Klee defines 7 tools with basic schemas and descriptions, but falls short of production quality. All tools have descriptions (10-100 chars, mostly adequate) and input schemas with type declarations. However, schemas are overly simplistic, all parameters are typed as 'string' with no enums, ranges, or format constraints. Descriptions lack actionable guidance on when to use each tool, error recovery, or prerequisites. Critical security issues: file_write, file_delete, and shell_exec are high-risk operations with no mention of permission gates, dry-run modes, or confirmation patterns. No output schemas documented. Error handling is absent, no guidance on retryability, user-fixable vs fatal errors, or recovery steps. Tool composition is reasonable (each does one thing), but parameter naming could be more explicit (e.g., 'path' should clarify 'absolute_file_path' or 'directory_path').

• Add enums to constrained parameters. E.g., shell_exec could restrict to safe commands or require explicit allowlist. file_list could accept 'recursive' as boolean enum.
• Document output schemas for all tools. E.g., file_list returns {files: [{name, type, size}], total_count}; web_search returns {results: [{title, url, snippet}], total}.
• Add confirmation/dry-run pattern to destructive tools. E.g., file_delete with optional 'confirm=true' parameter; shell_exec with 'dry_run=true' to preview command.
• Enhance descriptions with error recovery guidance. E.g., 'If file is too large (>10MB), returns truncated content. Call file_read with offset parameter to fetch chunks.'
• Add permission scope declarations. E.g., file_write requires 'write:filesystem'; shell_exec requires 'execute:shell'. Document in tool description.
