+# Story 331: Bot start command to start a coder on a story
+
+## User Story
+
+As a project owner in a chat room, I want to type "{bot_name} start {story_number}" to start a coder on a story, so that I can kick off work without needing the MCP tools or web UI.
+
+## Acceptance Criteria
+
+- [ ] '{bot_name} start {number}' finds the story and starts the default coder agent on it
+- [ ] '{bot_name} start {number} opus' starts coder-opus specifically
+- [ ] Returns confirmation with agent name and story title
+- [ ] Returns error if story not found or all coders busy
+- [ ] Moves story from backlog to current if needed
+- [ ] Registered in the command registry so it appears in help output
+- [ ] Handled at bot level without LLM invocation
+
+## Out of Scope
+
+- TBD
