@lssm/action.pr

Website: https://contractspec.io

GitHub Action that runs ContractSpec validation checks on pull requests. Posts drift reports, validation results, and product views as PR comments.

What It Does

• Uses @lssm/lib.contracts-spec for contract definitions
• Uses @lssm/bundle.workspace for workspace analysis
• Configured via action.yml; no src/ — logic lives in workspace bundle

Usage

name: ContractSpec PR
on: pull_request
jobs:
  contractspec:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      packages: read
      pull-requests: write
    steps:
      - uses: actions/checkout@v6
      - uses: lssm-tech/contractspec/packages/apps/action-pr@main
        with:
          github-packages-token: ${{ secrets.CONTRACTSPEC_PACKAGES_TOKEN }}
          generate-command: 'bun contractspec generate'

For affected private GitHub Packages dependencies, github-packages-token must be a GitHub token that can read the ContractSpec packages granted to the consuming repository, bot, or GitHub App.
