## What it is

promptfoo is an Agent SDK or runtime for tool calls, state, handoffs, tracing, and evaluation boundaries.

## Capability boundary

Agent runtime preflights, tool permissions, state/handoff boundaries, trace acceptance, and evaluation checks

## First safe verification

Verify one minimal agent loop with fake tools and temporary credentials first.

## Main risk

Upgrade or migration may change expected behavior: 0.121.8
