Project Platform Diagnose
Read AGENTS.md first. This is a diagnostic overlay, not a standalone workflow.
Use alongside the repo's implementation skill when debugging environment-sensitive
issues.
When to use
The problem involves build/install failures, runtime environment issues, platform integration, or headless/container behavior.
Not for
Logic bugs in repo-owned code (use the implementation skill directly), vendored dependency issues (use project-vendor-boundary), or config behavior (use project-config-and-tests).
Rules
- separate build/install failures from runtime failures
- separate environment limits from app regressions
- prefer built-in diagnostics and reproducible smoke checks before guessing
- treat headless/container failures carefully when the feature expects a richer desktop or service environment
