biome-developer

Curated third-party skill source. Run /review source before repo promotion.

Quick Start

Install:

npx skills add biomejs/biome --skill biome-developer -y -g -a antigravity claude-code codex crush cursor gemini-cli github-copilot grok opencode

Use: /biome-developer

Works with Claude Code, Gemini CLI, OpenCode, and other agentskills.io-compatible agents.

Curated external (hand-maintained)

Composed compose-external-wave-2 using authoring SSOT (docs/src/authoring/skills/biome-developer.mdx) + research. Do not run wagents docs generate on this file (HAND-MAINTAINED sentinel). Run /review source before using in production or promoting.

What It Does

biome-developer supplies internal best practices and gotchas for contributors working on the Biome (formatter/linter) codebase itself. It covers AST navigation, string extraction without allocation, embedded language handling, clippy/style rules (no emojis, let chains, path imports), dev-dependency path usage, comment guidelines, testing via quick_test, and common API confusion tables. Marked as compatibility: “Designed for coding agents working on the Biome codebase (github.com/biomejs/biome).”

Harness Coverage

Targets verified harnesses: antigravity, claude-code, codex, crush, cursor, gemini-cli, github-copilot, grok, opencode.

Portable multi-harness install command:

npx skills add biomejs/biome --skill biome-developer -y -g -a antigravity claude-code codex crush cursor gemini-cli github-copilot grok opencode
