Engineering notes
How we build Pragma: the principles behind its agents and checks.
- Validation that doesn't flatter: costs, out-of-sample and walk-forward
Why most backtests overstate results, and how Pragma's checks are built to reject ideas that only look good.
- Why our research agents talk through a single API contract
Decoupled stages, outputs you can inspect, and the upfront design cost we accept in exchange.
- Bounded autonomy: loop and budget limits for AI agents
Why autonomous loops drift, and why our agents stop at hard limits instead of retrying forever.
