/**

 * level), and `--enable <FEATURE>` now means `-c features.<name>=true`
 * (verified on 0.147.0), so the legacy spelling is headed for hard
 * rejection. This is the ONE source
 * of truth: resolvers interpolate it directly and templates reference it via
 * the {{CODEX_WEB_SEARCH_FLAG}} token — never write the flag inline.
 *
 * Semantics note: unlike the legacy flag (which yielded to an existing
 * top-level `web_search` in config.toml), the -c form explicitly overrides
 * it. Deliberate: gstack wants deterministic cached search for review
 * invocations. Native `codex review` disables web search regardless of
 * configuration, so on that path the flag is a harmless no-op.

 *
 * Emits ONE self-contained bash block (the caller must place it in a single
 * fenced block — CLAUDE.md: each block is a fresh shell, so functions sourced
 * here do NOT persist to later blocks). It:
 *   1. reads the `codex_reviews` master switch,
 *   2. sources `gstack-codex-probe`,
 *   3. runs `command -v codex` (literal — keeps the e2e substring assertion),
 *      then `_gstack_codex_auth_probe`, then `_gstack_codex_version_check`,
 *   4. logs the relevant `_gstack_codex_log_event` for each non-ready outcome,
 *   5. sets ONE canonical mode var and echoes `CODEX_MODE: <mode>` so the agent
 *      gates later blocks on the echoed value.
 *
 * Mode values: `disabled` (config off) | `not_installed` | `not_authed` |
 * `broken_install` | `sandbox_unavailable` | `model_unusable` | `unverified` | `ready`.
 * The path is host-rewritten at gen-skill-docs time (pathRewrites), so the
 * literal `~/.claude/skills/gstack` is correct here and becomes `$GSTACK_ROOT`
 * etc. for non-Claude hosts.
 *
 * `disabledBehavior` controls the `disabled`-mode interpretation, which is the
 * one branch that legitimately differs per caller (D1):
 *   - `skip-all` (plan / doc reviews): disabled means no extra review step at
 *     all — skip the section, no Claude fallback.
 *   - `codex-only` (diff adversarial): disabled gates only the Codex passes; the
 *     free Claude adversarial subagent still runs.

Skip the outside invocation and follow the workflow's native-review instructions below. Conflicting inherited harness markers are not grounds to guess another provider.

- **\`broken_install\`** — the CLI is on PATH but cannot execute (spawn ENOENT, non-executable binary, missing vendor payload). Print: "Codex is installed but its binary cannot run — Codex passes skipped. Reinstall: \`npm install -g @openai/codex\`." Relay the probe's HINT lines. ${nativeRoute}
- **\`model_unusable\`** — the selected model (see \`CODEX_MODEL:\`) is invalid or unavailable to the account (#2477: HTTP 400 on every call). Relay the probe's HINT lines and the fix (\`GSTACK_CODEX_MODEL=<supported-model>\` or config.toml \`model\`); never substitute a model. ${nativeRoute} The ~10s round trip is cached for 1h.
- **\`sandbox_unavailable\`** — Codex's sandbox cannot start here (containers without user namespaces); the probe printed the reason and fix. No paid call ran; outside coverage is unavailable. ${nativeRoute}
- **\`ready\`** or **\`unverified\`** — run the Codex pass below. \`unverified\` means the model check timed out; say so, and let the pass's own verdict decide.`;

Dispatch through the Agent tool only: invoking the target as a Skill, or executing its workflow inline in your own context, forfeits the fresh-context isolation this dispatch exists for, even though the skill may appear in your available-skills list; the explicit flag already makes the Agent call block. (Where a step defines an inline fallback, it applies only after a dispatched subagent has failed.)`;
