- [Sprowt Harness now has a native Mac app](https://minimumeffort.dev/blog/sprowt-harness-native-mac-app.md): I added a native SwiftUI app to Sprowt Harness. I can follow a change from its plan to its pull request in a Mac window, with the same Rust engine and saved work as the terminal interface. Published 14 October 2026.

- [Recording the starting point in Sprowt Harness](https://minimumeffort.dev/blog/sprowt-harness-evidence-and-repairs.md): Before a worker edits anything, Sprowt Harness can now prepare its environment, check that the required tools work and record the baseline results against the starting source. Those results stay attached to the attempt, including failures. Published 11 October 2026.

- [Codex and Muse can now work together in Sprowt Harness](https://minimumeffort.dev/blog/sprowt-harness-workers-and-review.md): Codex and Muse can now share a codemod, exchange questions and return failed checks to their owners. A fresh reviewer can inspect the combined result and request scoped fixes. Published 8 October 2026.

- [Getting parallel work back together in Sprowt Harness](https://minimumeffort.dev/blog/sprowt-harness-parallel-work.md): Two Codex workers can now work on the same change, with separate task worktrees and checks against the combined result. Ongoing codemods can also catch up when another PR merges. Published 5 October 2026.

- [Sprowt Harness can now keep working on a pull request](https://minimumeffort.dev/blog/sprowt-harness-can-now-keep-working-on-a-pull-request.md): Continue editing the same pull request, or save a checkpoint and reopen the work later. Published 1 October 2026.
