Build an ARR waterfall from your MRR export
See where your ARR came from and where it went each month: new, expansion, contraction, churn, and reactivation, with NRR and GRR. A script builds it from a subscriptions or MRR-by-customer CSV, so the numbers are repeatable and tie out, and writes markdown, CSV, and a per-customer movements file. Works offline.

- Works out of the boxOur guess from what the kit says it needs.
- Works in
- Claude Code, claude.ai and the desktop app
- You need
- Nothing else. Add it to Claude and ask.

- What it touches
- Reads ./data/**, writes to ./out/arr-waterfall* and runs node scripts/arr-waterfall.mjs

How this works
- It is a skill: written instructions Claude reads when your request matches what the skill is for. You do not call it by name; just ask for the task.
- While it works, it reads and changes files in the places it lists, nowhere else.
- It runs these commands on your computer: node scripts/arr-waterfall.mjs.
- Nothing runs until you choose to use it, and you can remove it any time.
What it can access
What this kit says it will touch, the same list you see before you add it. These are its Permissions: What a kit is allowed to touch on your computer or accounts, such as reading a folder or using the internet. You see them before you add it.. In Claude Code they become rules, so Claude stops anything not on the list.
Command
Runs the command: node scripts/arr-waterfall.mjs (with any arguments, without asking)
Reads
Reads files in ./data/**
