…ad the kwd error Adds a gotchas section so the brain fetches a tool's parameter schema before galaxy_run_tool and treats the masked 'Required parameter(s) kwd not provided' error as an input-shape mismatch to fix, not a sign the MCP/Galaxy version is incompatible. Pairs with the galaxy-mcp enrich-on-failure change.

Short addition to the agent gotchas. Before
galaxy_run_tool, fetch the tool's parameter schema (galaxy_get_tool_details(..., io_details=True), or the newgalaxy_get_tool_input_template) and build inputs to the real parameter names with the right flattened-key notation (section|param,conditional|selector,repeat_0|param). And if a call comes back with an opaque parameter error -- especiallyRequired parameter(s) kwd not provided in request-- treat it as your own input-shape mismatch to fix, not a sign the MCP or the Galaxy version is incompatible.Pairs with the galaxy-mcp change that enriches those errors at the source; this is the brain-side nudge so models do the schema lookup proactively and read the failure correctly.
