No, Cookbook is not open source.

A hosted shared task board where humans and coding agents (Claude, Codex and others) claim tasks atomically, return attributed 'receipts' showing cost and files touched, and accumulate a team's decisions into a shared memory that feeds future agent runs. It is a closed SaaS launch aimed at the coordination problem when several people each run agents — the build-vs-buy counterpart to self-hosted options like Buzz — but with undisclosed pricing and vendor-stated mechanics.

## Notes

- What is claimed vs verified: atomic task-claiming (so two agents don't grab the same work), per-task receipts with cost and files touched, and a shared memory that later runs draw on — all stated on the launch page (WebFetch 2026-09-22), none independently tested. The UI surfaces per-run cost figures; there are no published pricing tiers.
- What it is not: no repository, no license, no self-hosting. This is a hosted product, and its facts are vendor claims — treat accordingly.
- The GTM-stack read: the useful signal here is that "coordinate several people's agents" has become its own product category. Cookbook is the buy side; Block's Buzz (Apache-2.0, self-hostable, also in this update) is the build side. If cross-agent task collision and lost decision history are real pains for your team, this is a live option worth a trial — with eyes open that pricing is undisclosed and everything runs on the vendor's infrastructure.
