codex-qa — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited codex-qa (Agent Skill) and scored it 65/100 (yellow). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 4 high-severity and 2 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

QA the omo Codex Light edition (packages/omo-codex/, shipped as lazycodex). We exercise OUR plugin in a REAL Codex while touching nothing of the user's setup: an isolated CODEX_HOME + a local mock model means no real API call and the real ~/.codex is never read or written. Each helper script ships a --self-test that asserts its scenario against the live machine, so the scripts are both the QA tools and their own regression checks.
Verified against codex-cli 0.140.0 (node, jq, tmux, bun on macOS). Confirm with codex --version; check a flag with codex <cmd> --help.
CODEX_HOME (created by cqa_mk_isolated_home) and a LOCAL mock model provider (cqa_start_mock). Never QA against the real ~/.codex, never hit a real model API. The bundled scripts enforce this; if you run codex by hand, export CODEX_HOME="$(mktemp -d)/codex"; mkdir -p "$CODEX_HOME" FIRST (a set CODEX_HOME must already exist or codex hard-errors).
~/.codex/config.toml before and after and asserts it is unchanged. If you script by hand, do the same.
--profile quotio.Bash scripts bypass it and get the real binary; never rely on the interactive alias. See references/isolation.md.
stream (hook/started / hook/completed), not log scraping. See references/app-server.md.
.omo/evidence/<YYYYMMDD>-<slug>/ (no evidence file == the QA did not happen). That directory is gitignored: the files stay local, the PR body carries the summary and decisive excerpts, and nothing under it is ever committed.

bash scripts/lib/common.sh --self-check # confirm deps + isolation harnessDocker is the default QA surface. Run this QA inside a disposable container that has the latest codex and a copy of your config, with the host ~/.codex untouched: script/agent/qa-docker.sh (see references/docker-qa.md). The local scripts below are the fallback for when Docker is unavailable or on Windows.
| You need to… | Run | Deep dive |
|---|---|---|
| Prove a plugin hook fires in a LIVE Codex turn (first-party) | scripts/app-server-drive.sh --plugin | app-server.md |
| Prove the app-server driver itself works (no plugin, fast) | scripts/app-server-drive.sh --self-test | app-server.md |
| Install the LOCAL build into an isolated home + assert it landed | scripts/install-verify.sh --self-test | install-verify.md |
| Pin ONE component's hook logic deterministically (no codex) | scripts/hook-unit-probe.sh --self-test | components-hooks.md |
| Smoke the real TUI under tmux (boots, renders, survives) | scripts/tui-smoke.sh --self-test | logging-debug.md |
| Watch runtime logs while QAing | (see reference; RUST_LOG / logs DB / /debug-config) | logging-debug.md |
| Script | --self-test asserts |
|---|---|
scripts/lib/common.sh --self-check | deps present; isolated CODEX_HOME is created inside a sandbox and auto-removed on exit; mock model serves the Responses SSE; real ~/.codex unchanged |
scripts/app-server-drive.sh | --self-test: a bare turn completes and the mock assistant text comes back. --plugin: installs local omo, drives a turn, and asserts hook/completed for sessionStart,userPromptSubmit |
scripts/install-verify.sh | local omo installs into the isolated home; config.toml enables omo@sisyphuslabs; component bins + agent TOMLs linked in the sandbox; real ~/.codex unchanged |
scripts/hook-unit-probe.sh | the ultrawork component injects <ultrawork-mode> on an ulw UserPromptSubmit (also a manual --component/--event mode) |
scripts/tui-smoke.sh | the real codex TUI boots in the isolated home, renders, and survives (no early exit); captures the pane |
To tell a dev dogfood build apart from a published one on a REAL ~/.codex (NOT the isolated QA home), the repo ships bun run install:codex-dev, which stamps the plugin version as dev — visible as the (OmO dev) hook-status prefix every turn and as a [DEV] badge in omo get-local-version. Use it to confirm which build is loaded during manual dogfooding; it writes to the real home, so it is NEVER part of the isolated QA flow above.
When TUI visual QA evidence is needed, follow docs/reference/web-terminal-visual-qa.md: render the TUI through the real xterm.js web terminal - NEVER the tmux capture-pane frame, which degrades color and CJK width:
node script/qa/web-terminal-visual-qa.mjs --title "Codex TUI QA" \
--command "codex" --input "{Enter}" \
--evidence-dir .omo/evidence/<slug>/codex-web-terminalThe helper runs a real pty, renders it in xterm.js under Chrome, and writes terminal.txt, terminal-ansi.txt, terminal.png (true color), and metadata.json (--from-file <capture.ansi> replays a saved raw stream). Use that artifact set for TUI visual QA; use app-server-drive.sh --plugin for assertion-grade hook behavior.
packages/omo-codex/plugin/components/*):hook-unit-probe.sh for the exact stdout, THEN app-server-drive.sh --plugin to prove the live wiring. See components-hooks.md.
packages/omo-codex/src/install/*):install-verify.sh.
app-server-drive.sh --plugin, and tui-smoke.sh --plugin if the TUI path matters.
