When to Use This Skill

Auto-invoke this skill when the conversation involves:

• Triaging new or existing issues
• Detecting duplicate issues
• Classifying issue type and priority
• Mapping issue relationships (parent, blocking, related)
• Validating issue claims against codebase
• Organizing issues into milestones or sprints
• Generating triage reports or summaries
• Keywords: "triage", "duplicate", "classify issue", "issue relationships", "blocked by", "related to"

Your Capabilities

1. Issue Triage: Review, classify, and prioritize incoming issues
2. Duplicate Detection: Find similar issues using keyword and fuzzy matching
3. Relationship Mapping: Identify parent/child, blocking, and related issues
4. Validation: Verify issue claims by checking codebase
5. Classification: Apply appropriate labels based on content analysis
6. Report Generation: Create triage summaries with recommendations

Your Expertise

1. Issue Triage Process

Standard triage workflow:

1. Initial review: Understand the issue
2. Classify: Assign type (bug, feature, etc.)
3. Prioritize: Assess urgency and impact
4. Check duplicates: Search for similar issues
5. Map relationships: Identify dependencies
6. Label: Apply appropriate labels
7. Assign: Route to appropriate team member
8. Add to board: Include in project tracking

2. Duplicate Detection

Detection strategies:

Keyword matching:

# Search for similar issues
gh issue list --search "authentication error" --json number,title,body

# Find by label
gh issue list --label "bug" --search "login fail"

Fuzzy matching: Use TF-IDF similarity scoring

{baseDir}/scripts/duplicate-detection.sh find-duplicates --issue 42

Common duplicate patterns:

• Same error message
• Same feature request
• Similar symptoms, different descriptions
• Related root cause

3. Issue Relationships

Relationship types:

Blocks: Issue A must be completed before Issue B

Issue #42: Implement authentication
Blocks: #43, #45, #47

Depends on: Issue B requires Issue A to be completed first

Issue #43: Add user profile
Depends on: #42 (authentication)

Related: Issues share context but no direct dependency

Issue #44: Add avatar upload
Related: #43 (user profile), #50 (file storage)

Duplicate: Same issue, mark one as duplicate

Issue #46: Login not working
Duplicate of: #42

Relationship mapping:

# Map relationships
{baseDir}/scripts/relationship-mapper.sh map-issue 42

# Find blocking issues
{baseDir}/scripts/relationship-mapper.sh find-blockers

# Generate dependency graph
{baseDir}/scripts/relationship-mapper.sh generate-graph

4. Issue Classification

By type:

• Bug: Something is broken
• Feature: New functionality request
• Enhancement: Improvement to existing feature
• Question: Needs clarification
• Documentation: Docs improvement

By priority (based on impact + urgency):

• Critical: System down, data loss, security issue
• High: Major functionality broken, affects many users
• Medium: Important but workaround exists
• Low: Minor issue, nice to have

Priority matrix:

                High Impact    Low Impact
High Urgency    Critical      High
Low Urgency     High          Medium/Low

By scope:

• Frontend, Backend, Database, Infrastructure, Documentation

By effort (T-shirt sizing):

• XS: < 2 hours
• S: 2-8 hours
• M: 1-3 days
• L: 3-7 days
• XL: > 1 week

5. Issue Quality

Good issue checklist:

• ✅ Clear, descriptive title
• ✅ Detailed description
• ✅ Steps to reproduce (for bugs)
• ✅ Expected vs actual behavior
• ✅ Environment details
• ✅ Screenshots/logs if applicable
• ✅ Appropriate labels
• ✅ Linked to related issues

Poor issue example:

Title: "It's broken"
Body: "doesn't work"

Good issue example:

Title: "Authentication fails with OAuth provider timeout"

Description:
When attempting to log in with Google OAuth, the authentication
fails after 30 seconds with a timeout error.

Steps to Reproduce:
1. Click "Login with Google"
2. Enter credentials
3. Wait for redirect
4. Error appears after 30 seconds

Expected: Successful authentication and redirect to dashboard
Actual: Timeout error "OAuth provider did not respond"

Environment:
- Browser: Chrome 120
- OS: macOS 14.1
- Application version: v2.3.1

Logs:
[OAuth] Timeout waiting for provider response (30000ms)

Related: #142 (OAuth integration)

6. Automated Triage Rules

Auto-label rules:

# By keywords
- body contains "error", "bug", "broken" → label: bug
- body contains "feature", "add", "new" → label: feature
- title contains "[Security]" → label: security, priority:critical

# By template
- uses bug_report template → label: bug, needs-triage
- uses feature_request template → label: feature, needs-triage

# By file paths (in PRs)
- changes frontend/* → label: scope:frontend
- changes backend/* → label: scope:backend

Your Capabilities

1. Comprehensive Issue Triage

Perform complete triage on issues:

Single issue triage:

User: "Triage issue #42"

You:
Analyzing issue #42: "Login fails with 500 error"

**Classification**:
- Type: bug ✅
- Priority: high (authentication broken)
- Scope: backend (server error)
- Effort: S (likely configuration issue)

**Duplicate check**:
Searching similar issues...
- Issue #38: "Auth server error" (80% similar) - possibly related
- Issue #27: "Login timeout" (60% similar) - different root cause

Not a duplicate, but related to #38.

**Quality check**:
✅ Clear title
✅ Has reproduction steps
❌ Missing environment details
⚠️ Could use logs/screenshots

**Recommendations**:
1. Add labels: bug, priority:high, scope:backend
2. Add comment requesting server logs
3. Link to related issue #38
4. Assign to @backend-team
5. Add to "Bug Triage" board

Apply these recommendations? [y/n]

2. Duplicate Detection

Find and merge duplicate issues:

Find duplicates:

User: "Check if #42 is a duplicate"

You:
Searching for duplicates of #42: "Authentication error"...

**Potential duplicates found**:

1. Issue #38: "Auth fails with 401" (95% match) ⚠️ HIGH
   - Same error code
   - Same component (authentication)
   - Same symptoms
   - Created 3 days earlier
   - Already has investigation in progress

   **Recommendation**: Mark #42 as duplicate of #38

2. Issue #27: "Login timeout" (65% match)
   - Similar area (login)
   - Different error (timeout vs 401)
   - Likely different root cause

   **Recommendation**: Link as related, not duplicate

**Action**:
```bash
gh issue close 42 --reason "duplicate" --comment "Duplicate of #38"
gh issue comment 38 --body "Also reported in #42"

Execute? [y/n]

### 3. Relationship Mapping

Map dependencies between issues:

**Create relationship map**:
```markdown
User: "Show relationships for issue #42"

You:
Mapping relationships for #42: "Implement JWT authentication"

**Dependencies** (blocks this issue):
None - can start immediately ✅

**Blocks** (this issue blocks):
- #43: Add user profile (needs auth first)
- #45: Implement password reset (needs auth system)
- #47: Add OAuth providers (extends auth)

**Related**:
- #38: Auth error (bug to fix in implementation)
- #50: Session management (complementary feature)

**Duplicate tracking**:
- #46: "Need login system" (duplicate, closed)

**Dependency graph**:

[#42 JWT Auth]
      ↓
┌─────┼─────┐
↓     ↓     ↓

[#43] [#45] [#47] Profile Reset OAuth

Related: #38 (bug), #50 (session)

**Impact analysis**:
- Completing #42 unblocks 3 issues
- High priority due to blocking nature
- Estimated effort: L (5-7 days)

Common Use Cases

Use Case 1: Daily Triage

User: "Triage today's new issues"

You:
Found 5 new issues created today:

**Issue #42**: bug, priority:high, assigned to @backend-team ✅
**Issue #43**: feature, priority:medium, added to backlog ✅
**Issue #44**: duplicate of #38, closed ✅
**Issue #45**: needs-more-info, commented ⏳
**Issue #46**: documentation, priority:low ✅

Summary: 4 triaged, 1 awaiting info

Use Case 2: Find Duplicates

User: "Find all duplicate issues"

You:
Scanning 156 open issues...

Found 8 potential duplicate groups:

**Group 1**: Authentication errors (3 issues)
- #42, #46, #51 (95% similarity)
- Recommend: Keep #42 (oldest), close others

**Group 2**: Dark mode requests (2 issues)
- #43, #49 (90% similarity)
- Recommend: Keep #43 (more detailed), close #49

Close all duplicates? [y/n]

Use Case 3: Dependency Analysis

User: "What can we work on next?"

You:
Analyzing issue dependencies...

**Ready to start** (no blockers):
- #42: JWT authentication (priority:high, 5d effort)
- #50: Session management (priority:medium, 3d effort)
- #52: Update docs (priority:low, 1d effort)

**Blocked** (waiting on dependencies):
- #43: User profile (blocked by #42)
- #45: Password reset (blocked by #42)

**Recommended order**:
1. #42 (unblocks 2 other issues)
2. #50 (parallel with #42)
3. #43, #45 (after #42 completes)

Important Notes

• Triage promptly: New issues should be triaged within 24 hours
• Be thorough: Check duplicates carefully before closing
• Be respectful: Always thank reporters, even for duplicates
• Document decisions: Explain why issues are closed/labeled
• Track relationships: Dependencies matter for planning
• Quality over speed: Better to triage well than triage fast

Error Handling

Common issues:

• Issue not found → Check issue number
• Permission denied → Need triage access
• Duplicate false positive → Review similarity criteria
• Missing information → Request politely
