Wrote the README and stopped the prerequisites file from lying about itself

The repo had no README and prerequisites.md was three stray lines (axios, node-cron, fs) that didn’t actually match what package.json declared or what main.js fails fast on at boot. Rewrote prerequisites.md as a pure library install reference — packages, versions, and one npm install command — then wrote a README that follows the structure the Stardance judges actually want: one-sentence description, hero image slot, a try-it link, quick start, features, local setup, and a “how it works” section that earns its keep by naming real decisions (Socket Mode over HTTP so it runs behind any network, self-rescheduling crons with re-rolling fire times, file-locked JSON as a tiny DB instead of SQLite, sequential Groq calls to dodge rate limits).

The friction was the Node version. There’s no engines field in package.json and no .nvmrc, so I didn’t want to just assert “Node 18+” without evidence. Grepping package-lock.json for "engines" turned up ~100 matches and the binding constraint is @slack/bolt‘s transitive deps all declaring "node": ">=18" — so that’s the honest floor, stated as such.

Also swapped the watched channel ID in Code/main.js from C0BBBCER55W to C09F6AAP1PF to match the workspace in the invite link I was handed. Caught one real issue while reviewing: the “Try it” link was a channel permalink (/archives/C09F6...), which a non-member hits a sign-in wall on, flagged it, left it in since it’s an internal members link.
