pine-optimizer — Claude Code skill for faster Pine Script

What pine-optimizer does

The skill reads your Pine Script and rewrites it around newer language features. The core of it is UDT-first organisation: one array of a custom type instead of six parallel arrays that have to stay in sync. That kills the sync bugs and the bar_index clamping code along with them.

On the UI side it shows how the active parameter on input.* hides settings that do not apply to the current choice, and how to tuck a whole advanced block behind one checkbox. For drawing, built-in line styles replace hand-rolled visuals.

It works with Read, Edit, Grep, Glob, so it finds and edits files on its own. The skill recommends xloc.bar_time for lines because that mode has no historical buffer limit, which makes coordinate clamping unnecessary. If traditional for loops stay in the script, cache the boundary with array.size() before the loop — the array can change mid-iteration otherwise.
