Conciseness

The body is lean and operational throughout: a one-sentence intro, a dense one-line-per-tool agent menu, and concrete setup/error sections with no explanations of concepts Claude already knows. Every line carries operational value (e.g., "Cache the result per agent for the session — schemas do not change between calls"), matching anchor 5.

Actionability

Provides exact curl commands for mesh_schema and mesh_request with full JSON body, exact env var names with validation specifics ("starts with 0x, and is 66 characters"), and real endpoints. It falls short of anchor 5 because only the API-key request shape is shown inline (x402/Inflow deferred to references) and the Examples section gives step outlines rather than copy-paste commands per common case.

Workflow Clarity

Setup is explicitly sequenced (choose payment path → verify .env → fetch schema → call) with a hard STOP checkpoint ("If none are configured, STOP and ask the user"), pre-call schema validation, a polling loop for async jobs, and a dedicated error-handling section with feedback loops (exponential backoff, credential re-check). This matches anchor 5's explicit validation plus error-recovery loops.

Progressive Disclosure

SKILL.md serves as an overview and agent menu, while detailed flows are split into four real, one-level-deep reference files, each linked inline with a clear label of its contents (e.g., "Setup and free-credit flow: references/heurist-api-key.md"). No nested references exist inside the reference files, matching anchor 5.

Specificity

Lists five concrete capability areas ("crypto token data, DeFi analytics, wallet intelligence, project research, and blockchain insights") through a named mechanism (Heurist Mesh agents). It falls short of anchor 5 because the single verb "Access" is less concrete than multiple distinct actions, but exceeds anchor 3's 1-2 action coverage.

Completeness

Explicitly answers both questions: the first sentence states what the skill does, and "Use when the user asks about token trends, DeFi protocols, wallet holdings, project due diligence, Twitter/X crypto sentiment, or deeper market analysis" gives six concrete trigger phrases. This matches the anchor 5 example pattern exactly.

Trigger Term Quality

Natural phrases users would actually say — "token trends, DeFi protocols, wallet holdings, project due diligence, Twitter/X crypto sentiment" — give good keyword coverage. A few common terms are missing (e.g., NFT, crypto prices, trending coins), keeping it below anchor 5 but well above anchor 3's partial coverage.

Distinctiveness Conflict Risk

The description is consistently scoped to crypto/blockchain data via Heurist Mesh, with triggers (DeFi protocols, wallet holdings, Twitter/X crypto sentiment) forming a clear niche with minimal overlap risk. The slightly broad "project research" is not enough to drop to anchor 4 since it sits inside an explicitly crypto-scoped sentence.
