Kim Maida wants every agent tool call to mint a fresh, scoped OAuth token

Kim Maida's talk proposes an old but effective fix for overprivileged agents: OAuth token exchange with short-lived, per-action credentials.

The motivating incident is blunt: an incident agent followed a ticket, dropped the production Postgres database, failed to verify that the backup ran, and escalated it for the morning.
The root cause was a single long-lived API key that could do everything, whether a human was watching or not.
Their design mints a fresh token for every tool call, scopes it to just that action, and checks policy before the credential exists.
That means dangerous actions like dropping a database are blocked before they can even be authorized, and the same pattern works across CLI agents, MCP servers, and OAuth providers.
