The body is lean, avoids explaining concepts Claude already knows, and each step carries concrete instruction; the single intro line adds useful context (DevTools codebase, bug-link format) without padding.

It provides concrete, copy-paste-ready commands such as 'npm run test path/to/foo.test.ts:test_name', '--repeat=20', branch naming 'fixed-<bugid>', and explicit search patterns like 'it.skip(\'[crbug.com/<bugid>] ...\')', which are fully executable.

A clearly numbered sequence with explicit validation checkpoints ('Re-run the test to ensure the fix is correct', 'Verify Full Build') and a fix→retry loop for the batch un-skipping step, satisfying the explicit-validation anchor.

At under 50 lines for a single task with no bundle files, the well-organized Workflow section with numbered steps meets the simple-skill bar for progressive disclosure without needing external references.

The phrase 'unskipping a test that was previously skipped' names the domain and a single concrete action, but it does not enumerate multiple specific actions, so it stops at the 'names domain and some actions' anchor rather than the multi-action level.

The explicit 'Use this skill when unskipping a test that was previously skipped' answers both what (unskipping a previously skipped test) and when (an explicit trigger clause), matching the both-what-and-when anchor.

'unskipping a test' is a natural phrase a user might say, but common variations like '.skip', 'skipped describe', or 'disabled test' are absent, leaving coverage partial.

The narrow focus on previously-skipped tests gives it a clear niche with a distinct trigger unlikely to fire for unrelated skills.
