85%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured skill body: a lean, actionable overview that assumes Claude's competence, a clearly sequenced workflow with explicit validation and error-recovery feedback loops, and properly progressive disclosure to three real, one-level-deep reference files. The only minor improvements are trimming the generic Resources links and specifying timing-safe signature comparison and retry/backoff parameters.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Dense and instructional — it assumes Claude's competence (no explanation of what webhooks or HMAC are) and every section carries operational content. The Resources section (RFC 2104 HMAC spec, generic OWASP link) is minor padding Claude doesn't need, keeping it just below the leanest anchor. | 4 / 5 |
Actionability | Highly concrete guidance — exact signature headers (X-Hub-Signature-256, Stripe-Signature), a specific API call (stripe.webhooks.constructEvent()), exact response codes, and exact output file paths. Small gaps remain: the HMAC comparison doesn't mention timing-safe/constant-time comparison, and retry counts and backoff for dead-letter handling are unspecified. | 4 / 5 |
Workflow Clarity | Eight clearly sequenced steps with an explicit validation checkpoint (step 8: replay tests with both valid and tampered signatures) and documented feedback loops for error recovery (the Error Handling table maps each failure mode to a concrete remedy). This is not a destructive operation, so no validation cap applies. | 5 / 5 |
Progressive Disclosure | The body is a well-sectioned ~65-line overview with three one-level-deep references (implementation.md, errors.md, examples.md), each clearly signaled with a descriptive link describing what it contains, and all three files exist in the references/ bundle. Content is appropriately split between overview and detail. | 5 / 5 |
