+# Agent Guidelines
+
+Instructions for AI agents working on this repository.
+
+## Branch Naming and Commit Conventions
+
+Branch names must use a conventional commit prefix (e.g., `feat/`, `fix/`, `chore/`). This is enforced by CI. See `CONTRIBUTING.md` for the full list of allowed types and commit message format.
+
+## Do Not Commit Build Artifacts
+
+The `dist/` folder, `CHANGELOG.md`, and version bumps in `package.json`/`package-lock.json` are all generated by the CI/CD release process. Only commit changes to source (`src/`) and test (`test/`) files.
+
+## Git Push (SAML SSO)
+
+The `mparticle-integrations` GitHub org enforces SAML SSO. SSH push will fail. To push:
+
+1. Run `gh auth setup-git` to configure the git credential helper.
+2. Temporarily switch the remote to HTTPS: `git remote set-url origin https://github.com/mparticle-integrations/mparticle-javascript-integration-rokt.git`
+3. Push the branch.
+4. Restore the SSH remote: `git remote set-url origin git@github.com:mparticle-integrations/mparticle-javascript-integration-rokt.git`
+
+## Running Tests
+
+```bash
+npm install
+npm test -- --browsers ChromeHeadless  # FirefoxHeadless may not be available
+```
+
+## Linting
+
+```bash
+npm run lint       # check
+npm run lint:fix   # auto-fix
+```
+
+Always run lint before pushing. The CI enforces Prettier formatting.
