 Released on 2025-10-23.
--- a/CONTRIBUTING.md

@@ -280,55 +280,6 @@ Note that plugin-specific configuration options are defined in their own modules

 Finally, regenerate the documentation and generated code with `cargo dev generate-all`.

-### Opening a PR
-
-After you finish your changes, the next step is to open a PR. By default, two
-sections will be filled into the PR body: the summary and the test plan.
-
-#### The summary
-
-The summary is intended to give us as maintainers information about your PR.
-This should typically include a link to the relevant issue(s) you're addressing
-in your PR, as well as a summary of the issue and your approach to fixing it. If
-you have any questions about your approach or design, or if you considered
-alternative approaches, that can also be helpful to include.
-
-AI can be helpful in generating both the code and summary of your PR, but a
-successful contribution should still be carefully reviewed by you and the
-summary editorialized before submitting a PR. A great summary is thorough but
-also succinct and gives us the context we need to review your PR.
-
-You can find examples of excellent issues and PRs by searching for the
-[`great writeup`](https://github.com/astral-sh/ruff/issues?q=label%3A%22great%20writeup%22)
-label.
-
-#### The test plan
-
-The test plan is likely to be shorter than the summary and can be as simple as
-"Added new snapshot tests for `RUF123`," at least for rule bugs. For LSP or some
-types of CLI changes, in particular, it can also be helpful to include
-screenshots or recordings of your change in action.
-
-#### Ecosystem report
-
-After opening the PR, an ecosystem report will be run as part of CI. This shows
-a diff of linter and formatter behavior before and after the changes in your PR.
-Going through these changes and reporting your findings in the PR summary or an
-additional comment help us to review your PR more efficiently. It's also a great
-way to find new test cases to incorporate into your PR if you identify any
-issues.
-
-#### PR status
-
-To help us know when your PR is ready for review again, please either move your
-PR back to a draft while working on it (marking it ready for review afterwards
-will ping the previous reviewers) or explicitly re-request a review. This helps
-us to avoid re-reviewing a PR while you're still working on it and also to
-prioritize PRs that are definitely ready for review.
-
-You can also thumbs-up or mark as resolved any comments we leave to let us know
-you addressed them.
