Signal Loom

Observe, evaluate, and ship reliable agent workflows from one Python-native surface.

Northstar Relay Forge VectorLake
Compose

Model agent work as explicit steps

Shape tools, review points, and retry policy without hiding the workflow behind a client-side framework.

Plan -> retrieve -> call tools -> review -> respond
Observe

Trace every run as stateful product UI

Expose timeline, artifacts, source provenance, and recovery actions as first-class screen objects.

Run timeline with source bundle, retry, and reviewer handoff
Improve

Turn production traces into evals

Keep quality loops close to real user behavior and make regression evidence visible.

Trace -> eval case -> reviewer score -> release gate

Proof before integration code

4 golden screens
320px phone proof
0 utility classes added

Build the next mock from a screen, not a blank grid

Start with a catalog archetype, choose a profile, then let primitives and components carry the details.
