+# Fix for Conversation History Bug in Continuation Flow
+
+## Problem
+When using `continuation_id` to continue a conversation, the conversation history (with embedded files) was being lost for tools that don't have a `prompt` field. Only new file content was being passed to the tool, resulting in minimal content (e.g., 322 chars for just a NOTE about files already in history).
+
+## Root Cause
+1. `reconstruct_thread_context()` builds conversation history and stores it in `arguments["prompt"]`
+2. Different tools use different field names for user input:
+   - `chat` → `prompt`
+   - `analyze` → `question`
+   - `debug` → `error_description`
+   - `codereview` → `context`
+   - `thinkdeep` → `current_analysis`
+   - `precommit` → `original_request`
+3. The enhanced prompt with conversation history was being placed in the wrong field
+4. Tools would only see their new input, not the conversation history
+
+## Solution
+Modified `reconstruct_thread_context()` in `server.py` to:
+1. Create a mapping of tool names to their primary input fields
+2. Extract the user's new input from the correct field based on the tool
+3. Store the enhanced prompt (with conversation history) back into the correct field
+
+## Changes Made
+1. **server.py**: 
+   - Added `prompt_field_mapping` to map tools to their input fields
+   - Modified to extract user input from the correct field
+   - Modified to store enhanced prompt in the correct field
+
+2. **tests/test_conversation_field_mapping.py**:
+   - Added comprehensive tests to verify the fix works for all tools
+   - Tests ensure conversation history is properly mapped to each tool's field
+
+## Verification
+All existing tests pass, including:
+- `test_conversation_memory.py` (18 tests)
+- `test_cross_tool_continuation.py` (4 tests)
+- New `test_conversation_field_mapping.py` (2 tests)
+
+The fix ensures that when continuing conversations, tools receive the full conversation history with embedded files, not just new content.
