Coding Agent engine implementation details (Cursor + Claude Code) — reference when modifying engine.ts or debugging Agent behavior.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cursor Engine Implementation Details
## Agent CLI Invocation
- Binary path: `~/.local/bin/agent` (not `cursor`, nor `cursor agent`)
- Uses standard `child_process.spawn` — no PTY (node-pty) needed since CLI version 2026.02+
- Key flags: `--output-format stream-json --stream-partial-output --force --trust --sandbox disabled --approve-mcps`
## stream-json Output Format
Output is clean NDJSON on stdout; `stripAnsi()` is retained as a safety net but is not expected to be needed.
One JSON object per line, main types:
```
{ "type": "system", "subtype": "init", "session_id": "xxx", ... } → Init; does not signal end of conversation
{ "type": "assistant", "message": { "content": [{ "type": "text", "text": "..." }] } } → Assistant text delta
{ "type": "tool_call", "subtype": "started", "tool_call": { "<XxxToolCall>": { "args": {...} } } } → Tool call started
{ "type": "tool_call", "subtype": "completed", "tool_call": { "<XxxToolCall>": { "args": {...}, "result": {...} } } } → Tool call completed
{ "type": "result", "subtype": "success", "is_error": false, "session_id": "xxx", "duration_ms": 1234 } → Normal end

How to install
mdr add 0xranx/golembot/.cursor/rules/engine-internals.mdc@sha256:f0c01b0f8c9a2bf8The line at the top of this page pins the label git:20260301.68eac18, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
