This release is a pre-release and may not be stable for production use.
agent-hooks (Python SDK)
Python implementation of
AGENT-HOOKS-0.1:
interception-point enums, AgentContext builder, Verdict types, host-side
InterceptionEmitter with the four composition profiles, the pluggable
identity-provider seam, and the Conformance Test Kit.
Trust model. agent-hooks is a cooperative contract, not a security boundary: the host framework is fully trusted, interceptors run in-process with full data access, and no complete-mediation claim is made. Read SECURITY.md and spec §1.4 before relying on it.
pip install --pre "agent-hooks-sdk[ctk]"
# import name: agent_hooks
Host (framework adapter) usage
from agent_hooks import AgentContextBuilder, InterceptionBlocked, InterceptionEmitter
builder = AgentContextBuilder(agent_id="my-agent", framework="my-fw", session_id="s-1")
emitter = InterceptionEmitter().register(MyPolicy())
await emitter.emit(builder.agent_startup(tools_registered=["http_get"]))
ctx = builder.pre_tool_call(call_id="tc-1", name="http_get", args={"url": url})
try:
await emitter.emit(ctx)
except InterceptionBlocked as e:
return tool_error(e.result.verdict.reason)
result = invoke_tool(ctx["tool_call"]["args"]) # post-transform args
Interceptor usage
from agent_hooks import AgentContext, Verdict
class MyPolicy:
def intercept(self, ctx: AgentContext) -> Verdict:
if ctx["interception_point"] == "pre_tool_call" and ctx["tool_call"]["name"] == "rm":
return Verdict.deny(reason="dangerous")
return Verdict.allow()
Verdict.allow(), Verdict.deny(...), Verdict.warn(...) (allow + recorded
warning) and Verdict.escalate(...) (liftable deny for the approval seam, §9)
are the constructor shortcuts for the §5 shapes.
Running the CTK against your framework
Implement agent_hooks.ctk.Harness (see
conformance/HARNESS.md),
then:
pytest --agent-hooks-harness=my_pkg:MyHarness
The vectors ship inside the wheel; pass --agent-hooks-vectors=<dir> only to
run a different vector set.
