65%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 maximally concise and cleanly organized, but it reads as a skeleton rather than a skill: it points at a directory and gestures at schemas, types, and testing without a single executable command or code example. An agent following it would have to invent nearly all of the implementation details.
Suggestions
Add a minimal executable Fastify route example (handler registration plus JSON schema) so step 1-2 are copy-paste ready rather than descriptive.
Replace 'Test it' with a concrete validation checkpoint, e.g., 'Run `npm test src/routes/<name>.test.ts` and fix failures before finishing', including a retry loop.
Specify the schema/type technology in use (e.g., TypeBox or JSON Schema) and the command that keeps types in sync, turning 'Make sure the types are in sync' into an actionable step.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is a 13-line instruction with zero padding — no explanation of what Fastify is, what a route handler is, or how testing works. It assumes Claude's competence entirely; every token earns its place, matching the 'lean and efficient' anchor exactly. | 5 / 5 |
Actionability | Only one concrete detail exists (the `src/routes/` directory); 'Add the request and response schema' names no schema technology (JSON schema, TypeBox, Zod), 'Make sure the types are in sync' gives no command or method, and 'Test it' specifies no test runner or command. This matches anchor 2 ('minimal concrete guidance; high-level hints but missing the specific steps to execute') — not level 3, because there is no partially-executable code, only hints. | 2 / 5 |
Workflow Clarity | The four steps form a coherent sequence ending with a validation gesture ('Test it'), mirroring anchor 3's example ('1. Unpack 2. Edit 3. Repack 4. Test the output') — steps listed, but checkpoints are missing or implicit since no command, expected outcome, or failure handling is given. Not level 4, which requires most checkpoints concretely present. | 3 / 5 |
Progressive Disclosure | This is a simple skill under 50 lines with no bundle files (no references/, scripts/, or assets/ directories exist) and no need for external references; per the rubric's simple-skills guideline, well-organized concise sections earn a 5. The single '## Steps' section is appropriately scoped with no inlined bulk content. | 5 / 5 |
