Critical gaps across all dimensions. Only 2 of 9 tools have visible input schemas (execute_code, run_workflow); 7 tools lack documented schemas entirely. Descriptions vary widely: execute_code and run_workflow are adequate (100+ chars), but echo, current_time, random, calculator, weather, wikipedia, and search have no descriptions visible in source. No parameter descriptions for most tools. No output schemas documented. No error handling guidance. Tool composition issues: execute_code and run_workflow are high-risk (IRREVERSIBLE, WRITE) with minimal safeguards. Most tools appear to be inferred from file paths rather than explicit registration with full definitions.

• Add explicit descriptions (50-200 chars) to all 7 undocumented tools. State WHAT each does, WHEN to use it, and what it returns. Example: 'echo: Returns the input string unchanged. Use to test connectivity or verify parameter passing.'
• Document output schemas for all tools. Specify field names, types, and whether results are paginated. Example for weather: {temperature: number, unit: string, location: string, timestamp: string}.
• Add parameter descriptions to execute_code and run_workflow. For execute_code.code, specify max length, timeout, and sandbox constraints. For run_workflow.input, document expected format per workflow (e.g. 'onboarding: user email or ID; status_check: service name').
• Implement confirmation/dry-run for high-risk tools. execute_code should support a 'dry_run' parameter that parses code without executing. run_workflow should require explicit confirmation before modifying state.
• Add error handling guidance. Document what errors each tool can return (e.g. 'execute_code: SyntaxError, TimeoutError, SandboxViolation') and recovery steps for each.
