Cursor-agent CLI never invokes hooks.json on Linux (2026.08.11) — same version works on macOS

Cursor CLI

Describe the Bug

cursor-agent CLI on Linux never invokes any hook defined in hooks.json — zero hook events fire. The identical CLI version on macOS, with the same hook entries, fires them correctly.

This is not the previously-reported partial event coverage (Cursor CLI doesn’t send all events defined in hooks, Cursor CLI hooks) — in those threads at least the shell-execution events fired, including for a Linux user on a January build. On 2026.08.11 on Linux, no event fires at all: not stop, not beforeShellExecution, not beforeSubmitPrompt, none. I verified this by making the first line of every hook command append to a logfile — the logfile is never created, so the hooks are never spawned (this is non-invocation, not hooks failing silently). Since a January-build Linux user did get shell events, this looks like a regression rather than never-shipped platform support; possibly related, the 2026.08.11 release notes include hook-execution changes (“Hooks defined by installed plugins … now execute and refresh”).

Steps to Reproduce

  1. On a Linux machine (mine is a Docker devcontainer, details below), create ~/.cursor/hooks.json:
{
  "version": 1,
  "hooks": {
    "stop": [{ "command": "echo \"$(date) stop\" >> /tmp/hook-probe.log" }],
    "beforeShellExecution": [{ "command": "echo \"$(date) shell\" >> /tmp/hook-probe.log; echo '{}'" }]
  }
}
  1. Run cursor-agent "run ls and tell me how many files there are" and let it complete a shell command and finish the turn.
  2. Check /tmp/hook-probe.log.
  3. Result on Linux: the file does not exist — neither hook was ever invoked. Same result with project-level .cursor/hooks.json, in both default and --force (Run Everything) modes, interactive TTY and headless.
  4. Control: the identical hooks.json on macOS with the identical CLI version — hooks fire (verified both with a manual probe and with cmux’s hook integration, which produced its notifications normally).

Expected Behavior

Hooks defined in hooks.json should be invoked on Linux the same as on macOS — or, if Linux is unsupported, that should be documented (the hooks page and the cli/headless docs currently make no platform distinction).

Operating System

Linux

Version Information

Ubuntu 26.04 LTS arm64 (Docker devcontainer; host: Amazon Linux 2023, kernel 6.18.39, aarch64). Control test on macOS 26.4 (Apple Silicon).
cursor-agent 2026.08.11-e8db854 (same version on both platforms)

Does this stop you from using Cursor

No - Cursor works, but with this issue
