Your agents work as one.
Shelled gives every agent a role and a shared plan. Describe the outcome once, and the agents plan, build, test and review the work together — landing it as a single pull request.
One prompt · four agents · one pull request
Many agents. One outcome.
Shelled is built around the idea that a coordinated team beats a lone assistant. Each agent owns a role, and the work only ships when it all lines up.
Every agent has a role
Planner scopes the work, Builder writes the code, Tester wires the checks, Reviewer guards the diff. No agent guessing at someone else's job.
One shared plan
The agents work from a single manifest of intent, so parallel work converges instead of drifting into conflicting branches.
Work runs live
Tasks stream in sandboxed shells as the agents run. Watch files land in real time, and step in whenever you want.
Reviewer catches drift
A dedicated review agent re-reads the diff against your intent and flags it before anything reaches you.
Nothing gets lost
Every run is checkpointed. Roll back a single agent's work without discarding the rest of the run.
Lands where you work
Opens a real pull request in your repo with tests and a readable diff — no snippets to copy out of a chat box.
From prompt to pull request.
Every run follows the same five steps, so you always know where the agents are and what happens next.
Describe the outcome
State the destination — “add passkey auth” or “migrate the billing API.” One sentence is the whole brief.
Assign the roles
The Planner splits the work into tasks and hands each one to the agent whose role fits it best.
Build in parallel
Agents work in parallel sandboxes while you watch the diff take shape. Step in at any point to change direction.
Verify before it surfaces
Tests, types and the Reviewer's pass all run before anything reaches you, so you never review broken code.
Ship the work
The run lands as one reviewable pull request in your repo — commits, tests and reasoning attached.
A team you can actually steer.
Single-assistant tools give you a very fast intern. Shelled gives you a team with roles, a shared plan, and a reviewer that catches drift before you do.
Planner, Builder, Tester and Reviewer run in parallel — a team, not a queue behind one model.
However many agents run, the work lands as a single reviewable diff against your branch.
Self-host the whole system. Your repositories, keys and model calls never route through our servers.
Free to start. Simple to scale.
Start on open source, upgrade when you want the agents managed for you. No lock-in, ever.
