Ca New Skill

/ca-new-skill — author a skill

The only permitted entry to creating a skill. Nothing is written until the gap is proven uncovered — skills are not created speculatively. Name the skill in verb-noun form ("dependency-review"), not as a description ("the thing that checks packages").

Flow

Routes to the skill-author skill, which owns the work end to end through its five gated phases — gap

evidence, scope, authoring, self-review against the v2 house style, and routing integration (the

INDEX.md + routing-table entry that makes the new skill reachable). The phase definitions live in the

skill; this command does not restate them. Nothing is authored until an existing skill or agent is

proven not to cover the need; nothing ships until the new skill carries gated phases, hard rules, and

its routing entry.

Routes to

skill-author (<plugin-root>/routines/skill-author/SKILL.md) — all five phases.

When NOT to use

• A one-time action → /ca-feature or a command definition.
• An existing skill nearly covers it → extend that skill via /ca-feature.
• "Do we even need a skill here?" → /ca-btw.

Hard gate

MUST prove the gap is real in Phase 1 before writing any skill content. MUST get user approval on the

spec before authoring. MUST NOT create a skill that duplicates an existing skill's purpose — surface

the overlap instead. Skill files live only under <plugin-root>/routines/<name>/.
