+# Story 229: Coder agents should check off acceptance criteria as they fulfill them
+
+## User Story
+
+As a user watching agent progress, I want coder agents to check off acceptance criteria in the story file as they write tests and code to fulfill them, so that I can see real-time progress on the story without reading agent logs.
+
+## Acceptance Criteria
+
+- [ ] Coder agent prompt instructs the agent to use the check_criterion MCP tool after fulfilling each acceptance criterion
+- [ ] Acceptance criteria are checked off individually as work progresses, not all at once at the end
+- [ ] The agent reads the story's acceptance criteria at the start of work via get_story_todos
+- [ ] Checked-off criteria are visible in the web UI pipeline board in real time
+
+## Out of Scope
+
+- TBD
