What’s the scariest tool your agent can call?

For me it s always one of these:

  • Payments / billing (spend real money)

  • Exports / data pulls (leak customer data)

  • Infra / ops (spin up compute, delete, deploy)

PIC Standard adds a machine-verifiable Action Proposal before any high-impact tool call.
Schema + verifier. If trust/evidence is insufficient, it fails closed and blocks the action.

Question: In your stack, what s hardest to make safe?

PIC Standard: AI Action Firewall - Stop prompt injection from triggering tools.

Open protocol that forces AI agents to prove their intent and back every important action with verifiable evidence, before anything dangerous happens. Quick benefits: - Stops prompt-injection disasters and hallucinations from turning into real money losses or data leaks - Works locally: no sending sensitive data to the cloud - Plugs right into LangGraph or your existing agent stack in minutes - MCP ready - Free & open-source (Apache 2.0): audit it, fork it, own it
