AffixIO ADK guard
Fail-closed authorization for Python functions exposed as Google Agent Development Kit tools.
from affixio_adk import AffixIOAuthorizer
auth = AffixIOAuthorizer("aio_...", agent_id="my-agent")
@auth.tool
def update_ticket(ticket_id: str, status: str):
return update_system(ticket_id, status)
Only an explicit allow decision executes the function. deny, review, malformed decisions, and authorization failures do not execute it. The wrapper is compatible with ADK's Python function-tool pattern and does not require private prompts, credentials or operator identity in the decision payload.
Install with pip install affixio-adk[google]. The Google ADK dependency is optional because the guard is deliberately a normal callable wrapper, making it easy to test before wiring it into an ADK Agent.
Google ADK example
See examples/basic_agent/agent.py. It registers an ordinary protected Python function as an ADK LlmAgent tool. The wrapper executes only after an explicit allow decision. review is treated as blocked and must be handled by a separate approval flow.
The repository includes CI for Python 3.10 through 3.13 and a package-build check. Live API tests are intentionally opt-in so CI never consumes proofs or requires production credentials.
