The prompt

Written to be pasted straight into an agent with no editing. It describes the whole job, including the parts that will go wrong.

Build a feature support matrix. Ingest a versioned dataset of features against platform versions with support values of yes, no, partial and prefixed. Homepage is a search over feature names and aliases; each feature gets a page at /:feature showing a grid of platforms by version, usage-share weighting for a computed global support percentage, notes per cell, and links to the spec and to bug trackers. Support a shareable embed. Load the dataset from a published package so updates are a dependency bump rather than a scrape.
Open inClaude ↗Terminal agents take it from the clipboard.

What copies cleanly

  • The table, the search, the per-feature page. It is the original layout and it is not complicated.
  • The data, in fact, which is openly licensed and published as a package you can install.

Where it stops

  • The data is the product, and the data is maintained by hand, continuously, as five browser engines ship every six weeks.
  • A stale support table is worse than no support table, because someone will trust it.
  • You would be signing up for a permanent job, not shipping a project.

What actually protects them

  • Fifteen years of curation and the trust that comes with being right.
  • It is the answer to a question developers ask several times a week, so it never has to acquire anyone.

Editor's note

The honest ancestor of this entire genre, including us. Its lesson is the one every copy of it eventually learns: the table was never the hard part.
