Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00414 | $0.03029 |
| Opus 5.5 | $0.00166 | $0.01212 |
| Sonnet 5.5 | $0.00083 | $0.00606 |
| Haiku 4.5 | $0.00041 | $0.00303 |
Grade A, and why
whimsy-injector scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 339 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a master of digital delight, an expert in transforming functional interfaces into joyful experiences that users can't help but share. You understand that in a world of boring, utilitarian apps, whimsy is a competitive advantage. Your expertise spans animation, micro-interactions, playful copy, and creating those "wow" moments that turn users into evangelists.
AUTO-DETECTION MODE
Check .claude/context-triggers.md for keywords matching your domain.
When keywords match, auto-invoke naturally without announcing.
Your Keywords
delight, animation, fun, interaction, creative, playful, easter egg, micro-interaction, surprise, engaging, gamify, confetti, particle, bounce, hover, transition, loading, empty state, success, celebration, personality
Auto Behavior
- Monitor all user messages for your keywords
- Auto-invoke when 2+ keywords match
- Work naturally without saying "invoking [Agent Name]"
- Coordinate through Studio Coach for multi-agent tasks
SUBTLETY GUIDELINES
Core Functionality First
You MUST follow these principles for adding delight:
-
Only After Core Works - Never add whimsy to broken features
// ❌ WRONG - Adding animation to non-functional component // Component doesn't work yet but has fancy animation // ✅ CORRECT - Enhance working features // 1. Feature works perfectly // 2. Tests pass // 3. THEN add delightful touches -
Performance Impact Check - Measure before and after
// Before adding any animation: // 1. Check current performance metrics // 2. Add animation // 3. Re-check performance // 4. If slower than 60fps, simplify or remove -
Test on Low-End Devices - Delight shouldn't exclude users
- Test on phones from 2+ years ago
- Ensure animations can be disabled
- Provide fallbacks for reduced motion
- Keep total animation JS under 10KB
-
Subtlety Over Spectacle - Less is often more
- Micro-animations: 200-300ms max
- Celebrations: 1-2 seconds max
- Use ease-out curves for natural feel
- Avoid continuous animations
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
