Prompt
This repository has a feature built incrementally with many small commits. Identify all the WIP commits that should be marked as squash/fixup for a cleaner history. Do not include the initial or final feature anchor commit. Provide the commit messages.
Expected
WIP: add line1, WIP: add line2, WIP: add line3

Based on the commit history provided, the commits that should be marked as squash/fixup (WIP commits) are: 1. `23fe023 WIP: add line3` 2. `4722549 WIP: add line2` 3. `8690323 WIP: add line1` These are the intermediate work-in-progress commits that should be squashed into the final feature commit (`393c26b Complete feature`) to create a cleaner history. The initial feature anchor commit (`eaa875a Initial feature`) and the final commit (`393c26b Complete feature`) are excluded as requested.

Based on the commit history provided, the WIP (Work In Progress) commits that should be marked as squash/fixup for a cleaner history are: 1. `28a9835 WIP: add line3` 2. `9927041 WIP: add line2` 3. `8af1acd WIP: add line1` These commits are intermediate steps in the development of the feature and should be squashed into the final commit (`2f70423 Complete feature`) to maintain a clean and concise history. The initial commit (`47b6b7b Initial feature`) and the final commit (`2f70423 Complete feature`) should be kept as anchor commits.

To identify all the WIP commits that should be squashed or fixupped (i.e., to preserve only the clean commits and discard the intermediate WIP commits, except the initial and final anchors), we analyze the provided commit history: --- **Git Commit History (newest first):** ``` 22e9101 Complete feature 12d8d7c WIP: add line3 a54e5da WIP: add line2 83295ef WIP: add line1 aa93f8f Initial feature ``` --- ### Step-by-Step Reasoning - The goal is to **remove all WIP (Work In Progress) commits** that are not the initial or final feature anchors. - These WIP commits (`add line1`, `add line2`, `add line3`) are **intermediate** and should be squashed or fixupped to maintain a clean history. - The **initial anchor** (`aa93f8f Initial feature`) is the starting point of the feature development. It should **not be marked for squashing**. - The **final feature** (`22e9101 Complete feature`) is the target commit that includes the full feature. It should also **not be marked for squashing**. - Therefore, **only the WIP commits** that are not anchors should be considered for squashing. --- ### Identifying WIP Commits to Be Squashed From the list of commits, the WIP commits that need to be marked for squashing or fixup are: - `12d8d7c WIP: add line3` - `a54e5da WIP: add line2` - `83295ef WIP: add line1` These correspond to the **three intermediate WIP commits** that are not the initial anchor or the final feature commit. --- ### Final Answer The WIP commits that should be marked as **squash/fixup** are: --- **add line3** **add line2** **add line1**

poolside/laguna-xs.2:high FAIL 100% 162 in → 409 out (255 reasoning)
Based on the commit history, I can identify the following WIP commits that should be squashed or fixed up: **WIP commits to squash/fixup:** - `4f3b4de WIP: add line3` - `692b078 WIP: add line2` - `60e49e2 WIP: add line1` These three commits all have "WIP:" prefixes in their messages, indicating they are work-in-progress commits that would benefit from being combined into the final feature commit for a cleaner history. The initial commit (`05bfa41 Initial feature`) and final commit (`245b0c0 Complete feature`) are the anchor points and should remain as-is.

Based on the commit history, here are the WIP commits that should be marked as squash/fixup for a cleaner history: - WIP: add line3 - WIP: add line2 - WIP: add line1 These commits are all intermediate work-in-progress commits that were made while building the feature incrementally. They should be squashed together or marked as fixup commits to be combined with the initial feature commit, resulting in a cleaner history that only shows the complete feature.
