Development

New Apps

Use CONTRIBUTING.md as the SPOT for the general development workflow, testing, review, and coding standards.
Treat the matching Pull Request template described in Pull Requests and stored in PULL_REQUEST_TEMPLATE as the SPOT for requirements, file checks, validation expectations, and the Definition of Done.
Start from the smallest app-specific change that can be validated locally, then expand only when the requirements or behavior demand it.
Keep the implementation, local validation, and PR template in sync so the app can be reviewed without guessing the intent.

Treat warnings about the concrete implementation, wiring, or runtime behavior as bugs that should be fixed.
Do not leave implementation warnings unresolved just because they are inconvenient.
If a warning points to an intentional exception, make the exception explicit and keep the follow-up visible.

When a development run fails, switch to Debugging and follow the local-deploy or GitHub-log path that matches the failure source.
Keep long-running runs alive and wait for them to finish unless the user explicitly asks you to steer away from them.

Ask whether the new app behaves correctly end to end, not just whether it compiles or deploys.
Prefer fixing the real app bug over adding a comment that explains it away.
Treat temporary warnings as a signal to remove the underlying problem later, not as a reason to normalize the exception.
