Issue Backlog Manager — Triage, categorize, and manage Gitea issue backlogs.
|
||||
|
||||
Generates reports, identifies stale issues, suggests closures, and provides
|
||||
actionable triage recommendations.
|
||||
|
||||
Usage:
|
||||
python bin/issue_backlog_manager.py timmy-home # Full report
|
||||
python bin/issue_backlog_manager.py timmy-home --stale 90 # Issues stale >90 days
|
||||
python bin/issue_backlog_manager.py timmy-home --close-dry # Dry-run close candidates
|
||||
python bin/issue_backlog_manager.py timmy-home --json # JSON output
