Quality

Content

77%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.

The skill is highly actionable with executable code and a well-sequenced, validated workflow, but its progressive disclosure is weak: the body is self-contained and duplicates the implementation-guide bundle instead of pointing to it, which also hurts token efficiency.

Suggestions

Replace the inline full-code blocks for Steps 1-5 with concise summaries plus a single signaled link to references/implementation-guide.md to avoid duplicating the bundle and reclaim token budget.

Reference the implementation guide explicitly (e.g., 'See [implementation-guide.md](references/implementation-guide.md) for complete patterns') so the bundle is discoverable and one level deep.

Move the Security Checklist currently living only in the implementation guide into the body (or link to it) so the workflow has an explicit completion checkpoint.

DimensionReasoningScore

Conciseness

The body is mostly lean and code-driven with little concept re-explanation, but it runs long and substantially duplicates the Steps 1-5 code already present in references/implementation-guide.md, so it could be tightened.

2 / 3

Actionability

Every step provides fully executable, import-complete TypeScript with real Clerk/svix calls and a concrete rate-limiting example — copy-paste ready.

3 / 3

Workflow Clarity

Steps 1-5 are clearly sequenced, each embeds validation (assertServerOnly, svix header checks, session-freshness checks), and the Error Handling table supplies feedback loops for recovery.

3 / 3

Progressive Disclosure

A references/implementation-guide.md bundle exists, but the body never links to or signals it, and content that belongs in that reference (the full Step 1-5 code) is duplicated inline rather than split out.

Description

90%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 cleanly states its purpose and trigger conditions with natural, distinctive phrasing, though the capability statement stays abstract rather than enumerating the concrete hardening actions the skill actually covers.

Suggestions

Expand the 'what' clause to name concrete actions (e.g., 'protect environment variables, harden middleware, secure API routes, verify webhooks, enforce session freshness') instead of the generic 'Implement security best practices'.

DimensionReasoningScore

Specificity

Names the domain and a single abstract action ('Implement security best practices with Clerk authentication') but does not list multiple concrete actions such as env-var protection, middleware hardening, or webhook verification that appear only in the body.

2 / 3

Completeness

Explicitly answers both what ('Implement security best practices with Clerk authentication') and when ('Use when securing your application, reviewing auth implementation, or hardening Clerk configuration'), with an explicit trigger clause.

3 / 3

Trigger Term Quality

Provides natural trigger phrases a user would say — 'clerk security', 'secure clerk', 'clerk best practices', 'clerk hardening' — giving good coverage of likely phrasings.

3 / 3

Distinctiveness Conflict Risk

Scoped to a clear Clerk-specific niche with distinctive Clerk-prefixed triggers, making it unlikely to fire for an unrelated skill.
