Bug: read_module tool fails with "Missing required parameter: path"

[rabi]

Bug Description

When using the read_module tool to discover tool signatures, the tool fails with the error: Missing required parameter: path

This occurs even when the LLM correctly provides the parameter according to the tool's JSON schema.

Root Cause

There was a mismatch between the parameter name defined in the schema and the parameter name expected by the handler:

• Schema (ReadModuleParams struct): defines the parameter as module_path
• Handler (handle_read_module function): looks for a parameter named path

When the LLM reads the tool schema, it correctly uses module_path, but the handler rejects it because it's looking for path.

To Reproduce

• Start a Goose session with the code_execution extension enabled (this is typically enabled by default)
• Ask Goose to use an unfamiliar tool from another MCP extension
• Observe the error: Error: Missing required parameter: path

Expected behavior The read_module tool should return the tool signature and description for jira/search_issues, allowing Goose to understand the required parameters before calling the tool.

Actual Behavior The tool fails with "Missing required parameter: path" even though the module_path parameter was correctly provided according to the tool's JSON schema.
