Conciseness

The 18-line body is lean and assumes Claude's competence: every line instructs (tool names, dispatch rules, confirmation policy) and nothing explains concepts Claude already knows. The note that 'retired command tools and MCP aliases do not exist' is genuinely non-obvious information, not padding.

Actionability

Concrete, executable guidance throughout: exact tools (slash.list, slash.run, plugin.capabilities), the exact request field ('body.command containing the complete command'), and a specific example ('/sites disable 3'). Not 5 because no complete request/response example is shown; not 3 because the commands named are real and directly invokable, not pseudocode.

Workflow Clarity

Steps 1-5 form a clear sequence with explicit checkpoints: no-match reporting ('If the live catalog has no match, report that no supported command was found'), confirmation for state-changing execution, and post-dispatch validation ('Check the returned acceptance/result before reporting completion'). Validation is present so the destructive-operation cap at 3 does not apply, but there is no error-recovery feedback loop (what to do on a failed run), keeping it below anchor 5.

Progressive Disclosure

The skill is under 50 lines, single-purpose, needs no external references (none exist in the bundle), and is well organized as a numbered procedure plus a closing note on authoritative sources. This matches the simple-skill exception: well-organized sections alone warrant the top score.

Specificity

Three concrete actions are named ('Discover the live command catalog', 'resolve the exact command', 'dispatch it through the structured API gateway'), giving solid coverage with only a minor gap (result verification is not mentioned). Not 5 because coverage is not fully comprehensive; not 3 because multiple specific actions are listed rather than just 1-2.

Completeness

Both 'what' (discover catalog, resolve exact command, dispatch via the API gateway) and 'when' are explicitly stated with concrete trigger phrases ('when the user sends a slash command or asks to run a MoviePilot system or plugin command in natural language'). Clearly matches the top anchor rather than anchor 4, where 'when' is only adequate.

Trigger Term Quality

Natural phrases a user would say are present ('sends a slash command', 'asks to run a MoviePilot system or plugin command in natural language'). A few natural variations are missing (e.g., 'execute a command', concrete command names like restart or site sync), keeping it below the comprehensive anchor.

Distinctiveness Conflict Risk

The description is anchored to a clear niche (MoviePilot slash/plugin commands via the structured API gateway) with distinct triggers, so it is unlikely to fire for the wrong skill. Distinctly better than the 'minor overlap risk with closely related skills' anchor 4.
