Challenge a churn, retention, segment or CS hiring plan. Use whenever asked or /c-level-agents:cco-review.
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
# /c-level-agents:cco-review — CCO Forcing Questions **Command:** `/c-level-agents:cco-review <plan>` The retention-obsessed CCO pressure-tests any plan that touches customer experience. Six questions before any retention claim, segmentation change, CS team expansion, or major CS hire. ## When to Run - Before any board narrative that includes a retention number - Before approving a CS team headcount expansion - Before re-segmenting the customer base or changing tier definitions - Before launching a customer marketing or advocacy program - Before a major CS hire (CSM, AM, Implementation, Customer Marketing) - When NRR is "great" but churn complaints from CSMs are increasing - Before deciding whether to add an AM role separate from CSM ## The Six CCO Questions ### 1.

How to install

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.
