Version 0.21.13 adds worktree locks and session IDs so concurrent AI reviewers stop destroying each other's work.
Why now: August 17's release notes are the first detailed public account of what breaks in review agents run at scale.
Qwen Code shipped version 0.21.13 on August 17, capping review suggestions to Critical findings after five rounds, per GitHub's release notes. Teams running review agents at scale pay for that gap: infinite loops, sessions overwriting each other's review state, corrupted checkouts that kill a run. Few vendors document these failures publicly. This changelog does.
The /review skill got rebuilt around dedicated platform subcommands, meta and fetch-diff, instead of raw gh commands issued through prompt prose. Stringing shell commands together inside natural-language instructions turned out to be fragile in ways a typed subcommand isn't.
Worktree leases now act as locks, so two concurrent review sessions can't destroy the same active review state. A corrupted checkout triggers an automatic wipe and retry instead of leaving a broken session behind. Session IDs plus diff hashes track which agent did what, so work survives an interrupted run.
That worktree lock fixes a symptom, not the cause: raw gh commands issued from prompt text, which any agent-review tool will hit eventually. Worth watching: whether other agent-review tools ship the same fix, or find the same failure first.
These release notes are the first detailed public account of what breaks in review agents run at scale, published August 17.
