About this skill
The problem it addresses
Many WeChat Mini Program incidents are not feature bugs, but boundary failures in audit compliance, ad placement, local storage, and cross-project collaboration:
- A WeChat ID, email address, or official account appears in the UI and is rejected as channel diversion;
- wx:if, hidden, or bottom-ad positioning is changed incorrectly, causing occupied screen space or blank areas;
- “Data lost after restart” is usually caused by broken _contentDirty / _layoutDirty protection;
- AI assistants add unrequested features in user projects or misread “enforce subscription” as “make it free.”
How the skill works
wechat-miniprogram-guardian turns maintenance lessons from live projects into actionable references:
- Greenfield builds: follow greenfield-build.md for app.json, local-first storage, separated ad systems, and compliant entry points;
- Live project fixes: use audit-compliance.md, ad-systems.md, and local-first-storage.md to diagnose ads, storage, and audit issues;
- Collaboration guardrails: use collaboration-rules.md and agent-collaboration-guardrails.md to read code first, lock file paths, and verify completion with grep;
- Self-upgrade: append sanitized “problem + approach” entries to learnings.md, without storing code, file paths, secrets, or personal data.
The execution flow is explicit: locate the current implementation with keyword search, separate safe-to-change modules from frozen ones, run syntax and keyword checks after edits, and state whether frontend upload or cloud-function deployment is required for the change to take effect.
Use Cases
- When a Mini Program submission is rejected for diverting users to other channels, replace WeChat IDs or emails with a compliant contact button.
- When the bottom ad occupies space or leaves blank gaps after hiding, locate the ad container and adjust its bottom offset without touching incentive videos.
- When saved data disappears after restart, inspect local-first storage and verify _contentDirty or _layoutDirty protection logic.
- Before enabling subscription, credits, or access gates in a live project, read existing code, lock file paths, and avoid unrequested feature changes.
Best For
- Frontend engineers maintaining a live Mini Program who want to reduce audit rejections, ad layout failures, and storage rollback incidents.
- Independent developers taking over an existing Mini Program who need to fix production issues without breaking established rules or ad systems.
- Engineers using AI assistants to edit Mini Program code who need guardrails against unrequested changes, false completion, and ad deletion.
- Mini Program product managers owning word-library import, credits, and subscription rollout who need data import, cloud deployment, and access-control rules.
