flutter-performance SKILL.md skillA
flutter-performance from thiennc-tesoglobal/flutter-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Profile and improve Flutter runtime performance using profile-mode evidence, DevTools, frame analysis, rebuild inspection, memory, and app-size tools. Use for jank, slow startup, excessive work, leaks, or size regressions; route production logs, errors, and traces to flutter-observability.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Flutter Performance Measure a reproducible flow before changing code. Debug-mode timing is not release-performance evidence. A cause or fix named in the request is a hypothesis: confirm it with a measurement first. ## Establish evidence Record the target device, Flutter version, build mode, flow, dataset, and metric. Reproduce in profile mode on representative hardware when the issue is user-facing. ## Diagnose by symptom - Frame jank: inspect UI/raster timing, expensive build/layout/paint, shader or image work. - Excess rebuilds: inspect state subscription scope and widget identity before adding `const` mechanically. - Slow startup: trace initialization and defer work not required for first useful frame. - Memory growth: compare repeated-flow snapshots and find retained ownership, listeners, controllers, or caches. - Large binaries: use Flutter's app-size analysis and compare like-for-like release artifacts. - CPU-heavy Dart: use timeline/CPU profiling and consider isolates only after locating the work. Prefer removing or moving work over caching everything. Bound caches and preserve correctness. …

How to install
mdr add thiennc-tesoglobal/flutter-skills/flutter-performance@sha256:12b5a4750f1bc9acThe line at the top of this page pins the label git:20261103.d4e0895, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
