The kill switch
for your AI.

Agents hallucinate. Loops spiral. Budgets bleed.
Agent Sentinel kills the process before your card hits the limit.

Autonomous agents are dangerous. They get stuck in loops. They call expensive APIs 500 times in a second. They delete the wrong rows.
We built the Circuit Breaker. A local-first, zero-latency SDK that enforces hard limits on cost, recursion, and policy.

5ms Overhead.
Total Traceability.

Install the SDK. Decorate your functions. We intercept execution, check the ledger, and kill the process if policy is violated. It happens locally, in microseconds.

✅ Works with LangChain
✅ Works with CrewAI
✅ Works with AutoGen
✅ Works with raw Python
from agentsentinel import guarded_action

@guarded_action(
    name="send_email",
    max_cost_usd=0.05,
    policy="no_external_domains"
)
def send_email(to, body):
    # If this exceeds budget, it never runs.
    # The ledger records the attempt locally.
    client.send(to, body)

The Safety Stack

🛡️

Hard Stops

Define strict budgets per run or per action. If an LLM tries to spend $10 on a loop, we kill it at $1.

📼

Deterministic Replay

Replay any agent run offline using cached outputs. Debug logic without spending tokens or hitting live APIs.

📝

Local Ledger

An append-only, JSONL record of every decision, input, and cost. Audit-ready and human readable.

Operational Certainty

Initialize the sentinel before you ship to production.
