Server has 7 well-named tools with complete input schemas and descriptions. Naming follows verb_noun convention (create_sandbox, kill_sandbox, run_command, read_file, write_file, list_files, list_sandboxes). All tools have descriptions (10-100 chars). All parameters have type definitions and descriptions. However, output schemas are not documented, responses are JSON strings without declared structure. Error handling is minimal; no recovery guidance or actionable error messages. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite clear risk levels (WRITE, DESTRUCTIVE, READ_ONLY). Parameter descriptions lack format constraints and validation rules (e.g., 'timeout in seconds' but no mention of min/max bounds visible in descriptions, though schema shows them). Missing dependency hints and multi-step guidance.

• Document output schemas for all tools. E.g., create_sandbox returns {sandbox_id: string, template: string, timeout: number, security_preset: string}. Include this in tool descriptions or a separate schema field.
• Add tool annotations: mark read_file, list_files, list_sandboxes with readOnlyHint=true; mark kill_sandbox, write_file with destructiveHint=true; mark create_sandbox with idempotentHint=false (or true if retries are safe).
• Wrap SDK calls in try-catch blocks. Transform errors into actionable messages: 'Sandbox not found (ID: xyz). Call list_sandboxes() to see active sandboxes.' instead of raw SDK exceptions.
• Enhance parameter descriptions with explicit constraints. E.g., 'timeout in seconds (10 - 86400; default 300)' and 'security_preset: one of none, standard, strict (default: standard)'.
• Add dependency hints in create_sandbox description: 'Returns sandbox_id for use with run_command, read_file, write_file, list_files, and kill_sandbox.'
