Source control

T3 Code integrates with GitHub, GitLab, Forgejo, Gitea, Bitbucket, Azure DevOps, and GitCafe to clone and publish repositories, create pull requests, and review changes.

Review turn changes

A turn's changed files and diff show only the turn's own work. When a turn pulls, merges, or rebases, the files Git brought in are left out. A file stays in the list when the turn edited it, committed it, or fixed a conflict in it. Use the branch comparison to review everything that changed against your base branch. Restore still returns the complete saved workspace.

Connect an account

Install Git and configure authentication on the machine running your T3 Code server. For a remote environment, do this on the remote machine. After signing in, open Settings → Source Control and choose Rescan.

GitHub

T3 Code talks to GitHub's API directly and only needs a token. Any of these works, in this order of precedence:

  1. A token saved in Settings → Source Control → GitHub. It is kept in the server's secret store, and works without the GitHub CLI.
  2. GH_TOKEN (GH_ENTERPRISE_TOKEN with GH_HOST for GitHub Enterprise Server) in the server's environment.
  3. GitHub CLI 2.81.0 or newer, signed in with gh auth login.

If gh is signed in to several accounts or hosts, expand GitHub in the same place to pick the account each host uses or turn a host off. A saved token or GH_TOKEN takes precedence over that choice; a host turned off stays off either way.

For GitHub Enterprise, sign in with gh auth login --hostname YOUR_HOST. T3 Code treats a custom server name as GitHub once it has a credential for that host.

Forgejo and Gitea

Install Forgejo CLI (fj) or Gitea CLI (tea) 0.16 or later on your T3 Code server. Sign in with fj --host https://your-server auth add-token or tea login add. Repeat for each server you use, including Codeberg.

T3 Code prefers a matching fj login and falls back to tea when fj is unavailable or has no login for that server. Once an account is selected, failed actions stay on that account. Settings shows the detected CLI. The upstream Forgejo integration supports both server types; RTVision also exposes its Gitea review integration for the configured tea server. Servers hosted under a URL subpath, such as https://example.com/forgejo, use tea because fj 0.6 does not preserve the subpath when checking its account.

When cloning or publishing, use a full repository URL to select a specific server. You can use owner/repo when only one fj server is configured, or with your default tea login when fj is unavailable or unconfigured. With multiple fj servers, use the full URL. If you have multiple tea accounts on one server, select one with tea login default <login-name>. Git push and clone also need Git credentials or an SSH key for that server.

GitLab

Install GitLab CLI, then sign in:

glab auth login

Bitbucket

Open Settings → Source Control, expand Bitbucket, and enter one of:

  • Access token: a token created for one repository, project, or workspace. It can only reach what it was created for.
  • Atlassian account email and API token: an Atlassian API token for your account. It can reach every repository you can. Give it read/write access to repositories and pull requests, plus user read access (read:user:bitbucket).

A field saves when you leave it, and applies right away. The access token wins when both are saved. Credentials are saved on the environment's server, so select a remote environment to configure it. Saved tokens can't be viewed again; enter a new one to replace it, or choose Remove to clear everything saved for Bitbucket.

If no credentials are saved, T3 Code falls back to these variables in the server's environment. Restart the server after changing them:

export T3CODE_BITBUCKET_ACCESS_TOKEN="your-access-token"
# or
export T3CODE_BITBUCKET_EMAIL="you@example.com"
export T3CODE_BITBUCKET_API_TOKEN="your-token"

RTVision Gitea review features

Install tea 0.16 or later on the machine running T3 Code. Run tea login add as the same OS user that runs the T3 daemon, enter your Gitea web address and personal access token, then select that login with tea login default <login-name>. The daemon must find this version of tea on its PATH and use the same home/config directory where the login was saved. Tea stores personal access tokens in its local config file.

Existing installations can reuse their T3CODE_GITEA_TOKEN when creating the tea login. T3 no longer reads that environment variable; tea stores and supplies the credentials. The token needs user read access for account discovery, repository access for pull requests, and issue access for comments and labels. Grant write access to repositories and issues for review and lifecycle actions.

Optionally keep the Gitea web root in the daemon environment to select a server explicitly. It must match the tea login URL, including any reverse proxy subpath:

export T3CODE_GITEA_BASE_URL="https://gitea.example.com"

Without an explicit web root, T3 uses the default tea login, or the only saved login. Restart the server after changing its configuration, then choose Settings → Source Control → Rescan.

RTVision's additional review features use one Gitea server per T3 environment. HTTPS remotes must use that web root. SSH remotes can use the same hostname, tea's saved SSH hostname, or an explicitly configured alias:

export T3CODE_GITEA_SSH_HOSTS="git.example.com,work-forge"

Use SSH aliases as git@work-forge:owner/repository.git or ssh://git@work-forge/owner/repository.git. Git authentication remains separate: SSH remotes need the daemon's SSH key or agent; HTTPS remotes need a Git credential helper. Tea can register its helper with tea login helper setup.

Gitea drafts use a title prefix. If your server uses custom work-in-progress prefixes, configure T3CODE_GITEA_DRAFT_PREFIXES with the same comma-separated values and restart T3. T3 verifies that draft/ready changes take effect. Auto-merge uses Gitea's own scheduler and can merge immediately when the request already satisfies its requirements.

Azure DevOps

Install Azure CLI, add the DevOps extension, and sign in:

az extension add --name azure-devops
az login

GitCafe

Install the GitCafe CLI and sign in:

bun install -g @gitcafe/cli
cafe auth login --host https://git.cafe/api

Alternatively, open Settings → Source Control, expand GitCafe, and enter a token. It is kept in the server's secret store, applies right away, and is used before CAFE_TOKEN and the cafe login. Or set CAFE_TOKEN in the server's environment and restart it. Both tokens are only sent to git.cafe; CAFE_TOKEN follows CAFE_HOST if you set it. Repositories on staging.git.cafe need their own login with --host https://staging.git.cafe/api.

Line comments, reviewer requests, and labels are not available for GitCafe pull requests yet. Merging a stack lands it through GitCafe, and updating a branch restacks the layers above it.

Start, clone, or publish a project

To start from nothing, choose New project in the command palette (Cmd/Ctrl+K), or New project under Add Project on any client, and type a name. T3 Code makes a Git repository in ~/.t3/projects (the projects folder of your T3 data directory) with a README, an icon, and a first commit, then opens a new thread in it. Until the project has a thread, new threads work in its folder, even when your default is a new worktree. The folder is named after the project, like pinball-stats for "Pinball Stats". Turn on Create private repository on GitHub to also publish it. If Git has no name or email on that machine, the project is created without the first commit.

Use Add Project in the command palette (Cmd/Ctrl+K) to clone a repository. Choose a hosting provider or paste a Git URL, then choose where to save it. The project opens right away while the clone runs in the background: you can write your first prompt, and sending waits until the files are in place. A toast tracks progress and lets you cancel; if the clone fails, retry it from the toast or from the banner above the composer.

For a local Git repository without a remote, Publish Repository creates a hosted repository, adds it as origin, and pushes your commits. If there are no commits yet, it creates the remote; make your first commit before pushing.

Create a pull request

Use a thread's Git actions to commit, push, and create a pull request. T3 Code can generate commit messages, review titles, and descriptions from your changes.

An existing fork PR can appear beside the branch even if you pushed without setting an upstream. If its badge is missing because several remotes hold that branch, set the branch's upstream to the intended remote with git branch --set-upstream-to=<remote>/<branch>.

Choose the writing style and model in Settings → Source Control. Repository conventions uses the project's instructions and recent commit subjects.

Review and merge

Open Pull requests to review changes and comments, request reviewers, check out a branch, or merge. You can edit review titles and descriptions and your own comments where the host allows it. GitLab calls these merge requests.

Type @ in a review comment or reply to suggest people from the pull request and repository on GitHub, Gitea, and GitLab. Select a name with the arrow keys and Enter or Tab. The mention is sent when you submit the comment or review.

Use Whitespace in the Code tab to hide indentation or spacing changes while reviewing a pull request or a single commit. Choose Show all changes to restore them. Comparisons with separate hunks may need to load both file revisions from the host.

When the host can confirm that one pull request targets another pull request's branch, its review panel shows the dependency chain. Select a related pull request there to open its usual review panel. T3 marks incomplete discovery instead of guessing whether a release branch or another unrelated non-default branch is part of a stack.

On mobile, Pull requests lists reviews across your connected environments. Open a review to read its description, activity, commits, and changed files. Line comments stay as drafts until you submit the review. Work on PR opens a chat with the review attached; sending the first message prepares a worktree from the review's branch.

Previously loaded lists, review details, guides, and diff pages remain readable on mobile without a connection, including after restarting the app. Saved content refreshes when the environment reconnects; submitting changes requires a connection.

Enable Remove agent credits when merging in Settings → Source Control to remove recognized agent co-author and generated-by lines from GitHub merge and squash commit messages. Human co-authors stay credited. The setting is off by default and projects can override it. It also applies to auto-merge, but not merge queues or native stack merges. Original commits keep their messages, so merge and rebase can still retain agent credits in those commits.

On web and desktop, hold Shift in the GitHub pull request list for quick actions. To close several, press Close, drag across the rows in the same group, and release. Press Escape before releasing to cancel. Failed closes stay in the list so you can retry them.

GitHub, GitLab, and Azure DevOps support auto-merge while checks are outstanding. GitHub also supports approving waiting fork workflows and opening a revert pull request for a merged change.

GitHub sharing is off by default. In Settings → Connections → GitHub sharing (Environments on mobile), choose Read PRs or Read and act for each environment you trust to share GitHub access. Enable both the original environment and the environment answering its requests on this client. Read and act can use broader GitHub permissions than the original environment's credential; only enable it for environments you control and trust. Changing a saved endpoint or removing an environment clears its permission.

GitHub review details, linked PR status, and permitted review actions can then use another connected environment signed in to the same GitHub account. Each needs a project on that host. A connected local environment is preferred for actions and can answer slow or failed reads. Browsers and mobile clients need a paired environment to use its GitHub credentials. Credentials stay on their machines. Previously verified credentials remain usable for routing for ten minutes during a GitHub outage; new credentials must be verified first. An action with an uncertain result is never automatically retried elsewhere. Listings, diffs, and checkout or PR creation from Git actions continue to use the project's environment.

For Azure DevOps, use the host website to change comments. Bitbucket does not support reopening a declined pull request.

Review guides

Review guides are in beta. Turn on Review guides in Settings → Source Control to add the Guide tab to pull requests on that server. On mobile, move between stops with Next and the back button; a stale guide offers a rewrite and hides excerpts that no longer match the current change.

The Guide tab gives you a tour of a pull request without reading it line by line: stops through the change in reading order. Each stop points at the lines worth reading, and a stop marked Look closely has a call only a maintainer can make. Mechanical changes such as renames and snapshots are grouped at the end, and every changed file appears somewhere on the tour. Conversations already resolved in review are left out. For a pull request in a stack, the guide covers that layer only, and may point out what a lower layer introduced or what a higher one uses.

Choose Write guide to have the review guide model from Settings → Source Control read the change in a temporary checkout; without one set, the source control writer model is used. Nothing in the checkout is changed, and a large pull request takes a few minutes; you can go elsewhere in the app. On web, you are told when the guide is ready; on mobile, return to the guide to check its progress. Claude and Codex can write guides. The guide is kept for everyone using this server. To write it again, for example after a push or after changing the model or instructions, choose Rewrite guide from the pull request's ⋯ menu.

On web, while reading a stop, select lines in an excerpt to add a comment to your review or ask an agent about them; comments wait with the ones from the Code tab until you send the review. Choose a suggested question, or Ask about this stop, to open a thread that already knows which stop you are on. Finish review on the last stop opens the review with everything you collected.

Agents can write guides too: ask one to prepare guides for a set of pull requests, and it starts them for you. Each is read through the project whose checkout has that repository.

To shape guides to your taste, write Review guide instructions in Settings → Source Control, such as what to show first or what to skip; projects can override them. They change emphasis and ordering, not the guide's layout or which files it covers.

Mark files as viewed

Tick a file off in the Code tab once you have read it and it collapses; the toolbar keeps a running count. A tick belongs to the pull request rather than to a commit, so scoping the tab to a single commit keeps them. Uncheck a file to review it again. Where revision tracking is available, a file pushed to after you cleared it comes back marked Changed.

On GitHub and Gitea servers that support viewed-file access, these are the host's own marks, so progress carries between T3 Code and the host's website in either direction. Other Gitea servers, Forgejo, GitLab, Bitbucket, and Azure DevOps expose no record T3 Code can read, so the server you are connected to keeps them instead: they follow you across the apps connected to that server, but the host's own site will not show them, and the count reads viewed in T3 Code.

On mobile, open a changed file and mark it viewed from its header. Viewed files collapse, and their marks follow the same rules as on web and desktop.

Gitea supports PR tracking, comments, reviews, diffs, reviewer and label updates, merge methods, branch updates, close/reopen, draft/ready changes, auto-merge controls, comment editing, and reactions. Workflow approval and revert PRs are available when your Gitea server advertises support for them.

In a pull request's checks, expand CI runs to see GitHub Actions or Gitea Actions runs and jobs for the current revision. You can open their details or rerun a completed run, its failed jobs, or a selected job when your account has write access. A job rerun may also run dependent jobs. Use Refresh CI to see subsequent progress. On mobile, open the thread's Git sheet and expand CI runs and checks.

Troubleshooting

  • Not authenticated: run the provider's login command on the server, then rescan. For Bitbucket, check the credentials saved in Settings → Source Control, or confirm the running server received the environment variables. For Gitea, confirm the running server received the environment variables.
  • GitHub sign-in cannot be verified: update GitHub CLI to at least 2.81.0, or save a token in Settings → Source Control.
  • Push fails despite a connected account: check the Git remote's credentials. SSH and HTTPS remotes can require separate setup from the hosting provider's API access.
  • A review cannot load: open it on the host website while resolving connectivity, permissions, or rate limits.

Linked pull requests

A thread can hold several pull requests, including reviews from another repository on the same host. Use Link pull request in the command palette or Linked pull requests panel, or right-click a pull request link in the conversation. Creating a pull request from Git actions links it automatically. Agents can link their pull requests with the link_pull_request tool.

Use Link this PR in a branch-detected badge's tooltip to keep it with the thread. From a review on the Pull Requests page, Link to thread lets you search for an active thread. The review header also lists the threads that link to it, including archived threads, so you can return to their context.

Thread badges show a stack's layer count or the current review number with a count of additional links. Clicking a badge with more than one review opens the Linked pull requests panel. On mobile, the Git overview lists linked reviews and their stacks; tap a review to open it. Linking and unlinking are available in the web and desktop clients.

The Linked pull requests panel lists every review and groups stacks. Unlink a review from its row menu. An unlinked stack layer stays out of later syncs. Open linked reviews refresh on the server; closed reviews refresh periodically so reopening one on the host is detected. Merged reviews refresh when requested. A settled thread's reviews stop refreshing until you unsettle it. With Auto-settle merged threads enabled, a thread can settle after every linked review is terminal. An open or unsynced link keeps it active.

Ask the agent to watch, monitor, or babysit a pull request and it calls watch_pull_request. While the thread is active, the server checks the pull request every two minutes and wakes the agent when a check fails, the required checks pass, someone else comments or reviews, or the branch starts to conflict. Threads in a project that watch the same pull request share one check. On GitHub, a check first asks whether anything changed and reads the pull request only when it did, which keeps watching inside GitHub's rate limit. Comments from your own account do not wake it. Watching ends when the pull request merges or closes, after 10 wakes in a row that bring only comments, after 8 failed reads in a row, or when you press Stop on the thread. A rate limit only pauses watching. Settling or archiving a thread also ends all its watches. Unsettle the thread before starting a new watch. Watching a pull request again does not repeat check or conflict news its last watch already reported; unlinking the pull request clears that. Subagents cannot watch pull requests; the thread that delegated to them does. To start or stop it yourself, use the row menu in the Linked pull requests panel. In the thread details card, a watched pull request shows an eye; click it to stop watching.

A watched thread counts as working between wakes, so it stays in the Working section and does not auto-settle. Agents stop watching when they hand the work back to you, and the thread then returns to your inbox.

Cross-repository links use a project on the same host. Azure DevOps reviews require a project checked out from the matching organization and repository.

GitHub stacks

The Pull Requests page shows each PR's position in its GitHub stack. Open the stack badge in a review to navigate its layers. Merge stack submits the selected pull request and every unmerged layer below it to GitHub together, respecting branch rules and merge queues. The confirmation shows the scope and merge strategy. GitHub rebases the remaining stack after merging.

Rebase stack updates remote branches from bottom to top without changing your local checkout. It can rewrite history and restart checks. If a layer fails, earlier updates remain; resolve that layer before retrying. GitHub may require manual conflict resolution after a lower layer is amended, even when its changes look independent. Stack actions require an environment that supports them.
