Quality

Content

65%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.

A well-structured overview that practices good progressive disclosure by delegating code and verification to references/rule.md. The trade-off is reduced actionability and workflow clarity in the body itself, where execution details and validation checkpoints live only in the reference.

Suggestions

Add one concrete executable check to the body (e.g., a one-line `curl -I ... | grep -i set-cookie` example) so the overview is actionable without opening the reference.

Tighten the redundancy between the intro paragraph and the Quick Reference bullets so each flag's rationale is stated once.

Surface a brief verification checkpoint in the body (e.g., "confirm Set-Cookie shows HttpOnly; Secure; SameSite=Strict") to make the workflow sequence explicit before delegating full checks to rule.md.

DimensionReasoningScore

Conciseness

The body is compact and mostly earns its tokens, but the intro paragraph and the Quick Reference bullets both re-explain what each flag prevents — a minor redundancy that could be trimmed without losing clarity.

4 / 5

Actionability

The Check/Fix/Code Review sections give concrete review criteria (flag missing HttpOnly, absent Secure, permissive SameSite) but no executable commands or code in the body itself — the actual curl/framework snippets live in references/rule.md, leaving key execution details out of the overview.

3 / 5

Workflow Clarity

The Check/Fix/Explain/Code Review sections read as parallel engagement modes rather than a sequenced workflow, and no explicit validation/verification checkpoint is present in the body (verification is delegated to rule.md), leaving sequence and checkpoints implicit.

3 / 5

Progressive Disclosure

The body is a lean overview that keeps bulk implementation in a single, clearly signaled one-level-deep reference (references/rule.md, verified to exist), with well-organized sections and easy navigation.

Description

87%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.

A concise, well-targeted description that clearly states capabilities and explicit trigger conditions with low conflict risk. Slight headroom remains on action specificity and synonym coverage.

DimensionReasoningScore

Specificity

Lists several concrete actions — "reviewing server-side session management", "setting up authentication middleware", "auditing cookie configuration in HTTP response headers" — but stops at three high-level actions rather than enumerating the full set of sub-tasks, leaving minor coverage gaps.

4 / 5

Completeness

Explicitly answers both what (review/set up/audit cookie-related security) and when ("Use when reviewing... setting up... or auditing...") with concrete trigger phrases, matching the top anchor.

5 / 5

Trigger Term Quality

Includes natural phrases users would say ("session management", "authentication middleware", "cookie configuration", "HTTP response headers") but omits common synonyms and specifics like "session cookies", "Secure/HttpOnly flags", or "CSRF".

4 / 5

Distinctiveness Conflict Risk

Targets a clear security niche (session cookie flags / auth middleware) with distinct triggers and minimal overlap risk against unrelated skills.
