Single tool 'fwxray_scan' has a reasonable description (127 chars, within 10-1024 range) but critical gaps in schema completeness and parameter documentation. Input schema visible but lacks parameter descriptions, only 'target' with type string and basic description. No output schema documented. Tool name lacks action verb prefix (should be 'scan_firmware' or 'analyze_firmware'). No error handling guidance, no pagination support despite potentially large results, no idempotent/destructive hints. Naming does not follow verb_noun convention (pattern:tool). Parameter 'target' is ambiguous, unclear if it accepts file paths, URLs, or identifiers without resolution logic.

• Rename tool to 'scan_firmware' or 'diff_firmware' to start with action verb and match verb_noun convention (baseline: 90% of A+ tools start with action verb).
• Add second parameter 'baseline' or 'reference' with description: 'Path to baseline/reference firmware image for comparison. If omitted, scans target image in isolation.' This clarifies the diff functionality.
• Document output schema in tool description: 'Returns JSON object with fields: {new_binaries: [string], config_changes: [{key, old_value, new_value}], certificates: [string], entropy_regions: [{offset, size, entropy_value}]}'.
• Add error handling to return structured errors: '{"error": "file_not_found", "message": "Firmware image not found at /path/to/file. Verify path and retry.", "retryable": true}' instead of raw exceptions.
• Add parameter description for 'target': 'Absolute file path to firmware image (e.g., /firmware/router-v2.1.bin). Supports .bin, .img, .elf, .hex formats. Required.'
