27 tools with mixed quality. Most have basic descriptions (50-150 chars) and input schemas present, but lack depth. Parameter descriptions are minimal or missing context. No output schemas documented. Error handling is absent, tools return raw errors without recovery guidance. Security concerns: run_command and browser_evaluate expose code execution without sanitization hints. No tool annotations (readOnlyHint, destructiveHint, idempotentHint). Naming is generally verb-first (good), but some tools like 'delegate_task' and 'browser_evaluate' are vague about side effects. Composition is reasonable, tools are mostly single-purpose, but chaining is not documented (e.g., web_search returns results, but no indication if they include URLs for web_fetch).

• Add output schemas to all tools. Document field names, types, and meanings. E.g., web_search should return [{url: string, title: string, snippet: string}].
• Add tool annotations: mark read_file, list_directory, web_search, browser_extract as readOnlyHint=true; mark kill_process, write_file, move_file, browser_click as destructiveHint=true; mark browser_navigate, browser_wait as idempotentHint=true.
• Expand parameter descriptions to 50-100 chars with constraints. E.g., 'timeout in milliseconds (1-60000, default 5000)'; 'CSS selector (e.g., #id, .class, [attr=value])'; 'regex or glob pattern (e.g., *.txt, src/**/*.js)'.
• Add error recovery guidance. E.g., 'File not found. Verify path with list_directory(path) or list_allowed_directories().' for file tools; 'URL unreachable. Check network_enabled in update_agent_config().' for web_fetch.
• Document tool chaining. E.g., 'web_search returns URLs suitable for web_fetch'; 'browser_extract returns selectors for browser_click'; 'search_files returns paths for read_file'.
