Prettier Format (is-kit)

Overview

Format or check code using this repo's Prettier configuration and ignore rules. Prefer local binaries and the project's package manager.

Workflow

  1. Read repository instructions.
  • Open AGENTS.md in the repo root and follow all constraints (commands, formatting, tests, etc.).
  • If AGENTS.md is missing, ask how to proceed.
  1. Determine intent and scope.
  • Use --check for "verify formatting" requests.
  • Use --write for "format" or "fix" requests.
  • Ask for target paths when not specified; do not assume whole repo unless requested.
  1. Run Prettier with local tooling.
  • Prefer ./node_modules/.bin/prettier.
  • Alternative: pnpm prettier (repo uses pnpm).
  • Avoid npx unless the user explicitly approves network downloads.
  1. Report results.
  • Summarize changed files or confirm a clean check.
  • If a command fails, include the error and propose the next step.

Quick Commands

  • Format repo: ./node_modules/.bin/prettier --write .
  • Check formatting: ./node_modules/.bin/prettier --check .
  • Format paths: ./node_modules/.bin/prettier --write src tests
  • Check paths: pnpm prettier --check src tests
