Core Web Vitals discipline for agent-built pages: LCP, CLS, INP budgets, font loading that doesn't shift layout, images that don't bloat, CSS/JS that doesn't block. A designed page that loads like a template is half a page. Use when generating or auditing any web page or component. Stack on the design-taste core skill.
Runs the react-doctor scanner on a React package, fixes its error diagnostics, and re-runs until none remain. Use when the user says "health-check the React code", or when React components or hooks changed, when finishing a React feature or bug fix, or when asked to health-check React code.
Audit the last N days of agent transcripts across every project at once and find where wall-clock, tokens, and repeated human corrections are going. A zero-dependency script mines every transcript into five fact tables and prints a summary; the model reads the numbers, digs into the tables, and returns a ranked, copy-pasteable list of fixes to the repo, the config, and the rules files.
Audits Android codebases for ANR risks and diagnoses ANR stack dumps. Use this skill when scanning Android code for ANR risks or triaging ANR stack dumps. Don't use for non-ANR crashes, dropped frames, general CPU profiling, or Perfetto system traces.
OpenMP skill for shared-memory parallel programming. Use when writing parallel for loops, reductions, task parallelism, SIMD directives, GPU offloading, or profiling with Score-P/TAU. Activates on queries about OpenMP, pragma omp, schedule static dynamic, reduction, false sharing, or OMP_NUM_THREADS.
Compute-planning rules. Use before launching any calculation whose runtime is not already measured — and whenever an agent proposes a long run, an overnight grind, or a bigger machine as the way forward.
Performance diagnosis and optimization - MicroProfiler, Script Profiler, Developer Console, Scene Analysis, Luau heap and memory categories, memory leaks, network/replication cost, rendering and physics cost, streaming, native codegen, Parallel Luau with Actors. Use when a game lags, stutters, drops FPS, crashes on mobile, has high ping, or before optimizing hot code.
Test, debug, or profile Roblox experiences. Use for Studio debugging, TestEZ, logging, connection cleanup, memory or network diagnostics, MicroProfiler, Scene Analysis, and Script Profiler.
Expert guidance on Webflow CMS architecture and best practices. Use when planning collections, setting up relationships, optimizing content structure, or troubleshooting CMS issues.
Set up, operate, tune, and troubleshoot Minecraft Java 26.x and legacy 1.21.x servers across Paper, Purpur, Folia, Velocity, Fabric, and NeoForge. Use for infrastructure, backups, proxies, and live operations, not plugin or mod development.
Use when writing, reviewing or debugging Luau in a Roblox experience: task.spawn vs task.defer vs task.wait, replacing wait() or spawn(), Deferred events and SignalBehavior, handlers running in the wrong order or not at all, 'attempt to yield across metamethod/C-call boundary', --!strict and the new type solver, typed classes and metatables, Destroy and cleanup, 'server memory keeps growing' or memory leaks, Parallel Luau with Actors and SharedTable, 'not safe to write in parallel', --!native or 'make this script faster', buffers, coroutines.
Use when reviewing, debugging, or optimizing Luau scripts written directly in Roblox Studio (no Rojo, no VS Code) - memory leaks, dangling connections, client/server mistakes, exploitable RemoteEvents, lag from wait() or polling loops, animation scripts that stutter or stack, DataStore data loss, or "why does my script break on respawn / when a player leaves".
