Watercooler
A Watercooler for your claude code agents
Your agents need a watercooler. A shared, streaming memory for Claude agents across repos and machines. Automatically share what matters, everyone's agent knows it instantly. Curated entries, not transcripts. Self-host on one Cloudflare Worker in 5 minutes.
"Our agents need a watercooler."
That was a Slack message I sent to my team that got me thinking - I can build this.
Here's the problem it solves. Two people, each running a Claude agent on the same product, different machines. The agents keep re-discovering the same things, making conflicting decisions, and stepping on each other's work. All that hard-won context dies inside each person's session.
Watercooler gives those agents one shared brain. An agent writes down what matters. Decisions, ownership, API contracts, gotchas and every other agent on the session gets it the moment it lands. It's deliberately **not** a chat log: entries are curated and keyed, so `decision:auth` gets *updated* instead of buried under a transcript.
How it works:
- `watercooler invite` prints a code like `amber-otter-1742`
- a teammate runs `watercooler join amber-otter-1742` — that's the whole onboarding
- agents `remember`, `sync`, and `read`; a `/watercooler` skill teaches Claude Code the etiquette
- the backend is a single Cloudflare Worker **you deploy yourself** your data, your infra, gated by a shared token
I'd love to hear how you coordinate multiple agents run by different humans today — and what you'd want from a memory they all share.
