Every AI action.
Provable.
Your AI agents make hundreds of decisions a day. If an auditor asks to see the record — what do you show them? Sentinel logs every action automatically, so your compliance team always has an answer.
● Live event stream
How it works
Three lines of code.
Complete accountability.
Wrap
Install the SDK and wrap your agent with one decorator. Zero changes to your agent logic.
@sentinel.wrap("paybot", "invoke")Log
Every invocation fires a non-blocking event to Sentinel. Your agent never waits.
POST /v1/events → 202Prove
Every event is chained with a SHA-256 hash. Tamper one record and the chain breaks.
hash: b72e3f...04afTamper-proof record
Every event links to the last.
Deletion is detectable. Reordering is detectable.
Built for compliance
The audit trail your
legal team will actually trust.
Hash-chained events
SHA-256 chain links every event. Any mutation or deletion breaks the chain instantly.
Non-blocking SDK
Events fire in daemon threads. Your agent never waits for Sentinel. Zero latency impact.
Flag & escalate
Mark events for review. Compliance officers see the full audit trail — plain-English summaries coming soon.
PDF audit reports
One-click PDF exports of any time range, ready for auditors and regulators.
Role-based access
Engineers see raw events. CCOs see summaries. Nobody sees what they shouldn't.
Python & Node SDKs
pip install sentinel-agent-sdk or npm i sentinel-agent-sdk. Works with any agent framework.

Ship AI agents
your auditors can verify.
Regulators are asking about AI systems. The question isn't whether they'll ask about your agents' decisions — it's whether you'll have records when they do.
