Skill v0idOS/performance-deity/skills/build

A ruthlessly strict algorithmic optimization methodology for AI coding agents. Forces your agent to profile, benchmark, and mathematically prove performance gains before writing code.

What its author says it does

Copied from the file, not written here

Reduce CI/CD build times. Analyzes Dockerfiles, Webpack/Vite configs, and GitHub Actions workflows to identify the slowest step and apply targeted caching and build optimizations.

Execute all three phases in order.

Phase 1 — Bottleneck

Analyze whichever config file applies:

Dockerfile
webpack.config.js / vite.config.ts
.github/workflows/*.yml

Identify the single step that consumes the most wall-clock time.

Phase 2 — Fix

Docker:

Reorder layers: least-changing first (OS deps, runtime), most-changing last (app code).
Use multi-stage builds: compile in a full image, copy only the output artifact into a minimal runtime image (e.g. alpine).

Webpack / Vite:

Enable code splitting and tree-shaking.
Enable TerserPlugin with parallel: true.
Set cache: { type: 'filesystem' } for persistent build caching.

GitHub Actions:

Cache node_modules using actions/cache keyed on the hash of package-lock.json.
Cache pip packages keyed on the hash of requirements.txt.
Add concurrency: groups to cancel in-progress runs on force-push.

Phase 3 — Report

State: "This change will save approximately X minutes per PR run" with explicit reasoning.
