Crimp is an open-source decision gate for AI agents. The agent brings the rule and the facts, never a conclusion. The rule is sealed before anyone knows the outcome, and Crimp keeps watching the facts it stood on.
Here, a benefit-eligibility rule and three facts about one household.
Rule v3 received, not sealed
Decision · example — waiting for the rule
If an agent tries to hand over its own verdict, Crimp refuses it. Agents bring facts, not verdicts.
Rule v3 received, not sealed
Decision · example — the agent’s verdict is refused
Nobody can tune the rule after they’ve seen which way it goes.
Rule v3 sealed · example seal 9f3c·a07e·51d2·e21a
Decision · example — rule sealed · outcome unknown
Each fact is crimped to the decision it supports, so the decision always knows what it stands on.
Rule v3 sealed
Decision · example APPROVED 3 facts crimped
When a fact stops holding, nobody has to remember to go back. The decision pulls itself and asks again.
Rule v3 sealed
Decision · example WITHDRAWN fact 2 broke · deciding again
Asked again, one fact comes back unknown. The wax stays soft: the decision waits for the fact instead of collapsing into a no.
Rule v3 sealed
Decision · example NOT SEALED waiting for fact 3
Benefits. Coverage. Prior authorisation. When an automated system says yes or no to a person, that answer should come with its rule, its facts, and a way to take it back the moment it stops being true.
Crimp is built for the teams that run those decisions and the people who have to answer for them.
Patent pending. The code stays open.

A decision gate takes the decision away from the agent. With Crimp, the agent submits the rule it is applying and the facts it is applying it to, never a conclusion. Crimp evaluates the rule and works out the outcome. There is no field in which an agent can assert a verdict.
Crimp is an open-source decision gate from Deimos AI LLC: Apache-2.0, signed v0.1.0 release published 13 Sep 2026, and the OpenSSF Best Practices Silver badge (project 14613). Read the source on GitHub.
So nobody can tune the rule after seeing which way it goes. A sealed rule can be re-run against the sealed facts years later and give the identical answer, which makes every decision reproducible.
The decision withdraws itself. Crimp re-evaluates the sealed rule against fresh facts; if it no longer holds, the seal lapses and the decision asks again. Nobody has to remember to go back.
“We don’t know” is not “no”. A missing fact leaves the decision open; it never quietly collapses into a denial, or into an approval.
It can propose a bad rule, and a bad rule is visible, reviewable and reproducible in a way a bad conclusion never is. Crimp holds no credentials, has no outbound access and executes nothing: it reports what stands, and the caller decides what to do.
Decisions that change someone’s week: benefits, coverage, prior authorisation. Wherever an automated system says yes or no to a person, the answer should carry its rule, its facts, and a way to take it back the moment it stops being true.
A US provisional patent has been filed, so it is patent pending. The code stays open under Apache-2.0.
Crimp is open source because a decision gate you can’t inspect is just another black box.
