✅ Traced the source of working_dir: Discovered it comes from memory.runtime_info.working_dir which is set in memory.py line 202
✅ Identified the bug: Found that in agent_session.py line 162, the code was using config.workspace_mount_path_in_sandbox (which defaults to "/workspace") instead of str(runtime.workspace_root) (which reflects the actual SANDBOX_VOLUMES configuration)
✅ Found the correct pattern: Confirmed that main.py line 142 uses the correct approach with str(runtime.workspace_root)
✅ Created reproduction test: Built comprehensive tests that demonstrate both the bug and the fix
✅ Implemented the fix: Changed agent_session.py to use str(self.runtime.workspace_root) if self.runtime else config.workspace_mount_path_in_sandbox
✅ Added unit tests: Created comprehensive test suite in tests/unit/test_working_dir_fix.py with 4 test cases
✅ Verified fix works: All tests pass, including existing memory and session tests
✅ Code quality: Passed all pre-commit hooks and linting checks
Changes Summary:
The changes are concise and focused:
1. One-line fix in agent_session.py to use the correct working directory source
2. Comprehensive test suite to prevent regression and verify the fix works correctly
Now I'll ask the user about pushing the changes:
-------------------------
Summary
I successfully investigated and fixed the RecallObservation working_dir bug in local runtime. Here's what I found and accomplished:
Problem Identified
• Root Cause: In openhands/server/session/agent_session.py line 162, the code was using config.workspace_mount_path_in_sandbox (which defaults to "/workspace") instead of the runtime's actual workspace root
• Impact: When using local runtime with SANDBOX_VOLUMES={real_working_dir}:/workspace:rw, the RecallObservation.working_dir was always "/workspace" instead of reflecting the actual working directory
Solution Implemented
• Fixed the bug: Changed agent_session.py to use str(self.runtime.workspace_root) when runtime is available, falling back to the config value when runtime is not available
• Pattern consistency: This matches the correct pattern already used in main.py line 142
Testing & Verification
• Comprehensive test suite: Added 4 unit tests in tests/unit/test_working_dir_fix.py that:
◦ Verify the fix works correctly
◦ Demonstrate the original bug behavior
◦ Test RecallObservation working_dir propagation
◦ Prevent future regression
• All tests pass: Both new tests and existing memory/session tests pass
• Code quality: Passed all linting and pre-commit checks
Changes Made
3. openhands/server/session/agent_session.py: One-line fix to use correct working directory source
4. tests/unit/test_working_dir_fix.py: New comprehensive test suite (139 lines)
The fix is minimal, targeted, and ensures that SANDBOX_VOLUMES configuration is properly reflected in `RecallObservation`'s working_dir attribute for local runtime scenarios.
Would you like me to:
• Push the changes to a new branch and create a pull request?
• Keep the changes local for now?
• Any other specific Git workflow you prefer?

Testing: Created comprehensive unit tests that verify the fix and demonstrate the original bug.
Status: All changes are committed and ready. The fix is minimal, targeted, and includes proper safety checks. Headless mode was already working correctly and required no changes.
