beam

Use when starting Phase 1 of the Beam workflow, or when a new repository needs a `plan.md` before any scaffolding, AGENTS.md, or technical spec work begins.

Use when `plan.md` exists at the repository root but either `collab_progress/` or `README.md` is missing, or when the user asks to scaffold a new repository for agent-driven development.

Use when the user asks to initialize a new repository for agent-driven development, bootstrap a project harness, or set up a fresh repo for collaborative work with coding agents.

Use when beginning Phase 3 of the Beam workflow, or when a repository has a `plan.md` and `collab_progress/` but no `AGENTS.md` at the root (or the user asks to author or refresh `AGENTS.md`).

Use when beginning Phase 4 of the Beam workflow, or when the user asks for a technical specification, design doc, SPEC.md, docs/SPEC.md, architecture doc, or "spec the system" for a repository.
