How to add a guard layer to Codex through its plugin browser with Jev Guard

Install the Jev Guard plugin in Codex and trust its hooks so tool calls are checked.

Who it is forA Codex user who wants the same deny and warning checks as other agents, installed from inside Codex.

The problemCodex runs tool calls without a second review, and the user needs a guard that installs through the plugin system rather than manual config editing.

The outcomeCodex tool calls are checked before they run, with deny decisions and warnings for ask-level risks, and results are flagged when they contain injected text.

What you need first

  • Node.js and npm, to install the jev-guard package or run the install commands
  • One provider key: a TypeSafe key from console.typesafe.ai, a vck_ Vercel AI Gateway key, or an sk-or- OpenRouter key
  • The coding agent you want to guard, installed on the same machine

Steps

  1. Run codex plugin marketplace add leepokai/jev-guard
  2. Open the plugin browser in Codex and install Jev Guard
  3. Run /hooks in Codex and trust the Jev Guard hooks
  4. Trigger a harmless tool call and confirm the guard runs

Prompt for your agent

Install the jev-guard plugin in Codex from the leepokai/jev-guard marketplace, trust its hooks with /hooks, and report whether the hooks list shows jev-guard as trusted. Do not run any destructive command to test it.

Caveat. The README says Codex has no ask decision yet, so ask-level risks appear as a warning rather than a prompt.
