Quality

Content

71%Weight 40%Scale 1-5

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

The body is highly actionable with executable commands, real examples, and strong error-recovery guidance, but it inverts its own progressive-disclosure design: content already split into references/errors.md and references/examples.md is duplicated inline while those files are never linked. Trimming the error table and examples to short summaries with links, and reconciling implementation.md (which describes a different market-data workflow referencing nonexistent config paths) with the CLI workflow, would tighten token use and navigation.

Suggestions

Link references/errors.md and references/examples.md from the body and condense the inline Error Handling table and Examples sections to brief summaries, removing the duplication that currently costs both conciseness and token budget.

Add explicit verification checkpoints to the workflow (e.g., confirm a transaction hash is 66 hex characters before querying, verify chain selection before retrying) to elevate workflow clarity toward anchor 5.

Reconcile references/implementation.md with the actual CLI workflow — it currently describes a different market-data/report workflow referencing ${CLAUDE_SKILL_DIR}/config/crypto-apis.env and Bash(crypto:explorer-*) that do not match the scripts or the body's instructions.

DimensionReasoningScore

Conciseness

The body is dense and mostly useful, but the 8-row Error Handling table and the three worked Examples substantially duplicate references/errors.md and references/examples.md, and the Output section inventories every output field. This matches 'mostly efficient but includes some unnecessary explanation or could be tightened' rather than anchor 4's minor trimmings.

3 / 5

Actionability

Instructions give copy-paste-ready commands with exact flags ('--detailed', '--chain polygon', '--history --tokens --limit 50', '--format json > file.json'), and examples use a real wallet address and the actual USDC contract, covering the common cases per anchor 5.

5 / 5

Workflow Clarity

A numbered instruction sequence with a conditional cross-chain fallback ('when the hash is not found on Ethereum') and a recovery-oriented error table provides most checkpoints, but there are no explicit validation/verify steps embedded in the workflow itself, so it sits below anchor 5.

4 / 5

Progressive Disclosure

Only references/implementation.md is linked from the body; references/errors.md and references/examples.md exist in the bundle but are unreachable from SKILL.md, and their content is inlined instead. Per the bundle-structure guideline this is 'references present but not clearly signaled; content that should be separate is inline' (anchor 3), not the well-signaled split of anchor 4.

Description

82%Weight 40%Scale 1-5

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

A strong description that explicitly covers what, when, and trigger phrases in a distinct blockchain-data niche. Its main weaknesses are near-synonymous generic verbs (plus a 'Process query and analyze' typo) and missing natural synonyms like 'crypto', 'Ethereum', or 'wallet balance' that would broaden trigger coverage.

DimensionReasoningScore

Specificity

The description names the domain and concrete objects ('blocks, transactions, and smart contracts') but the verbs 'Process query and analyze' are near-synonyms (and grammatically garbled) rather than several distinct concrete actions, so it falls short of the anchor-4 example of multiple specific actions while exceeding the domain-only anchor 2.

3 / 5

Completeness

It explicitly answers what it does ('Process query and analyze blockchain data including blocks, transactions, and smart contracts') and when to use it ('Use when querying blockchain data and transactions') plus concrete trigger phrases, matching the anchor-5 pattern; it is not anchor 4 because the 'when' is fully explicit rather than improvable.

5 / 5

Trigger Term Quality

'explore blockchain', 'query transactions', and 'check on-chain data' are natural phrases a user would say, but common variations and synonyms ('crypto', 'Ethereum', 'wallet balance', 'tx hash', 'look up a transaction') are missing, keeping it below comprehensive anchor-5 coverage.

4 / 5

Distinctiveness Conflict Risk

'blockchain data', 'on-chain data', and 'query transactions' define a clear niche with distinct triggers that would rarely fire for other skills, matching anchor 5.
