Systems and artifacts
Projects
Three independent projects explore the same question: what must an AI-generated result preserve so someone can inspect it, change it and continue the work?
Relay
Routines → Skills, jobs and retained work.
Relay turns a useful procedure into work an agent can execute and continue. A Skill holds reusable instructions. A job retains the selected files, artifacts, evidence, assigned checks and exceptions.
The public Skills are portable. Relay adds coordination and continuation around them.
Spellshape / Live OBJ
Intent → portable, editable geometry.
Spellshape is an AI-native authoring environment built around Live OBJ. The artifact combines standard OBJ geometry with #@ metadata describing semantic parts, parameters and procedural intent. Ordinary OBJ readers can use the geometry; tools that understand the metadata can continue editing the scene.
The mesh cache travels with the structure that explains how it can change. Metadata-driven editability depends on the capabilities of the consuming tool.
Drawing Analysis Engine
Drawing evidence → inspectable analysis.
A callable PDF drawing-understanding engine. Drawing evidence, declared schedule values, calculated results and engineer approval remain separate. A saved project preserves the source PDF, marked audit PDF, SQLite state and a hashed results index. Unresolved geometry and unsupported exports retain explicit reasons.
The analysis stays tied to its evidence. Running the engine or exporting geometry does not grant engineer approval.
How they can work together
A Skill can expose a callable engine or script to an agent. That creates a way to combine drawing analysis, editable 3D, reports and downstream jobs while each project keeps its own scope.
These are integration directions to test. This page does not claim that Relay already ships an end-to-end drawing or Live OBJ workflow.
