Four tools with minimal descriptions (10-30 chars) and sparse parameter documentation. Tool schemas are present but lack parameter descriptions. 'run_cmd' is dangerous with no safety warnings. 'get_me' has empty inputSchema. No error handling guidance, no output schemas documented, no idempotency or permission gates. Naming is acceptable (verb_noun pattern) but descriptions fail to explain WHEN to use each tool or what they return. This server prioritizes authentication (JWT, tool-hash validation) over usability for LLMs.

• Expand all tool descriptions to 50-200 characters. Example: 'echo' → 'Echo back the input text exactly as received. Use to test connectivity or verify message transmission. Returns the same text in the response.'
• Add descriptions to all parameters. Example: 'message' → 'Text message to echo back (any string, max 10000 chars)'. 'path' → 'Absolute or relative file path to read (must exist, no symlink traversal)'. 'cmd' → 'Shell command to execute (bash syntax, runs as current user, 30-second timeout).'
• Document output schemas for each tool. Example: echo returns {"message": string}, read_file returns {"content": string, "size_bytes": integer}, get_me returns {"user_id": string, "login": string, "name": string}.
• Add confirmation step to run_cmd: require a 'confirm' boolean parameter or implement a two-step pattern (preview_cmd → execute_cmd). Include error recovery guidance: 'If command times out, try a simpler command or check system load.'
• Add parameter constraints: message max length, path validation (no /etc/shadow), cmd timeout (30s), and return clear errors: 'File not found at /path/to/file. Check path spelling.' instead of raw exceptions.

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