agent-control-spec 0.4.0a1

Agent Control Specification: a stateless policy decision runtime implementing the agent-hooks interceptor contract.

agent-control-spec (Python)

Python binding for the Agent Control Specification runtime: a stateless policy decision engine that plugs into any agent-hooks host as an interceptor.

pip install --pre agent-control-spec

from agent_hooks import InterceptionEmitter, EnforcementMode
from agent_control_spec import AcsInterceptor

emitter = InterceptionEmitter(mode=EnforcementMode.ENFORCE)
emitter.register(AcsInterceptor("manifest.yaml"), "acs")

The manifest binds policies (Rego through OPA, Cedar through the built-in evaluator, or test doubles) to interception points; the runtime evaluates each context and returns an agent-hooks verdict. Engine failures never raise into the host loop: they normalize into fail-closed deny verdicts with runtime_error:* reasons.

Trust model: a cooperative contract, not a security boundary — the host is fully trusted. See the repository's SECURITY.md.
