Module cursor 

Cursor AI installer adapter.

What we touch

• ~/.cursor/mcp.json — mcpServers.spool entry
• ~/.cursor/settings.json — hook entries under cursor.hooks
• ~/.cursor/hooks/spool-*.sh — two hook scripts

Cursor hook format

Cursor uses a settings.json with the shape:

{
  "cursor.hooks": {
    "onSessionStart": [{"command": "...", "timeout": 5000}],
    "onSessionEnd":   [{"command": "...", "timeout": 10000}]
  }
}

Unlike Claude Code (which wraps each entry in a {matcher, hooks: [...]} envelope) and Codex (flat hooks.json), Cursor puts hooks inside its main settings.json under the cursor.hooks namespace.

Binary resolution

Same strategy as Claude/Codex: default to ~/.cargo/bin/spool-mcp, with --binary-path as an escape hatch.
