Conciseness

The body avoids explaining concepts Claude already knows, but carries notable redundancy: the 'OSS-only pledge' section repeats the Overview's paid-tools sentence nearly verbatim ("Paid tools (Burp Suite, Nessus, Splunk, CrowdStrike, SonarQube, DOM Invader, Hackvertor) appear only as 'if you already have it' notes"), the ~40-line dot routing graph duplicates the routing table, and the 'Quick reference' table re-lists all 15 references already enumerated in the routing table. This fits 'mostly efficient but includes some unnecessary explanation or could be tightened' (3) better than 4, where only minor instances would need trimming.

Actionability

Guidance is highly concrete and executable for an instruction-only skill: a numbered dispatch contract pinning exact model tiers ("preferred `gpt-5.6 sol` (pinned); fallback `claude-opus-4.x max` or `opus 5 max`"), a routing table mapping task phrasing to exact reference paths, and explicit ack semantics ("Ack for `staging.example.com` does not authorize `prod.example.com`"). It stops short of 5 because the fan-out section depends on an external convention ("per `superpowers:dispatching-parallel-agents`") not present in the bundle, and the threat-model caveat in gate item 5 ('NOT defense in depth...') is analysis commentary rather than instruction.

Workflow Clarity

The multi-step orchestration is clearly sequenced with explicit validation checkpoints: the authorization gate fires before dispatch ('The gate is safety-critical and runs in main context first'), ack must precede any live-target action ('Proceed only after ack. No ack → no live-target action'), scope changes force re-confirmation, sub-agents refuse on missing ack_state, and there are error-recovery paths ('If the user declines... the orchestrator stops, explains why, and offers Track A alternatives') plus checklists ('Common mistakes', 'Never do'). This matches the 5 anchor: clear sequence, explicit validation, feedback loops, and checklists — the batch fan-out is also gated up front, so the destructive/batch cap does not apply.

Progressive Disclosure

SKILL.md is a pure router: all 15 referenced files (`references/authorization-disclaimer.md` through `references/aradotso-ai-security.md`) exist in the bundle, each is signaled with explicit 'SEE: references/<doc>.md' pointers, and cross-links inside references point only to siblings at the same tier (one level deep, no nested chains). The body explicitly forbids inlining reference bodies ('The main context never inlines a reference doc's body') and provides a quick-reference index table, matching the 5 anchor for clear, well-signaled, one-level-deep navigation.

Specificity

The description lists many concrete capability areas — "pentest, vuln testing (XSS, SSRF, CSRF, business-logic, Host header), threat modeling (STRIDE, ATT&CK), Sigma rules, SAST, code audit, AI/LLM red-team, or replacing paid tools (Burp, Nessus, Splunk) with OSS" — which matches the anchor 'lists several specific actions; minor gaps in coverage'. It falls short of the 5 anchor because capabilities are enumerated as noun phrases rather than explicit actions (the verbs 'analyze, test, and harden' appear only in the body, not the description), so the 'what it does' is partly implied.

Completeness

The 'what' is clear (OSS-only security skill covering the listed domains), but there is no 'Use when...' clause or equivalent explicit trigger guidance, so per the judging guidelines completeness is capped at 3 ('what' clear, 'when' missing or only weakly implied by the domain list).

Trigger Term Quality

Trigger coverage is strong and natural: users would genuinely say "OWASP Top 10", "pentest", "XSS", "SSRF", "CSRF", "threat modeling", "STRIDE", "code audit", "Sigma rules", and tool names "Burp, Nessus, Splunk". This fits 'good keyword coverage; a few natural terms missing' (4) rather than 5, since common variations like 'ethical hacking', 'security audit/review', 'vulnerability assessment', and 'web app security' are absent.

Distinctiveness Conflict Risk

The offensive/testing framing ("pentest", "vuln testing", "red-team") is somewhat distinct, but terms like "XSS", "CSRF", and "code audit" overlap heavily with this repo's existing defensive plugins (xss-prevention, csrf-protection, etc.) and the description gives no signal distinguishing finding-vs-fixing. This matches anchor 3, 'somewhat specific but could still overlap with similar skills', rather than 4 because the overlap with closely related skills is more than minor.
