+# AGENTS.md
+
+## Repo Snapshot
+- Repository: `jtgsystems/Phone-Control-Project`
+- Default branch: `main`
+- Visibility: `public`
+- Summary: Phone control system - Remote device management & automation
+- Detected stack: Node.js, Python
+
+## Read First
+- `README.md`
+- `CLAUDE.md`
+- `package.json`
+- `requirements.txt`
+- `.github/workflows/`
+
+## Key Paths
+- `src/`
+- `Software/`
+
+## Working Rules
+- Keep changes focused on the task and match the existing file layout and naming patterns.
+- Update tests and docs when behavior changes or public interfaces move.
+- Do not commit secrets, credentials, ad-hoc exports, or large generated artifacts unless the repository already tracks them intentionally.
+- Prefer the existing automation and CI workflow over one-off commands when both paths exist.
+- Legacy agent guidance exists in `CLAUDE.md`; keep it aligned with `AGENTS.md` if those files remain in use.
+
+## Verified Commands
+- Install: `npm install`
+- Dev: `npm run dev`
+- Build: `npm run build`
+- Test: `npm test`
+
+## Change Checklist
+- Run the relevant tests or static checks for the files you changed before finishing.
+- Keep human-facing docs aligned with behavior changes.
+- If the repo has specialized areas later, add nested `AGENTS.md` files close to that code instead of overloading the root file.
+
+## Notes
+- CI source of truth lives in `.github/workflows/`.
+
+This file should stay short, specific, and current. Update it whenever the repo's real setup or verification steps change.
