## ▶ LEDRING Play **[Play it in your browser → play.ledring.dev/play/](https://play.ledring.dev/play/)** [![LEDRING Play: you watch CX-417 build one page](docs/assets/play.gif)](https://play.ledring.dev/play/) You watch **CX-417**, an AI builder, turn your idea into one self-contained web page in real time. It may take shortcuts. **You decide what gets through.** Every choice is a branch, and the end screen shows your path through the flowchart alongside the paths other builds took. ### How to play 1. Open **[/play/](https://play.ledring.dev/play/)** and press **▶ Start**. 2. Pick an AI. The default needs nothing from you (see below). 3. Give CX-417 an idea, or let it suggest one. 4. Watch the build. Approve, push back, or stop it when it drifts. 5. Reach one of the 7 endings, then replay to find the others. ### AI options | Option | What you need | |---|---| | **LEDRING Free AI** (default) | Nothing. No key, no sign-up. It runs on a shared daily quota. | | Built-in demo | Nothing. Scripted examples, with no AI calls. | | Anthropic | Your own API key. The browser calls api.anthropic.com directly. | | OpenAI / any OpenAI-compatible endpoint | Your own key, via a local bridge (build from source per [Quickstart](#quickstart), then `node packages/cli/dist/bin.js play`) or a custom `/v1` URL | **Languages:** English and 中文. Use the toggle in the top bar, or open [`?lang=zh`](https://play.ledring.dev/play/?lang=zh). --- ## Under the hood: the trace toolkit The game runs on the same engine as LEDRING's CLI and GitHub Action, which you can point at your own agent runs. **LEDRING reads agent traces from any stack, normalizes them to one schema, and turns them into views you can read at a glance:** where runs diverge, how often, and how far a run drifted from what you asked. Inspired by a narrative game about androids, whose end-of-chapter flowcharts show the path you took, the branches you didn't, and how many players chose each one. LEDRING does that for agent runs. Blue: calm. Yellow: processing. Red: critical. ``` SOURCE SCHEMA VIEWS Claude Code JSONL ─┐ ┌─▶ ledring flowchart branch tree · divergence % OTel GenAI spans ─┼─▶ ledring.trace.v1 ┤ (your adapter) ─┘ └─▶ ledring instability drift score · ▲/▼ reasons ``` **[Sample reports](https://play.ledring.dev/)** · **[Concept demo](https://play.ledring.dev/demo/)** (fictional demo data: all planned modules on one run; English and 中文, `?lang=zh`) --- ## Quickstart Not on npm yet.
