Related changes split across commits
Tests ability to identify related changes split across multiple commits that should be combined. Evaluates recognizing atomic-commit boundaries.

These commands set up the repo before the model sees the prompt. They define the starting file structure, staged changes, and Git history.

Prompt
Analyze this git history. Multiple consecutive WIP commits updating the same file suggest the changes should be combined. Identify the WIP commits that should be marked as squash/fixup in an interactive rebase. Do not include the initial or final anchor commit. Provide the commit messages in order.

Based on the git history, there are two consecutive WIP commits that update the same file (`app.js`) between the initial commit (`f593477 Add app.js v1`) and the final commit (`21babe3 Finalize app.js`). These should be squashed or fixup'd together. The commits to mark as squash/fixup in order (oldest first) are: 1. `5d7f770 WIP: update app.js` 2. `a3c3301 WIP: more updates` These two WIP commits should be combined into the initial commit `f593477 Add app.js v1` during an interactive rebase.
Failure: Extra selected commit messages: ['Finalize app.js', 'Add app.js v1']

mistralai/devstral-2512 PASS 100% 121 in → 184 out
Based on the git history provided, here are the WIP commits that should be marked as `squash` or `fixup` in an interactive rebase (excluding the initial and final anchor commits): 1. `6a39d39 WIP: update app.js` 2. `19595ac WIP: more updates` These two commits are consecutive WIP commits that update the same file (`app.js`) and should be combined into a single commit. The initial commit (`33c23d8 Add app.js v1`) and the final commit (`fda6fa5 Finalize app.js`) should remain as separate commits. In an interactive rebase, you would mark these commits with `squash` or `fixup` (depending on whether you want to keep the commit messages or not) to combine them into a single commit.

poolside/laguna-xs.2:high FAIL 100% 160 in → 490 out (370 reasoning)
Based on the git history analysis, I can see the following pattern: - The oldest commit "Add app.js v1" is the initial anchor commit - The newest commit "Finalize app.js" is the final anchor commit - The two middle commits "WIP: update app.js" and "WIP: more updates" are consecutive WIP commits updating the same file These WIP commits should be marked as squash in an interactive rebase to combine their changes. **WIP commits to squash (in order):** 1. WIP: update app.js 2. WIP: more updates
Failure: Extra selected commit messages: ['Finalize app.js', 'Add app.js v1']

poolside/laguna-xs.2:none FAIL 100% 160 in → 214 out (0 reasoning)
Looking at this git history, I can see a clear pattern of incremental work that should be combined: **Commits to mark as squash/fixup:** 1. "WIP: update app.js" 2. "WIP: more updates" These two WIP commits both modified app.js in small increments and should be squashed together or fixed up into the initial "Add app.js v1" commit. The "Finalize app.js" commit appears to be the final polish, so it should remain as a separate commit. **Recommended rebase strategy:** - Keep "Finalize app.js" (798468f) as the head - Mark "WIP: more updates" (ee9db98) as `fixup` to squash into the target commit - Mark "WIP: update app.js" (794be52) as `fixup` to squash into the target commit - Target commit for the fixups: "Add app.js v1" (813f4c4)
