The definition lists the repositories; see [Repositories](/self-hosting/configure). computer reports the pushed branch sp/C08EN6G4T2K-1791312345-821900 and the pull request link ## Session directory Each session has its own directory with one `git worktree` per repository, so it does not see another session's uncommitted work. | Item | Value | | ----------------- | --------------------------------------------------------------------------------------------------------------------------------- | | Session directory | `/people//sessions//`, where `` is the session's owner | | `` | The session key, with each run of non-alphanumeric characters replaced by `-`: thread `C0B:1791.82` becomes `C0B-1791-82` | | Contents | `AGENTS.md` with the workspace's instructions, and one subdirectory per repository. The directory itself is not a git repository. | | Branch | `sp/`, the same name in every repository of the session | | Starts from | `origin/`, fetched at session start. If the fetch fails or takes over 5 seconds, the last fetched commit. | A session starts with the repositories already cloned on the computer. It checks out any other repository listed in its `AGENTS.md` with the `checkout_repo` tool, on the same branch from the latest default branch. The clones behind the worktrees: Git. ## Commits | Field | Value | | --------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- | | Author | The session's owner, by the name and email in the [people list](/self-hosting/configure), even when another person in the thread asked for the change | | Committer | `Computer `, or `SP_COMMITTER_NAME` and `SP_COMMITTER_EMAIL` when set | Claude Code's own attribution lines are turned off for commits and pull requests. ## Push and pull request The session pushes and opens pull requests with `git` and `gh`, following the workspace instructions in `definitions/computer/AGENTS.md`: * Commit on the `sp/` branch, or on a branch with a better name. * Push with `git push -u origin HEAD` and open the pull request with `gh pr create`, one per repository changed. * Do not push to a default branch unless the person asks. * Say in the pull request body who asked: `Requested by @ in Slack`. To change this, edit the [instructions](/self-hosting/configure). ## Identity and tokens `git` and `gh` authenticate as the instance's GitHub App, so the app's bot account pushes and opens the pull request. The person appears as the commit author and in the pull request body. | Item | Value | | --------------------------------- | ----------------------------------------------------------------------------------- | | Reachable repositories | Those granted to the app's installation; see [Connect GitHub](/self-hosting/github) | | `git` token | Limited to the repository in the remote URL | | `gh` token | Covers every repository the installation grants | | Storage | No token is written to disk; the app's private key stays on the gateway. See Git. | | Host not connected to the gateway | The token request fails and `git` fails without prompting | ## `!diff` `!diff` runs in the session directory, which is not a git repository, so it answers `no changes` whatever the worktrees contain. Ask the session for the diff of a repository. ## When a session directory is deleted | What | Deleted after | Condition | | --------------------------------------------------------------------------------------------------------- | ------------------------------------------------ | ------------------------------------------------------------------------------ | | The session directory and its local `sp/` branches | 14 days idle (`SP_FORK_RETENTION_DAYS`) | Every worktree is clean and every commit is on a remote. Otherwise it is kept. | | Git-ignored build and dependency directories (`node_modules`, `.next`, `target` and similar; list in Git) | 24 hours without use (`SP_ARTIFACTS_IDLE_HOURS`) | The session has no running runner. | A message to the thread after its directory is deleted gets a new directory from the default branch. Pushed branches are still on GitHub.
