✅ Successfully implemented automatic issue triage workflow with AI-based labeling:

• Rewrite workflow to use actions/ai-inference@v1 instead of keyword matching
• Use actions/github-script@v7 to fetch available labels from the repository
• Pass issue context and available labels to AI for intelligent classification
• Apply AI-selected labels to issues
• Fix AI inference output handling (use steps.inference.outputs.response)
• Implement batch processing via workflow dispatch for individual issues
• Split into reusable and calling workflows following repo patterns
• Remove unused process_unlabeled input parameter
• Validate workflow syntax (actionlint and yamllint)

Implementation Summary

Split workflow structure (following wp-cli/.github patterns):

1. reusable-issue-triage.yml: Reusable workflow (NOT synced)

   • Contains all the logic for triaging issues
   • Uses workflow_call trigger
   • Has three jobs: triage-new-issue, triage-unlabeled-issues, triage-single-issue

2. issue-triage.yml: Calling workflow (synced to all repos)

   • Simple wrapper that calls the reusable workflow
   • Triggers on issues.opened and workflow_dispatch
   • Only passes issue_number input to reusable workflow
   • Gets synced to all wp-cli repositories

Workflow Logic

• When triggered by issues.opened: Runs triage-new-issue job
• When triggered by workflow_dispatch with no issue_number: Runs triage-unlabeled-issues job (finds all unlabeled issues and dispatches individual workflows)
• When triggered by workflow_dispatch with issue_number: Runs triage-single-issue job (processes specific issue)

Key Features

• AI-powered triage: Uses actions/ai-inference@v1 with custom prompts
• Dynamic label fetching: Gets available labels from each repository
• Batch processing: Dispatches individual workflows for unlabeled issues
• Single issue mode: Can triage specific issues via workflow_dispatch
• Security hardened: Issue data passed via environment variables
• Follows repo patterns: Split into reusable + calling workflows like other workflows

• Fixes Add workflow for triaging issues #166
