Steer focus: Seam Discovery & Enforcement

Seam discovery analyzes scenario flows to map variation points where external services and I/O intersect core logic. Documenting these boundaries allows teams to isolate side effects behind adapters, ensuring tests can exercise core logic without triggering expensive integrations.

Side effects leak into core logic when seam boundaries are weak, allowing environment-dependent behavior and I/O operations to entangle with core processes. Hardening these boundaries isolates integrations behind adapters, preventing accidental regressions during scenario execution.

Isolate external services by reinforcing seam boundaries and grouping I/O operations behind focused adapters. This boundary hardening allows tests to substitute dependencies and control integrations, exercising core logic without triggering expensive environment-dependent side effects.

Yes, seam analysis specifically scopes architecture-focused scenario flows involving prompt-managers, external services, and I/O. It reinforces boundaries within these environments, ensuring tests can exercise variation points without triggering heavy side effects or environment-dependent failures.

Document discovered seams by updating a shared seams doc via knowledge-observatory-tools. This knowledge sharing approach records how variation points should behave, cataloging strong and weak boundaries to inform architecture decisions and prevent accidental regressions.

Avoid seam discovery when scenario flows lack external services, I/O, or environment-dependent behavior. If core logic operates independently without integration points, reinforcing boundaries yields minimal testing enablement and modularity improvements for your architecture.
