OneAPIChat exposes 31 tools with severe definition gaps. Most tools lack proper input schemas (many show only partial or inferred schemas). Descriptions are present but often generic or in Chinese, making LLM interpretation difficult. Critical issues: (1) browser_screenshot and browser_get_content have dummy/unused parameters instead of proper schemas; (2) chaoxing_* tools lack detailed parameter descriptions and return type documentation; (3) no error handling guidance or recovery patterns; (4) schemas are incomplete, many parameters lack type constraints, enums, or validation rules; (5) no tool annotations (readOnlyHint, destructiveHint) despite clear risk levels. The bash and server_exec tools accept destructive commands with minimal safeguards. Overall, this server reads as a rapid prototype rather than production-grade tooling.

• Remove dummy parameters from browser_screenshot, browser_get_content, and browser_get_snapshot. These tools take no input, declare empty required arrays and update descriptions to clarify.
• Expand chaoxing tool descriptions to 100-200 chars each. Document what each tool does, when to call it, and what it returns. Add parameter descriptions for 'ids', 'force', and 'timeout' fields.
• Add tool annotations: mark read/grep/glob/browser_navigate as readOnlyHint=true; mark bash/server_exec/write/edit/server_python as destructiveHint=true; mark idempotent tools accordingly.
• Implement confirmation pattern for destructive tools: add a 'dry_run' or 'confirm' parameter to bash, server_exec, and write. Return a preview and require explicit confirmation before executing.
• Move chaoxing_login credentials to server-side injection: accept a session_id or auth_token parameter instead of username/password. Store credentials in environment variables or a secure vault, never in tool parameters.
