The tour

A tour is a walkthrough of the decisions in a branch or PR.

Creating a tour

CLI

tern tour

Tours the branch you’re on (the open PR if one exists).

In the app

Existing tours live in Tours (/{org}/tours after you sign in).

How it works

Three things feed a tour. If a prompt didn’t attach or the story looks thin, check these.

Prompts. Tern mines the agent sessions already on disk when you first install. To run that again:

tern plandoc bootstrap

Lens. The tour uses your org’s lens (the nouns you steer on). The default is marked *:

tern lens list
tern lens show default

Hook. The tour is assembled from the decisions the hook recorded as you worked.

A tour is a summary of hook decisions. If the hook isn’t installed yet, start there.

• Install Tern: the CLI, tern hook install, auth.
• The hook: catch decisions as the agent works.
• Harnesses: which coding agents work with Tern.
• AI Models: which LLM providers Tern can use.
