**When confused, search `docs/` first.** Key reference: `docs/development/debugging/gotchas/`

Load Skill('pattern-critic') for the full violation checklist.

## Goal

Quickly scan for common mistakes. Focus on what breaks at runtime.

## High-Priority Checks

1. **Module scope** — `handler()` or `lift()` inside pattern body? Move to module scope.
2. **Reactivity** — `[NAME]: prop` without `computed()`? Reactive value in `Writable.of()`?
3. **Conditionals** — Ternary for elements? Use `ifElse()` instead.
4. **Binding** — Missing `$` prefix on `checked`/`value`?

## Output

Just list what's wrong with line numbers and fixes:

```
## Issues in [filename]

1. [Line 10] Reactive [NAME], `Study: ${deck.name}`, should use computed — [NAME]: computed(() => `Study: ${deck.name}`),
2. [Line 15] `handler()` inside pattern — move to module scope
