Adds pre-push readiness skill by camsim99 · Pull Request #11935 · flutter/packages

camsim99 · 2026-06-18T15:07:03Z

Adds a new pre-push-skill skill that verifies changes made to a packages are ready to be "pushed", i.e. the committed changes could successfully be made into a pull request that follows the requirements of the flutter/packages repository (including some of the items in the checklist below).

Pre-Review Checklist

+dart run script/tool/bin/flutter_plugin_tools.dart \
+ format --run-on-changed-packages
+```


Just saw that we could also use the --set-exit-if-changed option. But we could format directly since it might help the developer. @LouiseHsu what do you think?

I think what you have is good already!

I think it depends on what you want the scope of this skill to be. My gut says that the skill should not format but instead should say that formatting changes were found. That way one of the evals we can run is "did any files change when running this skill" and enforce that the answer is no. But that only makes sense if the skills "check pre push" skill and not a "prepare for push" skil. So it comes down to a scope question.
Second we are designing this as a system. The precommits should handle formatting(and analyze) so maybe the right answer is to do no formatting checks.

So from what I remember, skills are invoked only based off the description and the name. So maybe you can make the desc more detailed? something like
"Executes the required pre-push steps for the flutter/packages repository. Call this tool immediately whenever the user asks to push, requests a code review before committing, or wants to validate their local changes for a pull request. Do NOT use this tool if the user is working in flutter/flutter or flutter/engine."

I see. Good call, I like your description! Updated it.

Code Review

This pull request adds a new markdown document, SKILL.md, defining the pre-push validation steps and checklist for the flutter/packages repository. The review feedback suggests two improvements to the instructions: first, recommending that developers commit rather than stash their changes during the initial working tree check to ensure latest changes are validated; and second, clarifying that any auto-generated changes in the final check should be committed rather than discarded.

I am not sure this should trigger on request for "code review before committing". Consider instead

Why did you need "flutter/flutter#188373"? This skill should be loaded locally so it should not leak to those environments.

Accepted minus the notes on engine/framework

+## 3. Format Code
+
+Consistent code style is required for all pull requests.
+The repository uses auto-formatters (like `dart format`, `clang-format`)


Not not but maybe later we should reference the check-readiness skill to ensure the formatters are on path and acceptable.

again this is a place where we could simplify the command if we scoped it to camera_android_camerax

This also has the semi dangerous assumption that main was not broken and that we are merging back into main. Those assumptions are probably fine for a first version of the skill but we might want to articulate a more nuanced version.

Updated this to include more nuance. We could do a more technical step where we have the agent check if it was failing before but I consider that a bit out of scope.

Lets make a call on if this skill is only about evaluating if the changes are ready to push or if its scope it to actually make the changes.

reidbaker · 2026-06-23T17:25:40Z

Meta comments:
We need to decide if file changes are part of this skill or if this skill has no file changes and instead the agents responds to failures like a test.

Decided that this should just be a skill that verifies the state of code versus applies fixes. We can change that later on but I don't think we should introduce the complexity of fixes for now.

camsim99 · 2026-06-23T23:00:15Z

@reidbaker Re-wrote this quite a bit to focus this skill on verifying code is ready to push versus making automatic fixes and only on the camera_android_camerax package. PTAL!

Really good changes!

One thing this skill does not have is a list of assumptions about what is available on the path. Not a requirement for now but I wanted to point that out since I noticed. Here is an example from flutter/flutter. https://github.com/flutter/flutter/blob/master/.agents/skills/flutter-pr-checks-finder/SKILL.md#prerequisites

Added gh because we require it for making a PR :)

Thanks this works. I think long term we want check readiness to cover our tool requirements.

reidbaker · 2026-06-24T14:14:49Z

+ give the user a quote from the testing documentation
+ on what type of test is required for their changes.
+ Beyond the rubric, if you think the change does not meet
+ the documented quality bar, tell the user


non blocking. We should standardize on how we refer to the person operating the agent/skill/chat and document that in the readme for this folder.

Added a note in the README!

reidbaker · 2026-06-24T14:24:52Z

+ (for example, `[camera_android] Fix crash`
+ or `[camera_android, camera_android_camerax] Fix crash`
+ if both `camera_android` and `camera_android_camerax` were modified).
+- BODY is the PR description that should contain a link


Later I think we will delegate pr descriptions to a skill but this is good.
Lets make the body of the pr follow the file https://github.com/flutter/packages/blob/main/.github/PULL_REQUEST_TEMPLATE.md. You can link it as a relative path from this directory.
