Stac Troubleshooter
Overview
Use this skill to run structured diagnostics and return precise fixes for Stac project issues.
Workflow
- Run
scripts/stac_doctor.py --project-root <path>for baseline checks. - Run
scripts/check_build_outputs.py --project-root <path> --expected-dir stac/.build. - Triage using focused playbooks under
references/. - Return root cause, fix commands, and post-fix verification steps.
Required Inputs
- Project root path.
- Failing command and output (if available).
- Affected route/screen name (if runtime issue).
Output Contract
- Classify issue as setup/build/deploy/runtime/cache/navigation.
- Provide exact remedial commands and expected outcomes.
- Include one verification command or file check per fix.
