What problem does it solve?

Migrating a WeChat Mini Program from the Skyline renderer to WebView traditionally requires manual code review, risky rewrites of existing compatibility workarounds, and extensive regression testing to ensure page consistency. This skill automates the entire migration workflow, eliminates guesswork about which Skyline-specific features need manual replacement, and produces a debug document for downstream agents to maintain the migrated program.

Core Features & Use Cases

• Deterministic Migration Scanner: Automatically inventories all Skyline-specific code, workarounds, and configuration, categorizing each item as mechanical (auto-applied), keep (preserved for consistency), verify (needs runtime check), or rewrite (requires manual replacement).
• Pre-Edit Migration Map Generation: Produces a detailed MIGRATION-MAP.md document before any code changes, listing all findings, config diffs, and manual-review gates for rewrite items, so the migration plan is fully reviewable.
• Minimal-Diff, Consistency-First Migration: Flips the renderer setting automatically, preserves all existing Skyline-era workarounds that still work under WebView, and only fixes real visual/behavioral deltas verified via the vince-mp CLI, avoiding unnecessary rewrites.
• Use Case: Ideal for teams migrating production WeChat mini programs off Skyline, ensuring zero unexpected visual or behavioral changes while minimizing code changes and providing full auditability for the migration process.

Quick Start

Use the mp-groundline skill to migrate your WeChat mini program from the Skyline renderer to WebView with full page consistency, and generate a MIGRATION-MAP debug document for downstream agents to use for future maintenance.
