Conciseness

Largely lean and prescriptive — mode-routing tables, argument tables, numbered phases, and one-liner anti-patterns rather than concept tutorials — but there is duplication: the init hard rules reappear in the Definition of Done checklists, the mode table plus the disambiguation list state the routing twice, and Core Principles restate routing rationale already given in mode sections. Not 5: these repeated blocks are tokens that could be trimmed; not 3: the padding is minor and the tone consistently assumes Claude's competence (e.g., no explanation of what git or markdown is).

Actionability

Some concrete guidance exists in-body — "CLAUDE.md ≤ 200 lines", "ln -s CLAUDE.md AGENTS.md", badge-count limits, AskUserQuestion options, dry-run flag, P0/P1/P2 tiers — but the executable meat of every mode is deferred to files that are not in the bundle: "see rules/drift-detection.md §1 for git diff commands", the Content Routing Rubric, the Placement Resolver algorithm, the mandatory README section order, and all templates/*.md skeletons are all missing. Not 4: the gaps are not minor — a run of any mode would stall at the first "load rules/X.md" instruction; not 2: the body still delivers specific routing, budgets, and gates that can be acted on alone.

Workflow Clarity

Each mode has a numbered phase sequence with checkpoints: init gates on AskUserQuestion before overwriting, update offers dry-run and asks confirmation for P1 items, audit is declared read-only, and every mode closes with a Definition of Done checklist ("Treat any unchecked item as a defect") including verification items like "Every @import added resolves to a real file" and "Every relative link resolves". Not 5: several checkpoints are implicit or underspecified in-body (drift-detection commands, README rubric scoring procedure) because the detail lives in absent rule files; not 3: explicit checklists and confirmation gates are present for the batch-write update flow, so the destructive/batch cap does not apply.

Progressive Disclosure

Scored against the actual bundle: the body declares itself "a thin index" pointing to rules/*.md (9 referenced files) and templates/*.md, but neither directory exists — only references/archetypes.md is present, so ~10 of 11 referenced paths are broken, and references/research-sources.md exists yet is never linked from the body. Not 3: the in-body structure and reference signaling are excellent on paper, but navigation to any detailed material is dead, and one bundled file is undiscoverable; not 1: the body itself is well-sectioned and contains substantial standalone guidance rather than being unnavigable.

Specificity

Multiple specific concrete actions per mode: "init scaffolds a tiered docs setup", "update detects drift (dead @imports, renamed commands, stale narrative) and incrementally refreshes via a Placement Resolver", "readme writes or audits a README against the standard-readme spec", "audit produces a documentation health report" — comprehensive coverage across all four modes with named targets. Not 4: no meaningful gap in action coverage; every mode's capability is stated concretely rather than generically.

Completeness

Explicitly answers both questions: what ("Authors, audits, and maintains project documentation across CLAUDE.md / .claude/rules/, AGENTS.md, README.md, and Diátaxis docs/ trees", plus per-mode capabilities and routing rules) and when ("Triggers on 'init claude', 'bootstrap docs', …"). Not 4: the 'when' is not merely present but enumerated with concrete trigger phrases, matching the anchor-5 example pattern exactly.

Trigger Term Quality

Comprehensive natural trigger phrases with synonym variations: "init claude", "bootstrap docs", "scaffold CLAUDE.md", "update docs", "sync CLAUDE.md", "docs drift", "write a README", "audit our docs", "review the README", "Diátaxis", "/docs". Not 4: coverage includes both verb-form and noun-form phrasings users would naturally say, plus the slash-command form; nothing obvious is missing.

Distinctiveness Conflict Risk

Clear niche — agent-facing docs architecture (CLAUDE.md tiering, .claude/rules/ placement, Diátaxis docs trees) — with distinctive triggers like "sync CLAUDE.md", "scaffold CLAUDE.md", and "Diátaxis" that no generic documentation or README skill would claim. Not 4: overlap risk is minimal; even the broadest trigger ("write a README") is disambiguated by the surrounding spec-based readme mode context.
