name: code-formatting description: Format code on the current branch using Biome. Use when asked to format, lint, or clean up code before committing or creating a PR.

Code Formatting

Format JS/TS/JSON files changed on the current branch using Biome.

Quick Usage

Copy.claude/skills/code-formatting/scripts/format-branch.sh

This formats all .js, .ts, .jsx, .tsx, .json, .jsonc files changed compared to main.

Custom Base Branch

Copy.claude/skills/code-formatting/scripts/format-branch.sh develop

What It Does

1. Finds files changed on current branch vs base branch
2. Filters to JS/TS/JSON files only
3. Runs npx biome check --write on those files
4. Uses same settings as the biome-check.yml CI workflow

Config

Biome config is at biome.jsonc in repo root.

Notes

• Run from repo root
• Requires Node.js/npx
• Only formats changed files (not entire codebase)
