Use when measured CPU, GPU, memory, allocation, streaming, or frame-pacing data misses an existing performance budget and the bottleneck must be isolated before changing quality or gameplay code.
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.

# Performance optimization
Consume the targets and measurement setup from `performance-budget`; this skill does not invent a second budget.
## Diagnose the critical path
1. Reproduce the miss with the same device/build/scene/settings used by the budget.
2. Inspect p50/p95/p99 frame-time and hitch traces, not only averages.
3. Determine whether the present interval is CPU-bound, GPU-bound, synchronized/stalled, allocation/GC-bound, streaming/IO-bound, or memory-pressure-driven.
4. Within the failing side, find the dominant critical-path bucket before selecting a lever.
5. Change one bounded cause, rerun the identical capture, and compare both the target metric and guardrails.
CPU and GPU timings overlap; optimize the path that gates presentation rather than summing unrelated buckets. A GPU reduction does not improve frame time when the frame is still CPU-bound, and vice versa.

The line at the top of this page pins the label git:20260913.9374bb1, 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.
