Refactor a growing WeChat Mini Program whose top-level navigation has become scattered across tabs such as home, profile, inbox, integrations, or settings into a clearer hub or center structure. Use when Codex needs to regroup top-level tabs, separate high-frequency action flows from low-frequency settings, define internal hub sections, or migrate detailed pages without collapsing everything into one long page.
Diagnose WeChat DevTools failures through the official CLI instead of relying only on GUI screenshots. Use when Codex needs to run `open`, `preview`, or related commands, discover the live service port, classify whether a failure is CLI-visible, host-side, or outside preview scope, and apply or suggest only safe repo-level fixes.
Use host-side WeChat DevTools automation to inspect GUI-only runtime and interaction failures that do not show up in CLI `preview`. Trigger when page entry, taps, websocket-based DevTools automation, or run-directory evidence such as `report.json` and `trace.log` are needed to separate repo bugs from IDE session problems, local service blockers, or remaining visual-only issues.
Recover a WeChat Mini Program repository after wrong-root import, DevTools template residue, stale compile conditions, or TypeScript-recognition drift. Use when Codex needs to restore the intended repo shape, remove generated clutter, or tell the user exactly what to fix inside DevTools.
Validate or design a WeChat Mini Program scaffold, repository layout, or TypeScript setup against official platform rules. Use when Codex needs to review `project.config.json`, `app.json`, `miniprogramRoot`, page or component file sets, or the initial repo skeleton before feature work begins.
Simplify on-page WeChat Mini Program copy so main surfaces become shorter, more action-first, and more user-facing. Use when Codex needs to trim verbose labels, mixed implementation detail, over-explained settings, or long empty-state and status text without changing the underlying business flow.
