Principle Performance

Category: Engineering · Sub-category: performance · Last updated: 2026-05-21

type:review

Performance engineering principles — latency vs throughput, profile-before-optimize discipline, Big-O instincts for common patterns, allocation and GC pressure, data locality and cache-friendliness, N+1 queries on a list endpoint. Auto-load when reviewing hot-path code, choosing data structures, designing batch or streaming pipelines, hunting allocations or GC pauses, weighing latency trade-offs, considering caching, detecting N+1 queries on list endpoint calls, or evaluating scalability.

From the source SKILL.md

Performance bugs are design bugs. They are cheapest to fix before the first line of code is written. This skill teaches design-time discipline — choosing the right algorithm, data structure, and access pattern — not runtime profiler operation.

What this skill does

Principle Performance is a community-contributed Claude Code skill in the performance sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/principle-performance/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Principle Performance Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
