    thirdshift in 31 seconds

    Give thirdshift a GitHub issue and get back a pull request ready for your review, shown with a real overnight Run in which issue #663 became merged pull request #665.

    Title card: thirdshift in 31 seconds. Issue in. Reviewed pull request out. Beside it, a terminal from an overnight Run on 12 October 2026 takes issue #663 and reports pull request #665 merged.Play

  2. Engineering leaders ·

    thirdshift, briefly

    A two-minute overview of thirdshift as a deterministic program wrapped around AI agent sessions, with a real overnight Run, what happens when a Run fails, and the one limit to know: sessions run as you, not in a sandbox.

    Title card: thirdshift, briefly. For engineering leaders, in two minutes. Beside it, a slide lists what helps get it right: test-first, two independent reviews, reported bugs reproduced then fixed or set aside, and unfixed findings listed in the pull request with a reason.Play

    How thirdshift works

    thirdshift claims the issue, gives the Run its own Git Worktree and starts an agent session that implements the change, gets two independent reviews and opens a pull request, then its deterministic code merges in the Base branch, watches CI and starts a Repair when needed.

    Title card: How thirdshift works. From GitHub issue to reviewed pull request. Beside it, the Delivery loop: merge in the Base branch, push and watch CI, start a Repair session on a conflict or CI failure, and exit with a checked pull request.Play

    How thirdshift works, step by step

    Key terms first: who's involved, the one rule (the agent writes the code and opens the pull request; everything else that touches GitHub is thirdshift's deterministic code), and the six steps of a Run, laid out by who does each one.

    Title card: How thirdshift works, step by step. Who does what in a Run. Beside it, a table of a Run's six steps, split between thirdshift's deterministic code, the AI agent and GitHub.Play

    How to use thirdshift

    Getting started: install, setup, your first Run, watching it, when a Run fails, merging and running on a schedule, where every terminal line shown is real thirdshift output.
