Skills
Platform expansion packs and custom skills that gate tool bundles.
Skills extend agents with bundled tools and prompts. Platform expansion skills (for example find_skills, frontend_design) ship in the catalog; orgs enable them per agent from /<orgSlug>/skills or the agent detail page.
Disabling a skill removes its exclusive tools from the runtime filter while leaving overlapping built-in tools available.
Mutations require a browser session with step-up — see Skills API.
