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

This formats all .js, .ts, .jsx, .tsx, .json, .jsonc files changed compared to main.
Custom Base Branch
.claude/skills/code-formatting/scripts/format-branch.sh develop
What It Does
- Finds files changed on current branch vs base branch
- Filters to JS/TS/JSON files only
- Runs
npx biome check --writeon those files - Uses same settings as the
biome-check.ymlCI 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)
