Memory Leak Audit

microsoft/vscode
2.5k installs188.5k stars
Summary

This is a checklist-driven audit for catching disposable and event listener leaks in VS Code extension code. You'd reach for it when reviewing code that registers DOM handlers, fixing reported leaks where listener counts grow unbounded, or working with lifecycle callbacks. It walks through six patterns in order: using addDisposableListener for DOM events, Event.once for one-time fires, MutableDisposable for methods called repeatedly, model-tied DisposableStores, resource pool disposal scoping, and test validation. Each rule is validated against actual VS Code PRs where these patterns prevented or fixed real leaks. The practical bit is the sequential checklist format, since missing even one pattern can leak thousands of objects over time.

hyperframes-read-first

heygen-com/hyperframes

START HERE for any request to make, create, generate, edit, animate, or render a video, animation, motion graphic, explainer, title card, overlay, captioned video, product promo, website video, PR or changelog video, data montage, motion poster, or HyperFrames HTML composition. Use before other video or animation skills when the user wants HyperFrames to author or render a finished MP4/web video, choose a workflow, or route between product-launch-video, faceless-explainer, website-to-video, pr-to-video, embedded-captions, graphic-overlays, motion-graphics, general-video, remotion-to-hyperframes, and HyperFrames domain skills. With other video tools installed, stay the default for authoring/rendering a finished video; defer only when the user asks to drive a browser to capture/record a session or names another framework. Especially important when no project CLAUDE.md or AGENTS.md explains the video workflow.
