Quality

Content

100%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a strong, lean, single-purpose skill with executable examples in multiple languages, a clear core workflow, and a defensive fallback, with no wasted tokens.

Dimension	Reasoning	Score
Conciseness	The body is lean and code-focused, assuming Claude's competence: no padding explaining what EVM/ERC-20 is, a one-line motivator, concise "How It Works", and tight inline tips like "Do not hardcode 1_000_000".	3 / 3
Actionability	Provides fully executable, copy-paste-ready examples with imports across Python/web3, lru_cache, try/except fallback, Solidity normalizeToWad, TypeScript/ethers, and a `cast call` one-liner.	3 / 3
Workflow Clarity	The single-purpose task is unambiguous with a clear three-step sequence (query decimals at runtime, cache by chain+token, use decimal-safe math) plus an explicit error-recovery fallback with logging; no destructive/batch validation gap applies.	3 / 3
Progressive Disclosure	No bundle files are needed and the single SKILL.md is well-organized into When to Use, How It Works, Examples, and Rules sections, satisfying the simple-skill provision for progressive disclosure.	3 / 3
	Total	12 / 12 Passed

Description

82%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific, distinctive, and uses strong natural trigger terms, but it lacks an explicit "Use when..." trigger clause, capping completeness at 2.

Suggestions

Add an explicit trigger clause such as "Use when reading ERC-20 balances, pricing on-chain assets, or comparing token amounts across EVM chains."

Replace the audience-only "for bots, dashboards, and DeFi tools" phrasing with a concrete invocation trigger to satisfy the 'when' half of completeness.

Dimension	Reasoning	Score
Specificity	Lists several concrete capabilities in third person ("Prevent silent decimal mismatch bugs", "runtime decimal lookup", "chain-aware caching", "bridged-token precision drift", "safe normalization"), matching the anchor for multiple specific concrete actions.	3 / 3
Completeness	The "what" is clear, but the only "when" guidance is the audience clause "for bots, dashboards, and DeFi tools" rather than an explicit "Use when..." trigger, so per the guidelines completeness is capped at 2.	2 / 3
Trigger Term Quality	Covers natural domain terms a developer would say ("EVM chains", "decimals", "bridged-token", "DeFi tools", "bots, dashboards"), giving good coverage rather than only jargon or a single variation.	3 / 3
Distinctiveness Conflict Risk	The EVM token-decimals niche with bridged-token precision drift and chain-aware caching is specific and unlikely to trigger for unrelated skills.	3 / 3
