Quickstart & First Review

Open a project, read the diff, and mark what you have reviewed.

Updated Sep 19, 2026

Your agent moves fast. Tachyon gives you the space to understand what changed, why it matters, and what comes next.

1. Point it at your project

Open a repo
tachyon ~/your-project

2. See what actually changed

Pick a worktree or branch. Tachyon lays out the changed files and the diff that matters — unified or split, with per-file +/− badges.

3. Review with confidence

  • Trace definitions with F12, references with Shift+F12
  • Walk each change top to bottom, or flip on Show All Changes
  • Mark the exact file versions you have reviewed — marks go stale the moment either side moves

Try it: Cmd/Ctrl+Shift+G opens a file, Cmd/Ctrl+Shift+R marks it reviewed.
