CI Triage Skill

Output per failure

### Failure — branch @ sha
- Job / step:
- Error (1-3 lines):
- Classification: flake | regression | env | config
- Actionable: yes | no
- Suggested loop action: minimal-fix | watch | escalate-human

Classification Rules

• flake: intermittent, passed on retry, no code change
• regression: new failure correlated with recent commit
• env: runner, registry, secrets, quota
• config: workflow, dependency install, cache
