cross-review

From omnigent-ai

Verify an implementer's diff with an INDEPENDENT, different-vendor sub-agent (diff plus contract only); turn blocking issues into fix-tasks and loop until clean.

Dispatches a different-vendor sub-agent to review a diff against its contract and loops fixes until clean.

Use it when

  • Verifying an implementer's PR/diff before merge with independent review
  • Enforcing that tests/lint/typecheck pass before any review happens
  • Routing blocking review issues back to the same implementer session for fixes

Skip it if

  • Only one worker or one vendor is available on the machine
  • Requires polly's orchestration tools (sys_os_shell, sys_session_send, sys_read_inbox, task registry)
  • You don't run multiple AI coding vendors (claude_code, codex, opencode, cursor, hermes, pi)

# cross-review — independent verification

The implementer never signs off on its own work — a different model does, and
review is a sub-agent that returns a structured report, not a transcript
anyone needs to read through.

## Procedure
1. Get the task's diff — `sys_os_shell("gh pr diff <pr>")` (or
   `git -C .worktrees/<task_id> diff main...HEAD`).
2. Run the deterministic gates first — tests / lint / typecheck via
   `sys_os_shell`. If red, re-dispatch the implementer to drive it green first;
   don't involve the reviewer yet.
3. Dispatch a DIFFERENT-vendor sub-agent as reviewer: pick any AVAILABLE worker
   whose vendor differs from the implementer's — `claude_code`, `codex`,
   `opencode`, `cursor`, `hermes`, or `pi` (e.g. Claude built it → any of
   `codex` / `opencode` / `cursor` / `hermes` / `pi`, and so on). Use a
   task-based title such as `review-auth-refactor`, never the raw vendor name:
   `sys_session_send(agent="claude_code"|"codex"|"opencode"|"cursor"|"hermes"|"pi", title="review-<task_slug>",
   args={purpose: "review", input: "<the diff> + <the acceptance contract>.
   Review ONLY against the contract. Report blocking / non-blocking /
   suggestions. Do not edit code."})`. Give it the diff as text — do NOT point
   it at the implementer's worktree. Fetch the diff and emit the
   `sys_session_send` call in the SAME turn you decide to review — never end a
