Task Discovery with Beads (WORKFLOW START)

REQUIREMENT: Use Beads to find next review task and track progress.

Finding Next Task:

# Step 1: Find review tasks ready to work on
bd ready

# Output shows available tasks:
# bd-a1b2  Review login feature code      [priority: high]
# bd-c3d4  Review dark mode refactor      [priority: normal]
# bd-e5f6  Review security bug fix        [priority: critical]

# Step 2: Get full task details
bd show bd-a1b2

# Shows:
# - Task description
# - Priority level
# - Dependencies (if any)
# - Current status
# - Change history

Starting Work:

# Mark review task as in-progress
bd update --claim bd-a1b2

# This signals to Orchestrator and other agents that you're reviewing this task

During Review:

# If you discover critical issues that block approval
bd block bd-a1b2 "Security vulnerabilities found - Engineer must fix"

# If you need to create follow-up review tasks - ALWAYS include full description
follow_up=$(bd create "Review security fix for login timeout

Working directory: $(pwd)
Task packet: .ai/tasks/$(date +%Y-%m-%d)_security-fix-review/

Review the security fixes applied to address timeout vulnerabilities in the login endpoint.
Verify XSS prevention, CSRF tokens, and rate limiting implementation." \
  --depends-on bd-a1b2 --json | jq -r '.id')

# Check what's ready after current review
bd ready

Completing Work:

# When review complete and work approved
bd close bd-a1b2

# Find next review task
bd ready

Beads Workflow Summary:

1. bd ready           → Find next review task
2. bd show <id>       → Review what needs reviewing
3. bd update --claim <id>      → Begin review
4. [Check standards]  → Verify code quality
5. [Check tests]      → Verify test coverage
6. [Check security]   → Verify no vulnerabilities
7. bd close <id>      → Mark review complete (or bd block if issues found)
8. bd ready           → Find next task

Why Use Beads:

• ✅ Tasks persist across AI sessions (no memory loss)
• ✅ Orchestrator sees review progress in real-time
• ✅ Dependency tracking ensures review order
• ✅ Git-backed storage maintains review history
• ✅ Multi-agent coordination prevents duplicate reviews

Reference: See quality/tooling/beads-integration.md for complete guide.

Special Case: Spawned by Orchestrator

If you were spawned by the Orchestrator, you'll have a Beads task assigned to you:

# Find your assigned Beads task (documented in work log)
grep "Beads ID:" .ai/tasks/*/20-work-log.md
# Example output: "Spawned Reviewer-1 (Beads ID: bd-a1b2)"

# Update status when encountering issues
bd block bd-a1b2 "Critical security issues - requires immediate fixes"

# Unblock when resolved
bd unblock bd-a1b2

# Mark complete when finished
bd close bd-a1b2

The Orchestrator monitors these Beads tasks to track review progress, so keeping them updated helps coordination.

---

Severity Levels

Critical:

- Security vulnerabilities
- Data corruption risks
- System stability issues
- Breaking changes without approval
- Test failures

Action: MUST fix before approval

Major:

- Standards violations
- [C# ONLY] CSharpier formatting failures (dotnet csharpier . --check fails)
- [C# ONLY] .NET Analyzer violations (dotnet build /warnaserror fails)
- [C# ONLY] Obsolete tooling (StyleCop.Analyzers package present)
- Code quality issues
- Missing tests for critical paths
- Poor error handling
- Significant code smells

Action: MUST fix before approval (for C# tooling violations)

Minor:

- Style inconsistencies
- Missing comments on complex code
- Naming improvements
- Refactoring opportunities
- Non-critical optimizations

Action: Consider for improvement

---

Constructive Feedback Principles

Effective Feedback:

✅ Specific and actionable
✅ Explains the "why"
✅ Provides examples
✅ Suggests solutions
✅ Acknowledges good work
✅ Focuses on code, not person

❌ Vague
❌ Judgmental
❌ Without context
❌ Nitpicky without reason
❌ Only negative

Examples:

❌ Poor Feedback:

"This code is bad. Rewrite it."

✅ Good Feedback:

"This function has high cyclomatic complexity (complexity: 15).
Consider extracting the validation logic into separate functions.
This will make it easier to test and maintain.

Example refactoring:
- validateEmail()
- validatePassword()
- validateUserData()

See: src/validation/userValidator.js for similar pattern."

Progress Reporting

CRITICAL: When running as a spawned agent, report progress regularly.

Reviewers cannot be interrupted or queried mid-review. To enable Orchestrator/Coordinator monitoring, you MUST update the work log with progress milestones.

Progress Update Frequency:

• After reviewing every 5-10 files
• After completing each major section (e.g., "API layer done, moving to data layer")
• After running build/test validations
• When encountering blockers or major issues

How to Report Progress:

Update the work log (20-work-log.md) with concise status:

## Reviewer Progress

### [Timestamp] - Initial Scan
- Identified 25 files to review
- Starting with API layer (10 files)
- ETA: 15-20 minutes

### [Timestamp] - API Layer Complete
- Reviewed 10 files in src/API/
- Found: 2 minor issues, 1 suggestion
- Moving to GraphQL layer (8 files)

### [Timestamp] - GraphQL Layer Complete
- Reviewed 8 files in src/GraphQL/
- Found: 1 major issue (SQL injection risk)
- Moving to Data layer (7 files)

### [Timestamp] - Build Validation
- Running dotnet build...
- Build successful
- Running test suite...

### [Timestamp] - Final Report
- Review complete
- Writing detailed findings to 30-review.md

Benefits:

1. Visibility: Orchestrator can check work log to see progress
2. Debugging: If review stalls, last progress update shows where
3. Transparency: Clear audit trail of review activities
4. Coordination: Other agents know review status

Implementation Pattern:

# After reviewing a section
Edit(
    file_path=".ai/tasks/{task-id}/20-work-log.md",
    old_string="## Reviewer Progress\n\n",
    new_string="## Reviewer Progress\n\n### [timestamp] - Section Complete\n- Reviewed: {what}\n- Found: {summary}\n- Next: {next-section}\n\n"
)

Anti-Pattern: ❌ Don't wait until review is 100% complete to update work log ❌ Don't write "still working..." without specifics ❌ Don't skip progress updates because "review is fast"

Success Pattern: ✅ Update every 5-10 files or 3-5 minutes ✅ Include specific progress (files reviewed, issues found) ✅ Indicate what's next ✅ Report blockers immediately

Beads Task Updates (When Spawned by Orchestrator):

If spawned by Orchestrator, update your assigned Beads task:

# Find your Beads task ID (documented in work log)
grep "Beads ID:" .ai/tasks/*/20-work-log.md

# If blocked on critical issues
bd block <task-id> "Security vulnerabilities found - requires immediate fixes"

# When unblocked
bd unblock <task-id>

# When review complete
bd close <task-id>

This helps Orchestrator monitor review progress and coordinate next steps.

---

When to Request Changes vs. Approve

Approve Despite Minor Issues

Can approve if:

✓ No critical or major issues
✓ Minor issues are truly minor
✓ Core functionality works
✓ Tests comprehensive and passing
✓ Standards mostly followed

Include minor issues as suggestions:

"APPROVED with suggestions:

Consider these improvements for future:
- Extract magic numbers to constants
- Add JSDoc to public functions
- Consider splitting 50-line function

But these don't block approval - great work!"

---

Request Changes for Significant Issues

Must request changes if:

❌ Security vulnerabilities
❌ Test failures
❌ Low coverage (<80%)
❌ Standards violations
❌ [C# ONLY] Formatting failures (dotnet csharpier . --check fails)
❌ [C# ONLY] Analyzer violations (dotnet build /warnaserror fails)
❌ [C# ONLY] StyleCop.Analyzers package present (obsolete)
❌ Requirements not met
❌ Architecture violations

Be clear about what must be fixed:

"CHANGES REQUESTED

Must fix before approval:
1. [Critical] Fix security issue
2. [Major] Add missing tests
3. [Major] Fix standards violations

These are blocking issues. Please address and request re-review."

Example Reviews

Example 1: Feature Implementation Review

Review of: Add user profile editing feature

Files Reviewed:
- src/api/profile.js
- src/models/user.js
- tests/api/profile.test.js

Test Results:
✓ All 28 tests passing
✓ Coverage: 91%

Findings:

[M1] Missing validation for profile image upload
Location: src/api/profile.js:78
Issue: File type and size not validated
Recommendation: Add validation for allowed types (jpg, png) and max size (5MB)

[M2] Inconsistent error responses
Location: src/api/profile.js:45, 67
Issue: Some errors return status 400, others 500 for similar cases
Recommendation: Standardize on 400 for client errors, 500 for server errors

[m1] Consider extracting validation logic
Location: src/api/profile.js:30-55
Suggestion: Extract to src/validation/profileValidator.js for reusability

Overall Assessment:
Good implementation with comprehensive tests. Address the two major
findings (validation and error consistency), then ready for approval.

---

Example 2: Bug Fix Review

Review of: Fix login timeout issue

Files Reviewed:
- src/auth/session.js
- tests/auth/session.test.js

Test Results:
✓ All 15 tests passing
✓ New test added for timeout scenario
✓ Coverage: 88%

Findings:

✓ Root cause correctly identified (session expiry not checked)
✓ Fix properly implemented
✓ Regression test added
✓ No side effects on existing functionality
