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.
A well-structured, token-efficient overview body with excellent progressive disclosure to a real, one-level-deep references/rule.md. Its weaknesses are in-body actionability — the Check and Fix sections tell Claude what to do but not how, deferring all executable detail to the reference — and missing validation checkpoints in the Check/Fix workflow (no measure-confirm-reverify loop).
Suggestions
Add one minimal executable anchor to the Fix section, e.g. the module/nomodule snippet (`<script type="module" src="modern.js"></script><script nomodule src="legacy.js"></script>`) or a one-line Vite `build.target`/browserslist example, so the body is actionable without opening the reference.
Make the Check section concrete: name the measurement (e.g. 'Compare modern vs legacy bundle sizes in the build output; check Lighthouse "Serve modern code" audit or bundle analysis for ES5/polyfill payload') and add a verify-after-fix step (re-run the same audit) to close the workflow loop.
Trim the opening explainer sentence and the generic Code Review template phrasing, since both restate knowledge Claude already has.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean (~35 lines), well-sectioned (Quick Reference / Check / Fix / Explain / Code Review), and assumes Claude's competence with no library tutorials or padding. It is not a 5 because the opening sentence ("Modern browsers can execute ES6+ code faster and more efficiently; serving them transpiled ES5 with polyfills adds unnecessary weight") explains a concept Claude already knows, and the Code Review section's generic template text could be trimmed. | 4 / 5 |
Actionability | Concrete technique names appear ("differential serving (module/nomodule)", "set a modern target"), but the body gives only high-level direction with no commands, config snippets, or measurement steps — e.g. "Analyze the project's JavaScript output" and "Update the build configuration" without saying how. The executable detail (Vite target, browserslist, module/nomodule HTML) lives one hop away in references/rule.md, so guidance is present but incomplete rather than minimally present (not 2) or mostly executable in-body (not 4). | 3 / 5 |
Workflow Clarity | A coherent Check → Fix → Explain → Code Review sequence exists, but there are no validation checkpoints: no method for confirming the issue in the body, and no verify-after-fix step (e.g. re-run Lighthouse or compare bundle sizes). The sequence is clearly present and coherent (above the 2 anchor) but checkpoints are missing or deferred to the reference file, matching the 3 anchor. | 3 / 5 |
Progressive Disclosure | The body is a concise overview with a clearly signaled, one-level-deep reference — "For full implementation details, code examples, and framework-specific guidance, see `references/rule.md`" — and the referenced file exists with exactly that content (differential-serving HTML, Vite/browserslist configs, best practices) with no further nesting. Content is appropriately split and navigation is trivial, matching the 5 anchor; a 4 would require organization gaps, which are absent. | 5 / 5 |
