-# FastMCP Development Guidelines
-
-## Git
-
-This project uses `pre-commit` to run checks on all commits. If your commit doesn't pass the checks, it will not be created. Do not attempt to amend commits to pass checks.
-
-## Documentation
-
-- Documentation uses the Mintlify framework
-- Files must be present in docs.json to be included in the documentation
-
-## Testing and Investigation
-
-### In-Memory Transport - Always Preferred
-
-When testing or investigating FastMCP servers, **always prefer the in-memory transport** unless you specifically need HTTP transport features. Pass a FastMCP server directly to a Client to eliminate separate processes and network complexity.
-
-```python
-# Create your FastMCP server
-mcp = FastMCP("TestServer")
-
-@mcp.tool
-def greet(name: str) -> str:
-    return f"Hello, {name}!"
-
-# Pass server directly to client - uses in-memory transport
-async with Client(mcp) as client:
-    result = await client.call_tool("greet", {"name": "World"})
-```
-
-### When to Use HTTP Transport
-
-Only use HTTP transport when testing network-specific features. Prefer StreamableHttp over SSE as it's the modern approach.
-
-```python
-# Only when network testing is required
-async with Client(transport=StreamableHttpTransport(server_url)) as client:
-    result = await client.ping()
-```
-
-## Development Workflow
-
-- You must always run pre-commit if you open a PR, because it is run as part of a required check.
-- When opening PRs, apply labels appropriately for bugs/breaking changes/enhancements/features. Generally, improvements are enhancements (not features) unless told otherwise.
-- NEVER modify files in docs/python-sdk/**, as they are auto-generated.
-- Use # type: ignore[attr-defined] in unit tests when accessing an MCP result of indeterminate type instead of asserting its type
