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.
The body is concise, actionable, and well-organized with a clear validated domain-setup workflow and sharp gotchas that capture non-obvious failure modes. Its main gap is the absence of an executable send/template code snippet to complement the install and dev-preview commands.
Suggestions
Add a minimal copy-paste send example (e.g. `resend.emails.send({ from, to, react: <Template/>, subject })`) so the core action is fully executable, not just described.
Promote the webhook signature verification into a short numbered checklist or code block (verify raw body -> return 400 on failure / 200 on success) to make that validation step explicit and reproducible.
Note the event names (email.delivered/bounced/complained) are already present; consider grouping them under a Webhooks section header to keep the Gotchas list scannable.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Lean and efficient; it assumes Claude's competence, presents only non-obvious gotchas and concrete commands, and every token earns its place without explaining basic concepts. | 5 / 5 |
Actionability | Provides concrete, executable guidance (verify call, dig command, curl smoke test, npm install, npx email dev) but lacks a copy-paste-ready send/verify code example for the core send path. | 4 / 5 |
Workflow Clarity | The Domain setup section is a clear numbered sequence with verification checkpoints (dig, header pass check, webhook 200 smoke test), though webhook signature verification is described in prose rather than as a sequenced validation step. | 4 / 5 |
Progressive Disclosure | A compact single-file skill under 50 lines with no need for external references; it is well-organized into clear sections (Gotchas, Domain setup, Templates), qualifying for the simple-skill exception. | 5 / 5 |
