Global flags

These flags are registered globally by the CLI parser (packages/cli/src/context/parser.ts) and accepted on every command.

Flag	Description
`--help`, `-h`	Show help for the current command and exit.
`--version`, `-v`	Print the installed CLI version and exit.
`--no-telemetry`	Disable anonymous telemetry for this run. See Telemetry.
`--telemetry-debug`	Print telemetry events to stderr instead of sending them.
`--logger <level>`	Set log level (`fatal`, `error`, `warn`, `info`, `debug`).
`--config <path>`	Load configuration from an explicit file.
`-y`, `--yes`	Skip confirmation prompts (use with caution).

--dry-run is not global; the codemods command accepts it as a per-command flag — see codemods.

Environment variables

Variable	Effect
`C15T_TELEMETRY_DISABLED=1`	Permanently disable telemetry for this user.
`C15T_DEBUG=1`	Enable verbose debug logs.
`C15T_URL`	Override the backend URL the CLI talks to (the value read by `ENV_VARS.BACKEND_URL` in `packages/cli/src/constants.ts`).
`C15T_API_KEY`	API key passed to the backend (read by `ENV_VARS.API_KEY`).
`CONSENT_URL`	Override the control-plane / dashboard base URL (used for `login`).
`NO_COLOR=1`	Disable terminal colors.

Exit codes

Code	Meaning
`0`	Success.
`1`	General error (failed command, validation error).
`2`	Usage error (invalid flags or arguments).
`130`	Interrupted (Ctrl-C).
