Cause (Documented platform behavior): Vercel CLI needs a user token; in non-terminal contexts it cannot run the interactive login. Fix status: documented_behavior Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/vercel/vercel/c628be7835e03a965b93e9cf9e2bd5ac2acbf5eb/packages/cli/src/util/login/prompt-missing-credentials.ts (official_docs, unknown, documented_behavior): Outside CI with a TTY or agent it starts login; otherwise prints 'No existing credentials found. Please run vercel login or pass --token'. - https://raw.githubusercontent.com/vercel/vercel/c628be7835e03a965b93e9cf9e2bd5ac2acbf5eb/errors/no-credentials-found.md (official_docs, unknown, documented_behavior): Error doc: running in a non-terminal context without credentials; fix by --token or vercel login.

Recommended action: Create an access token and pass it with --token (e.g. `vercel deploy --token $VERCEL_TOKEN`) in CI; locally run `vercel login`. Option: Pass a token [evidence: official_recommended_action] Applies when: See record scope. Steps: 1. vercel pull --yes --token $VERCEL_TOKEN 2. vercel deploy --token $VERCEL_TOKEN Expected: Command proceeds without the error. Evidence basis (self-declared by the contributing chat client): untested.
