82%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 tight, code-forward reference that respects the token budget and gives executable examples for the core token-bucket case. The main weaknesses are coverage gaps (sliding window and Redis named but never shown), no explicit algorithm-selection or validation workflow, and minor structural room for a references file for distributed setups.
Suggestions
Add short, complete implementations (or a concrete Redis recipe, e.g., with a named library) for sliding window and Redis-based limiting, since both are promised in the description but never shown.
Include a one-line decision rule for choosing between the custom TokenBucket class and express-rate-limit middleware, and turn "Test under load" into a concrete verification command or step.
Move the distributed/Redis material into a references/ file (one level deep) if more than a few lines are needed, keeping SKILL.md as a lean overview with a clearly signaled link.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean: a pros/cons table, one executable class, one middleware config, a header block, a tier table, and short bullet lists. It never explains concepts Claude already knows (e.g., what rate limiting is), so every token earns its place. | 5 / 5 |
Actionability | The TokenBucket class and Express middleware are concrete and executable, but the sliding-window and Redis-based algorithms promised in the description receive no implementation, and the "Best Practices" bullets ("Monitor rate limit metrics", "Test under load") are abstract direction rather than instructive content. It is above 3 because the provided code is real and complete, not pseudocode. | 4 / 5 |
Workflow Clarity | The sections guide a reader from algorithm comparison to implementation to response headers, but there is no explicit sequence (e.g., when to use the custom class vs express-rate-limit, or how to wire Redis in for distributed limiting) and validation appears only as the bare bullet "Test under load" rather than a checkpoint. It is above 3 because the organization still makes the path reasonably unambiguous. | 4 / 5 |
Progressive Disclosure | A self-contained single file with well-organized sections and no nested references, which navigates cleanly. It falls short of 5 only because the body is slightly beyond the ~50-line simple-skill range and topics like Redis distributed limiting are mentioned without a reference file or detail, leaving a minor organizational gap. | 4 / 5 |
