Names the domain (verification before claims) and some actions ('running verification commands', 'confirming output'), but doesn't list specific concrete actions like 'run tests', 'check linting', 'verify build succeeds'.

Clearly answers both what ('running verification commands and confirming output before making success claims') and when ('about to claim work is complete, fixed, or passing, before committing or creating PRs'). Has explicit trigger guidance.

Includes natural keywords users/Claude would encounter: 'complete', 'fixed', 'passing', 'committing', 'creating PRs', 'success claims'. These are terms that naturally appear when finishing work.

Clear niche focused on the specific moment before claiming completion - distinct from general testing skills or commit message skills. The 'evidence before assertions' principle is unique and unlikely to conflict.

Every section earns its place with actionable tables, clear patterns, and no explanation of concepts Claude already knows. The content is dense with useful information without padding.

Provides concrete verification patterns with specific examples (test commands, exit codes, red-green TDD cycle). The tables clearly distinguish correct vs incorrect approaches with executable guidance.

The 5-step Gate Function provides an explicit, sequenced workflow with clear validation checkpoints. The red-green regression test pattern explicitly includes verification loops.

Well-organized with clear sections (Overview, Gate Function, Common Failures, Red Flags, etc.). For a skill of this scope with no need for external references, the structure is appropriate and navigable.
