Conciseness

The body is dense and operational — command blocks with inline comments, a compact tier table, and specifics Claude could not guess (cache paths, env-var names, column flags, tier thresholds). A few passages could be trimmed: the attribution paragraph duplicates the frontmatter, and the aside about the timing script's donation/award origins plus the permutation-test statistics explanation restates context Claude already knows. Efficient overall with minor over-explanation, matching the level-4 anchor rather than 'every token earns its place'.

Actionability

Nearly all guidance is copy-paste ready with realistic values (`--cik 0000320193 --types 10-K,10-Q`, `--jurisdiction us_ny`, documented output columns and idempotency), and every referenced script exists. Two minor gaps hold it below fully executable: the 'Adding a new data source' section's `cp SKILL_DIR/templates/source-template.md` command targets a file that does not exist in the bundle, and `SKILL_DIR` is a placeholder the agent must substitute before any command runs.

Workflow Clarity

A clearly numbered 1-5 pipeline (identify sources → acquire → resolve entities → optional timing test → build findings) with explicit validation and feedback loops: fetchers "return 0 rows with a clear warning rather than silently writing an empty CSV", scripts "surface 429 responses immediately with the upstream's quota message", EDGAR flags individual-filer mismatches, and step 5 produces evidence where "[e]ach evidence item points back to a specific row in a source CSV". The 'Confidence and evidence discipline' section supplies the checklist. This matches the anchor with explicit validation steps, error-recovery feedback, and a checklist; operations are read-only so no destructive-operation cap applies.

Progressive Disclosure

Textbook structure: an explicit `ls`/`cat` listing signals the per-source reference files, all 11 exist and follow the claimed 9-section template, details are exactly one level deep, and per-source schema/coverage/legal content is correctly kept out of SKILL.md. One real defect found against the actual bundle: `SKILL_DIR/templates/source-template.md` is referenced in the body but no `templates/` directory exists, leaving one broken navigation path. That single gap places it just below the clear-overview anchor.

Specificity

The description names its domains ("public records and sanctions data") but its only action is the idiom "Follow the money", which is a slogan rather than a concrete action. It does not list 1-2 concrete operations (e.g., "screens entities against sanctions lists", "resolves corporate names across registries"), so it sits at the 'names the domain, generic action' anchor rather than the level above.

Completeness

Per the guideline, the missing 'Use when...' clause caps completeness at 3. A 'what' is present (following money flows via public records and sanctions data) but it is thin — one idiomatic action plus two domains — and 'when' is entirely absent, so it does not reach the both-present level.

Trigger Term Quality

It has some genuinely natural terms ("follow the money", "public records", "sanctions") but only three keyword phrases for a skill spanning 11 sources. Common variations a user would actually say — due diligence, lobbying, OFAC, corporate filings, court records, offshore leaks, entity resolution, OSINT — are all missing, matching the 'relevant keywords but missing common variations' anchor rather than good coverage.

Distinctiveness Conflict Risk

"Public records and sanctions data" plus "follow the money" carves a fairly distinct investigative niche unlikely to trigger for unrelated skills, with only minor overlap risk against general web-research or due-diligence requests. Not 5 because without fuller trigger phrasing, a generic 'research this company' ask could plausibly route here over a general research skill.
