Size Lens — paste the Flutter size report, get the shrink plan

Paste the *-code-size-analysis_*.json from flutter build --analyze-size (or an iOS App Thinning Size Report) and get a sequenced size-reduction plan: severity-ranked findings citing the measured evidence, real build commands (--split-debug-info, --tree-shake-icons, --split-per-abi, deferred components, WebP conversion), per-step impact estimates, and honest Google Play 200 MB store-cap math. A free client-side breakdown parses the report in your browser first — total, category bars, largest items and mechanical flags — and the raw file never uploads; the model receives only a compact facts summary that the browser then cross-checks: claimed savings must fit inside the measured bytes. Audit history follows your SkillSafe account with semantic search and a size delta against your previous run. A derived work of @flutter/flutter-reducing-app-size, the Flutter team's open-source app-size skill (BSD-3-Clause).

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
