performance loops
5 loops in this category.
Benchmark regression watch
Run the benchmark suite every 30 minutes during active development and raise a flag the moment any benchmark slips more than 5 percent from baseline.
/loop 30m run `npm run bench`, compare each result to the baselines in bench/baseline.json, and if any benchmark regressed more than 5%, show me the numbers and the commits since the last clean run

AutoLoop — metric-driven optimization loops
Agent-agnostic hill-climbing loops inspired by Karpathy's autoresearch: define a metric, let the agent propose a change, measure, keep it only if the number improved, and repeat.
Iterative optimization loops (inspired by Karpathy's autoresearch): define a metric, agent proposes change, harness measures, keep if improved, repeat. Works with Claude Code, Codex, Cursor, Gemini CLI.

Bundle size budget
Shrink the production JavaScript bundle under a hard budget by attacking the largest modules with code-splitting, lighter imports, and dead-weight removal.
/goal the main production bundle is under 250 KB gzipped — run the build with the bundle analyzer, address the single largest contributor each turn (code-split it, replace it with a lighter import, or drop it), and confirm the build and tests stay green; stop at the budget or after 10 turns

Hold a stable frame rate
Measure frame time, CPU, GPU, and memory under fixed conditions and keep only regression-free optimizations.
Improve the frame-rate stability of [game or interactive build]. Before editing, define one repeatable benchmark with the same scene, inputs, hardware, build, resolution, and settings. If no scenario or targets are supplied, propose representative values and state them before proceeding. Record frame-time distribution, average FPS, minimum FPS, CPU use, GPU use, and memory behavior. Identify the largest measured bottleneck and make one focused optimization. Rerun the complete benchmark under the same conditions. Keep the change only if it improves the target without regressing another metric or changing expected behavior. Repeat until [FPS target] holds for [stability period] with no dip below [FPS floor], memory remains below [memory target] without an upward trend, and CPU stays below [CPU target] across two consecutive runs. Stop on success, two rounds without measurable progress, a blocker, or [iteration budget]. Finish with the benchmark setup, before-and-after measurements, retained changes, reverted attempts, and remaining bottlenecks.

Get every page under 50 ms
Benchmark each page with one repeatable measure and keep optimizing until every target loads under the threshold.
Continue optimizing the code for speed. After each significant change, measure page-load performance across every page under the same repeatable test conditions. Continue until every page loads in under 50 ms.
