-## Implicit Feedback (Beta)
-
-The Python SDK can emit implicit behavioral feedback to LangSmith so you can triage low-quality tool results without manually tagging runs.
-
-### Automatic configuration
-
-Set `LANGSMITH_API_KEY` in your environment and the SDK will initialize the implicit feedback manager on first tool execution. You can optionally fine-tune behavior with:
-
-- `STACKONE_IMPLICIT_FEEDBACK_ENABLED` (`true`/`false`, defaults to `true` when an API key is present)
-- `STACKONE_IMPLICIT_FEEDBACK_PROJECT` to pin a LangSmith project name
-- `STACKONE_IMPLICIT_FEEDBACK_TAGS` with a comma-separated list of tags applied to every run
-
-### Manual configuration
-
-If you want custom session or user resolvers, call `configure_implicit_feedback` during start-up:
-
-```python
-from stackone_ai import configure_implicit_feedback
-
-configure_implicit_feedback(
-    api_key="/path/to/langsmith.key",
-    project_name="stackone-agents",
-    default_tags=["python-sdk"],
-)
-```
-
-Providing your own `session_resolver`/`user_resolver` callbacks lets you derive identifiers from the request context before events are sent to LangSmith.
-
-### Attaching session context to tool calls
-
-Both `tool.execute` and `tool.call` accept an `options` keyword that is excluded from the API request but forwarded to the feedback manager:
-
-```python
-tool.execute(
-    {"id": "employee-id"},
-    options={
-        "feedback_session_id": "chat-42",
-        "feedback_user_id": "user-123",
-        "feedback_metadata": {"conversation_id": "abc"},
-    },
-)
-```
-
-When two calls for the same session happen within a few seconds, the SDK emits a `refinement_needed` event, and you can inspect suitability scores directly in LangSmith.

 ## Feedback Collection
 
-The SDK includes a feedback collection tool (`tool_feedback`) that allows users to submit feedback about their experience with StackOne tools. This tool is automatically included in the toolset and is designed to be invoked by AI agents after user permission.
+StackOne serves a feedback tool (`stackone_submit_feedback`) from the MCP endpoint, so it arrives in `fetch_tools()` alongside your action tools when it is enabled for your project. It is designed to be invoked by AI agents after user permission.
