+# AGENT Instructions for Meshtastic Linux Client
+
+## Required Checks
+- Run `flake8` for style and syntax errors.
+- Execute `bandit -r . -n 5` for basic security scanning.
+- Validate markdown docs with `mdl README.md docs/README.md`.
+- Build packaging artifacts using:
+  - `fpm -s dir -t deb -n meshtastic-client -v 1.0 --prefix=/opt/meshtastic-linux-client .`
+  - `fpm -s dir -t rpm -n meshtastic-client -v 1.0 --prefix=/opt/meshtastic-linux-client .`
+
+## Pull Request Notes
+Summarize significant changes and include the test results output. If package or test commands fail due to missing dependencies or network limits, mention that in the Testing section.
