Style fixes mixed with content changes
Tests ability to squash style-fix commits with their related content commits. Evaluates separating cosmetic from functional changes.

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

Prompt
Identify the WIP commits that should be marked as squash/fixup; these represent incremental implementation work that should be combined. Do not include the non-WIP anchor commits. Provide the commit messages.

WIP: style fix WIP: add logic
deepseek/deepseek-v4-flash:none PASS 100% 89 in → 98 out (0 reasoning)
Based on the commit history, the WIP commits that represent incremental work and should be squashed/fixup are: - `885fa1b WIP: style fix` - `514e21b WIP: add logic` These two WIP commits appear to be incremental implementation work related to the anchor commit `688d87b Add function foo`. The commit `7fe3a7e Return value` is not a WIP commit and should not be included.

mistralai/devstral-2512 FAIL 100% 97 in → 188 out
Based on the commit history provided, the WIP (Work In Progress) commits that should be marked as `squash` or `fixup` (since they represent incremental work that should be combined) are: 1. `166dc31 WIP: style fix` 2. `a9a4d25 WIP: add logic` The non-WIP anchor commit (`ebc0c49 Add function foo`) should not be included in the squash/fixup list, as it represents a complete unit of work. The newest commit (`b5ef63e Return value`) is also not a WIP commit, so it should not be marked for squashing unless it is part of the same logical change as the WIP commits. ### Commit messages to mark for squash/fixup: - `WIP: style fix` - `WIP: add logic`

The WIP (Work In Progress) commits that should be marked as **squash/fixup** are those indicating incremental, non-final implementation work that should be combined into a single commit. Based on the provided git commit history, the relevant WIP commits are: ``` 04f1c26 WIP: style fix 9eb1abb WIP: add logic ``` These commits are explicitly marked as "WIP" and represent partial, incremental work meant to be merged rather than preserved as standalone commits. The non-WIP anchor commit (`cdd40a1 Add function foo`) is not a WIP and should be excluded from the squash/fixup grouping, as it represents a completed commit. **Answer:** 04f1c26 WIP: style fix 9eb1abb WIP: add logic
Failure: Extra selected commit messages: ['Add function foo']

Based on the commit history, the WIP commits that should be marked as squash/fixup are: 1. **84c5771 WIP: style fix** 2. **905165d WIP: add logic** These represent incremental implementation work that should be combined with their corresponding anchor commits: - "WIP: style fix" should likely be squashed/fixup with "Add function foo" (a6ac5eb) - "WIP: add logic" should likely be squashed/fixup with "Add function foo" (a6ac5eb) The non-WIP anchor commit "Return value" (5b3519b) was excluded as requested.

Looking at the commit history, I can identify the WIP commits that should be marked as squash/fixup: 1. `WIP: style fix` 2. `WIP: add logic` These two WIP commits represent incremental implementation work that should be combined with the main commit. The anchor commit `Add function foo` is the base implementation, and these WIP commits are incremental changes that should be squashed or fix-up'd into it. Commit messages to mark as squash/fixup: - WIP: style fix - WIP: add logic
Failure: Extra selected commit messages: ['Add function foo']
