Sevenbox Wants to Preserve Why an AI Agent Believed Something

sevenbox.dev Observed source
Editorial interest 78/100 Selection signal · not a rating of the site

Sevenbox proposes a formal calculus and reference runtime for auditing the causal justifications behind AI-agent decisions.

Landing page captured for the 2026-09-08 issue.

Field notes

Sevenbox models each agent decision as a Warrant: a claim tied to the specific prior claims that support it, along with whether acting on it can be undone. The site’s example involves a fraud check arriving after a refund, with the later finding superseding an eligibility claim and triggering a causal search for resulting obligations. It positions the library beneath an existing stack and says it has been tested against 14 agent frameworks, while remaining closed to general access.
