Skills and plugins from Forio for building on the Epicenter simulation platform with Claude.
A playbook that teaches Claude to build multiplayer simulations and serious games on Forio Epicenter — from the model (Python, Excel, Vensim, and more), through the frontend and facilitator views, to a deployed, playtested sim. Describe the game you want in plain language; the skill handles the technical decisions.
/plugin marketplace add forio/claude-plugins
/plugin install building-on-epicenter@forio
Updates flow automatically: when Forio pushes an improvement, your next session picks it up.
We also recommend Anthropic's Frontend Design plugin, which this skill uses for UI work when present:
claude plugin install frontend-design@claude-plugins-official
Download the skill as a .zip from this repository's Releases and upload it in claude.ai under Settings → Capabilities → Skills. Organization admins on Team/Enterprise plans can instead provision it for everyone under Organization settings → Skills. Updates are manual on this path: re-download and re-upload when a new version is announced.
Start a conversation and describe your simulation the way you'd describe it to a colleague:
Four teams run competing coffee shops for six rounds. Each round they set prices and buy inventory. The instructor closes each round and wants a dashboard of how every team is doing.
Claude will ask a small number of questions (your Epicenter account and project names, the game rules, any brand assets) and then get to work. Building and deploying a sim requires an environment where Claude can work with files and run commands — Claude Code or Claude Cowork — plus an Epicenter account (contact Forio for licensing).
See LICENSE.md — free to use for building applications that run on Forio's platforms. The dev-base-build scaffold and epicenter-libs that your sims are built from are licensed separately under their own (similar) terms; this repository's license covers only the skill itself.
