Systems

Internal Go packages that are not commands but underpin them. Most of these are reused across the entire pkg/cmd/ tree.

Pages

• API client - api/: REST + GraphQL on top of cli/go-gh.
• Factory and cmdutil - pkg/cmdutil/ and pkg/cmd/factory/: dependency injection.
• IOStreams - pkg/iostreams/: terminal abstraction.
• HTTP mocking - pkg/httpmock/: testing infrastructure.
• Extension manager - pkg/cmd/extension/manager.go.
• Codespaces runtime - internal/codespaces/.
• Git client - git/: shells out to git.
• Config and auth - internal/config/, internal/authflow/, internal/keyring/.
• Prompter and survey - internal/prompter/.
• Feature detection - internal/featuredetection/.
• Telemetry and skills - internal/telemetry/, internal/barista/, internal/skills/.
