Activation for Codex installs the supported Codex hook subset and writes an advisory sentinel. It does not touch Claude Code settings.
Codex does not expand ${PLUGIN_ROOT} inside a skill's own instructions — that
variable is only set for plugin-bundled hook commands (see
docs/KB-codex-platform-hooks-plugins.md). Codex does show you this skill's own
file path when it selects the skill ("Codex starts with each skill's name,
description, and file path" — official Codex Skills doc). Resolve the plugin
root from that path before running anything below:
# SKILL_FILE = the absolute path Codex showed you for this SKILL.md.
ANTI_HALL_ROOT="$(cd "$(dirname "$SKILL_FILE")/../../.." && pwd)"
test -f "$ANTI_HALL_ROOT/.codex-plugin/plugin.json" || { echo "anti-hall plugin root not found relative to $SKILL_FILE — aborting" >&2; exit 1; }
node "$ANTI_HALL_ROOT/codex/install-codex.js"
node "$ANTI_HALL_ROOT/codex/install-codex.js" --global

Codex limitations after activation:
api-guard and ship-it-guard are not hard hooks in Codex todayUse anti-hall-doctor to inspect the active state.
Explain anti-hall's optional DevSwarm integration from Codex — the hivecontrol reference KB, the (designed, unbuilt) workspace-tier orchestration, and the shipped layered recovery model (Claude-side companion: child self-report → supervisor poke → escalate-to-parent, automatic path NEVER kills, plus the on-demand devswarm-recover CLI — the only kill path). Use when the user asks about DevSwarm, hivecontrol, or the anti-hall liveness supervisor while working in Codex.
Explain and activate anti-hall's optional DevSwarm integration — the hivecontrol reference KB, the (designed, unbuilt) workspace-tier orchestration, and the shipped layered recovery model (child self-report → supervisor poke → escalate-to-parent, automatic path NEVER kills) plus the on-demand devswarm-recover CLI (the only path that ever kills). Use when the user asks "explain the anti-hall DevSwarm integration", "how do I activate the DevSwarm supervisor", "what DevSwarm addons does anti-hall have", "tune the liveness supervisor", "recover a stuck DevSwarm workspace", or anything about hivecontrol / DevSwarm workspaces from an anti-hall angle.
Check or update anti-hall from the local marketplace clone. Use when the user asks to update anti-hall, check whether anti-hall is current, or refresh the Codex port files.
Update anti-hall to the latest released version and show the changelog delta. Use when the user says "update anti-hall", "/anti-hall:update", "upgrade the plugin", "is anti-hall up to date", or "check for an anti-hall update". Fast-forward-pulls the marketplace clone, mirrors the new version into the plugin cache, prints what changed, then has the user reload in-session via /reload-plugins (rarely, a harness build may require a restart — the skill says so when relevant).
Brief the agent that installs or operates anti-hall (in Codex/OMX) on how the whole system works — a DERIVED, live enumeration of every installed hook, the shipped skills, the DevSwarm coordination substrate (mechanical triggers, store, CLI, auto-safe migration), and a docs/KB map. Generated from the real hooks.json and files on disk, never a hardcoded list, so it can't drift. Use when the user asks "brief me on anti-hall", "what's in this build", "how does the whole system work", or when onboarding an agent to install/run anti-hall. For "is it actually installed in Codex / do the guards fire", use anti-hall-doctor.
Brief the agent that installs or operates anti-hall on how the whole system works — a DERIVED, live enumeration of every installed hook (grouped by event, each with its own one-line purpose), the shipped skills, the DevSwarm coordination substrate (mechanical triggers, store, CLI, auto-safe migration), and a docs/KB map. Generated from the actual hooks.json and the files on disk, never a hardcoded list, so it can't drift. Use when the user asks "brief me on anti-hall", "what's in this build", "how does the whole system work", "give me the anti-hall system overview", "what hooks/skills/substrate ship here", or when onboarding an agent to install or run anti-hall. For "is it actually working / do the guards fire", use the `doctor` skill instead.
