Stability & Versioning
Integrations
LangGraph (anchor integration)
PIC can be enforced at the tool boundary using a LangGraph-compatible tool execution node.
This repo provides:
Expected output:
Your agent must attach a PIC proposal under a reserved argument key:
Tool binding is enforced: proposal.action.tool must match the actual tool name (payments_send).
1. The Core Thesis: Closing the "Causal Gap"
Traditional AI safety focuses on Dialogue Guardrails. However, enterprise agents operate via Side Effects (API calls, financial transfers).
The Causal Gap occurs when an agent performs a high-impact action based on instructions from an untrusted source (e.g., Indirect Prompt Injection). PIC bridges this gap by enforcing a machine-verifiable contract between Input Provenance and Action Impact.
