Galley

About

Unattended agent work fails when the same model both writes and grades the code. Galley is a Go CLI and daemon that takes a task YAML with acceptance criteria, runs an executor backend — Claude Code, Codex, or Grok Build — inside an isolated worktree, then has a separately configured supervisor model review the result against those criteria before opening a PR. Executor and supervisor pairs are set per task or repo, evidence files capture diffs, model output, and verdicts for audit, and retry budgets bound runaway sessions. It installs as a marketplace skill for Claude Code, Codex, and Grok Build, and roughly half of Galley's own merged PRs were produced by Galley-managed task branches.
