Conciseness

Every line is an operational constraint or command — e.g. "Maximums include the root: 60 nodes, depth 6, 120 characters per label" and "The Markdown argument must be byte-for-byte the verified source; do not summarize it". There are no concept explanations Claude already knows and no padded sections; the only near-redundancy (two sentences on appearance ownership) is a justified guardrail, so this matches the 'lean and efficient; every token earns its place' anchor.

Actionability

The body gives the exact render command (`node /opt/remotion/render-mindmap.mjs /workspace/<slug>.md /workspace/<slug>.png`), complete copy-paste-ready `verify_artifact` and `save_artifact` call templates with all parameters, and exact output specs ("an exact 2400×1600 PNG"). This matches 'fully executable; copy-paste ready code or commands'.

Workflow Clarity

The author → render → verify → save sequence is explicit, with a validation checkpoint (`verify_artifact`), a feedback loop ("Fix all blocking findings together, rerender once, and reverify both exact paths"), a stop condition ("If a blocker remains, stop and explain it instead of looping"), and a defined revision workflow. This matches the anchor with explicit validation steps and error-recovery loops.

Progressive Disclosure

This is a single-purpose skill with three well-organized sections (Content contract, Render, Verify and save); no bundle files exist (references/, scripts/, assets/ are absent) and none are needed, as all content is short and belongs inline. Per the simple-skill guidance, well-organized sections with no need for external references satisfy the top anchor.

Specificity

The description names the domain ("hierarchical mind maps") and two concrete actions ("Create... as canonical Markdown", "with a static PNG download"), which matches the '1-2 concrete actions but not comprehensive' anchor. It does not reach 4 because it omits capabilities the body actually has (rendering, verification, revision handling); it stays above 2 because the actions it does list are concrete rather than generic.

Completeness

The 'what' is clear ("Create concise hierarchical mind maps as canonical Markdown with a static PNG download"), but there is no 'Use when...' clause or equivalent trigger guidance, so 'when' is only weakly implied. Per the judging guidelines, a missing 'Use when...' clause caps completeness at 3.

Trigger Term Quality

"mind maps" is the natural phrase a user would say, reinforced by "hierarchical", "Markdown", and "PNG" — good keyword coverage. It falls short of 5 because there are no synonyms or variations ("mindmap", "concept map", "tree diagram", "outline"), leaving a few natural terms missing.

Distinctiveness Conflict Risk

"mind maps" establishes a mostly distinct niche unlikely to trigger generic document or file skills. Minor overlap risk remains with diagramming/visualization skills via the broad terms "Markdown" and "PNG", which keeps it below the 'clear niche with minimal conflict' anchor at 5.
