Conciseness

The body is efficient and assumes competence, but has minor trimmable redundancy: read-only/no-trading is stated three times ("This skill is read-only", "Never execute trades or convert the result into trading instructions", "not trade instructions") and "Prefer compare endpoints" appears in Step 2, Step 3, and Key rule 1. Not anchor 5 because those repeats mean not every token earns its place; above anchor 3 because the padding is minor with no explanation of concepts Claude already knows.

Actionability

Fully executable copy-paste curl commands with the X-API-Key header and concrete query params, a request-to-endpoint mapping table naming the exact fields, a working env-var probe, and a concrete output template. Examples cover the common cases (single-source, multi-source snapshot, multi-ticker), matching the anchor-5 example pattern.

Workflow Clarity

A clear four-step sequence (ensure API key → identify need → execute → present) with an explicit validation checkpoint: the ADANOS_API_KEY probe branches to remediation ("If ADANOS_API_KEY_MISSING, ask the user to set..."). Not anchor 5 because there is no recovery guidance for failed API responses (e.g., 401 or HTTP errors after execution); above anchor 3 because the key check is an explicit checkpoint with a feedback path, and the read-only nature means no destructive/batch validation cap applies.

Progressive Disclosure

Well-organized sections keep the body at quick-start level while a single one-level-deep reference (references/api_reference.md, verified to exist) is clearly signaled with its contents ("endpoint guide, field meanings, and example workflows") and an explicit read trigger ("when you need the exact field names, query parameters, or recommended answer patterns"). Not anchor 4 because the split is appropriate and navigation is easy, with no buried or nested references.

Specificity

"Fetch normalized stock sentiment across Reddit, X.com, financial news, and Polymarket from the Adanos Finance API: buzz score, bullish percentage, mention or trade counts, and trend" names the API, all four sources, and the concrete data fields returned — comprehensive coverage of the skill's concrete actions. Not anchor 4 because the coverage of the fetch capability and its outputs is complete rather than having minor gaps.

Completeness

Explicitly answers both what ("Fetch normalized stock sentiment... buzz score, bullish percentage, mention or trade counts, and trend") and when ("Use this skill whenever the user asks...") with concrete trigger phrases, matching the anchor-5 example pattern. Not anchor 4 because the 'when' clause is fully explicit with specific trigger scenarios rather than merely present.

Trigger Term Quality

Natural user phrasings are comprehensively covered: "how much a stock is being discussed", "how hot it is on social platforms", "how many Reddit mentions or Polymarket bets a company has", "whether Reddit, X, and news agree", "compare stock buzz and sentiment across tickers", plus terms like buzz, bullish, trend, and tickers. Not anchor 4 because common synonyms are present rather than a few missing.

Distinctiveness Conflict Risk

A clear niche (stock sentiment via the Adanos Finance API across named platforms) with distinct triggers and an explicit boundary ("Read-only: it never places trades or modifies anything") gives minimal conflict risk. Uses third person ("Fetch"), so no voice penalty; not anchor 4 because the platform-specific triggers make overlap with other skills unlikely.
