Demo providers and configuration
This page describes how the Graph Editor chooses providers and harnesses, what is selectable today, and how settings persist. Behavior matches the demo app — not aspirational UI.Provider vs harness
They are independent in the runtime. The demo UI may set both from one first-run choice via
resolveDemoSession.
Selectable providers (first-run)
Continue is enabled only when requirements are met (Chrome supported for Chrome AI; bridge + model for Ollama).
Chrome AI
Use when you want a zero-setup path in Chrome. The demo invokes@executioncontrolprotocol/chrome-ai for availability checks and generation. If the on-device model is not ready, follow the in-app install UI.
Ollama
Use when you want stronger local coding models and Fluent/TS workflows. Prefer:?token= and ?bridge=. The Ollama option enables when GET /health reports ollamaReachable. Choose an installed model in Ollama settings before continuing.
Manual pairing is possible if you paste a bridge URL and token; ecp up is the supported path.
Cloud providers (bound, not first-run selectable)
The demo type system and dependencies include OpenAI and Claude (openai, claude). They map to @executioncontrolprotocol/openai.generate and @executioncontrolprotocol/claude.generate. They are not offered in the current first-run modal. When enabled in a future UI or custom fork, API keys belong in the encrypted browser-secrets vault — never in workflow manifests.
What the demo environment binds
The app’s environment factory typically binds:- Format extensions: TOON, Mermaid, EQL (and Fluent encode via core)
- Model providers used by the selected mode
- nano and coding harnesses
- Registry / session control (including freeze-on-run policy as configured)
evaluate plus the selected provider generate — not template-only FAQ stand-ins.
Persistence and secrets
Do not put secrets in workflows. Portable workflows use
ref() / state — not raw credentials.
Panels and formats
The Graph Editor exposes panels for:- Fluent / TypeScript source
- Canonical JSON workflow manifest
- TOON
- Mermaid graph view
- Run and validation results
ecp.encode / ecp.decode. See Encode, decode, and patch.
