FyAgent exposes 4 tools with critical definition gaps. Tool names lack clear action verbs (get_tool_versions is acceptable, but run_tool_lifecycle_action is vague). Descriptions are present but minimal (10-80 chars, below the 50-200 char LLM-optimized baseline). Input schemas are visible but lack parameter descriptions, the 'tools' array parameter has a description, but 'action' in run_tool_lifecycle_action lacks clarity on valid values. No output schemas documented. Error handling is absent. The tools appear to be Tauri command wrappers, not MCP-native definitions, tool registration is inferred from file paths, not explicit MCP schema declarations visible in source.
Get versions of specified tools or all valid tools
Open a terminal for a provider with optional working directory
Probe and report installation status of specified tools
Run lifecycle actions (install, update) for tools. Legacy command that now requires confirmed agent action.
No output schemas documented. LLMs cannot infer what fields to expect from tool responses, blocking downstream tool chaining and forcing unstructured parsing.
Parameter descriptions are incomplete. 'action' in run_tool_lifecycle_action lists valid values (install, install_official_npm, install_native, update) in the description text, not as an enum constraint. LLMs cannot reliably parse free-text enums.
Tool descriptions are too brief (10-80 chars, below 50-200 char baseline). 'Get versions of specified tools or all valid tools' lacks context on when to call this vs other discovery tools, and does not explain the return structure.

run_tool_lifecycle_action name is vague. 'run_tool_lifecycle_action' does not clearly signal what action is performed. Better: 'install_tool', 'update_tool', or split into separate tools (install_tool, update_tool).
No error handling guidance. Tools lack descriptions of failure modes, recovery steps, or actionable error messages. An LLM receiving a failure has no guidance on what to do next.
