Crit + Codex.
Codex is the only agent besides Claude Code with a plan hook: proposed plans in Plan mode go through Crit for inline review before the turn completes. Install the plugin for the hook; skills-only install works for on-demand $crit on files already on disk.
Install the plugin (recommended):
$ cd ~ && crit install codex-plugin
Installs the Crit Codex plugin globally: $crit and crit-cli skills, a local marketplace entry, and the proposed-plan Stop hook. Enables the plugin in ~/.codex/config.toml automatically.
Per-project alternative:
$ crit install codex
Run from the project root for skills only — $crit and crit-cli land in .agents/skills/. No plan hook. For the hook too, run crit install codex-plugin instead and commit plugins/crit/.
$crit skill
Starts the review loop when you type $crit in Codex chat. The agent launches Crit, waits for your inline comments, then revises until you approve.
In your agent's chat:
$crit
crit-cli skill
Auto-activates when the agent works with review files, shares a review, or syncs to a PR. No manual invocation. Talk to the agent normally and it picks the right crit subcommand.
Spawn a team of agents to review the work
Your main agent runs /crit and dispatches reviewer subagents. Each one leaves inline comments via crit. You scan the comments and decide which ones to act on.
In your agent's chat:
Run /crit and spawn a team of agents to use crit to review the work. I'll decide which comments to proceed with.
Review from your phone
The share URL renders on mobile, so you can leave inline comments from the couch while the agent keeps grinding.
In your agent's chat:
Share the current review with crit and send me the link.
Proposed-plan review hook
Intercepts Codex's Stop hook when the agent proposes a plan in Plan mode. Reads the in-chat <proposed_plan>, writes it to disk, and runs crit plan-hook --mode codex so you can comment inline before the turn ends. Ships only with crit install codex-plugin — bare $crit needs a file path and cannot review in-chat plans on its own.
Disable per-shell or globally:
export CRIT_PLAN_REVIEW=off
