Conciseness

The body is dense and imperative with no explanation of concepts Claude already knows — steps like "Record: tool name, author/org, license, language, latest version/commit" and tight section bullets assume competence. Minor trimming opportunities remain: the duplicate-check instruction appears three times (Workflow step 2, Quick Commands, and an anti-pattern), and the trailing table-format comment in Quick Commands duplicates step 7. Not a 5 because of that small redundancy; well above the padded 3 anchor.

Actionability

Mostly executable guidance: concrete commands (`grep -i "<slug>" REVIEWED.md references/REFERENCE_INDEX.md`, `git submodule add <repo-url> tools/<repo-name>`, `./scripts/validate-reference-tool.sh references/<slug>.md`), exact file templates, and a literal table row format. The gap keeping it from 5: `cp templates/REFERENCE-tool.md references/<slug>.md` references a non-existent path (the real template is `assets/templates/REFERENCE-tool.yaml`), and the workflow steps defer some specifics (e.g., running the validator after step 5) rather than stating them inline.

Workflow Clarity

Ten numbered steps in a coherent order with real checkpoints: step 2's duplicate check with "If already present, report it and stop", explicit user-confirmation gates before vendoring (step 6) and promotion (steps 9-10), and schema validators for outputs. A 5 would embed the validation scripts directly into the workflow steps (e.g., "run validate-reference-tool.sh after step 5") with an explicit fix-and-retry loop rather than leaving them in Quick Commands.

Progressive Disclosure

Clear overview with well-signaled, one-level-deep references that all exist on disk: [classification guide](references/classification-guide.md) for taxonomy, `assets/templates/*.yaml` for field structures, `assets/schemas/*.schema.json`, and the two validator scripts — each deferred detail lives in exactly one bundle file and is linked with its purpose. The body holds only workflow-level guidance, matching the 5 anchor's structure.

Specificity

"Creates references/{slug}.md with architecture overview and scope assessment; adds REVIEWED.md entry and REFERENCE_INDEX.md row" lists several concrete, verifiable actions with named deliverables. Not a 5 because the action list covers only the core triage outputs — promotion to ANALYSIS-*.md and vendoring steps from the body are absent, a minor coverage gap.

Completeness

It explicitly answers both questions: what ("Triage a tool or library into a structured reference summary... Creates references/{slug}.md... adds REVIEWED.md entry") and when ("Use when given a GitHub URL, npm package, PyPI package, or CLI tool name" plus an explicit Triggers list with concrete phrases). This matches the 5-anchor example structure of a what-clause followed by an explicit when-clause with trigger phrases.

Trigger Term Quality

"Triggers: triage tool, add tool, analyse tool, GitHub project, npm package, PyPI package, library, framework, CLI tool, MCP server, open source project" plus "Use when given a GitHub URL, npm package, PyPI package, or CLI tool name" gives comprehensive natural-term coverage including synonyms (tool/library/framework/project) and artifact types. A 4 would require noticeably missing common terms, and the only marginal omission ('analyze' vs 'analyse' spelling) does not rise to that.

Distinctiveness Conflict Risk

"Triage a tool... into a structured reference summary for the research repo" carves a clear niche with distinct action verbs (triage/add to repo). Broad trigger terms like "library, framework, open source project, MCP server" create minor overlap risk with general research or evaluation skills, keeping it below the minimal-conflict 5 anchor.
