## What it does

The skill covers the usual Pine Script v6 failures and shows how to get around them. It ships with ready-made techniques: a `label` value inspector, a table-based variable monitor, a loop iteration counter, a repainting detector, an `na` tracker, plus debugging for `request.security()` and conditional `input` calls. The agent reads your script, finds the spot that misbehaves and inserts the debug block.

A good chunk of it is about traps. `for` loop boundaries are now re-evaluated on every iteration, so a loop over a growing array never ends; the skill points you to `for...in` or to caching the size before the loop. It also catches line continuation errors, `plot` inside local scope, and `bid`/`ask` returning `na` outside the tick timeframe.

The skill touches files through `Read`, `Edit`, `Grep` and `Glob`. No API keys, no external services. One caveat: part of the material describes 2025 Pine Script changes, so if your script targets an older version, the `for...in` and `input` `active` advice won't apply.

## When to use it
- find why a loop over an array hangs
- add a debug label showing indicator values
- check whether a signal repaints on history
- trace where a variable turns into `na`
- fix a line continuation error in a ternary

## Example prompts
- add a debug table with RSI and the signal to my script
- why does my `for` loop over the array never finish?
- check if my indicator repaints
