Conciseness

The body is lean with no concept explanations or padding: every tool gets a single-line description ('getGlobal — Total market cap, BTC dominance, 24h volume'), and the ID section is maximally terse ('Pattern: {symbol}-{name} lowercase. Examples: btc-bitcoin, eth-ethereum, sol-solana.'). This matches the anchor 'Lean and efficient; assumes Claude's competence; every token earns its place' rather than 4, since there is no over-explanation to trim.

Actionability

Setup guidance is copy-paste ready (complete mcpServers JSON block and '/plugin marketplace add coinpaprika/claude-marketplace' commands) and concrete ID examples are given. It falls short of anchor 5 because no example tool invocation pairs a tool with an argument (e.g., getTickersById with coin_id 'btc-bitcoin'), leaving the most common call pattern undemonstrated; it is above anchor 3 since all guidance shown is executable, not pseudocode.

Workflow Clarity

Sections sequence naturally (Setup → Tools → Coin ID Format → Rate Limits) and the ID section provides a real checkpoint: 'Use search or resolveId if unsure of the correct ID.' This fits anchor 4's 'clear sequence with most checkpoints present; minor validation gaps' — it lacks explicit error-recovery guidance (e.g., what to do on a failed call), so it does not reach 5, while the resolveId fallback keeps it above anchor 3.

Progressive Disclosure

With no bundle files present and a ~50-line body organized into clear sections (Setup, Available MCP Tools, Coin ID Format, Rate Limits), the skill needs no external references beyond the clearly signaled one-level 'Docs: https://docs.coinpaprika.com' link. The 29-tool catalog is compressed to 13 one-liner lines that belong inline, matching the guideline that a short skill with no need for external references scores 5 with well-organized sections.

Specificity

It lists several concrete capabilities — 'prices, tickers, OHLCV, exchanges, contract lookups for 12,000+ coins and 350+ exchanges' — plus concrete setup instructions, matching anchor 4 ('lists several specific actions; minor gaps in coverage'). It does not reach 5 because all actions sit under the single verb 'Access' and several capability areas (search, price conversion, people/tags) are absent; it is above 3, which requires only 1-2 concrete actions.

Completeness

The 'what' is clear and specific ('Access cryptocurrency market data from CoinPaprika: prices, tickers, OHLCV, exchanges, contract lookups'), but there is no 'Use when...' clause or equivalent trigger guidance — the 'Install MCP...' and '/plugin marketplace add' text is setup instruction, not usage triggers. Per the guideline that a missing 'Use when...' clause caps completeness at 3, this matches anchor 3 ('has a clear what but when is missing or only weakly implied').

Trigger Term Quality

Strong natural domain terms are present: 'cryptocurrency market data', 'prices', 'tickers', 'OHLCV', 'exchanges', 'contract lookups'. This fits anchor 4 ('good keyword coverage; a few natural terms missing'): the colloquial 'crypto' synonym, 'candles/candlesticks' (what users say more than OHLCV), 'market cap', and 'bitcoin' are missing, keeping it below 5, while coverage clearly exceeds anchor 3's 'missing common variations'.

Distinctiveness Conflict Risk

Naming the specific source ('from CoinPaprika') with scale details ('12,000+ coins and 350+ exchanges') carves a clear niche, fitting anchor 4 ('mostly distinct; minor overlap risk with closely related skills'). It is not 5 because generic crypto-price queries could also match other market-data skills (e.g., CoinGecko/CMC) since terms like 'prices' and 'tickers' are not source-unique, and it is well above 3's genericness.
