Changelog

August 2026.

Coshell is a multiplayer AI coding agent. Your team shares cloud dev machines, called drives, and works with the agent in one live session. This is the complete record of what we shipped since the fork from opencode. We update this page with every release.

Meet @coshell, the assistant in every session chat

Mention @coshell in any session chat and it answers about the session, the transcript, and the code in the workspace. Ask it to act and it can send a prompt to the working agent on your behalf, or create, rename, and archive sessions. It keeps listening for a few minutes after you talk to it and judges each message, so a conversation does not need a mention on every line. Drive admins pick the model it runs on from Manage Drive.

New

Ask @coshell what the team is working on

The assistant can see recent sessions across every drive you have access to, and who is online right now. Ask what the team is up to and it answers from live activity, scoped to what you can already see.

New

Typing indicators in session chat

See when teammates are typing in a session chat room. The assistant shows one too while it works on a reply.

New

Verified steps and plan approval

A plan step can carry a verify command. Run it from the step and the result is shared with the whole team, so a checked box is backed by a passing check instead of a claim. Plans can now be approved the same way specs are, and paired documents show one pipeline from draft to done with a single switch between spec and plan.

New

Specs join the Plan tab

The Plan tab now recognizes design and spec documents alongside plans. Specs show their status, can be approved in place, and a single click asks the agent to write the implementation plan from the spec. Plans link back to their spec, and every document a plan references is one click away.

Improved

Accurate stats for self-hosted drives

Manage Drive now shows size, compute, and disk for self-hosted drives, and warns when a machine has less than the recommended resources.

Improved

Sharper plan progress

The Plan tab tracks progress from the agent's own activity on that plan. It updates the moment the agent reads or edits the plan.

Improved

Cloud-deployed drives update themselves

Drives deployed from a cloud template now receive runtime updates automatically. You do not need to redeploy.

Improved

Smarter tab switching

Tab navigation now follows most-recently-used order. The Plan tab remembers which plan you had open.
