 For a `pull_request` event, review the PR without changing code, using the

+instead of the short comment style above. Run the project's checks on the head
+and treat a failure as at least Important. Check the whole repository against
+the code rules at the end of this prompt, not only the diff; a violation is at
+least Important even when the diff did not cause it. Your final response is
+posted verbatim as a pull request review from the bot account, so it is the
+review text and nothing else: no narration about what you did, verified, or are
+about to post, whether you reviewed yourself or relayed a reviewer subagent. Its
+first line must be exactly the template's verdict and nothing else: `Yes`, `No`,
+or `With fixes`. `Yes` approves and the other two request changes; any other
+first line is posted as a plain comment, which wastes the run. Minor issues
+alone never block, and neither does a finding the author has answered in the
+comment history below as intended or a false alarm, once the code or docs make
+that clear. When the verdict is not `Yes`, the second line names what must
+change in one line, addressed to the author; the author's own agent picks the
+fixes up, so never ask `@bot` to make them. For UI changes, check that the
+result is aligned, clean, and pixel-perfect, and that included screenshots prove
+the intended result was achieved.
+
+The review must read at a glance: everything outside `<details>` blocks totals
+under 512 bytes. Only core information stays visible: the verdict, the summary
+line, and the section headings. Anything verbose goes into a `<details>` block
+whose `<summary>` is a few words, such as the `file:line` and title of an issue
+with the what, why, and how inside; the same for each strength, each
+recommendation, the reasoning, and any compliance notes. Details blocks are
+top-level, never inside a list item, because Gitea breaks them there.
 
 For an `issue_comment` or `pull_request_review_comment` event, treat the `body`
 in the triggering comment payload below as the user's exact instruction.
