Conciseness

The body is lean and imperative — numbered steps, exact file paths, one complete code template, and no explanation of concepts Claude already knows (no preamble about what Remotion or CLI parsing is). Every token earns its place, matching anchor 5 rather than anchor 4, which would require some trimmable over-explanation.

Actionability

Guidance is fully executable: a copy-paste-ready `satisfies AnyRemotionOption<boolean>` template, exact file paths (`packages/cli/src/parsed-cli.ts`), precise type snippets (`[myFlagOption.cliFlag]: TypeOfOption<typeof myFlagOption>`), and concrete build commands (`bun run make`). It matches anchor 5; nothing is pseudocode or left abstract.

Workflow Clarity

Steps 1–7 are clearly sequenced, the docs step is flagged as mandatory ("IMPORTANT, do not skip this step"), and step 7 provides a build/verify checkpoint. It falls short of anchor 5 because there is no error-recovery feedback loop (e.g. what to do when `bun run make` fails or how to check the docs render), only a terminal verify step — anchor 4's 'most checkpoints present; minor validation gaps'.

Progressive Disclosure

A single-file skill with no bundle directories (references/, scripts/, assets/ absent) and well-organized numbered sections; the one external pointer (`../studio-config-option-lifecycle/SKILL.md`) is clearly signaled, conditionally scoped ('If the option is consumed by Studio'), and one level deep, and the closing 'Reference files' list points directly at repo paths. It matches anchor 5's clear overview with well-signaled one-level-deep references; it is not anchor 4 because no content is misplaced or buried.

Specificity

The description enumerates concrete actions — "creating an AnyRemotionOption, registering CLI parsing, wiring config setters, and updating documentation" — giving comprehensive coverage of the workflow's phases, matching the top anchor's multiple specific concrete actions. It is not score 4 because the action list covers every major step of the task with no minor gaps, and not below because there is no vague or generic language.

Completeness

Explicitly answers both: what — the four concrete actions — and when — "Use when adding or converting command-line flags or Remotion options", with concrete trigger phrases. It clearly matches anchor 5 rather than anchor 4 because the 'when' clause is explicit and specific, not merely present.

Trigger Term Quality

Strong natural terms users would say: "Remotion CLI", "config option", "command-line flags", "Remotion options", "adding or converting". It falls just short of anchor 5 because common synonyms like "CLI argument" or phrasings like "add a flag" variants are absent, matching anchor 4's 'good keyword coverage; a few natural terms missing' rather than comprehensive synonym coverage.

Distinctiveness Conflict Risk

The Remotion-specific vocabulary ("Remotion CLI or config option", "AnyRemotionOption") carves out a clear niche with distinct triggers and minimal conflict risk with other skills. It matches anchor 5; it is not anchor 4 because the trigger terms are domain-unique rather than overlapping with closely related generic skills.
