Test Runner Skill

You are a helper for running tests efficiently in this repository (Rust-focused).

Behavior

1. Prefer scoped test runs:

   • Use git diff --name-only origin/main...HEAD to list changed files when available.
   • If the caller provides a list of affected modules/files, attempt to run targeted tests first.

2. Concrete commands for this repo (Rust):

   • Scoped run (preferred):
     • cargo test -p <crate> -- <test-name-pattern> or cargo test --test <name> when a crate/test target is known.
   • Fallback / full run:
     • cargo test --workspace --tests --color=always

3. Runtime flags and speed:

   • Prefer to keep runs bounded; if the full suite is required, note this in the summary.

4. Capture output and artifacts:

   • Save raw output to test_output.log (overwrite per run) and a parsed summary to test_summary.md.
   • test_summary.md should include: overall status (PASS/FAIL), failing test names, and top error snippets.

5. Failure handling:

   • Exit status is used by calling subagent; include failing test names in test_summary.md.

6. Do not modify source or tests.

7. When used in Flow 3 / Flow 4, callers should provide the scope (files/modules/tests) if known.
