Agent Skills: Codex QA

Codex QA

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.

Golden rules (read before running anything)

• QA ONLY our plugin. Everything that spawns codex uses an isolated 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).
• Prove the real home stayed clean. Every script shasums ~/.codex/config.toml before and after and asserts it is unchanged. If you script by hand, do the same.
• The interactive codex is a shell function that injects --profile quotio. Bash scripts bypass it and get the real binary; never rely on the interactive alias. See references/isolation.md.
• The first-party way to prove a hook fired is the app-server notification stream (hook/started / hook/completed), not log scraping. See references/app-server.md.
• The captured JSON / pane IS the evidence — write it under .omo/evidence/<YYYYMMDD>-<slug>/ (no evidence file == the QA did not happen).

Setup

cd <this-skill-dir>                        # .agents/skills/codex-qa
bash scripts/lib/common.sh --self-check    # confirm deps + isolation harness

Docker 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.

Router: pick your case

| 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 |

Scripts index (each is its own regression test)

| 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-terminal

The 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.

Match QA to your change scope

• Component / hook logic (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.
• Installer / config.toml (packages/omo-codex/src/install/*): install-verify.sh.
• Anything that affects a live session (hooks, agents, MCP wiring): app-server-drive.sh --plugin, and tui-smoke.sh --plugin if the TUI path matters.

Capturing evidence

ev=".omo/evidence/$(date +%Y%m%d)-codex-qa-<slug>"; mkdir -p "$ev"
bash scripts/app-server-drive.sh --plugin > "$ev/app-server-drive.json" 2>&1
bash scripts/install-verify.sh --self-test > "$ev/install-verify.txt" 2>&1

On /debugging

There is no /debugging command in Codex. To observe a run: the app-server notification stream (above), RUST_LOG=debug on the app-server's stderr, the logs SQLite under $CODEX_HOME, the TUI's /debug-config, and the codex debug … subcommands. See logging-debug.md.
