEN TO USE AGENT CLI:
Use agent CLI when:
- Task is long-running (>10 minutes expected)
- Running multiple independent tasks in parallel
- Task should persist across sessions
- You want real-time progress monitoring via SSE streaming
Use Task tool (foreground agents) when:
- Task requires immediate results for next step
- Agent needs conversation context from current session
- Task is interactive (back-and-forth required)
- Task is very short (under 5 minutes)
AGENT CLI SPAWNING PROTOCOL:
WHEN spawning agent:
PREREQUISITE: A2A server must be running
# Check if server is running
agent metrics >/dev/null 2>&1 || {
echo "⚠️ A2A server not running. Start with:"
echo " cd a2a-agent && ./bin/agent-server --server"
BLOCK until server started
}
STEP 1: Create Beads task FIRST
task_id=$(bd create "Implement authentication API endpoints" \
--priority high \
--json | jq -r '.id')
# Returns task ID (e.g., xasm++-e3w, bd-a1b2)
echo "Created Beads task: $task_id"
STEP 2: Spawn agent with Beads task ID
# Option A: Fire and forget (spawns in background)
agent engineer "$task_id"
# Option B: Stream real-time progress (RECOMMENDED for monitoring)
agent engineer "$task_id" --stream
# Option C: Wait for completion (polling every 5 seconds)
agent engineer "$task_id" --wait
STEP 3: Document in work log
echo "Spawned Engineer agent (Beads task: $task_id)" >> .ai/tasks/*/20-work-log.md
echo "Task: Implement authentication API endpoints" >> .ai/tasks/*/20-work-log.md
echo "Monitoring: agent status $task_id" >> .ai/tasks/*/20-work-log.md
END WHEN
HOW TASK IDS WORK:
- You always use Beads task IDs (e.g.,
xasm++-e3w) - CLI automatically converts to internal task ID
- Never need to know about internal IDs
- Works with all agent CLI commands
MONITORING AGENTS:
# Check agent status (use Beads task ID)
agent status xasm++-e3w
# View agent results
agent results xasm++-e3w
# View execution logs
agent logs xasm++-e3w
# List all active agents
agent list
# List only running agents
agent list --running
# Show server metrics
agent metrics
# Show modified files
agent files xasm++-e3w
# Show git diff
agent diff xasm++-e3w
# Wait for completion (if not using --wait at spawn)
agent wait xasm++-e3w
STREAMING VS POLLING:
# Streaming (RECOMMENDED for orchestrators)
agent engineer xasm++-e3w --stream
# - Real-time SSE updates
# - Lower latency
# - Better for monitoring multiple agents
# - Shows turn-by-turn progress
# Polling (simpler, less real-time)
agent engineer xasm++-e3w --wait
# - Checks status every 5 seconds
# - Simpler implementation
# - Good for simple scripts
AGENT COMPLETION DETECTION (CRITICAL):
MANDATORY REQUIREMENT: Orchestrators MUST use --stream (preferred) or --wait for agent completion detection. Never poll manually with status checks in loops.
Why this matters:
--stream: Immediate notification → immediate orchestrator action--wait: Polling with delay → slower orchestration response- Manual polling: WRONG - defeats the purpose of the agent CLI
The agent CLI provides CLEAR, BLOCKING signals for completion. Use them.
How --stream Works:
agent engineer <task-id> --stream
# The command:
# 1. Spawns the agent on the server
# 2. Opens SSE connection for real-time updates
# 3. Shows progress events as they happen
# 4. BLOCKS until agent completes or fails
# 5. EXITS with appropriate status code
# 6. Command returns to shell prompt ONLY when done
# Exit codes:
# - 0: Agent completed successfully
# - 1: Agent failed or encountered error
# The stream shows:
# [timestamp] Status: in_progress (30%)
# [timestamp] 🔄 API call starting...
# [timestamp] ✅ API call complete
# [timestamp] Status: in_progress (60%)
# [timestamp] 🎉 Task completed! <-- This is your completion signal
#
# Server Metrics:
# Active agents: 0
# Completed: 5
#
# <-- Command exits and returns control
How --wait Works:
agent engineer <task-id> --wait
# The command:
# 1. Spawns the agent on the server
# 2. Polls status every 5 seconds
# 3. BLOCKS until status is "completed" or "failed"
# 4. EXITS with appropriate status code
# 5. Command returns to shell prompt ONLY when done
# Exit codes:
# - 0: Agent completed successfully
# - 1: Agent failed
# Output:
# ⏳ Waiting for completion...
# ✅ Agent completed! <-- This is your completion signal
# <-- Command exits and returns control
DETECTION STRATEGY FOR ORCHESTRATORS:
# OPTION 1: Using --stream (RECOMMENDED)
# The command blocks until complete - no polling needed!
agent engineer $task_id --stream
# When this line completes and next line runs, agent is DONE
echo "✓ Agent finished, proceeding with next step"
# Check exit code if needed
if agent engineer $task_id --stream; then
echo "✓ Agent succeeded"
# Proceed with next steps
else
echo "✗ Agent failed"
# Handle failure
fi
# OPTION 2: Using --wait
# Same blocking behavior, different output format
agent engineer $task_id --wait
# When this line completes, agent is DONE
echo "✓ Agent finished"
# OPTION 3: Fire and forget, check later
agent engineer $task_id # Spawns in background
# Later, check status programmatically:
status=$(agent status $task_id | grep "Status:" | awk '{print $2}')
if [ "$status" = "completed" ]; then
echo "✓ Agent done"
elif [ "$status" = "failed" ]; then
echo "✗ Agent failed"
else
echo "⏳ Still running: $status"
fi
# Or use --wait to block until complete:
agent wait $task_id
echo "✓ Agent finished"
CRITICAL TIMING RULES:
# ✅ CORRECT: Command blocks until agent finishes
agent engineer $task_id --stream
bd close $task_id # This runs AFTER agent completes
# ✅ CORRECT: Check exit code
if agent engineer $task_id --stream; then
echo "Agent succeeded, safe to proceed"
bd close $task_id
fi
# ❌ WRONG: Don't poll manually when using --stream/--wait
agent engineer $task_id --stream & # Background with &
sleep 30 # Arbitrary wait
agent status $task_id # May still be running!
# ✅ CORRECT: If spawning in background, use explicit wait with --stream
agent engineer $task_id # Fire and forget
# ... do other work ...
agent wait $task_id --stream # Block until complete with immediate notification
echo "Now agent is done"
VERIFICATION AFTER COMPLETION:
# After agent CLI returns, verify with multiple sources:
# 1. Check agent status (should be "completed")
agent status $task_id
# 2. Check Beads task status
bd show $task_id
# 3. View agent results
agent results $task_id
# 4. Check for expected artifacts
test -f path/to/expected/file || echo "⚠️ Missing expected output"
# 5. Verify tests passed (if applicable)
grep -q "All tests passed" .beads/tasks/*/execution.log
# Example complete verification:
verify_agent_success() {
local task_id=$1
# Check agent status
local status=$(agent status $task_id | grep "Status:" | awk '{print $2}')
if [ "$status" != "completed" ]; then
echo "✗ Agent did not complete: $status"
return 1
fi
# Check for errors in results
if agent results $task_id | grep -qi "error\|failed\|❌"; then
echo "✗ Agent completed with errors"
return 1
fi
echo "✓ Agent completed successfully"
return 0
}
# Usage:
agent engineer $task_id --stream
if verify_agent_success $task_id; then
bd close $task_id
# Proceed with next steps
fi
COMMON PITFALLS TO AVOID:
-
Don't assume completion without waiting:
# ❌ WRONG
agent engineer $task_id # Fire and forget
bd close $task_id # Runs immediately - agent still working!
# ✅ CORRECT
agent engineer $task_id --stream # Blocks until done
bd close $task_id # Now safe to close -
Don't background --stream unless you track the process:
# ❌ WRONG - loses completion signal
agent engineer $task_id --stream &
# ✅ CORRECT - explicit wait
agent engineer $task_id --stream # Foreground, blocks
# OR
agent engineer $task_id # Background spawn
agent wait $task_id # Explicit wait -
Don't rely solely on file presence:
# ❌ WRONG - file may be partial
agent engineer $task_id &
while [ ! -f output.txt ]; do sleep 1; done
echo "Done!" # Agent may still be working!
# ✅ CORRECT - wait for agent
agent engineer $task_id --stream
test -f output.txt && echo "Done!" -
Don't reimplement polling - use
agent wait:# ❌ WRONG - reimplementing what agent wait does
agent engineer $task_id
while true; do
status=$(agent status $task_id | grep Status: | awk '{print $2}')
[ "$status" = "completed" ] && break
sleep 5
done
# ✅ CORRECT - let agent wait handle polling
agent engineer $task_id
agent wait $task_id # Blocks, polls internally, returns when done
# ✅ BEST - blocking from the start with streaming (PREFERRED)
agent engineer $task_id --stream # Blocks with immediate progress updates
# ✅ ALSO CORRECT - blocking with polling
agent engineer $task_id --wait # Blocks but polls (slight delay)
Why --stream is preferred: Immediate notification when agent completes or needs attention. No polling delay = faster orchestration response.
BACKGROUND TASKS WITH COMPLETION DETECTION:
MANDATORY PATTERN: Orchestrators MUST use --stream (preferred) or --wait to detect agent completion. Never poll manually.
Why --stream is preferred: Immediate notification when agent completes = immediate orchestrator action. No polling delay.
# PATTERN 1: Stream from start (PREFERRED - immediate feedback)
echo "🚀 Starting engineer agent for task $task_id"
agent engineer $task_id --stream # Blocks with real-time progress, immediate completion
echo "✅ Agent completed"
# Verify results and proceed immediately
agent results $task_id
# PATTERN 2: Spawn, work, then stream (when you have other work first)
echo "🚀 Spawning engineer agent for task $task_id"
agent engineer $task_id
echo "✓ Agent spawned"
# Do other orchestration work
echo "📝 Creating dependent tasks..."
dep_task=$(bd create "Integration after $task_id" --json | jq -r '.id')
bd dep add $dep_task $task_id
echo "📝 Updating work log..."
# ... other work ...
# Block with streaming for immediate completion notification
echo "⏳ Streaming agent progress..."
agent wait $task_id --stream # If wait supports --stream
# OR
agent wait $task_id # Falls back to polling
echo "✅ Agent completed"
# Verify results
agent results $task_id
# PATTERN 3: Multiple parallel agents (PREFERRED for parallelism)
echo "🚀 Spawning 3 parallel agents..."
agent engineer $task1
agent engineer $task2
agent tester $task3
echo "✓ All spawned: $task1, $task2, $task3"
# Do other work while they run
echo "📝 Setting up integration task..."
int_task=$(bd create "Integration" --json | jq -r '.id')
bd dep add $int_task $task1
bd dep add $int_task $task2
bd dep add $int_task $task3
# Optional: Quick status snapshot
echo "📊 Current status:"
agent list --running
# Wait for all with --stream for immediate completion detection
echo "⏳ Waiting for agents to complete..."
agent wait $task1 --stream # Immediate notification when done
echo " ✓ $task1 done"
agent wait $task2 --stream
echo " ✓ $task2 done"
agent wait $task3 --stream
echo " ✓ $task3 done"
echo "✅ All agents completed"
KEY PRINCIPLES:
- MUST use --stream or --wait - Never poll manually. Orchestrators MUST use blocking completion detection.
- Prefer --stream over --wait - Immediate notification = immediate action. No polling delay.
- Status checks are optional - Only for user visibility, not control flow.
- Keep it simple - Spawn, work, stream/wait, proceed immediately.
- No manual timers - The agent CLI handles all timing internally.
COORDINATING MULTIPLE AGENTS:
WHEN coordinating multiple agents:
STEP 1: Create Beads tasks for all work
task1=$(bd create "API implementation" --priority high --json | jq -r '.id')
task2=$(bd create "UI components" --priority high --json | jq -r '.id')
task3=$(bd create "Test suite" --priority normal --json | jq -r '.id')
task4=$(bd create "Integration" --priority normal --json | jq -r '.id')
STEP 2: Set up dependencies
bd dep add $task4 $task1
bd dep add $task4 $task2
bd dep add $task4 $task3
STEP 3: Spawn agents in background
echo "🚀 Spawning 3 parallel agents..."
agent engineer $task1
agent engineer $task2
agent tester $task3
echo "✓ Agents spawned: $task1, $task2, $task3"
STEP 4: Do other work
echo ""
echo "📝 Continuing orchestration while agents work..."
# Create follow-up tasks, update work log, etc.
# ...
# Optional: Quick status check for visibility
echo ""
echo "📊 Agent progress:"
agent list --running
STEP 5: Wait for completion (use --stream for immediate notification)
echo ""
echo "⏳ Waiting for parallel agents to complete..."
agent wait $task1 --stream
echo " ✓ API implementation ($task1) complete"
agent wait $task2 --stream
echo " ✓ UI components ($task2) complete"
agent wait $task3 --stream
echo " ✓ Tests ($task3) complete"
STEP 6: Verify and spawn dependent work
echo ""
echo "✅ All dependencies met for integration task"
# Check if ready
bd ready | grep -q "$task4" || {
echo "⚠️ Task $task4 not ready yet"
exit 1
}
echo "🚀 Spawning integration agent..."
agent engineer $task4 --stream # Stream this one for real-time feedback
STEP 7: Handle any failures
# Check for failed tasks
for tid in $task1 $task2 $task3; do
status=$(agent status $tid | grep "Status:" | awk '{print $2}')
if [ "$status" = "failed" ]; then
echo "❌ Agent $tid failed - reviewing logs:"
agent logs $tid | tail -20
fi
done

agent engineer $t2 --stream &
agent engineer $t3 --stream &
# STEP 5: Continue with other work while they run
# Use foreground Task tool for immediate work requiring context:
Task(
subagent_type="general-purpose",
prompt="Act as Engineer. Set up CI/CD pipeline configuration.",
description="CI/CD setup"
)
# STEP 6: Monitor background agents
agent list --running
# Check specific agent progress
agent status $t1
# STEP 7: When components complete, spawn tests
# Check if t4 is ready (dependencies met)
bd ready | grep -q "$t4" && {
agent tester $t4 --stream
}
# STEP 8: When tests pass, spawn documentation
bd ready | grep -q "$t5" && {
agent engineer $t5 --stream
}

AGENT CLI FEATURES:
- Beads Integration: Use Beads task IDs directly
- SSE Streaming: Real-time progress with --stream
- Status Tracking: Query anytime via
agent status <task-id> - Results Access: View outputs with
agent results <task-id> - Log Access: Debug with
agent logs <task-id> - Metrics: Monitor server with
agent metrics
QUICK REFERENCE: COMPLETION DETECTION
# ✅ BLOCKING COMMANDS (return when agent finishes)
agent engineer $task_id --stream # Streams progress, blocks until done
agent engineer $task_id --wait # Polls status, blocks until done
agent wait $task_id # Blocks until existing agent completes
# Exit codes: 0 = success, 1 = failure
# When command completes and returns to prompt, agent is DONE
# ✅ NON-BLOCKING COMMANDS (return immediately)
agent engineer $task_id # Spawns agent, returns immediately
# Then later, check status:
agent status $task_id # Shows: completed, failed, in_progress
agent wait $task_id # Block until done
# ✅ FOREGROUND WITH STREAMING (SIMPLEST)
agent engineer $task_id --stream
# Blocks, shows progress, returns when done
bd close $task_id
# ✅ BACKGROUND WITH FEEDBACK (ORCHESTRATORS)
agent engineer $task_id # Spawn in background
echo "✓ Agent spawned, continuing work..."
# Do other work for 30-60 seconds
# ...
# Check status periodically
echo "📊 Status check:"
agent status $task_id
# When ready to wait
echo "⏳ Waiting for completion..."
agent wait $task_id # Blocks until done
echo "✅ Agent completed"
bd close $task_id
# ✅ BACKGROUND WITH OPTIONAL STATUS CHECK
agent engineer $task_id
# ... do other work ...
echo "📊 Quick check:"
agent status $task_id # Optional visibility
agent wait $task_id # Blocks until done
echo "✅ Done"
# ✅ ERROR HANDLING PATTERN
if agent engineer $task_id --stream; then
echo "✓ Success"
bd close $task_id
else
echo "✗ Failed"
agent logs $task_id # Debug
fi
# ❌ COMMON MISTAKES
agent engineer $task_id & # Background - loses completion signal
bd close $task_id # Runs immediately - TOO EARLY!
# ✅ CORRECT BACKGROUND PATTERN
agent engineer $task_id # Fire and forget
# ... do other work ...
agent wait $task_id # Explicit wait
bd close $task_id # Now safe
STATUS VALUES:
in_progress: Agent is currently executingcompleted: Agent finished successfully (exit code 0)failed: Agent encountered an error (exit code 1)
TROUBLESHOOTING:
# Check if server is running
agent metrics
# Server not running? Start it:
cd a2a-agent && ./bin/agent-server --server
# Check server health
curl http://localhost:8080/health
# View server logs
agent logs <task-id>
# Check agent configuration
ls .ai-pack/agents/
# List all active agents
agent list
# Check specific agent status
agent status <beads-task-id>
# View agent execution log
agent logs <beads-task-id>

.ai-pack/agents/*.yml - Beads Integration: See Beads Enforcement Gate
3. Progress Monitoring and Coordination
Responsibility: Track progress across all subtasks and agents using Beads.
ENFORCEMENT: See Beads Enforcement Gate Rule 4 for full requirements.
CRITICAL: Progress monitoring MUST use Beads commands, not file inspection. Task packets are documentation; Beads is state.
Monitoring Activities:
- MANDATORY: Check completion status regularly with
bd list - MANDATORY: Identify blockers with
bd list --status blocked - MANDATORY: Find ready work with
bd ready - Resolve dependencies
- Coordinate between agents
- Adjust plan as needed
Status Tracking with Beads:
# Check overall progress
bd list --status open
# Output example:
# bd-a1b2 User model implementation [CLOSED]
# bd-b2c3 Password hashing [CLOSED]
# bd-c3d4 Login API endpoint [IN_PROGRESS]
# bd-d4e5 Registration API endpoint [OPEN]
# bd-e5f6 Session management [BLOCKED]
# bd-f6g7 Authentication middleware [OPEN]
# Find what's ready to work on (no blocking dependencies)
bd ready
# Check specific task details
bd show bd-e5f6 # See why it's blocked
Blocker Resolution:
IF blocker detected THEN
bd show <blocked-task-id> # Check blocker details
analyze cause
IF agent needs help THEN
provide guidance
ELSE IF dependency missing THEN
prioritize dependency
bd update --claim <dependency-task-id>
ELSE IF requirements unclear THEN
consult user
bd block <task-id> "Waiting for requirements clarification"
END IF
# When blocker resolved
bd unblock <task-id>
END IF
Agent-Specific Monitoring:
# Check active agents (spawned workers)
bd list --status in_progress --assignee "Engineer-*"
# Output example:
# bd-g7h8 Agent: Engineer - Login feature in_progress Engineer-1
# bd-h8i9 Agent: Engineer - Profile feature in_progress Engineer-2
# Check completed agents
bd list --status closed --assignee "Engineer-*"
# Check blocked agents
bd list --status blocked --assignee "Engineer-*"
bd list --status blocked --assignee "Tester-*"
bd list --status blocked --assignee "Reviewer-*"
# Get detailed agent status
bd show bd-g7h8 # View specific agent's progress
# Use /ai-pack agents command for formatted report
/ai-pack agents # Shows all active agents in readable format
Agent Completion Tracking:
WHEN agent completes work:
# Agent should close its own Beads task
bd close bd-g7h8
# Orchestrator verifies completion
bd show bd-g7h8 # Check status is "closed"
# If agent forgot to close task
IF agent finished BUT Beads task still in_progress THEN
bd close bd-g7h8 # Orchestrator closes it
END IF
END WHEN
Multi-Agent Coordination:
# When spawning multiple agents in parallel
# Example: 3 engineers working on independent features
# After spawning all agents, check status
bd list --assignee "Engineer-*" --json | jq -r '
"Active agents:",
(.[] | select(.status == "in_progress") | " \(.assignee): \(.title)"),
"",
"Progress: \([ .[] | select(.status == "closed") ] | length)/\(length) completed"
'
# Monitor for stuck agents (no recent updates)
bd show bd-g7h8 # Check last_update timestamp
# If no updates for >15 minutes, agent may be stuck
# Check work logs for detailed progress
tail -20 .ai/tasks/*/20-work-log.md
4. Conflict Resolution and Dependency Management
Responsibility: Handle conflicts and manage dependencies between tasks.
Conflict Types:
Technical Conflicts:
Example: Two subtasks modify the same code region
Resolution:
1. Identify conflict nature
2. Determine correct sequence
3. Update task dependencies
4. Coordinate timing
5. Verify integration
Resource Conflicts:
Example: Multiple agents need same resource
Resolution:
1. Prioritize tasks
2. Sequence access
3. Consider parallel alternatives
4. Coordinate timing
Requirement Conflicts:
Example: Contradictory requirements discovered
Resolution:
1. Document conflict
2. Consult user for clarification
3. Update requirements
4. Adjust affected tasks
5. Quality Assurance Oversight
Responsibility: Ensure work meets quality standards through mandatory reviews and verification.
Quality Gates:
BEFORE marking complete:
✓ All subtasks completed
✓ All tests passing
✓ Code coverage meets target
✓ Tester validation: APPROVED (MANDATORY for code changes)
✓ Reviewer validation: APPROVED (MANDATORY for code changes)
✓ All review findings addressed
✓ Documentation complete
✓ Acceptance criteria met
Quality Checks:
- Monitor test results
- Review code quality metrics
- Ensure standards compliance
- Verify documentation
- Validate against requirements
- Coordinate mandatory reviews for code changes
5.1 MANDATORY Code Quality Review Coordination
ENFORCEMENT: For all work packages involving code changes, orchestrator MUST coordinate mandatory validation by Tester and Reviewer agents. This is enforced by the Code Quality Review Gate.
Trigger Condition:
IF work package includes code changes THEN
REQUIRE Tester validation (TDD and test sufficiency)
REQUIRE Reviewer validation (code quality and standards)
BLOCK completion until both validations pass
END IF
Mandatory Review Procedure:
STEP 1: Detect code changes
code_changes = identify_modified_code_files(work_package)
IF code_changes present THEN
proceed to STEP 2
ELSE
skip review gate (documentation-only changes)
END IF
STEP 2: Delegate to Tester agent (MANDATORY)
tester = Task(
subagent_type="general-purpose",
prompt="You are the Tester role from .ai-pack/roles/tester.md.
Validate TDD compliance and test sufficiency.
Focus: TDD process, coverage (80-90%), test quality.
Report findings in .ai/tasks/${task_id}/30-review.md"
)
tester_result = wait_for_completion(tester)
IF tester_result == "CHANGES REQUIRED" THEN
coordinate_test_fixes()
resubmit_to_tester()
END IF
STEP 3: Delegate to Reviewer agent (MANDATORY)
reviewer = Task(
subagent_type="general-purpose",
prompt="You are the Reviewer role from .ai-pack/roles/reviewer.md.
Review code quality and standards compliance.
Focus: code quality, architecture, security, documentation.
Report findings in .ai/tasks/${task_id}/30-review.md"
)
reviewer_result = wait_for_completion(reviewer)
IF reviewer_result == "CHANGES REQUESTED" THEN
coordinate_code_fixes()
resubmit_to_tester() // Verify tests still pass
resubmit_to_reviewer()
END IF
STEP 4: Verify both validations passed
IF tester_approved AND reviewer_approved THEN
GATE PASSED
proceed_to_acceptance()
ELSE
GATE BLOCKED
WORK STATUS = INCOMPLETE
report_blocking_issues()
END IF
Review Orchestration Strategy:
Sequential Review (Recommended):
Execute reviews sequentially to optimize feedback cycle:
1. Tester validation FIRST
- Catches test issues early
- Ensures tests pass before code review
2. Fix test issues if found
- Worker addresses Tester findings
- Re-validate with Tester
3. Reviewer validation AFTER tests validated
- Reviewer sees code with validated tests
- More efficient review process
4. Fix code issues if found
- Worker addresses Reviewer findings
- Re-validate with Tester (tests still pass?)
- Re-validate with Reviewer
Parallel Review (Alternative):
Execute reviews in parallel for faster feedback:
Launch both in single message block:
- Task(tester, "Validate TDD and tests")
- Task(reviewer, "Review code quality")
Consolidate feedback and coordinate fixes
Use when: High confidence in test quality
Enforcement Rules:
RULE 1: Cannot skip reviews for code changes
IF code changes present AND reviews not performed THEN
GATE VIOLATION: "Code Quality Review Gate - Reviews required"
BLOCK work acceptance
END IF
RULE 2: Work incomplete if reviews fail
IF Tester verdict == "CHANGES REQUIRED" THEN
WORK INCOMPLETE
REQUIRE fixes for Critical/Major findings
END IF
IF Reviewer verdict == "CHANGES REQUESTED" THEN
WORK INCOMPLETE
REQUIRE fixes for Critical/Major findings
END IF
RULE 3: Both validations must pass
IF NOT (tester_approved AND reviewer_approved) THEN
WORK STATUS = INCOMPLETE
BLOCK acceptance
BLOCK sign-off
END IF
Blocking Conditions (Work Incomplete):
❌ From Tester:
- TDD not followed
- Coverage < 80%
- Tests failing
- Critical logic untested (<95%)
- Error handling untested (<90%)
- Integration points untested (<100%)
- Flaky tests
❌ From Reviewer:
- Security vulnerabilities
- Major standards violations
- Architecture violations
- Poor error handling
- Acceptance criteria not met
Documentation Requirements:
All review findings MUST be documented in:
.ai/tasks/${task_id}/30-review.md
Required sections:
- Tester Validation (verdict, findings, status)
- Reviewer Validation (verdict, findings, status)
- Combined Result (overall verdict, blocking issues, next steps)
Gate Compliance Verification:
BEFORE marking work complete, verify:
□ Code changes identified
□ Tester delegated and completed (if code changes)
□ Tester verdict: APPROVED
□ Reviewer delegated and completed (if code changes)
□ Reviewer verdict: APPROVED
□ All blocking issues resolved
□ 30-review.md complete
□ Ready for acceptance
IF all verified AND both approved THEN
PASS Code Quality Review Gate
ELSE
FAIL Code Quality Review Gate
WORK INCOMPLETE
END IF
5.2 Task Completion and Cleanup
CRITICAL: Task completion is a multi-step process. "Done" means agent finished work. "Done done" means work is validated and artifacts are cleaned up.
Definition of "Done Done":
Task is "DONE DONE" when ALL criteria met:
✓ Agent completed work
✓ All acceptance criteria met
✓ Tests passing (validated by Tester)
✓ Code quality approved (validated by Reviewer)
✓ Documentation artifacts created (as appropriate for task)
✓ Code committed to repository
✓ Beads task closed
✓ Task packet archived (.ai/tasks/ → .ai/tasks/.archived/)
✓ Execution artifacts cleaned up (.beads/tasks/)
Completion and Cleanup Procedure:
# STEP 1: Wait for agent to complete
agent wait $task_id
echo "✅ Agent reported completion"
# STEP 2: Validate work (MANDATORY for code changes)
# Run Tester validation
tester_task=$(bd create "Validate tests for $task_id" --priority high --json | jq -r '.id')
Task(
subagent_type="general-purpose",
prompt="You are the Tester role. Validate TDD compliance and test coverage for $task_id.",
description="Test validation for $task_id"
)
# Run Reviewer validation
reviewer_task=$(bd create "Review code for $task_id" --priority high --json | jq -r '.id')
Task(
subagent_type="general-purpose",
prompt="You are the Reviewer role. Review code quality and standards for $task_id.",
description="Code review for $task_id"
)
# Verify both approved
tester_status=$(check validation status)
reviewer_status=$(check validation status)
IF tester_status != "APPROVED" OR reviewer_status != "APPROVED" THEN
echo "❌ Validation failed - task NOT done"
# Address findings, re-validate
EXIT
END IF
echo "✅ Validation passed - proceeding to completion"
# STEP 3: Verify documentation artifacts
# Agent should have created these as part of work (task-dependent):
# - ADRs (for architectural decisions)
# - User docs (for user-facing features)
# - API docs, diagrams, etc. (as applicable)
# Verify expected artifacts exist (examples - adjust per task)
# test -f docs/architecture/decisions/ADR-XXX.md || echo "⚠️ Missing expected ADR"
# test -f docs/feature-X.md || echo "⚠️ Missing expected documentation"
# What matters: Agent created documentation appropriate for THIS task
# STEP 4: Commit all work (code + documentation)
git add -A
git commit -m "Implement feature X
- Implementation details
- Tests passing (validated by tester)
- Code reviewed (approved by reviewer)
Closes: $beads_task_id
Co-Authored-By: Agent <agent@ai-pack>"
# STEP 5: Close Beads task (keeps audit trail)
bd close $task_id --reason "Feature complete, validated, and committed"
# STEP 6: Clean up and archive (SUCCESS ONLY!)
# Only clean up on successful, validated completion
# DO NOT clean up on failure - artifacts needed for debugging
# Verify task is closed first
status=$(bd show $task_id --json | jq -r '.status')
if [ "$status" = "closed" ]; then
echo "🧹 Cleaning up and archiving artifacts..."
# 6a. Archive task packet (if exists)
task_packet_dir=$(find .ai/tasks -type d -name "*" -exec grep -l "$task_id" {}/00-contract.md \; 2>/dev/null | head -1 | xargs dirname)
if [ -n "$task_packet_dir" ] && [ -d "$task_packet_dir" ]; then
# Create archive directory if needed
mkdir -p .ai/tasks/.archived/$(date +%Y-%m)
# Move to archive
archive_dest=".ai/tasks/.archived/$(date +%Y-%m)/$(basename $task_packet_dir)"
mv "$task_packet_dir" "$archive_dest"
echo "✓ Archived task packet: $archive_dest"
fi
# 6b. Remove execution artifacts (logs, metadata, prompts)
internal_id=$(find .beads/tasks -name "00-metadata.json" -exec grep -l "$task_id" {} \; 2>/dev/null | head -1 | xargs dirname | xargs basename)
if [ -n "$internal_id" ]; then
rm -rf ".beads/tasks/$internal_id"
echo "✓ Removed execution artifacts: .beads/tasks/$internal_id"
fi
echo "✅ Cleanup complete"
else
echo "⚠️ Task not closed - skipping cleanup"
fi
# STEP 7: (Optional) Delete from Beads if truly no longer needed
# Keeps: Closed tasks for audit trail (default, recommended)
# Delete: Only for abandoned/duplicate/mistake tasks
# bd delete $task_id --force # Rare - only if task should not exist
echo "🎉 Task $task_id is DONE DONE"
When NOT to Clean Up:
# DO NOT clean up on failure
agent wait $task_id --stream
if [ $? -ne 0 ]; then
echo "❌ Agent failed - keeping artifacts for debugging"
agent logs $task_id --tail 50
# DO NOT mv .ai/tasks/...
# DO NOT rm -rf .beads/tasks/...
# DO NOT bd close (task still needs work)
exit 1
fi
# DO NOT clean up on validation failure
tester_result = validate_tests()
if tester_result != "APPROVED"; then
echo "❌ Tests inadequate - keeping artifacts"
# DO NOT mv .ai/tasks/...
# DO NOT rm -rf .beads/tasks/...
# DO NOT bd close (work incomplete)
exit 1
fi
Task Packet Archiving:
Task packets in .ai/tasks/ should be archived (not deleted) for audit trail:
Archive Structure:
.ai/
├── tasks/ # Active tasks only
│ ├── ai-pack-4mn-20260126090000-feature-x/ # Current work
│ └── ai-pack-4op-20260126090000-bug-fix/ # Current work
└── tasks/.archived/ # Completed tasks (organized by month)
├── 2026-01/
│ ├── ai-pack-4qr-20260115090000-login-impl/
│ └── ai-pack-4st-20260118090000-api-refactor/
└── 2026-02/
└── ai-pack-4uv-20260203090000-caching/
Why archive instead of delete:
✓ Maintains history of what was worked on
✓ Can reference past decisions and approaches
✓ Useful for retrospectives and learning
✓ Helps with future similar tasks
.gitignore recommendation:
# Keep archive structure in git for audit trail
.ai/tasks/.archived/**
Documentation Artifact Guidelines:
Documentation is part of the work, not part of cleanup:
✅ CORRECT: Agent creates docs during work
- Engineer implements feature
- Engineer creates appropriate documentation (examples):
* ADR if making architectural decision
* User docs if user-facing feature
* API docs if creating new endpoints
* Diagrams if complex interactions
- Engineer commits: code + docs together
- Orchestrator validates and cleans up execution logs
❌ WRONG: Orchestrator copies docs during cleanup
- Engineer implements feature
- Orchestrator extracts documentation from logs
- Orchestrator creates docs from agent output
- This means agent didn't complete the work!
Artifacts That Should Exist (created by agent):
- ADRs in
docs/architecture/decisions/ - User documentation in
docs/ - API documentation
- Diagrams, architecture docs
- README updates
Artifacts to Clean Up (transient execution data):
.beads/tasks/<internal-id>/execution.log.beads/tasks/<internal-id>/00-metadata.json.beads/tasks/<internal-id>/agent-prompt.txt.beads/tasks/<internal-id>/30-results.md(transient summary)
Beads Task States:
closed (default) - Task complete, kept for audit/history
- Use: Standard completion path
- Result: Can query with bd list --status closed
- Disk: Task data in .beads database, execution artifacts cleaned
deleted - Task removed from database (tombstone created)
- Use: Abandoned/duplicate/mistake tasks only
- Result: bd list won't show it
- Command: bd delete $task_id --force
Cleanup Verification:
# Verify task is closed
bd show $task_id | grep "Status: closed"
# Verify artifacts cleaned
ls .beads/tasks/task-* | grep -q $internal_id && echo "⚠️ Not cleaned" || echo "✓ Cleaned"
# Verify docs committed
git log --oneline -1 | grep -q $task_id && echo "✓ Committed" || echo "⚠️ Not committed"
# Verify work is complete
test -f docs/architecture/decisions/ADR-*.md && echo "✓ ADR exists"
git diff --exit-code || echo "⚠️ Uncommitted changes"
Summary:
- Agent work completes → "Done"
- Orchestrator validates (tester + reviewer) → "Validated"
- Orchestrator commits (code + docs) → "Persisted"
- Orchestrator closes Beads task → "Tracked"
- Orchestrator cleans execution artifacts → "Done Done"
