Conciseness

The body is lean and direct — executable commands, minimal prose, no explaining of what markdown is or how libraries work — and lines like "Relative paths resolve against the caller's cwd and `~` expands" earn their place. Matches the anchor for lean, efficient content that assumes Claude's competence. Not 4 because there is no over-explanation to trim.

Actionability

Three concrete executable commands with real flags (--workspace/--surface/--window) plus a copy-paste-ready AGENTS.md snippet give fully executable, common-case coverage. Matches the anchor for copy-paste-ready commands covering common cases. Not 4 because the examples cover the common cases with specific, working flags.

Workflow Clarity

As a single-purpose skill (open a .md file), the workflow is unambiguous with a meaningful pre-step ("Write the full plan file first, then open it, so the panel never shows a partially written file") and clear post-open guidance (overwrite/append freely triggers re-render). The simple-skill exception applies; no destructive/batch validation cap is relevant. Not 4 because the single action is unambiguous with a real pre-step.

Progressive Disclosure

The body is a clear overview with a "Deep-dive references" table pointing to two real, one-level-deep files (references/commands.md and references/live-reload.md), each clearly signaled with a "When to Use" column; bulk command syntax and reload internals are correctly split out into those files. Matches the anchor for a clear overview with well-signaled one-level-deep references. Not 4 because navigation is clean and references are genuinely one level deep (verified the files exist and contain the deferred detail).

Specificity

"Open markdown files in a formatted viewer panel with live reload" names one concrete action with rendering detail (headings, code blocks, tables, lists), matching the anchor that names the domain and 1-2 concrete actions but isn't comprehensive. Not 4 because the action set is narrow (just "open") and the rest is rendering detail rather than distinct actions.

Completeness

It explicitly answers both what ("Open markdown files in a formatted viewer panel with live reload") and when ("Use when you need to display plans, documentation, or notes alongside the terminal with rich rendering"), with concrete trigger phrases. Not 4 because the trigger guidance is concrete and explicit rather than weakly implied.

Trigger Term Quality

Natural trigger phrases users would say — "plans, documentation, or notes alongside the terminal" plus "markdown files" — give good keyword coverage, matching the anchor for good coverage with a few natural terms missing. Not 5 because it lacks file-extension synonyms like ".md" and variants like "docs" or "README".

Distinctiveness Conflict Risk

The cmux markdown viewer panel alongside the terminal is a clear, narrow niche with distinct triggers (plans/docs/notes alongside terminal), giving minimal conflict risk with other skills. Not 4 because the triggers are specific enough to avoid firing for unrelated skills.
