## Summary - Return an explicit `[DEBUG] stacktrace: unavailable ...` note when the stacktrace debug flag is enabled but the tool error payload has no stacktrace. - Preserve existing behavior for real stacktraces and for developer messages, including not leaking developer details unless the developer-message flag is enabled. - Clarify the toolkit-author docs around when stacktraces exist, such as unhandled exceptions or chained `raise ... from exc` errors. ## Test plan - `pre-commit run --files CLAUDE.md libs/arcade-mcp-server/arcade_mcp_server/_debug_exposure.py libs/tests/arcade_mcp_server/test_debug_exposure.py libs/tests/arcade_mcp_server/test_debug_exposure_integration.py` - `uv run --with pytest --with pytest-asyncio --with pytest-cov pytest libs/tests/arcade_mcp_server/test_debug_exposure.py libs/tests/arcade_mcp_server/test_debug_exposure_integration.py -v` - `ruff format --check libs/arcade-mcp-server/arcade_mcp_server/_debug_exposure.py libs/tests/arcade_mcp_server/test_debug_exposure.py libs/tests/arcade_mcp_server/test_debug_exposure_integration.py` - `ruff check libs/arcade-mcp-server/arcade_mcp_server/_debug_exposure.py libs/tests/arcade_mcp_server/test_debug_exposure.py libs/tests/arcade_mcp_server/test_debug_exposure_integration.py` <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **Low Risk** > Low risk: changes are limited to debug-only error-message augmentation when an explicit env flag is enabled; default runtime behavior is unchanged. Main risk is only in local debugging scenarios where the new note could affect log parsing or expected error text. > > **Overview** > When `ARCADE_DEBUG_EXPOSE_STACKTRACE_IN_TOOL_ERROR_RESPONSES` is enabled, tool error messages now **always include a stacktrace debug section**: either the actual stacktrace (when present) or an explicit `[DEBUG] stacktrace: unavailable ...` note when the tool error payload had no stacktrace. > > Adds/updates unit + integration coverage for the missing-stacktrace case and adjusts expectations around “flag enabled but no content.” Updates toolkit-author docs to clarify when stacktraces exist, and bumps `arcade-mcp-server` patch version to `1.21.2`. > > <sup>Reviewed by [Cursor Bugbot](https://cursor.com/bugbot) for commit 7d85196a30d8d29be98ffb252a13ef2a78057742.
