An excellent, lean skill body: executable examples for all three major Ethereum JS libraries, a proof-of-divergence snippet, common patterns for selectors/storage slots/address derivation, audit greps, and an explicit closing rule. The only structural improvement is moving the multi-library Examples into a references file for progressive disclosure.
Suggestions
Move the Examples section (ethers/viem/web3.js variants and common patterns) into references/examples.md and keep one quick-start snippet inline in SKILL.md, improving progressive disclosure while trimming the body.
Consider adding a one-line note on how to verify a hash is correct Keccak-256 (e.g., compare against a known test vector such as the empty-input hash c5d2460186f7233c927e7db2dcc703c0e500b653ca82273b7bfad8045d85a470) to give reviewers a validation checkpoint.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | No padding and no explanation of concepts Claude already knows; every section earns its place — the divergence demo proves the core claim, the examples cover three libraries, and the audit greps are immediately usable. Matches 'lean and efficient; every token earns its place.' | 5 / 5 |
Actionability | Copy-paste-ready executable code for ethers v6, viem, and web3.js, plus selector/typeHash/mapping-slot patterns, address derivation, and runnable grep commands for auditing a codebase. Specific examples cover the common cases. | 5 / 5 |
Workflow Clarity | A simple, single-purpose skill whose single action is unambiguous: 'never use crypto.createHash(\u0027sha3-256\u0027). Use Keccak-aware helpers from ethers, viem, web3, or another explicit Keccak implementation', reinforced with audit commands. The audit greps are read-only, so the destructive/batch validation cap does not apply. | 5 / 5 |
Progressive Disclosure | Well-organized sections with clear headers and everything inline is navigable, but the body is ~95 lines — above the under-50-line exception — and the Examples section (five subsections across three libraries plus patterns) is content that could be split into a references file to keep SKILL.md a leaner overview. | 4 / 5 |
