Conciseness

The body is dense and operational throughout — tables, gates, and templates with no padding explaining concepts Claude already knows — and it assumes competence (e.g., mentions WAF, CVSS, SSRF without defining them). Not 5: at ~450 lines there is noticeable redundancy with the reference files (severity anchors, SLA table, and calibration rules summarized inline though the full reference exists) and the 15-item external-standards bibliography could be trimmed to the ones actually consulted. Not 3: almost every section carries decision-relevant rules rather than filler.

Actionability

Guidance is fully executable: a concrete validation command ('node references/validate-findings.mjs findings.json'), exact record fields to use ('location', 'trace[]', 'counterevidence', 'ext.fixed_in'), six copy-paste-ready disposition templates, and a per-disposition required-fields table. Not 4: even the edge cases (writing back verdicts, re-running the validator, recording 'Fixed' only after ship) are given concrete procedures, leaving no gaps for common cases.

Workflow Clarity

Steps 1–7 are clearly sequenced with explicit validation checkpoints and feedback loops: the Step 6 writeup checklist, the Step 7 fix-verification loop ('re-run the original check… re-run the validator'), the High/Critical acceptance checklist, and error-recovery guidance ('If a check fails, downgrade rather than delete'; re-run the validator after editing records). This matches the top anchor's validate → fix → re-validate pattern. Not 4: checkpoints are explicit and repeated at every state-changing point, not just present.

Progressive Disclosure

The body is a well-structured overview with one-level-deep, clearly signaled references, all of which exist and match their descriptions: severity-calibration.md, findings-format.md, verification.md, fix-verification.md, independent-verification.md, plus validate-findings.mjs and to-sarif.mjs. Content is appropriately split — full rules in references, workable summaries inline — and navigation is aided by a consolidated References section. Not 4: every reference is annotated with what it contains and when to open it, with no buried or nested chains.

Specificity

The description lists multiple concrete actions — 'Triage a single security finding,' 'calibrated severity, a mitigation plan, false-positive justification, or accepted-risk writeup' — with comprehensive coverage of the skill's outputs. Not 4: the action set is specific and complete rather than having minor gaps; the voice is correctly third person ('Triage').

Completeness

It explicitly answers both parts: 'what' is 'Triage a single security finding — from a scanner, audit, advisory, report, or a findings.json record — to a defensible disposition,' and 'when' is the explicit 'Use when the user mentions…' clause ending with 'or has a single security finding and needs to decide what to do.' Not 4: the 'when' is not merely present but highly specific with concrete trigger phrases.

Trigger Term Quality

Trigger coverage is comprehensive and natural, including synonyms and record-format terms: 'triage this finding,' 'is this a real vulnerability,' 'false positive,' 'accept this risk,' 'CVSS this,' 'is this really high,' 'hardening note,' 'findings.json,' 'sign off on.' Not 4: these are phrases a user would actually say verbatim, not just generic keywords with a few gaps.

Distinctiveness Conflict Risk

The niche is clear — single-finding disposition/close-the-loop, explicitly distinct from skills that generate findings — and most triggers ('disposition,' 'should we fix this,' 'accept this risk') point only here. Not 5: a few trigger terms ('security ticket,' 'severity calibration,' 'findings.json,' 'mitigation plan') overlap with closely related security skills in the same domain that own those artifacts; not 3: the core disposition framing is unmistakable.
