Critical gaps across all dimensions. Tool descriptions are minimal (10-30 chars), far below the 194-char baseline for production tools. Input schemas present but lack parameter descriptions, the rubric requires descriptions for EVERY parameter. No output schemas documented. No error handling guidance. Tools like 'bash' and 'write' are high-risk (IRREVERSIBLE, WRITE) but lack safety patterns (confirmation, dry-run, permission gates). Naming is acceptable (verb-noun style) but descriptions do not explain WHEN to use each tool or what it returns. No evidence of idempotency, pagination, or composition patterns.

• Expand all tool descriptions to 50 - 200 characters. Example: 'read' → 'Read and return the full contents of a file. Use to inspect code, config, or text files. Returns file content as a string. Fails if file does not exist or is not readable.'
• Add descriptions to every input parameter. Example: 'file_path: Absolute or relative path to the file. Must be readable and within the project directory. Supports glob patterns (*.txt).'
• Document output schemas for each tool. Example: 'read returns {content: string, size_bytes: number, encoding: string}'. 'bash returns {stdout: string, stderr: string, exit_code: number}'.
• Add confirmation/dry-run pattern for bash, write, edit. Example: bash tool accepts optional 'dry_run: boolean' parameter; returns what would execute without running it. Requires explicit confirmation before actual execution.
• Add error classification and recovery hints. Example: 'File not found (ENOENT). Check the path and ensure the file exists. Use glob() to discover available files.' 'Invalid regex in grep: verify pattern syntax and escape special characters.'
