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 includes an explicit 'Use when...' clause with natural trigger terms. It is concise, well-structured, and distinctive enough to avoid conflicts with other skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'transactional email patterns', 'React Email templates', 'domain configuration', and 'webhook handling' — these are distinct, concrete capabilities. | 3 / 3 |
Completeness | Clearly answers both 'what' (Resend transactional email patterns, React Email templates, domain configuration, webhook handling) and 'when' (Use when sending emails, building email templates, or configuring email delivery) with an explicit 'Use when...' clause. | 3 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'sending emails', 'email templates', 'email delivery', 'Resend', 'React Email', 'domain configuration', 'webhook'. Good coverage of terms a user would naturally use when needing this skill. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive due to the specific mention of 'Resend' (a specific email API provider) and 'React Email' (a specific templating framework). These are niche enough to avoid conflicts with generic email or communication skills. | 3 / 3 |

Implementation
92%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 provides concise, actionable guidance for Resend email integration. Its strengths are executable code examples, a clear verification workflow with validation checkpoints, and efficient use of tokens. The main weakness is that REFERENCE.md is referenced but not provided in the bundle, and the references to it are scattered rather than consolidated in a single navigation section.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient. It doesn't explain what Resend is or how email works. Every section delivers actionable information without padding. The only minor verbosity is the repeated 'from' field in both send examples, but that serves as a complete, copy-paste-ready pattern. | 3 / 3 |
Actionability | Provides fully executable TypeScript code for sending emails (both plain text and React Email), a concrete bash command for previewing templates, specific DNS verification commands (`dig TXT`), and a curl command for testing webhooks. All examples are copy-paste ready with realistic values. | 3 / 3 |
Workflow Clarity | The Quick Verification Workflow provides a clear 5-step sequence with explicit validation checkpoints (verify DNS propagation, confirm SPF/DKIM pass, assert 200 response) and an error recovery step (re-check DNS, API keys, webhook secret). Domain configuration also follows a clear sequence with a post-verify validation step. | 3 / 3 |
Progressive Disclosure | The skill references REFERENCE.md for detailed templates, webhook handlers, and troubleshooting, which is good one-level-deep disclosure. However, no bundle files were provided, so we can't confirm REFERENCE.md exists. The references are mentioned in two separate places (React Email Templates section and Webhook Handling section) rather than being consolidated in a clear navigation section, making discovery slightly less organized. | 2 / 3 |
