feat: Add autonomous PR comment resolution with AI confidence scoring

[iamladi]

Summary

Adds /address-pr-comments command with dual-mode operation (interactive and autonomous) powered by AI confidence scoring for intelligent PR comment prioritization and resolution.

Key Features

🤖 Dual-Mode Operation

Interactive Mode (Terminal)

• User selects which comments to address
• Shows all comments with confidence scores
• Verbose explanations and diffs
• Default when run in terminal

Autonomous Mode (CI/CD)

• Auto-detects CI/CD environment
• Filters high-confidence comments (score ≥ 80)
• Auto-addresses safe changes without user input
• Creates rollback safety checkpoint
• Detailed reporting with reasoning

🎯 AI-Powered Confidence Scoring (0-100)

Based on 2024 AI code review research, comments are scored using:

1. Specificity (30pts): File path + line number + concrete suggestions
2. Language Clarity (25pts): Directive ("must", "please") vs suggestive ("consider")
3. Category Confidence (25pts): STYLE (25) > DOCS (20) > CODE (15) > TEST (10)
4. Reviewer Authority (10pts): Maintainer/owner (10) > contributor (3)
5. Discussion Status (10pts): Blocking (10) > unresolved (7)

Thresholds:

• 80-100 (High): Auto-addressed in autonomous mode
• 60-79 (Medium): Presented in interactive mode
• 0-59 (Low): Skipped, flagged for manual review

🔒 Safety Mechanisms

• Rollback capability: Git stash created before autonomous changes
• No auto-commits: User maintains control
• Skip low-confidence: Ambiguous comments flagged for review
• Detailed reporting: Shows what was/wasn't addressed with reasoning

🚀 Auto-Detection

Automatically detects CI/CD environments:

• CI, GITHUB_ACTIONS, JENKINS_URL, GITLAB_CI
• CIRCLECI, TRAVIS
• Non-TTY stdin (piped input)

Manual override available:

/address-pr-comments 123 --autonomous  # Force autonomous
/address-pr-comments 123 --interactive # Force interactive

Research Foundation

Based on 2024 industry research:

• 40-73.8% comment resolution rates achievable with AI
• Confidence scoring reduces noise (26.2% false positives filtered)
• Prioritization by impact improves developer focus
• Safety mechanisms prevent over-reliance on automation

Usage Examples

Interactive Mode

$ /address-pr-comments 42

Found 3 comments on PR #42: Add user authentication

Autonomous Mode (CI/CD)

$ /address-pr-comments 42 --auto

🤖 AUTONOMOUS MODE ACTIVE
Analyzing 5 comments, threshold: 80/100

High-Confidence (2 addressed):
✓ [STYLE] src/utils.ts:42 (95)
✓ [CODE] src/auth.ts:25 (90)

Skipped (3):
⏭️ [CODE] src/api.ts:55 (65) - Vague suggestion
⏭️ [TEST] tests/auth.test.ts (45) - Question without action
⏭️ [QUESTIONS] src/models.ts (35) - Ambiguous feedback

🔄 Rollback: git stash apply stash^{/pre-autonomous-pr-42-...}
📊 Summary: 2 addressed, 3 skipped

Testing

✅ Plugin validation passed: bun run validate
✅ Follows 2024 AI code review best practices
✅ Safety mechanisms tested (rollback, skip low-confidence)
✅ Environment detection logic validated

Benefits

• Saves time: Auto-addresses high-confidence comments in CI/CD
• Reduces noise: Filters low-confidence and ambiguous feedback
• Safe: Rollback capability and no auto-commits
• Intelligent: AI scoring prioritizes important feedback
• Flexible: Works interactively or autonomously

Next Steps

After merge:

1. Plugin available at v1.2.0
2. Users can leverage autonomous mode in CI/CD pipelines
3. Interactive mode remains default for terminal usage
