This server defines 7 tools via fastmcp with basic parameter schemas present. However, multiple critical gaps significantly undermine quality: (1) Tool names lack clarity, 'file_system_create_directory_tool' is verbose and doesn't follow verb_noun pattern; names should be 'create_directory', not 'file_system_create_directory_tool'. (2) Descriptions exist but are extremely terse (10-30 chars), well below the 50-200 char production baseline and insufficient for LLM decision-making. Examples: 'Create a directory within the sandbox' (38 chars) and 'Write content to a file within the sandbox' (42 chars) lack context on when/why to use vs. alternatives, or what the tool returns. (3) Parameters lack descriptions in the visible source, 'path' and 'content' are named but have no type specs or constraints visible in the tool definitions shown. (4) No output schema documented for any tool, LLMs cannot plan downstream calls or extract results. (5) No error handling strategy visible, what happens on permission denied, disk full, or invalid paths? (6) Shell execution tool is high-risk but lacks granular permission checks, dry-run support, or command validation guidance. (7) LLM tools (OpenAI/Gemini) lack API key management documentation and rate-limit guidance. The server demonstrates competent infrastructure (Docker, type checking, tests) but tool definitions themselves are below production standards.

• Rename tools using verb_noun pattern: 'create_directory', 'write_file', 'read_file', 'list_directory', 'execute_command', 'generate_code_openai', 'generate_code_gemini'. Target ~18 char average.
• Expand all descriptions to 100-200 chars. Include: WHAT (action), WHEN (use case), and RETURN (what the LLM gets back). Example: 'Create a new directory at the specified path within the sandbox. Use this to organize files before writing. Returns {path, created_at, permissions}.'
• Add parameter descriptions for all fields. For 'path': 'Relative filesystem path (max 255 chars, no '..' or symlinks). Relative to sandbox root.' For 'content': 'UTF-8 text to write. If file exists, overwrite completely. Max 10MB.'
• Document output schemas for every tool. Example for write_file: {success: bool, path: string, size_bytes: int, created: bool, error?: string}. Example for list_directory: {entries: [{name: string, type: 'file'|'dir', size: int}], total: int}.
• Add error handling and recovery guidance. For filesystem tools: 'If path not found, call list_directory first to confirm. If permission denied, check sandbox access rules.' For shell tool: 'Commands like rm are irreversible, require explicit confirmation first (pattern: confirmation-request).'
• Implement dry-run support for execute_shell_command_tool. Add an optional 'dry_run: bool' parameter. When true, return what would execute without running it. This enables agent validation before irreversible operations.
• Document API key injection for LLM tools. Add: 'API keys (OPENAI_API_KEY, GOOGLE_API_KEY) must be set as server environment variables. Never pass as parameters.' Document rate limits and cost implications.

Inferred effective spec: <=2025-11-25.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
