Quality
Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a strong skill description that clearly identifies the specific technology stack (Resend, React Email), lists concrete capabilities, and provides explicit trigger guidance via a 'Use when...' clause. The description is concise, uses third person voice, and covers natural user language well.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'transactional email patterns', 'React Email templates', 'domain configuration', and 'webhook handling' — these are all distinct, concrete capabilities. | 3 / 3 |
Completeness | Clearly answers both 'what' (Resend transactional email patterns, React Email templates, domain configuration, webhook handling) and 'when' (explicit 'Use when sending emails, building email templates, or configuring email delivery'). | 3 / 3 |
Trigger Term Quality | Includes strong natural keywords users would say: 'sending emails', 'email templates', 'email delivery', 'Resend', 'React Email', 'domain configuration', 'webhook'. These cover the main ways a user would phrase requests related to this skill. | 3 / 3 |
Distinctiveness Conflict Risk | The mention of 'Resend' and 'React Email' as specific technologies, combined with 'transactional email' and 'webhook handling', creates a clear niche that is unlikely to conflict with generic coding or other email-related skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-crafted skill that balances conciseness with actionability. It provides executable code examples, a clear verification workflow with validation checkpoints, and appropriately delegates detailed reference material to a separate file. The content respects Claude's intelligence by avoiding unnecessary explanations while still being comprehensive enough to cover setup, sending, domain configuration, and webhook handling.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient. It doesn't explain what Resend is or how email works—it jumps straight into setup and usage. Every section earns its place with minimal filler. | 3 / 3 |
Actionability | Provides fully executable TypeScript code for sending emails (both plain text and React templates), concrete bash commands for setup and preview, and specific DNS verification commands. Copy-paste ready. | 3 / 3 |
Workflow Clarity | The Quick Verification Workflow provides a clear numbered sequence with explicit validation checkpoints (dig TXT to confirm DNS, check SPF/DKIM headers, assert 200 on webhook test) and an error recovery step if verification fails. | 3 / 3 |
Progressive Disclosure | The SKILL.md serves as a clear overview with quick-start content inline, while appropriately deferring detailed template patterns, webhook handler examples, and troubleshooting to REFERENCE.md with well-signaled one-level-deep references. | 3 / 3 |
Total | 12 / 12 Passed |
