I have a Symphony-style[1] factory, which keeps all the context in a single session, but I want to start splitting into stations with separate sessions, and I hadn’t worked out how to do communication between sessions.

JSON Canvas nails the simplicity-it's easy to read and easy to implement. We wanted to build on that spirit while tackling some of the challenges showing up in this thread: nested canvases, extensibility for custom app data, text styling, coordinate systems, and round-tripping between different canvas apps without data loss.

OCIF v0.7.0 just came out. It's designed to be an interchange format — so different canvas tools (Excalidraw, TLDraw, Obsidian, etc.) can export/import each other's canvases.

Some highlights:

- Extensible: apps can attach their own data via extensions, so nothing gets lost even if the features aren't supported

- Nested canvases via parent-child node relationships

- Local coordinate systems (addresses the pixel positioning concerns raised in another comment here)

- Text styling, viewport control, and more via built-in extensions

If JSON Canvas isn't quite meeting your needs, OCIF[1] might be worth a look.

Aside: it also helps for code review! Review bots can point out the diff between plan and implementation.

Some examples for the curious: https://github.com/sociotechnica-org/symphony-ts/tree/main/d...

I spend $140/mo on Anthropic + OpenAI subs and I use all my tokens all the time.

I've started spending about $100/week on API credits, but I'd like to increase that.

Would be happy to swap war stories.

I would expect cost to come down over time, using approaches pioneered in the field of manufacturing.

For those of us working on building factories, this is pretty obvious because once you immediately need shared context across agents / sessions and an improved ID + permissions system to keep track of who is doing what.

To name one probable area of involvement: how do you specify what needs to be built?

Works great. Amazing how durable the faucet is!

There’s a way of knowing something that can be recalled orally from memory that is different and valuable. But we even measure it using a yardstick for written knowledge (accuracy, breadth, etc).

I believe this overemphasis on written knowledge (really, it’s implicitly a denial that any other type exists) is part of what drives the hysteria about LLMs ending the world. LLM doomerism has to believe that written knowledge is at least the most important if not the only necessary form of knowledge.

I’ve started using conductor.build and it feels nice, but would happily evaluate others.

Prompts + tools matter.
