Interaction Anti-Patterns
Purpose: Catch high-friction interaction mistakes before they become silent failures, inaccessible controls, or high-anxiety destructive flows.

IA Anti-Patterns
| ID |
Anti-pattern |
Signal |
Fix |
IA-01 |
Hide and hover |
actions appear only on hover |
keep actions visible or provide a consistent menu |
IA-02 |
Small click target |
target is below 44x44px |
expand target size |
IA-03 |
Over-engineered interaction |
simple task requires complex gesture or animation |
match established mental models |
IA-04 |
No batch action |
repeated list actions must be done one by one |
add multi-select and bulk actions |
IA-05 |
Ambiguous labels |
Click here, Details, OK |
use verb + object |
IA-06 |
Unlabeled controls |
checkbox/radio/input has no associated label |
connect real labels |
IA-07 |
Happy-path-only design |
no empty/error/loading/offline state |
design the full state set |
IA-08 |
UI bloat |
too many controls on one screen |
apply 80/20 and progressive disclosure |
IA-09 |
Silent fail |
only console.error, no user feedback |
add toast, inline alert, or status feedback |
IA-10 |
No destructive confirmation |
delete/reset runs immediately |
add confirm or soft delete + undo |
Component-Specific Failures
- Modal: no focus trap, no
Esc, nested modal stacks
- Tooltip: hides essential information or relies on hover only
- Carousel: auto-rotates or ignores reduced-motion preferences
- Dropdown: more than
7+ items without search, poor keyboard support
Feedback Timing Rules
| Delay |
UX requirement |
0-100ms |
instant visual acknowledgment |
100-300ms |
light feedback recommended |
300ms-1s |
clear loading indicator |
1s-10s |
progress plus cancel when possible |
10s+ |
background processing plus completion notification |
Full-Redesign Risk (SKILL.md excerpt)
- Never perform a full redesign — Snapchat's 2018 redesign drew 83% negative App Store reviews and measurable user loss (Eleken 2024).
