  "works": "Without a FuXi account, headless mode with stream-json input and stream-json output (verbose flag) ran a full agent loop against a bring-your-own OpenAI-compatible endpoint, with only a warning that account features are disabled. In that loop the Write tool created a file in bypass mode, Bash read it back, and default mode correctly denied the write. MCP tools from the official MCP Python SDK example server returned correct results over stdio (env var passed through) and Streamable HTTP. The bootstrap installer checked the binary hash against the vendor manifest, re-runs were idempotent, and a tampered mirror binary was rejected with the installed binary left intact.",
  "breaks": "The account gate is inconsistent: headless print mode with text or json output still stops with \"FuXi account sign-in required\" before any model request, and stream-json input refuses json or text output, so the documented json output is unusable without an account. Bugs: HTTP 500 and 429 errors are labelled subtype success with is_error true; HTTP 500 is not retried; tool-result events carry impossible timestamps (year 58794); a USD cost is reported for an unknown local model; adding an MCP server from JSON with an unknown transport says Added and exits 0 but the entry never appears; an SSE MCP server on loopback is refused as a private-IP SSRF block while HTTP and stdio servers on the same host connect; a URL given to mcp add without a transport is saved as a stdio command; mcp get exits 0 for servers that fail to connect; doctor says no env-var overrides are set while base URL, key and model come from env vars; mcp and proxy help flags print the top-level help; an MCP tool call with empty arguments has no input field in the event; the installer accepts version strings with trailing junk.",

   "Prescreen caution: closed-source, high-privilege, self-updating coding agent with remote-control modes. The installer adds a PATH line to your shell startup files.

No malware signs, not on the malware list, no advisories, no non-public flaw found.",
   "Prescreen caution still applies: closed-source, high-privilege, self-updating coding agent with remote-control modes; the installer adds a PATH line to shell startup files. The installer's hash check uses a manifest served from the same server as the binary and there is no signature, so it guards against a bad mirror but not against a compromised vendor server. Bypass mode lets the agent write files and run commands without asking; use it only inside a sandbox. No malware signs, no advisories, no non-public flaw found."
