Quality

Content

75%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is a lean, highly actionable security-testing runbook with concrete commands, payloads, CVSS vectors, and an explicit validation contract. Its main limitation is that two attack vectors remain prose-only and the workflow is sectioned by topic rather than presented as a strict numbered pipeline with per-stage checkpoints.

Suggestions

Add executable commands or one-liners for the embedding-inversion and error-oracle vectors so every attack vector has runnable guidance, not just prose.

Reformat the audit workflow as a single numbered end-to-end pipeline with an explicit 'Validate the finding before promoting' checkpoint between exploitation and chain promotion.

Consider externalising the PoC payloads and CVSS tables into a references/ file so SKILL.md stays a lean overview with one-level-deep navigation.

DimensionReasoningScore

Conciseness

The body is dense and assumes Claude's security competence, with copy-paste grep blocks and compact payloads; only the opening framing paragraph and a couple of editorial lines ('Disclosure usually beats prompt injection...') could be trimmed.

4 / 5

Actionability

Executable grep commands, copy-paste PoC prompt strings, and concrete regex success/negative patterns cover the common cases, but the embedding-inversion and error-oracle vectors are described in prose without runnable commands, leaving minor gaps.

4 / 5

Workflow Clarity

A clear recognize → choose-vector → exploit → validate sequence is present, with the 'validate_finding' contract (success_patterns, negative_command, negative_patterns) acting as the validation checkpoint; the sequence is sectioned by topic rather than a strictly numbered end-to-end pipeline, leaving minor gaps.

4 / 5

Progressive Disclosure

A single self-contained SKILL.md is organised into eight clearly numbered, navigable sections with no nested references; at ~127 lines it is denser than the 'simple skill' case, so it sits just below the well-organised-sections ceiling of 5.

Description

70%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific, well-targeted to a distinct OWASP niche, and rich in relevant trigger terms, but it omits an explicit 'Use when...' trigger clause, which caps completeness. Adding a concrete usage-trigger sentence would lift the weakest dimension.

Suggestions

Append an explicit 'Use when...' clause naming concrete trigger phrases, e.g. 'Use when testing LLM apps for data leakage, cross-tenant RAG disclosure, system-prompt extraction, or training-data memorisation.'

Add natural-synonym trigger terms ('data leak', 'data exposure', 'prompt leakage') alongside the technical jargon to broaden when-to-use matching.

Consider a second action verb (e.g. 'Hunt and validate...') to move specificity from one enumerated action toward multiple concrete actions.

DimensionReasoningScore

Specificity

A single concrete verb ('Hunt') is used, but it enumerates five specific disclosure targets (PII, secrets, internal source, model details, other-tenant data) across three mechanisms, giving broad coverage with only a minor gap in action-verb diversity.

4 / 5

Completeness

The 'what' is clearly stated ('Hunt LLM sensitive-information disclosure...') but there is no 'Use when...' clause or equivalent explicit trigger guidance, capping completeness at 3 per the rubric guideline.

3 / 5

Trigger Term Quality

Strong security-niche keywords ('sensitive-information disclosure', 'PII', 'secrets', 'training-data extraction') that a tester would naturally use, though natural synonyms like 'leak' or 'exposure' are absent.

4 / 5

Distinctiveness Conflict Risk

The OWASP LLM02:2025 reference pins a clear, narrow niche (disclosure vs. injection) with distinct triggers and minimal overlap risk against other skills.
