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 | $0.10231 | $0.10231 |
| Opus 5.5 | $0.04092 | $0.04092 |
| Sonnet 5.5 | $0.02046 | $0.02046 |
| Haiku 4.5 | $0.01023 | $0.01023 |
Grade A, and why
ChuMaiNichi AGENTS.md 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 yesterday.
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.

What is this project?
ChuMaiNichi (Chunithm + maimai + 毎日/mainichi = "playing daily") is a personal dashboard for CHUNITHM and maimai DX arcade rhythm game players. It tracks daily play counts, ratings over time, and uses an AI agent to suggest songs for efficient rating improvement.
This repo merges two previous repos:
Phudit-2547/Chunimai-tracker(Python Playwright scraper, 63 commits — code lives inscraper/)Phudit-2547/Chunimai_dashboard(old Bun/Elysia dashboard — fully replaced, no code carried over)

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.
