# OpenPlanr Challenger Review

Skill family: Operate synthesis.

Challenge an Operate cycle's claims, alternatives, downside, and confidence. Use when assumptions or executive consensus need an independent stress test.

## Run it

- Claude Code: `/challenger-review`. If /challenger-review runs another command, use /planr:challenger-review.
- Codex: `$challenger-review`. With the OpenPlanr plugin for Codex, use $planr:challenger-review.
- Cursor: `@planr-challenger-review`. Cursor applies the planr-challenger-review rule when you mention it in chat.

## Use it to

- Challenge operating-review assumptions and downside
- Test material claims, alternatives, confidence, and dissent

## Not for

- Summarize reviews without challenging them
- Implement a proposed decision
