Grom provides 7 tools with complete input schemas and descriptions. All tools have verb-noun naming (read_file, write_file, list_directory, delete_file, search_files, run_terminal, browse_web) and descriptions ranging 60 - 180 chars, meeting baseline minimums. However, descriptions lack LLM-optimized guidance on WHEN to use each tool vs alternatives, and parameter descriptions are minimal. No output schemas are documented. Error handling is absent, tools do not guide recovery or categorize failures. Security concerns: run_terminal accepts arbitrary shell commands with no validation, sanitization, or permission gating. write_file and delete_file lack confirmation patterns for destructive operations. Overall: functional definitions with room for LLM optimization and safety hardening.

• Add output schema documentation for each tool. E.g. search_files should document: {matches: [{file: string, line: number, text: string}], total: number}. This enables LLMs to chain tools and extract data correctly.
• Enhance run_terminal with input validation: reject commands containing dangerous patterns (rm -rf, dd, >, |, &&, ;). Implement a dry-run mode or require explicit confirmation for destructive commands. Add timeout and output size limits.
• Add confirmation pattern to write_file and delete_file. Return {action: 'confirm_required', summary: 'Delete file.txt (5KB)?'} and require a confirm_write or confirm_delete call before executing.
• Expand parameter descriptions with format constraints and examples. E.g. 'path: Workspace-relative path (e.g. src/index.ts, not /absolute/path). Supports glob patterns in search_files.'
• Add error recovery guidance. E.g. 'File not found. Try list_directory(path) to see available files.' Categorize errors: retryable (timeout, rate limit), user-fixable (invalid path), fatal (permission denied).
