Update a skill

⚠️
Preview — this feature is being built; the design below is the spec.
PATCH https://app.syntic.ai/v1/skills/{skill_id}

Change a skill’s display title or which version latest points at. Pinning latest to an older version is how you roll back without deleting the newer one; agents and requests that reference latest pick it up on their next turn.

For how this fits into a full workflow, see Agent skills.
