Current Projects
Port
Install agent infra on your own Cloudflare account. Preview it, keep it, or tear it down.
coil
Agent threads with their own computer in the cloud: terminals, a real Chrome window, and a disk you share.
Marionette
Hard ideas you can poke: hand-wired circuits, replayable bit for bit.
Amber
Pause code your agent wrote: freeze a script mid-loop in a Durable Object and resume it later.
Gleam Agents
Run many coding agents at once, each with its own goal and file scope, graded by hidden tests.
Hand
Computer use without pixel guessing: code lists what can be clicked, Clef picks, the run is checked.
Porch
Your cmux sidebar on your phone.
Accrete
Your coding agents build each npm tool once, then run it with no container.

Operator Profile
Put this at the start of a session so an agent works the way I do. It holds only things that stay true for months: how I think, how to talk to me, my stack, my rules, and where to look things up. It does not list current projects. Look those up live. Goes with Repo Shape, Build Backwards and Sign in with Cloudflare Funnel. Jordan Coeyman. Agent Experience at Cloudflare.

Build Backwards
Put this at the start of a session when the agent needs to know how the work gets built, not only what to build. It describes a process that fights an agent's default habits. Models are trained to build forwards: plan, then execute in one linear pass, like a person writing code from start to finish. Build backwards instead. Start from a North Star, walk back through loop checkpoints, and treat whatever the loop produ

Repo Shape
Put this at the start of a session so new or continuing work matches this shape. The unit is not the repo. The unit is the experiment, and the notebook of experiments is what compounds. A repo is what you extract from a notebook once the receipts have earned it. Work backwards. Aim at something audacious enough to be wrong, then work back to the smallest experiment that produces an artifact either way. A verified-dis

Sign in with Cloudflare Funnel
Put this at the start of a session when you build a public app that people sign in to with their own Cloudflare account. Everything that costs money per person is billed to that person, not to you. The host pays a small fixed floor and nothing that grows with users, idle time, or loops. Reference app: coil. Stack: foldkit + Tailwind client, one Worker, Durable Objects. This goes with Repo Shape. A public app should c
