ℹ︎ How to read this score
Signals, not verdicts. A ghost score (0–100) estimates the probability that a repository will go 12 months without a non-bot commit, become archived, or be deprecated. A high score is a prompt to check your dependency health — never an accusation against its maintainers.

coffee-script

“A pioneer that brought elegance and accessibility to the early JavaScript ecosystem. Its legacy continues through the evolution of the language it helped shape.”

epitaph by gemma-aistudio/gemma-4-31b-it · model heuristic-v1 · signals, not verdicts · snapshot from 2026-10-29

Last words: “Fix Windows invocation parsing test spawn (#5508)”

Hold a seance

The spirit of coffee-script answers strictly from its own records — README, releases, and issues. It never impersonates a maintainer and says “I don't remember that” when evidence is missing.

The candles are lit. Pick a question above or ask what coffee-script did, how to migrate away, or how it ended.

Lighting the candles for maintainer support links…
