| # Single-agent PR review using the prompt in .github/prompts/code-review.md. | ||
| # | ||
| # Measured on a frozen dataset of 122 hyperdxio/hyperdx PRs where a human left a | ||
| # substantive inline review comment (harness: hdx-code-reviewer). On the held-out test | ||
| # split, Opus, 49 PRs / 87 gold items: | ||
| # this prompt 40% recall, $3.11/PR, 1 agent | ||
| # deep-review (multi-agent, in production) ~22-33% recall, 6-13 agents | ||
| # On the larger shared slice the two are within noise of each other, so the claim is | ||
| # parity-or-better at one agent instead of six-to-thirteen -- not a 4x improvement. | ||
| # | ||
| # Findings are posted as INLINE review comments where the finding's line is part of the | ||
| # diff, plus one sticky summary comment that is updated in place across pushes. Findings | ||
| # that cannot be anchored to a diff line (they reference an unchanged file the reviewer | ||
| # opened) fall back into the sticky comment body. | ||
| # | ||
| # Minor-severity findings are folded behind a <details> block rather than dropped: | ||
| # measured on this dataset, minor findings carry 29-57% of all gold matches, so filtering | ||
| # them would cost roughly half the recall. Severity is for ordering, not filtering. | ||
