The reference for an artifact factory.

Esy automates the production of high-quality, reviewable artifacts. The reference covers the API contract, runtime semantics, cost accounting, and the workflow templates running in production today.

Reference atlas

The primitives that make Esy measurable.

Six entries define the surface area. Read these first; everything else is a specialization.

Concepts

Workflow templates

Reusable templates that define intake, runtime steps, providers, quality gates, and budget policy.

Read Concepts

Runs

Durable execution records with per-step telemetry, provider settings, costs, and outcomes.

Read Concepts

Artifacts

Generated outputs — visual, video, research, or knowledge — with full provenance back to their run.

Read Concepts

Costs

Estimated, provider-reported, and reconciled cost states. Every number has a documented source.

Read Reference

API

Runtime endpoints for creating runs, listing persisted outputs, and inspecting telemetry.

Guides

Step-by-step walkthroughs for the workflow templates running in production today.

Operating principles

How Esy thinks about producing output.

Structure over prompting

Work begins with a workflow template — a structured intake designed for a specific artifact class. Not a chat box hoping for the right output.

Artifacts over conversations

Outputs are persisted with provenance, telemetry, and review state. A conversation can be the artifact; ephemeral chat history cannot.

Ready-to-use over requires-editing

Finished work, not rough drafts. Artifacts pass quality gates before they reach review or delivery.
