Skills
Agent-loaded procedures ship with the distro: AGENTS.md is a short role bootstrap every session loads, COORDINATOR.md is the coordinator core init names, and each action's detail stays in the bundled skills, loaded only for that action.
Factory lane
A factory lane (sumctl factory plus the factory procedures in sum-dispatch and the worker procedure) can run sequential ready issues on an enrolled project without a sum daemon: tick is a one-shot helper, dispatch stays with the coordinator, and merge happens only at high confidence on authorized repositories.
Third-party skills
Delegates explicit skill and agent selections to the pinned Vercel Skills CLI in project copy mode. Skills reach agents as explicit file references (path, size, hash) to read when needed, not as an assumed skill standard. See docs/sum-skills.md ↗.
Verification authoring skills
.agents/skills/create-verification inspects a repository, scaffolds its contract, verify task, seed feature maps, and vendored skills without inventing commands, then proves them once; .agents/skills/maintain-verification audits stale tasks, paths, links, and coverage claims. Both work in any clone.
