Mostly efficient but restates the same core message across four overlapping sections ("What Counts as Evidence", "Recognizing Unverified Claims", "Why Partial Verification Fails", "Key Patterns"), and "Why This Matters" adds motivational padding that could be trimmed.

Gives a concrete 5-step procedure (Identify, Run, Read, Verify, Then claim) and an evidence table mapping each claim type to the specific proof required; as an instruction-only skill the actionable guidance is specific and complete.

Clear sequenced workflow with an explicit validation checkpoint and feedback loop ("If no: state actual status with evidence" / "If yes: state claim with evidence"), plus red-green guidance for regression tests.

Self-contained single-file skill with no bundle files and well-organized headed sections; per the simple-skills note, well-organized sections without external references earn full marks.

Lists multiple concrete actions — "Enforces fresh verification evidence" and "requiring command execution, output inspection, and exit code confirmation" — rather than vague language.

Explicitly answers both what ("Enforces fresh verification evidence before any completion or success claims") and when (a dedicated "Use when..." clause listing trigger situations).

Covers natural terms users would actually say — "done", "fixed", "tests pass", "build succeeds", "committing, creating PRs" — plus explicit synonym coverage.

Occupies a clear niche (verification before completion claims) with distinct, specific triggers unlikely to overlap with other skills.
