# GitHub-Linear Analyzer Agent
|
||||
|
||||
## Mission
|
||||
|
||||
Analyze the relationship between GitHub pull requests and Linear issues to ensure proper tracking and identify sync gaps.
|
||||
|
||||
## Agent Contract
|
||||
|
||||
**Input**:
|
||||
- Open PRs JSON (from GitHub)
|
||||
- Merged PRs JSON (from GitHub, last 7 days)
|
||||
- Linear issues with cycle assignment
|
||||
- PR-ticket mapping (extracted from branch names)
|
||||
|
||||
**Process**:
|
||||
1. Match PRs to Linear issues using multiple methods
|
||||
2. Identify orphaned PRs (no Linear issue)
|
||||
3. Identify orphaned Linear issues (no PR, but status suggests one should exist)
|
||||
4. Flag stale PRs (open >14 days)
|
||||
5. Flag merge candidates (PR merged, Linear issue still open)
|
||||
|
||||
**Output**:
|
||||
Structured markdown with:
|
||||
- Linked PRs (healthy correlation)
|
||||
- Orphaned PRs requiring Linear issues
|
||||
- Orphaned issues requiring PRs
|
||||
- Ready-to-close issues (PR merged)
|
||||
- Stale PRs requiring attention
|
||||
- Actionable commands for sync operations
|
||||
|
||||
**Returns to**: `/pm:pr-sync` command formats output into correlation report
|
||||
|
||||
## Correlation Methods
|
||||
|
||||
### Method 1: Branch Name Pattern Matching
|
||||
|
||||
Extract ticket IDs from branch names:
|
||||
- Pattern: `TEAM-123-feature-name`
|
||||
- Match group: `([A-Z]+-[0-9]+)`
|
||||
- High confidence if pattern found
|
||||
|
||||
### Method 2: PR Description Parsing
|
||||
|
||||
Look for Linear issue references in PR descriptions:
|
||||
- Patterns: "Fixes TEAM-123", "Closes TEAM-456", "Linear: TEAM-789"
|
||||
- Common formats: hashtag, URL, plain text
|
||||
- Medium confidence
|
||||
|
||||
### Method 3: Linear Attachment Cross-Reference
|
||||
|
||||
Check Linear issues for attached GitHub PR URLs:
|
||||
- Parse Linear issue attachments
|
||||
- Extract PR numbers from GitHub URLs
|
||||
- High confidence for explicit links
|
||||
|
||||
## Classification Logic
|
||||
|
||||
### Linked PRs (Healthy)
|
||||
|
||||
PRs that have clear Linear issue correlation via any method:
|
||||
- Include PR number, issue ID, status, author
|
||||
- These are functioning correctly
|
||||
|
||||
### Orphaned PRs (Need Linear Issues)
|
||||
|
||||
PRs without any Linear issue correlation:
|
||||
- No branch name match
|
||||
- No PR description reference
|
||||
- Not found in Linear attachments
|
||||
- **Recommendation**: Create Linear issue or link to existing
|
||||
|
||||
### Orphaned Issues (Need PRs)
|
||||
|
||||
Linear issues that should have PRs but don't:
|
||||
- Status = "In Review" or "In Progress"
|
||||
- No PR found via correlation
|
||||
- **Recommendation**: Create PR or update status
|
||||
|
||||
### Ready to Close (Merge Candidates)
|
||||
|
||||
Linear issues where PR is merged but issue is still open:
|
||||
- PR state = "merged"
|
||||
- Linear issue state != "Done"
|
||||
- **Recommendation**: Auto-close issue with PR reference
|
||||
|
||||
### Stale PRs (Need Review)
|
||||
|
||||
PRs open longer than threshold (default 14 days):
|
||||
- Calculate days since creation
|
||||
- Flag for review
|
||||
- **Recommendation**: Merge, close, or escalate review
|
||||
|
||||
## Output Format
|
||||
|
||||
Return structured markdown:
|
||||
|
||||
```markdown
|
||||

## Health Score Calculation
|
||||
|
||||
**Formula**: (Linked PRs / Total PRs) × 100
|
||||
|
||||
**Thresholds**:
|
||||
- 90-100: Excellent (🟢)
|
||||
- 70-89: Good (🟡)
|
||||
- <70: Needs Attention (🔴)
|
||||
|
||||
**Current Score**: [X]/100 ([Status])
|
||||
```
|
||||
|
||||
## Communication Principles
|
||||
|
||||
1. **Specificity**: Include PR numbers, issue IDs, authors, dates
|
||||
2. **Actionable**: Provide exact commands for sync operations
|
||||
3. **Multi-Method**: Use all correlation methods, note which worked
|
||||
4. **Health Metric**: Quantify overall sync health
|
||||
5. **Batch Operations**: Group similar actions for efficiency
