# Start a mission from a Slack thread and get back a verified pull request

> Early access: start a SHIP mission from a Slack thread. SHIP plans, builds, reviews and tests the change before the pull request reaches the thread.

Early access, for engineering teams.

SHIP plans, builds, reviews and tests the change a Slack thread describes. You get a pull request that passed your CI.

- **For:** Engineering teams that discuss bugs and requests in Slack and want a tested pull request back.
- **Instead of:** A bot that opens a draft and leaves every check to you.
- **Runs today:** Linear and GitHub Issues work today. Assign the issue in Linear, or comment @SHIP on a GitHub issue. From a terminal, ship delegate plan builds from a spec you wrote.

## Move a thread to a pull request in three steps

1. **Connect Slack and GitHub.** Authorize your Slack workspace and install the SHIP GitHub App on your repositories. A project pins one Slack channel and one repository.
2. **Describe the work in the thread.** Write what done looks like as a checklist in the thread. The Tester checks the change against it on a preview.
3. **Mention SHIP in the thread.** Tag SHIP in the thread. The plan, the review verdict and the test result come back as replies while the mission runs.

## Get more than a status update in the thread

- **Plan before any code exists.** The Planner reads the thread and the repository and writes a plan. A checkpoint can hold the mission until you approve it.
- **Gate every change on your CI.** A failed check goes back to the Builder with its logs. The pull request reaches you only after your CI passes.
- **Review with a second agent.** A Reviewer that did not write the code reads the diff against the plan. It lists the fixes it requires and the ones it only suggests.
- **Report status back in the thread.** Every stage posts its status as a reply in the same thread, from the plan to the finished pull request.

## Check the loop on 260 missions

In the SWE-in-a-team study, 260 missions went through the loop that early access brings to Slack. The loop sent 46 runs back and corrected 40 of them without a person.

## Compare SHIP with the agents Slack already starts

- **SHIP:** In early access: Takes the thread's request through a Planner, your CI, a Reviewer and a Tester before the pull request reaches you.
- **SHIP:** In early access: Posts the plan, the review verdict and the proof from the test back in the thread.
- **SHIP:** Generally available: Runs each role on the harness and model you choose, on your own provider keys. ([Schema](https://letsship.ai/docs/configuration/schema))
- **Claude Code in Slack:** Starts a cloud coding session when you invite it to a channel and mention it with a task. It posts status in the thread and can open a pull request when the session finishes. ([Claude Code in Slack](https://code.claude.com/docs/en/slack))
- **Claude Tag:** Runs the same assistant for a whole organization on a Team or Enterprise plan. A bug reported in the channel comes back as a draft pull request from an ephemeral sandbox. ([Claude Tag overview](https://claude.com/docs/claude-tag/overview))

## Frequently asked questions

### Is SHIP for Slack available today?

Not yet. Slack is in early access, and SHIP works with Linear and GitHub Issues today. A team can start a mission from a terminal with ship delegate plan and a spec file. [Ways of working](https://letsship.ai/docs/getting-started/ways-of-working)

### When is Claude Code in Slack or Claude Tag the better fit?

They fit a team that wants a bot to post status in a thread and open a draft pull request by hand. SHIP fits a team that wants the plan, CI, review and a preview test done first.

### Which coding agents does SHIP run?

SHIP runs claude-code, codex, pi, kilo-code and open-code. You set the harness and the model for each role in ship.yml, on your own provider keys. [Schema](https://letsship.ai/docs/configuration/schema)

### What happens when I join the early-access list?

You answer four questions about your team and the coding agent you use. SHIP emails you when the Slack integration opens to your team.
