Critical gaps across all dimensions. 18 tools with minimal or no visible schema definitions in source code. Descriptions are present but extremely brief (10-80 chars), well below the 50-200 char LLM-optimized baseline. No input parameter descriptions visible for most tools. Tools like Bash and PowerShell expose dangerous operations with only command/run_in_background params documented, no validation guidance. File tools (Read, Write, Edit, Grep, Glob) lack path validation, encoding, or size constraints. Task/Todo tools are bookkeeping-only with no clear user-facing semantics. No output schemas documented. Error handling is absent, no recovery guidance, no categorization of retryable vs fatal errors. STDIO transport caps protocol readiness at 50, but definition quality itself is severely deficient.

• Add JSON Schema input definitions for all 18 tools. Include type, description, enum constraints, and min/max bounds for each parameter. E.g., Bash should declare command as string with max length, run_in_background as boolean with default false.
• Expand tool descriptions to 80-150 characters. Include WHAT the tool does, WHEN to use it, and what it returns. E.g., 'Read a file from disk and return its contents as a string. Use this to inspect configuration, source code, or logs. Returns file_content and file_size.'
• Add output schema documentation for all tools. Define the structure of success responses (e.g., TaskCreate returns {task_id: string, created_at: ISO8601, status: 'pending'}). Document error responses with actionable recovery hints.
• Implement confirmation/dry-run for destructive tools (Bash, PowerShell, Write, Edit, TaskStop). Add a 'dry_run' boolean parameter or require explicit confirmation before executing. Return a preview of what will happen before committing.
• Add path validation and security constraints to file tools. Document that paths must be relative to a safe root, reject absolute paths and '..' sequences, and specify max file size limits. Include encoding hints (UTF-8 assumed, binary files rejected).
