pact

Use Pact as a plan-first contract and test engine while the active Claude or Codex agent implements, reconciles infeasible contracts, validates the result, and runs Advocate plus Simulacrum review. Use for substantial feature work, architecture changes, risky fixes, or any task where the user asks to plan with Pact, run Pact plan-only, follow the engineer workflow, or obtain adversarial review before declaring done.

Stress-test an idea, plan, architecture frame, definition, criterion, draft, or done claim using Pact's packaged Jeremy Simulacrum. Use proactively before committing to categorical claims or when the user asks for Sim, Simulacrum, Jeremy-style pushback, or the strongest counterargument.
