Conciseness

Every phrase changes behavior — "Start it with a fresh context window", "a single Markdown file", "citing each claim's source", "match the existing convention" — with zero padding and no explanation of concepts Claude already knows. This matches the lean, every-token-earns-its-place anchor.

Actionability

For an instruction-only skill the guidance is concrete and directive: spin up a background agent, investigate primary sources enumerated as "official docs, source code, specs, first-party APIs", write one Markdown file with per-claim citations, and place it per repo convention with an explicit fallback. It falls just short of anchor 5 because no example of the findings-file structure or citation format covers the common case.

Workflow Clarity

The sequence is clear and unambiguous — spin up the agent, then a numbered job spec — and includes an explicit decision branch ("if there is none, put it somewhere sensible and say where"). This is a single-purpose, non-destructive task, so the simple-skill exception applies and no validation checkpoint is required.

Progressive Disclosure

The skill is under 50 lines, needs no external references, and no bundle files exist — the body is well organized into a setup line, a job header, and a numbered list. Per the simple-skill guideline, this earns the top score without external file references.

Specificity

Lists two concrete actions — "Investigate a question against high-trust primary sources" and "capture the findings as a Markdown file in the repo" (with output format and location specified). This matches the anchor for 1-2 concrete actions; it falls short of anchor 4, which requires several specific actions, and is clearly above anchor 2's generic actions.

Completeness

Explicitly answers both: what ("Investigate a question against high-trust primary sources and capture the findings as a Markdown file in the repo") and when ("Use when the user wants a topic researched, docs or API facts gathered, or reading legwork delegated to a background agent") with concrete trigger phrases. This matches the anchor-5 example pattern; anchor 4's weaker 'when' clause does not apply.

Trigger Term Quality

Natural phrases users would say are present: "a topic researched", "docs or API facts gathered", "reading legwork delegated". Good coverage, but common variations like "look up", "find out about", or "check the documentation" are missing, so it does not reach comprehensive anchor 5.

Distinctiveness Conflict Risk

The niche — delegated primary-source research captured as a repo Markdown note — is mostly distinct with specific triggers. Minor overlap risk remains with generic web-search or documentation-lookup skills on broad terms like "research" and "docs", keeping it below anchor 5 but well above anchor 3.
