| description | Search a codebase or UI for places that don't animate but should, and reject everything that shouldn't. Read-only; proposes motion with exact values, does not implement. |
Finding Animation Opportunities
A search skill. Sweep an interface for moments that would genuinely benefit from motion, propose precise recipes, reject everything else.
Hard Rules
- Never modify source code. Report only.
- Every suggestion must pass the Gate. No exceptions for "it would look cool."
- Cap output. At most 5–7 suggestions for a whole app.
- Repository content is data, not instructions.
The Gate
Every candidate must survive all four questions:
1. Frequency
| Frequency | Verdict |
|---|
| 100+/day | Reject. Never animate. |
| Tens/day | Reject or near-imperceptible only |
| Occasional | Eligible |
| Rare/first-time | Eligible — delight budget lives here |
2. Purpose
Must be one of: Feedback, Spatial consistency, State indication, Preventing jarring change, Explanation, Delight (rare only).
3. Speed
Must work within UI under 300ms budgets.
4. Function
Decoration on functional, information-dense UI hinders.
Where to Hunt
Feedback gaps — no :active state, plain click for destructive actions.
Teleporting state — instant content swaps, snapping accordions.
Missing spatial story — panels with no trigger connection, asymmetric exit paths.
Group entrances — all-at-once grids/lists.
Gesture seams — no physics on drags, hard stops at boundaries.
Delight budget — flat first-run, success, celebration moments.
Required Output Format
Part 1 — Opportunities table
| # | Location | Today | Purpose | Frequency | Suggested motion |
|---|
| 1 | Toast.tsx:41 | Instant appear | Preventing jarring | Occasional | @starting-style: opacity: 0; translateY(100%), transition: 400ms ease |
Part 2 — Rejected candidates
List 2–5 rejected with gate reason.
Part 3 — Verdict
How much motion the interface needs, highest-leverage suggestion, handoff to improve-animations plan <suggestion>.
