Start with the symptom you can observe. Record the project, file, app mode, exact message, action, and whether the failure affected project content or an external destination before retrying.
Problem area: Install, sign-in, profiles, projects, or invitations · Start here: Installation and login
Problem area: Agent cannot connect, select a project, or reach the app host · Start here: MCP connection
Problem area: Canvas, Preview, responsive, interaction, or rendering mismatch · Start here: Preview and rendering
Problem area: Generated code, dependencies, local export, Git, or consumer build · Start here: Export and build
Problem area: Incoming/outgoing changes, push, conflict, or history recovery · Start here: Synchronization
Problem area: API, Storage, Content, database, authentication, or access · Start here: Data and API
Save the exact error text or screenshot.
Confirm the current project, file, target, Preview identity, and destination.
Decide whether the failed action was a read, a project-content write, or an external side effect.
Reread current state; do not assume a failed or warning result changed nothing.
Make one correction and rerun the smallest reproduction.
If recovery could delete data, overwrite a destination, publish, push, or call a real write API, stop and inspect the specific recovery section first.
