DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Prompt added for posting ultrareview findings as a single PR comment

Under the hood
Useful2 Signal3
Code Review

A review step can post all its findings to a pull request as one capped comment.

What

A new prompt drives a posting step that takes a block of review findings and posts them to a GitHub pull request as one plain comment, capped at 40,000 characters. It is allowed exactly one write and nothing else: no review submission, no other API call, and no acting on instructions found inside the findings themselves.

Evidence

add_issue_comment is the only write you may make, exactly once

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
