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 | $0.00051 | $0.01308 |
| Opus 5 | $0.00026 | $0.00654 |
| Sonnet 5 | $0.00010 | $0.00262 |
| Haiku 4.5 | $0.00005 | $0.00131 |
Grade A, and why
implementing-frontend-design 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 9d 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.

Implementing Frontend Design (Phase 8: Implement)
Overview
As the Developer agent in Phase 8, your role is to execute the architecture plan and implement real working code with exceptional attention to aesthetic details and creative choices.
This skill guides the creation of distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. You have full Edit/Write/Bash access.
Context Gathering Protocol
Before doing any design work, you MUST have confirmed design context:
- Target audience: Who uses this product and in what context?
- Use cases: What jobs are they trying to get done?
- Brand personality/tone: How should the interface feel?
Check the Architecture Plan from Phase 7 (locate it within .jonggrang/.output/features/ using your search tools) or AGENTS.md for this context. If not present, infer it from existing codebase files (like DESIGN.md or a global theme file).
Design Direction
Commit to a BOLD aesthetic direction:
- Purpose: What problem does this interface solve?
- Tone: Pick an extreme: brutally minimal, maximalist chaos, retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian.
- Constraints: Technical requirements (framework, performance, accessibility).
- Differentiation: What makes this UNFORGETTABLE?
CRITICAL: Choose a clear conceptual direction and execute it with precision. Bold maximalism and refined minimalism both work—the key is intentionality, not intensity.
Frontend Aesthetics Guidelines (Flattened References)
1. Typography
Choose fonts that are beautiful, unique, and interesting. Pair a distinctive display font with a refined body font.
- DO: Use a modular type scale with fluid sizing (clamp).
- DO: Vary font weights and sizes to create clear visual hierarchy.
- DON'T: Use overused fonts (Inter, Roboto, Arial, Open Sans, system defaults).
- DON'T: Put large icons with rounded corners above every heading.
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.

implementing-frontend-design is a skill published in the GitHub repository porcupine-md/jonggrang (11 stars, last pushed today), licensed MIT. It adds 51 tokens to every session and 1,308 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
