Ingot provides 5 tools with clear action verbs and reasonable descriptions (avg 180 chars). All tools have documented input schemas with types. However, parameter descriptions are sparse or missing entirely (e.g., 'available_tools' and 'available_mcps' in route_and_load lack descriptions). Output schemas are not documented, callers must infer structure from code. Error handling is minimal; tools return plain strings or dicts without guidance on recovery. The 'route_and_load' tool combines routing + loading (violates single responsibility), and 'reload_skills' is a write operation without confirmation safeguards.

• Document output schemas for all tools. For list_skills, specify: [{name: string, description: string, uses: integer}]. For route_and_load, document the 'novel', 'match', 'related_match', 'skill_body' fields and their types.
• Add descriptions to route_and_load parameters: 'available_tools' (list of tool names the harness can invoke), 'available_mcps' (list of MCP server names available to the harness).
• Split route_and_load into two tools: route_skill (returns match metadata only) and load_skill_body (returns full instructions). This enables agents to preview matches before loading.
• Add error recovery guidance: 'No skill named X. Call list_skills() to see available skills, or suggest_skills() to find related ones.' This guides the agent's next step.
• Add a confirm_reload_skills tool or require a 'force' parameter with explicit confirmation. Prevent accidental reloads that could disrupt active agent sessions.
