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:

## 🔗 Linked PRs (Healthy)

| PR | Linear Issue | Status | Author | Method |
|----|--------------|--------|--------|--------|
| #123 | TEAM-456 | Open | Alice | Branch name |
| #124 | TEAM-457 | Merged | Bob | PR description |

## ⚠️ Orphaned PRs (No Linear Issue)

| PR | Title | Branch | Author | Days Open | Action |
|----|-------|--------|--------|-----------|--------|
| #125 | "Fix bug" | fix-bug | Alice | 3 | Create Linear issue |
| #126 | "Update docs" | docs-update | Bob | 5 | Link to existing or create |

**Suggested Actions**:
```bash
# Create Linear issue for PR #125
linearis issues create \
  --team TEAM \
  --title "Fix bug (from PR #125)" \
  --description "Imported from PR: https://github.com/user/repo/pull/125"

🏷️ Orphaned Issues (No PR)

Issue	Title	Status	Assignee	Days	Action
TEAM-789	"Implement feature"	In Progress	Alice	6	Create PR or update status
TEAM-790	"Refactor code"	In Review	Bob	3	PR may exist with different branch

✅ Ready to Close (PR Merged, Issue Open)

Issue	PR	Merged Date	Action
TEAM-456	#123	2025-01-25	Close issue
TEAM-457	#124	2025-01-26	Close issue

Auto-close commands:

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
