surge-retention skillA
surge-retention is agent-read markdown (skill) from jeremylongshore/tons-of-skills-marketplace: Retention diagnosis + intervention plan — analyze the retention curve, identify the primary drop-off point, and produce a specific intervention plan with expected impact. Use when asked to "improve retention", "why are users churning", "build a retention playbook", "reduce churn", "win-back campaign", or "users aren't coming back"..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add jeremylongshore/tons-of-skills-marketplace/surge-retention@v0.6.4mdr add jeremylongshore/tons-of-skills-marketplace/surge-retention@sha256:427d5f9e4161cc88Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
