# Cargo CLI — Diagnostics Forensic runbooks for workflow behavior: trace one run, sweep a batch for errors, profile a play's credit spend. This skill is the **interpretation layer** — the raw surfaces (`run get`, orchestration SQL, billing metrics) are documented in `cargo-orchestration` and `cargo-billing`; each runbook here tells you which of them to pull, in what order, and what each output shape means. ## Bootstrap Already signed in (`cargo-ai whoami` returns a workspace)? Skip to the next section. ```bash npm install -g @cargo-ai/cli # no global install? prefix every command with `npx @cargo-ai/cli` cargo-ai login --email you@company.com # emailed code, no browser; creates the account on first use # alternatives: --oauth (browser) · --token <api-token> (CI) cargo-ai whoami # confirm the active workspace before any write ``` Every command prints JSON to stdout; failures exit non-zero with `{"errorMessage": "..."}`. Anything that creates a run or a batch is async — pass `--wait-until-finished` or poll the matching `get`. Credit attribution steps (`billing usage get-metrics`, `billing subscription get`) need a token with **admin access**; everything else works with a standard token. When the full skill bundle is installed, [`../cargo/references/prerequisites.md`](../cargo/references/prerequisites.md) adds the CLI version pin, token scopes, and the admin-only surface. ## Which runbook? ``` Wha...
