+# Story 50: Unified Current Work Directory
+
+## User Story
+
+As a developer, I want a single `.story_kit/current/` directory (outside of `stories/`) that holds whatever work items agents are actively working on — stories, bugs, or spikes — so I can always see at a glance what coders are doing.
+
+## Acceptance Criteria
+
+- [ ] New top-level `.story_kit/current/` directory replaces `.story_kit/stories/current/`
+- [ ] `start_agent` moves work items into `.story_kit/current/` regardless of type (story, bug, spike)
+- [ ] `accept_story` moves from `.story_kit/current/` to `.story_kit/stories/archived/`
+- [ ] `close_bug` moves from `.story_kit/current/` to `.story_kit/bugs/archive/`
+- [ ] All existing references to `.story_kit/stories/current/` are updated (server code, tests, MCP tools)
+- [ ] Migrate any files currently in `.story_kit/stories/current/` to `.story_kit/current/`
+- [ ] Auto-commits use deterministic messages for all moves
+
+## Out of Scope
+
+- Spike lifecycle (create/archive) — can follow later
+- UI changes to display current work items
