Conciseness

The body is imperative and procedural with no explanations of concepts Claude already knows, but the 'increment version' rule is repeated across MoviePilot-Specific Rules, Step 4, Step 7, Step 8, the Minimal Example, and the Final Checklist. This matches anchor 4 ('minor instances of over-explanation that could be trimmed') rather than 5, and is above 3 because the excess is redundancy, not conceptual padding.

Actionability

Guidance is fully executable for an instruction-only skill: concrete paths (skills/<skill-id>/SKILL.md), a copy-paste-ready frontmatter template, concrete naming rules with worked ID examples (transfer-failed-retry, moviepilot-api), and a worked user-request example with expected outcome. Matches anchor 5; the only soft spot ('If possible, validate the file can be parsed by the MoviePilot skills loader') is minor against the common cases covered.

Workflow Clarity

Eight clearly sequenced steps with an explicit validation checkpoint in Step 8 (name matches directory, description has real triggers, version increased), a Final Checklist, and an ambiguity checkpoint in Step 1. This matches anchor 5 ('explicit validation steps; feedback loops; checklists for complex processes'); it is above 4 because checkpoints and a checklist are explicitly present, not implicit.

Progressive Disclosure

Sections are well organized and easy to navigate, no references point to nonexistent files (the skill is a single SKILL.md with no bundle directories, and the body correctly advises staying single-file for instructions-only skills). However, the body exceeds 50 lines so the simple-skill exception does not strictly apply, and there is no overview-to-detail split — matching anchor 4 rather than 5.

Specificity

The description enumerates multiple concrete actions — 'create, scaffold, update, or review', 'adding a new built-in skill under the repository skills/ directory', 'writing SKILL.md frontmatter', 'choosing allowed-tools', 'adding helper scripts', 'bumping the built-in skill version' — giving comprehensive coverage of the skill's domain. It exceeds anchor 4 because there are no meaningful coverage gaps within its niche.

Completeness

It explicitly answers 'when' ('Use this skill when the user asks to create, scaffold, update, or review a MoviePilot agent skill') and 'what' (a full enumeration of the sub-tasks involved), with concrete trigger phrases. This matches anchor 5 rather than 4 because the when-clause is explicit and specific, not merely present.

Trigger Term Quality

Natural trigger terms are well covered ('create', 'scaffold', 'update', 'review', 'MoviePilot agent skill', 'built-in skill', 'SKILL.md', 'allowed-tools', 'version'), matching the phrasing a user would actually say when requesting skill creation. It falls short of anchor 5 because a few natural synonyms and phrasings (e.g., 'add a skill to MoviePilot', non-English requests) are not covered.

Distinctiveness Conflict Risk

The niche is unambiguous and consistently qualified — MoviePilot repository built-in skills, the skills/ source of truth, and syncing into config/agent/skills — so it is clearly distinguishable from generic skill-creation or document skills. Clear niche with distinct triggers and minimal conflict risk, matching anchor 5.
