Diagnostics

Run the main diagnostic command from the project root:

carbon doctor

Doctor validates manifest shape and consistency, plugin platform support, security scopes, mobile permissions, updater configuration, and native toolchain readiness. Warnings identify risky defaults; errors produce a non-zero exit code for CI.

Check signing separately:

carbon doctor signing

Validate capability names and command patterns:

carbon capabilities check

Inspect generated platform drift:

carbon platform list

Preview a bundle plan without executing it:

carbon bundle desktop --dry-run
carbon bundle android --dry-run
carbon bundle ios --simulator --dry-run

When filing a build issue, include the target, Carbon version, .NET SDK and workload versions, active Xcode or Android SDK version, and the first native toolchain error rather than only the final exit code.
