CLI and MCP

Where in the UI. From a git checkout of the template editor. Live mode talks to an already running yarn dev.

If you have the editor sources:

yarn containd-author --help
yarn containd-author-mcp

File mode: pass --project path.json. Live mode: omit project, probe get_session / yarn containd-author live-session. Never start a second Vite server — that mints a new hub and drops the user’s session. Confirm still happens in the editor chat UI.

Packed prompts: packs/containd-author-v1/, skill skills/containd-author/SKILL.md, Blockly API docs/planning/EDITOR_SCRIPT_BLOCK_API.md. After adding recipes or help docs: yarn generate:agent-assets.

MCP tools include export_context, validate, smoke, advise, apply_plan, propose_*, recipes, describe_blocks, compose_script, translate_workspace, layout_describe, retrieve_docs, live_*.
