OAuth token revoked
OAuth token has expired
Invalid API key

What it means

Claude Code cannot use the current local credential. The token may be expired, revoked, tied to a disabled organization, or shadowed by the wrong API key environment variable.

Most common causes

Browser login completed but the CLI token cache stayed stale
ANTHROPIC_API_KEY points to the wrong key
A corporate proxy or browser profile blocked OAuth callback
The account or organization no longer has access

Fastest fix

Run /logout, close Claude Code, then run claude and login again
Check whether ANTHROPIC_API_KEY is set in the terminal
Try a clean browser profile for the OAuth flow
If the local auth file is corrupt, remove only the Claude Code auth file and login again

Safe fix

Use organization-managed keys for CI, not personal browser OAuth
Store keys in a secret manager or shell profile with limited scope
Keep browser and terminal on the same user account
Document which auth mode each machine uses

What not to do

Do not paste OAuth tokens into project config
Do not commit auth.json or shell history
Do not use sudo to force npm or auth paths

How to confirm the fix

Run the smallest reproducible command first, then retry the agent task only after authentication, quota, and tool discovery are stable.
