factory SKILL.md skillA
factory from echohack/factory is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add echohack/factory/factory@git:20261022.08db81fPins git:20261022.08db81f in mdr.lock. Pin the fingerprint instead.

Build interactive visualizations of programs, algorithms, and software systems using Factorio objects and locally imported game artwork. Use when the user asks for a Factorio-style explainer or invokes /factory; map execution state to belts, inserters, machines, items, buffers, and circuits.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Factory Explain a program as a working factory. Moving items are values, machine cycles are operations, and accumulating stock is program state. The mechanism should make the program understandable before the reader studies its labels. Requires Node.js 20.10+, a browser, and Factorio artwork imported from the user's own copy of Factorio 2.0 with Space Age. The repository ships the library's manifest and catalog but no game art. If `assets/` holds no PNG files, stop and ask the user to import it as the README's Game assets section describes. Never download Factorio art from anywhere else. The repository follows Anatomy’s useful separation: instructions here, reusable code in `kit/`, the object library in `catalog/`, factory patterns in `patterns/`, complete examples in `examples/`, focused guidance in `references/`, and deterministic preparation/checking tools in `scripts/`. ## Start from the program Read the relevant code or algorithm. Identify its input, transformations, branches, stored state, and observable result. Choose a small example that exercises the interesting behavior. Do not imply that visual concurrency or physical distances …

How to install
mdr add echohack/factory/factory@sha256:0561eb47dcecd754The line at the top of this page pins the label git:20261022.08db81f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
