Issue Triage Skill

Efficiently triage GitHub issues for Java projects with categorization and prioritization.

When to Use

• User says "triage issues" / "check recent issues"
• Regular maintenance workflow
• After vacation/break (backlog processing)
• Weekly/monthly issue review

Prerequisites

Recommended: GitHub MCP server configured for optimal token usage

claude mcp add github --transport http \
  https://api.githubcopilot.com/mcp/

Alternative: Use gh CLI (less token-efficient)

Workflow

1. Fetch Issues

With GitHub MCP (recommended):

Tool: list_issues
Parameters: {
  "state": "open",
  "sort": "updated", 
  "per_page": 10
}

With gh CLI:

gh issue list --state open --limit 10 --json number,title,labels,body,url

2. Categorize Each Issue

Analyze issue content and assign category:

Bug Report ✅

Indicators:

• Has stack trace or error message
• Steps to reproduce provided
• Expected vs actual behavior described
• Mentions specific version numbers

Actions:

• Label: bug
• Verify reproducibility from description
• Check for duplicate bugs
• Add to milestone if critical

Example:

Issue #234: "NPE when loading plugin from directory"
- Stack trace: ✅
- Reproduction steps: ✅
- Version info: ✅
→ Label: bug, high-priority

Feature Request 💡

Indicators:

• Asks for new functionality
• Use case described
• "It would be nice if..." / "Could you add..."
• Rationale provided

Actions:

• Label: enhancement
• Assess alignment with project goals
• Mark for discussion if non-trivial
• Ask for community feedback

Question/Support ❓

Indicators:

• "How do I..." / "Can someone help..."
• Configuration/usage questions
• Not a bug or feature request

Actions:

• Label: question
• Provide answer or link to docs
• Suggest StackOverflow for complex help
• Close after answer if resolved

Duplicate 🔄

Search for similar issues:

• Use GitHub search: is:issue <keywords>
• Check recently closed issues
• Look for same error messages

Actions:

• Link to original: "Duplicate of #123"
• Close with polite comment
• Ask reporter to comment on original if they have additional info

Invalid/Unclear ⚠️

Indicators:

• Missing critical information
• Off-topic or spam
• Not enough context to proceed

Actions:

• Request clarification with template
• Set "needs-more-info" label
• Auto-close if no response after 14 days

3. Priority Assessment

Critical (P0) 🔴

Criteria:

• Security vulnerability
• Data loss/corruption risk
• Complete functionality breakdown
• Affects production systems

Actions:

• Label: critical
• Notify maintainers immediately
• Add to current milestone
• Consider hotfix release

Examples:

- "SQL injection vulnerability in plugin loader"
- "All plugins fail to load after upgrade"
- "ClassLoader leak causes OutOfMemoryError"

High (P1) 🟠

Criteria:

• Core feature broken
• Affects many users
• Workaround exists but painful
• Regression from previous version

Actions:

• Label: high-priority
• Add to next milestone
• Include in release notes

Examples:

- "Plugin dependencies not resolved correctly"
- "Hot reload crashes application"

Medium (P2) 🟡

Criteria:

• Edge case bug
• Enhancement with clear value
• Documentation gap
• Affects some users occasionally

Actions:

• Label: medium-priority
• Consider for future milestone
• Good for contributors

Examples:

- "Improve error message for invalid plugin"
- "Add plugin lifecycle listener"

Low (P3) 🟢

Criteria:

• Nice-to-have feature
• Cosmetic issues
• Very rare edge case
• Documentation improvements

Actions:

• Label: low-priority
• "Contributions welcome" tag
• Backlog for future

Examples:

- "Add more examples to README"
- "Typo in JavaDoc"

4. Response Templates

Need More Information

Thanks for reporting this issue! 

To investigate further, could you provide:
- Java version (java -version)
- Library version
- Minimal reproducible example
- Full stack trace (if applicable)
- Configuration files (if relevant)

This will help us diagnose and fix the issue faster.

Duplicate

Thanks for reporting! This is being tracked in #123.

Closing as duplicate. Feel free to add any additional context 
or information to the original issue.

Won't Fix (with rationale)

Thank you for the suggestion. After consideration, this doesn't 
align with the project's current direction because [reason].

Consider [alternative approach] instead, which might better 
serve your use case.

If you feel strongly about this, please open a discussion in 
our [forum/discussions] to gather community feedback.

- Ubuntu 22.04

Feature Request - Under Consideration

Interesting idea! This aligns with our goal of [project goal].

I've labeled this as 'enhancement' for further discussion.
Community feedback welcome - upvote with 👍 if you'd find 
this useful.

Token Optimization Strategies

Batch Processing

# Process multiple issues in one prompt
"Triage issues #234-243, categorize and prioritize"

Savings: ~60% fewer tokens vs one-by-one

Use Structured GitHub MCP Calls

• One call to list issues → cache results
• Targeted calls for details only when needed
• Batch label updates

Savings: ~40% fewer tokens vs repeated bash calls

Cache Issue List

# First prompt
"Fetch the last 20 issues, save list in memory"

# Subsequent prompts
"Analyze issue #5 from cached list"
"Mark #7-#9 as duplicate"

Focus on First Post + Recent Comments

• Don't read entire 50-comment threads
• Skim first post for context
• Check last 2-3 comments for updates

Anti-patterns

❌ Avoid:

# One-by-one processing
"Check issue #234"
"Now check issue #235"
"Now check issue #236"
→ Wastes tokens on repeated context loading

# Over-analyzing
Reading entire 100-comment thread
Checking all related PRs
Deep diving into code for each issue
→ Diminishing returns after certain point

# Premature closing
Closing issues without proper investigation
Missing duplicates due to poor search
→ Frustrates users, creates duplicate work

✅ Prefer:

# Batch operations
"Triage issues #234-250, categorize, prioritize"

# Quick triage decisions
Fast categorization → Can revisit if needed
Surface-level analysis for most issues
Deep dive only for critical/complex ones

# Thorough duplicate search
Quick keyword search before marking duplicate
Link to specific comment if clarification exists

Automation Opportunities

Auto-close stale issues

# Issues with no activity for 90 days and "needs-more-info" label
"Find stale issues (>90 days, needs-more-info label), 
suggest closing with polite message"

Label by keywords

# Auto-label based on content
"java.lang.NullPointerException" → bug
"add support for" → enhancement
"how do I" → question

Weekly summary

# Generate triage summary
"Summarize issues from last week:
- New bugs: X
- Feature requests: Y
- Questions: Z
- Closed: W"

Integration with GitHub

With GitHub MCP

// Structured workflow
1. list_issues → get open issues
2. get_issue → details for each
3. add_labels → categorize
4. create_comment → respond
5. close_issue → if needed

With gh CLI

# List issues
gh issue list --json number,title,labels,body

# View specific issue
gh issue view 234

# Add labels
gh issue edit 234 --add-label "bug,high-priority"

# Comment
gh issue comment 234 --body "Thanks for reporting..."

# Close
gh issue close 234 --comment "Fixed in v2.1"

Metrics to Track

After each triage session, report:

📊 Triage Summary
─────────────────
Issues processed: 15
├─ Bugs: 5 (2 critical, 3 high)
├─ Enhancements: 4
├─ Questions: 3
├─ Duplicates: 2
└─ Invalid: 1

Actions taken:
├─ Labeled: 15
├─ Responded: 12
├─ Closed: 3
└─ Milestoned: 5

Time saved: ~45 minutes (vs manual)
Token usage: 3,200 tokens

Best Practices

1. Regular cadence - Weekly triage prevents backlog
2. Be respectful - Users took time to report
3. Link resources - Docs, related issues, examples
4. Ask questions - Better to clarify than assume
5. Welcome contributions - Encourage community involvement
6. Track patterns - Common issues suggest documentation gaps
7. Celebrate reporters - Thank users for good bug reports
8. Close decisively - Don't let issues linger indefinitely

Example Workflow

# Monday morning triage
claude code ~/projects/pf4j

> view .claude/skills/issue-triage/SKILL.md
> "Triage the last 15 issues from pf4j/pf4j,
   categorize, prioritize and suggest responses"

[Claude analyzes and presents summary]

> "Apply labels and post the suggested responses"

[Claude executes actions]

> "Generate summary for release notes"

Result: 15 issues triaged in ~10 minutes vs ~45 minutes manual
