Content

80%Weight 40%Scale 1-3

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

A strong, action-dense API security methodology with executable commands and payloads and a clear 10-phase sequence plus self-check. Its main weaknesses are absent validation/feedback loops for destructive and batch operations, and two broken inline references combined with inline-heavy detail that limits progressive disclosure.

Suggestions

Add explicit validate→fix→retry checkpoints for destructive and batch operations (e.g. after BOLA/IDOR traversal and batch-injection tests, state how to confirm impact and what to do on failure) to lift workflow_clarity to 3.

Fix or remove the dangling references to ../field-journal/precedent-pentest.md and ../tool-index.md, which do not exist in the bundle and create broken navigation.

Move the bulk of the per-phase checklists into the existing references (or phase-specific files) and keep SKILL.md as a concise overview with one-level-deep pointers to improve progressive_disclosure.

DimensionReasoningScore

Conciseness

The body is action-dense with minimal concept padding — it skips explaining what an API or JWT is and goes straight to attack checklists and payloads, though its breadth (4 protocols, 10 phases) makes it long; every section earns its tokens. Not a 2 because there is no 'PDF is a common format...' style filler.

3 / 3

Actionability

Provides concrete executable commands and payloads throughout — e.g. 'python3 jwt_tool.py <JWT> -X k -pk public.pem', 'jwt_tool -C -d wordlist.txt', specific injection JSON {'username': {'$gt': ''}} — matching copy-paste-ready guidance.

3 / 3

Workflow Clarity

The 10 phases are clearly sequenced and framed by an ACTION REQUIRED prelude and a completion self-check, but destructive/batch operations (authz bypass, DoS, batch injection) lack explicit validate→fix→retry feedback loops, which caps the score at 2 per the rubric guideline. Not a 3 because validation checkpoints are implicit rather than stated; not a 1 because sequencing is explicit and a self-check exists.

2 / 3

Progressive Disclosure

Two real one-level-deep references (references/rest-graphql-testing.md, references/jwt-oauth-testing.md) are clearly signaled, but the body also cites missing external paths (../field-journal/precedent-pentest.md, ../tool-index.md) and keeps the bulk of the 10-phase detail inline rather than splitting it out. Not a 3 due to broken inline references and inline-heavy structure; not a 1 because there is genuine one-level reference signaling.

Description

100%Weight 40%Scale 1-3

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 concise, third person, uses an explicit 'Use for' trigger, and names concrete capabilities plus natural protocol terms. It cleanly satisfies the what/when/which-niche requirements with no over-claiming or padding.

DimensionReasoningScore

Specificity

Lists multiple concrete actions across domains — 'discovery, authentication, authorization, rate-limit, and CI/CD testing' — matching the anchor for enumerating several specific concrete actions.

3 / 3

Completeness

Answers both what (authorized security assessment across the listed domains) and when via the explicit 'Use for authorized security assessment of...' trigger clause.

3 / 3

Trigger Term Quality

Uses natural terms a user would say ('REST, GraphQL, WebSocket, or SOAP APIs', 'security assessment') with good coverage of the common protocol variations.

3 / 3

Distinctiveness Conflict Risk

A clear niche — authorized API security testing scoped to specific protocols — with distinct triggers unlikely to fire for unrelated skills.
