App Store Connect CLI reference for command discovery, flags, output formats, and authentication.

• Use --help at any level (asc --help, asc builds --help, asc builds list --help) to discover available commands and flags
• Output adapts to context: defaults to table in interactive terminals and json when piped; use --output table or --output markdown for explicit human-readable formatting
• Destructive operations require --confirm flag; use --paginate to retrieve all pages of results
• Authenticate via keychain with asc auth login, or set environment variables (ASC_KEY_ID, ASC_ISSUER_ID, ASC_PRIVATE_KEY_PATH, etc.); ASC_APP_ID provides a default app
• Control request and upload timeouts with ASC_TIMEOUT and ASC_UPLOAD_TIMEOUT environment variables
