Enforce universal standards for high-performance development. Use when profiling bottlenecks, reducing latency, fixing memory leaks, improving throughput, or optimizing algorithm complexity in any language.

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.

What the file says

# Performance Engineering Standards

## **Priority: P0 (CRITICAL)**

## Workflow

1. **Baseline**: Profile before changing anything — measure CPU, memory, and latency.
2. **Identify**: Find top bottleneck (N+1 query, hot loop, memory leak).
3. **Fix**: Apply targeted optimization from sections below.
4. **Verify**: Re-profile to confirm improvement and check for regressions.

## Resource Management

- **Memory Efficiency**:
 - Avoid memory leaks: explicit cleanup of listeners, observers, and streams.
 - Optimize data structures: `Set` for lookups, `List` for iteration.
 - Lazy Initialization: Initialize expensive objects only when needed.
- **CPU Optimization**:
 - Aim for O(1) or O(n); avoid O(n^2) in critical paths.
 - Offload heavy computations to background threads or workers.
 - Memoize pure, expensive functions.

See [implementation examples](references/implementation.md) for memoization and batching patterns.

## Network & I/O

- **Payload Reduction**: Use efficient serialization (Protobuf, JSON minification) and compression (gzip/br).
- **Batching**: Group multiple small requests into single bulk operations.

How to install

The exact contents, by fingerprint
mdr add hoangnguyen0403/agent-skills-standard/common-performance-engineering@sha256:e170a05495ec3d9e

The line at the top of this page pins the label git:20261026.f9fb5eb, 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.
