Start a local JS/TS dev server and expose it through an ngrok tunnel so the user can test it from a phone, another machine, or while away from their laptop. Trigger when the user says things like "expose my dev server", "ngrok this", "tunnel localhost", "share my local app", "test on my phone", "make my app reachable from outside", "I want to test this remotely", "give me a public URL for my dev server", or any variant where they want a public URL pointing at their local JS app. Also trigger when they reference remote-connect / SSH-from-phone scenarios and need a way to hit their dev server. Don't wait for the exact word "ngrok" — any "expose / share / tunnel / public link / mobile preview" intent in a Node/JS project should trigger this.

Fetch and address GitHub PR review comments for the current branch. Trigger when: user asks to "address PR comments", "fix review feedback", "handle PR reviews", "review-pr", "address review", "fix PR comments", or any request to act on pull request review feedback. Also trigger when the user pastes a PR URL and asks to address its comments.

Full browser automation via Agent Browser Protocol (ABP). Navigate, click, type, scroll, drag, screenshot, extract text, handle dialogs/downloads/file pickers, manage tabs, control JS execution. Single CLI tool.

Performance engineering guidance for CPU and memory optimization across languages (Rust, C/C++, TypeScript/JavaScript, Go, Python). Use this skill whenever the user asks about optimizing code performance, reducing memory allocations, improving cache locality, SIMD/vectorization, profiling, benchmarking, or any question about making code faster or more memory-efficient. Also trigger when the user mentions: hot loops, allocation pressure, cache misses, false sharing, memory pools, arena allocation, string interning, branch prediction, auto-vectorization, zero-copy, AoS vs SoA, data-oriented design, or profiling tools (perf, flamegraph, Instruments, VTune, cachegrind). Trigger even for indirect performance questions like "why is this slow", "this function is a bottleneck", "how to reduce memory usage", or "should I optimize this".
