StatsClaw is built around one core idea: do not let a single agent own both implementation and validation. Instead, split work into constrained roles with explicit boundaries.
Four-Agent Layout
A minimal setup uses four roles:
- Planner: defines method requirements, acceptance criteria, and artifacts.
- Builder: writes implementation code from planner specs.
- Simulator: creates synthetic data generators and expected behavior scenarios.
- Tester: writes tests and checks criteria without reading planner secrets beyond approved interfaces.
The role split is less about hierarchy and more about epistemic separation.
What Each Role Must Not See
Barrier design matters more than role names. A useful policy is:
- Builder should not see simulator ground-truth parameters.
- Simulator should not inspect implementation internals.
- Tester should not derive expected outputs from builder code.
These restrictions prevent convenient but invalid validation shortcuts.
Artifact Handoffs
A clean handoff sequence keeps the process auditable:
- Planner publishes interface contract and metric definitions.
- Builder publishes implementation and changelog notes.
- Simulator publishes scenario matrix and reference outputs.
- Tester publishes deterministic test outcomes and gate decision.
Each artifact should be reviewable on its own.
Practical Benefits
This architecture improves development in three ways:
- Bugs are more likely to surface before release.
- Teams can localize failures to specific stages.
- Methodological accountability is clearer.
Even small teams can adopt this pattern with lightweight templates and checklists.
Key Takeaway
Information barriers are not overhead. They are the mechanism that keeps validation independent and trustworthy.
