UnYOLO: Agent credential broker and policy engine for your GitHub account

unYOLO is a framework that acts as a credential broker and policy engine for GitHub and other services, allowing agents to request permissions through the broker rather than holding actual credentials. Instead of giving agents full account access, unYOLO enforces fine-grained policies defined in a local file, with support for time-limited and single-use grants that require operator approval. This approach prevents unauthorized operations by keeping the provider token isolated in a separate process and validating all agent requests against defined policies before execution.
