Welcome wizard

T3 Code shows a setup flow when you open a new installation or connect to the hosted app for the first time. Existing workspaces skip this flow.

Choose a connection

• This computer runs agents on the computer that hosts T3 Code. It does not require an account.
• T3 Connect connects computers that are signed in to your account. Run npx t3 connect on each computer you want to add, then start T3 Code or run npx t3 serve so the computer stays available.
• Pair a server connects directly to a server on your network or tailnet. Start the server with npx t3 serve, then run npx t3 pair --tailscale and paste the pairing link. You can also run npx t3 serve --host <address> and use npx t3 pair when the server is already reachable on your network.

If T3 Code cannot confirm the workspace during startup, the setup flow shows Still connecting instead of opening the app. Select Reload to try again.

If T3 Code cannot read your saved settings, it shows Could not read settings. Select Retry after storage becomes available. Setup does not replace unreadable settings with defaults.

Check your agents

T3 Code checks the selected computer for Claude Code and Codex. If an agent is not installed or signed in, select its action to open a terminal with the correct command ready to run. Other providers can be enabled in Settings.

The setup terminal uses the home directory and environment configured for the selected provider instance. Sensitive values remain redacted in Settings and terminal metadata while the terminal process can use them.

Import your projects

T3 Code finds directories that Claude Code or Codex has used. The default selection includes projects active within the last 30 days. Select Choose to include older projects or change the selection.

A large or malformed history can reach the scan limit. T3 Code keeps the projects it found and warns when projects or conversations may be missing.

Imported projects include Codex and Claude conversations active within the last 30 days. You can continue those conversations in T3 Code.

Conversation import is best effort. T3 Code keeps the first user prompt and the newest remaining visible user and assistant messages, with 200 messages total. It omits tool activity and attachments. For Codex, it omits generated setup context only when a canonical user event and a valid shared turn ID identify the same user turn. Ambiguous legacy or response-only context stays in the imported conversation so T3 Code does not remove user text. It reads one conversation at a time and skips files larger than 16 MiB. It ignores malformed records and skips unreadable or unparseable conversations.

Each import attempt reads up to 100 conversation files and 64 MiB per project, with up to 100,000 input records. Run import again to continue a large batch. Completed conversations are not imported again. You can continue without the remaining history.

You can skip agent setup and project import. Select Back to return to a previous step.
