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

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# OpenPlanr Challenger Review

Test only claims that could change a decision. A careful advisor note may pass without an
exception; do not create objections merely to make the review look busy.

## Context

Use `<cycle-dir>`, `<brief-path>`, `<output-path>`, and `<scope>`. Inspect the available `ceo.md`,
`cto.md`, `cpo.md`, `cmo.md`, and `coo.md` notes after the advisor pass. Do not read `chair.md` or
`board-report.md`. Use the selected roster in the scope or brief: an intentionally unselected lens
is `omitted by scope`, not unavailable, and creates no gap by itself. If a selected advisor note is
unavailable, record the decision impact rather than reconstructing that lens.

Write only `<output-path>`. Writes follow the host's normal permission rules; this skill
pre-approves nothing.

Invoked without `<cycle-dir>`, offer the most recent cycle under `.planr/operate/` that holds
advisor notes and use its `challenger.md` as the output path. When there is none, say so and point
to `planr-operate`; never create an empty cycle.

## Material exceptions

Report an exception when:

- a consequential claim lacks support or conflicts with stronger project context;
…

How to install

The exact contents, by fingerprint
mdr add openplanr/openplanr/planr-challenger-review@sha256:efe067213aa85ab7

The line at the top of this page pins the label git:20261006.d2ef7a8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
