Single tool with partial schema definition. Tool name follows verb_noun pattern (generate_llms_txt). Input schema present with proper type and description for the 'url' parameter. Output schema declared but lacks granularity on return structure. Description is adequate (106 chars) but generic, does not explain WHEN to use, what happens if generation fails, or prerequisites. Parameter description for 'url' is detailed (102 chars) and helpful, including format variants. However, output schema fields are minimally described (e.g., 'files_content' just says 'Content of generated files' without structure), and no error handling guidance provided in description. Risk category (WRITE) is correctly identified. Missing: per-parameter constraints, error recovery guidance, idempotency statement, and rate-limit warnings for the web-crawling operation.

• Expand tool description to 150-250 chars: explain WHAT (generates LLMs.txt per spec), WHEN (when you need AI-friendly site documentation), and WHAT HAPPENS (returns generated files and page count; fails gracefully on authentication walls).
• Document output schema in prose: 'Returns: success (bool), pages_processed (int), files_generated (array of filenames), output_directory (path), files_content (object mapping filename to content string).'
• Add error recovery guidance: 'If generation times out, the URL may be unreachable or very large. Try a smaller subdomain or specific documentation index.'
• State idempotency: 'This tool is idempotent if output_directory is unique per invocation. Rerunning with the same URL will regenerate files, existing files in the directory will be overwritten.'
• Add parameter constraint: document that 'url' must be publicly accessible and not behind auth. Mention common failures (JavaScript-rendered sites, paywalls, cloudflare blocks).
• Expand 'files_generated' field description: 'Array of relative filenames (e.g., ['llms.txt', 'llms-full.txt']) generated in output_directory.'
• Expand 'files_content' description: 'Object mapping filename (string) to file content (string). Omitted if files were written to disk; included only if inline response is requested (future feature).'
• Add timeout handling: document expected duration ('typically 10 - 300s depending on site size') and advise agent to set request timeout.

Inferred effective spec: 2025-06-18+.
