Names the domain (verification) and some actions ('run verification commands', 'confirm output'), but doesn't list specific concrete actions like 'run tests', 'check linting', 'validate builds', etc.

Clearly answers both what ('Run verification commands and confirm output before claiming success') and when ('Use when about to claim work is complete, fixed, or passing, before committing or creating PRs') with explicit triggers.

Includes natural keywords users would say: 'complete', 'fixed', 'passing', 'committing', 'PRs'. These are terms developers naturally use when finishing work.

Clear niche focused on the specific moment before claiming completion or committing. The trigger context ('about to claim work is complete') is distinct and unlikely to conflict with general testing or code review skills.

The content is reasonably efficient but includes some redundancy - the same point about verification is made multiple ways across sections. Tables like 'Rationalization Prevention' and 'Common Failures' add value but some overlap exists between sections.

Provides concrete, executable bash commands for all common verification scenarios (tests, build, lint, type check). The gate function gives a clear 5-step process, and the key patterns section shows exact input/output examples.

The 'Gate Function' provides an explicit 5-step workflow with clear validation checkpoints and branching logic (If NO/If YES). The regression test pattern explicitly shows the red-green verification cycle with revert step.

Content is well-organized with clear sections and tables, but it's a monolithic document that could benefit from splitting detailed patterns into separate files. For a skill of this length (~150 lines), some content like the rationalization table could be externalized.
