Conciseness

The body is efficient and assumes competence — concrete query decomposition terms, statuses, and a compact report template with no padding or explanations of concepts Claude already knows. Minor trimmable content keeps it below lean anchor 5: the "it does not add Dexter's x_search tool, X API credentials, provider settings, slash commands, daemon routes, or runtime modules" disclaimer and the untrusted-evidence warning stated twice (Source Access Rules and the Evidence Note template section).

Actionability

Guidance is mostly executable for an instruction-only skill: an exact output path (`research/x-research/<safe-topic-slug>.md`), 3-5 query decomposition with specific signal terms (`bullish`, `upside`, `catalyst` vs `overvalued`, `bubble`, `risk`), enumerated coverage statuses, and a complete report skeleton. Minor gaps remain — "Source class" is never defined with concrete values, and there is no worked example of a query set for a sample entity.

Workflow Clarity

A clear six-step sequence (restate topic → decompose into 3-5 queries → record per-source coverage with explicit statuses → group by theme → synthesize sentiment → save and reference the path) with the per-source coverage-status recording acting as an implicit checkpoint. It falls short of anchor 5 because there is no explicit validation step (e.g., verifying the saved file exists or that every cited [n] appears in the Sources section), though the non-destructive nature keeps it solidly at 4 rather than 3.

Progressive Disclosure

The skill is self-contained with no references/, scripts/, or assets/ bundle directories, and nothing inlined that belongs in a separate file at its ~88-line scale. Sections (Source Access Rules, Workflow, Markdown Report Contract, Attribution) are well-organized and easy to navigate, so per the simple-skill guidance a well-organized single-file structure earns full marks.

Specificity

Names the domain precisely ("X/Twitter public sentiment research for recent market, company, product, or community discourse") and one concrete action (sentiment research), but does not list several distinct concrete actions the way a 4 or 5 requires. It is a single-capability description rather than a comprehensive action list.

Completeness

Explicitly answers both questions: the "what" ("X/Twitter public sentiment research for recent market, company, product, or community discourse") and the "when" via a concrete "Use when the brief asks what people are saying on X, Twitter sentiment, CT sentiment, public opinion..." clause with concrete trigger phrases. This matches the anchor-5 example structure exactly.

Trigger Term Quality

Strong natural-phrase coverage — "what people are saying on X", "Twitter sentiment", "CT sentiment", "public opinion", "expert posts", "social reaction" — including slang and bilingual variants. A few natural terms users might say (e.g. "tweets", "X sentiment", "stocktwits") are absent, which keeps it below the comprehensive anchor 5.

Distinctiveness Conflict Risk

The X/Twitter market-sentiment niche is distinct with dedicated triggers, but broader phrases like "public opinion" and "social reaction" create minor overlap risk with general research or social-media analysis skills — matching "mostly distinct; minor overlap risk" rather than the minimal-conflict anchor 5.
