MUST USE after building/changing any UI or when asked whether a page, component, or TUI looks right. Rigorous visual QA across web/page and terminal UIs. Prefer browser:control-in-app-browser for unauthenticated browser/page QA in Codex, then Playwright/agent-browser/dev-browser. Captures screenshot/TUI evidence with bundled diff scripts, runs design-system/functional and visual-fidelity/CJK reviewer passes, then synthesizes a good/bad verdict. Triggers: visual QA, screenshot/pixel diff, UI look

One of 6 test cases the skill fixed. Same model, same prompt, with and without the skill.
We need to dispatch an independent oracle reviewer subagent to check visual layout and CJK wrapping in `src/components/Header.tsx`. Which specific agent_type role parameter should be supplied in the spawn call?

This skill may include examples copied from the OpenCode harness. In Codex, do not call OpenCode-only tools such as call_omo_agent(...), task(...), background_output(...), or team_*(...) literally. Translate those examples to Codex native tools:
| OpenCode example | Codex tool to use |
|---|---|
call_omo_agent(subagent_type="explore", ...) | multi_agent_v1.spawn_agent({"message":"TASK: act as an explorer. ...","agent_type":"explorer","fork_context":false}) |
call_omo_agent(subagent_type="librarian", ...) | multi_agent_v1.spawn_agent({"message":"TASK: act as a librarian. ...","agent_type":"librarian","fork_context":false}) |
task(subagent_type="plan", ...) | multi_agent_v1.spawn_agent({"message":"TASK: act as a planning agent. ...","agent_type":"plan","fork_context":false}) |
task(subagent_type="oracle", ...) for final verification | By default, record a self-review in the notepad: re-read the diff, run diagnostics, and capture evidence for every acceptance criterion. Only when the user demanded strict, rigorous, or high-accuracy review, use multi_agent_v1.spawn_agent({"message":"TASK: act as a rigorous reviewer. ...","agent_type":"lazycodex-gate-reviewer","fork_context":false}); include fork_context: false. |
task(category="...", ...) for implementation or QA | multi_agent_v1.spawn_agent({"message":"TASK: act as an implementation or QA worker. ...","agent_type":"lazycodex-worker-medium","fork_context":false}) |
background_output(task_id="...") | multi_agent_v1.wait_agent(...) for mailbox signals |
team_*(...) | Use Codex native subagents via multi_agent_v1.spawn_agent and multi_agent_v1.wait_agent; use multi_agent_v1.send_input and multi_agent_v1.close_agent only when exposed in the active tools list |
Role-specific behavior must be described in a self-contained message. Use fork_context: false to start the child with only the initial prompt (no parent history); use fork_context: true only when full parent history is truly required. Include any required conversation context, files, diffs, constraints, and requested skill names directly in the spawned agent's message. OMO installs these selectable agent roles into ~/.codex/agents/: explorer, librarian, plan, momus, metis, lazycodex-code-reviewer, lazycodex-qa-executor, and lazycodex-gate-reviewer - pass the matching name as agent_type so the child gets that role's model and instructions. Inspect the actual spawn schema: whenever agent_type is exposed, EVERY spawn MUST select an exact LazyCodex role, on V1 or V2. Implementation difficulty selects lazycodex-worker-low, lazycodex-worker-medium, or lazycodex-worker-high; clone QA can select lazycodex-clone-fidelity-reviewer. Never select generic worker or default. If a code block below conflicts with this section, this section wins.
Codex exposes ONE of two subagent tool surfaces per session; check your own tool list and route accordingly. If multi_agent_v1.* tools exist, use the table above as written. If instead a flat spawn_agent with a required task_name exists (multi_agent_v2), rewrite every multi_agent_v1.* example: multi_agent_v1.spawn_agent({...,"fork_context":false}) becomes spawn_agent({"task_name":"<lowercase_digits_underscores>","message":...,"agent_type":...,"fork_turns":"none"}) ("all" only when full parent history is truly required); send_input becomes send_message; do not call close_agent/resume_agent (finished agents end on their own; followup_task re-tasks one, interrupt_agent stops one); wait_agent takes only timeout_ms and returns on any child mailbox activity. Do not infer role support from V1/V2 or a model version. Legacy-schema exception: only if the actual schema lacks agent_type, omit that unsupported field and carry the complete role instructions in message, with history explicitly disabled. This cannot select a specialized TOML; an installed managed default supplies the medium worker for unnamed non-forks. The guard has no schema metadata and rejects unnamed calls, so report incompatible routing instead of retrying generically. Every deliberate full-history fork must still name its role: Codex skips role application on unnamed full-history forks, an upstream gap no LazyCodex default can repair. If a code block below conflicts with this section, this section wins. fork_context is rejected on multi_agent_v2 (fork_context is not supported in MultiAgentV2; use fork_turns instead).
When translating load_skills=[...], include the requested skill names in the spawned agent's message. If a code block below conflicts with this section, this section wins.
Omit optional keys you do not set. Never send items: [], message: "", model: "", reasoning_effort: "", or service_tier: "" — Codex rejects them (Items can't be empty, reasoning_effort must not be empty).
For work likely to exceed one wait cycle, require the child to send WORKING: <task> - <current phase> before long passes and BLOCKED: <reason> only when progress stops. A multi_agent_v1.wait_agent timeout only means no new mailbox update arrived; back off between waits (double the timeout up to ~5 minutes) instead of spinning short cycles. Treat a running child as alive. Fallback only when the child is completed without the deliverable, ack-only after followup, explicitly BLOCKED:, or no longer running.
Verify a rendered UI against intent using objective script evidence plus two parallel read-only oracle passes, then synthesize one good/bad verdict. The script numbers focus the reviewers. They are not the verdict.
In the commands below, $SKILL_DIR is this skill's own directory (the folder containing this SKILL.md). The bundled Node evidence CLI lives at scripts/visual-qa.mjs inside it; the TypeScript source in scripts/cli.ts is for development.
