+# PM Bot Repository Cleanup
+
+## Overview
+Successfully removed all old Slack AI chatbot features to focus exclusively on PM Bot functionality for Jira/GitHub ticket management.
+
+## Files Removed (15 files, ~462 lines)
+
+### 1. User State Management (`state_store/`)
+- `__init__.py`
+- `file_state_store.py` - File-based storage for user preferences
+- `get_user_state.py` - Retrieve user's AI provider selection
+- `set_user_state.py` - Save user's AI provider selection
+- `user_identity.py` - User object definition
+- `user_state_store.py` - Base class for state storage
+
+**Why removed:** PM Bot doesn't need to remember per-user AI provider preferences
+
+### 2. Interactive Actions (`listeners/actions/`)
+- `__init__.py`
+- `set_user_selection.py` - Handle AI provider selection from app home
+
+**Why removed:** No app home or user selection needed for PM Bot
+
+### 3. Slash Commands (`listeners/commands/`)
+- `__init__.py`
+- `ask_command.py` - `/ask-pmbot` command handler
+
+**Why removed:** PM Bot works via mentions and DMs, not slash commands
+
+### 4. Workflow Functions (`listeners/functions/`)
+- `__init__.py`
+- `summary_function.py` - Channel summarization for Workflow Builder
+
+**Why removed:** Not part of PM Bot's ticket management purpose
+
+### 5. App Home (`listeners/events/`)
+- `app_home_opened.py` - Display AI provider selection UI
+
+**Why removed:** PM Bot doesn't use app home
+
+### 6. Other Files
+- `app_oauth.py` - OAuth flow for multi-workspace distribution
+- `slack.json` - Unknown config file
+
+**Why removed:** Not currently needed for PM Bot
+
+## Files Updated (6 files)
+
+### 1. `manifest.json`
+- Removed `app_home` configuration
+- Removed `slash_commands` section
+- Removed `summary_function` definition
+- Removed `app_home_opened` and `function_executed` events
+- Disabled `interactivity` (was only for app home actions)
+- Removed `commands` from bot scopes
+
+### 2. `ai/providers/__init__.py`
+- Removed dependency on `state_store.get_user_state`
+- Added `_get_default_provider()` function
+- Auto-detects AI provider from environment variables (priority: Anthropic > OpenAI > Vertex)
+- Simplified `get_provider_response()` to use default provider
+
+### 3. `listeners/__init__.py`
+- Removed imports for `actions`, `commands`, `functions`
+- Only registers `events` now
+
+### 4. `listeners/events/__init__.py`
+- Removed import for `app_home_opened_callback`
+- Removed registration of `app_home_opened` event
+
+### 5. `listeners/listener_utils/listener_constants.py`
+- Removed `SUMMARIZE_CHANNEL_WORKFLOW` constant
+- Updated comments to reflect PM Bot usage
+
+### 6. `README.md`
+- Removed reference to `/ask-pmbot` slash command
+
+## What Remains
+
+### Core PM Bot Functionality
+- `mcp/` - Jira and GitHub MCP integration (5 files)
+- `listeners/events/app_mentioned.py` - Handle @pmbot mentions
+- `listeners/events/app_messaged.py` - Handle DMs to pmbot
+- `listeners/listener_utils/pmbot_utils.py` - Shared PM Bot utilities
+- `ai/` - AI providers for fallback responses (6 files)
+- `tests/` - Comprehensive test suite (3 files, 30 tests)
