Conciseness

The ~30-line body is lean and assumes Claude's competence: a compact template for the status section, a five-item allow-list, a four-item never-list, one exact self-check command, and two-line exit criteria. Every line adds a rule Claude could not infer, with no padding or explanation of known concepts — matching the 'lean and efficient; every token earns its place' anchor.

Actionability

Guidance is concrete: an exact status-section shape with placeholder syntax, a fixed verdict vocabulary (VERIFIED | NOT VERIFIED | NOT FIXED | PARTIALLY FIXED | IMPLEMENTED | PROPOSED), and the copy-paste command "python3 tools/claim_audit.py --report report.md --facts ledger_facts.json". It falls short of fully executable because that auditor script and the ledger_facts.json format are not bundled with the skill (no references/, scripts/, or assets/ exist), leaving the core self-check mechanism unrunnable from the skill alone — a concrete command with a real gap rather than a minor one.

Workflow Clarity

The workflow is unambiguous for this simple single-purpose skill: construct the report to the required shape using only allowed statements, run the auditor, and "If it flags a line, rewrite the line from the ledger; do not argue with the checker" — an explicit validate→fix→retry feedback loop — with exit criteria of "required shape and zero auditor flags". The validation step, error-recovery loop, and completion checklist match the top anchor.

Progressive Disclosure

For an under-50-line skill with well-organized sections (Required shape, Allowed, Never, Self-check, Exit criteria) a 5 is available, but the body references external files — tools/claim_audit.py and ledger_facts.json — that are not present in the bundle (no references/, scripts/, or assets/ directories exist), so the reference is dangling and a reader cannot navigate to the auditor's definition. That is 'good structure with minor organization gaps' rather than fully clear navigation.

Specificity

The description enumerates multiple concrete actions — "Write status and completion reports", "limits first, every completion line tied to an item ID and its exact verifier verdict, copied numbers, named environments", and "self-check them with the allow-list auditor" — giving comprehensive, explicit coverage of what the skill does. It clearly matches the anchor for multiple specific concrete actions rather than the anchor 4 example, which would leave minor gaps in coverage.

Completeness

It explicitly answers both what ("Write status and completion reports that can never overstate what is done … self-check them with the allow-list auditor before sending") and when ("Use for every final answer, status update, PR description, or handoff that reports work") with concrete trigger phrases. Not the level below (4) because the 'when' clause is explicit and enumerates concrete triggering situations rather than being merely serviceable.

Trigger Term Quality

Natural phrases users would say are present: "status update", "PR description", "handoff", "final answer", "completion reports". A few natural synonyms and variations are missing (e.g. "progress report", "wrap-up", "work summary"), which fits the 'good keyword coverage; a few natural terms missing' anchor rather than the comprehensive synonym coverage of a 5.

Distinctiveness Conflict Risk

The niche — honesty-gated completion reporting with an auditor self-check — is distinct, and triggers like "handoff" and "PR description" are specific to it. However, the very broad trigger "every final answer … that reports work" gives minor overlap risk with general reporting/communication skills, so it sits at 'mostly distinct' rather than a clear niche with minimal conflict risk.
