Conciseness

The body is lean and assumes competence — no explaining what MDX or a repo is, no library-choice digressions, and every section carries operational weight (commands, targets, block types, privacy rules). It is not 5 because the opening paragraph partially restates the description and the six 'Useful variants' plus the multi-line --target example could be trimmed slightly; it is well above 3 since there is no genuinely unnecessary explanation.

Actionability

Every command is copy-paste executable ('npx @agent-native/core@latest visualize-repo --open', 'init', 'check', 'verify', '--target' variants), and the guidance names concrete artifacts ('api-endpoint', 'data-model', 'wireframe', 'diagram', 'annotated-code') and concrete files ('agent-native.json', 'comments.json', '.agent-native/visual-docs/repo-overview'). This matches the fully-executable, common-cases-covered anchor; nothing is pseudocode or vague.

Workflow Clarity

The 'Agent Workflow' is a clear five-step sequence with explicit validation checkpoints (step 4 'Run visualize-repo check after editing MDX', step 5 'Use verify before handoff when renderer correctness matters') plus a comments feedback path. It falls short of 5 because there is no error-recovery loop (what to do when 'check' or 'verify' fails — fix and re-run is never stated), which the anchor-5 example requires; it is above 3 since validation steps are explicit rather than implicit.

Progressive Disclosure

This is a single-file skill with no references/, scripts/, or assets/ directories, so there is nothing to disclose progressively; the ~80-line body is entirely appropriate to keep inline and is organized into clear, navigable sections (Default Command, No Manifest, Agent Workflow, Privacy Boundary) with no buried or nested references. Per the rubric's simple-skill guidance this well-organized single-file structure earns the top score; there is no monolithic reference dump or nested 'see X' chain that would lower it.

Specificity

The description names the domain ("repo-native visual documentation workspace backed by local Plan MDX files") and only two actions ("Open or create"), which matches the anchor for 1-2 concrete actions without comprehensive coverage. It is not a 4 because it does not list several distinct actions (e.g., generating wireframes, API specs, or schema views — those appear only in the body), and it is clearly above 2 since the domain and actions are concrete rather than generic.

Completeness

It explicitly answers both questions: what ("Open or create a repo-native visual documentation workspace backed by local Plan MDX files") and when ("Use when the user asks to visualize a repository, create durable visual docs..., launch a visual repo viewer, review repo docs like a visual IDE, or collect Plan comments...") with multiple concrete trigger phrases. This mirrors the anchor-5 example structure (what + explicit 'Use when' with concrete triggers), not the weaker or less explicit 'when' of anchor 4.

Trigger Term Quality

Trigger phrases like "visualize a repository", "create durable visual docs for APIs/components/models/flows", "launch a visual repo viewer", and "review repo docs like a visual IDE" give good natural keyword coverage a user would plausibly say. It falls short of 5 because it lacks synonyms and file-extension triggers (e.g., no mention of MDX files as a trigger or common alternates like 'repo map' / 'architecture diagram'), and it is well above 3's 'some relevant keywords but missing common variations'.

Distinctiveness Conflict Risk

Triggers like "visualize a repository", "visual repo viewer", and "Plan comments that should become coding-agent changes" carve a fairly distinct niche with domain-specific terms (Plan, agent-native), making wrong-skill triggering unlikely. It is not 5 because 'create visual docs' has some residual overlap with general documentation/visualization skills, but it is well above 3 since the specific triggers disambiguate it from close neighbors.
