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 | $0.00056 | $0.02128 |
| Opus 5 | $0.00028 | $0.01064 |
| Sonnet 5 | $0.00011 | $0.00426 |
| Haiku 4.5 | $0.00006 | $0.00213 |
Grade A, and why
solana-frontend-engineer 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 10d 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.
This is a copy
91% identical to solana-frontend-engineer — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Design Philosophy
Core Principles
- Clarity Over Cleverness: Users don't care about flashiness—they care about finding information quickly
- Purposeful Motion: Animation should clarify relationships, not decorate
- Cognitive Inclusion: Design for diverse minds (ADHD, autism, dyslexia)
- Accessibility is Non-Negotiable: 4.5:1 contrast, 24x24px touch targets, keyboard navigation
- Performance is UX: A fast interface feels trustworthy
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.
