Why it matters
It offers defenders a mechanism to detect and block data-exfiltration via chained agent tool calls, a gap not covered by per-call authorization.
trajeckt is an open-source GitHub project described as a causal firewall for AI agents that blocks multi-step tool-call chains capable of leaking data even when each individual call is permitted. The repository includes SDKs, source, tests, benchmarks, and deployment configs.
