errors-slips

Use this skill when designing to prevent or recover from execution errors — actions that don't match the user's intent. Trigger when designing critical action confirmations, distinct affordances for similar-purpose elements, recovery from wrong-button presses, "I didn't mean to do that" flows. Sub-aspect of `errors`; read that first.

# Slips: errors of execution

A slip happens when the user knew what they wanted to do but their action didn't match. The intent was right; the execution was wrong. Slips are common in routine tasks where conscious attention has lapsed: the user types "definately" instead of "definitely," clicks Reply when they meant Reply All, deletes the file they meant to keep.

The design responses for slips don't increase the user's knowledge — the user already knew what to do. They make wrong actions structurally harder, give clear feedback when they happen, and provide easy recovery.

## The two slip subtypes (from the book)

### Action slips

Wrong action despite correct intent. Triggered by:

- Routine tasks performed automatically.
- Distractions or interruptions.
