What it costs to keep this loaded
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 | $0.00079 | $0.01376 |
| Opus 5.5 | $0.00032 | $0.00550 |
| Sonnet 5.5 | $0.00016 | $0.00275 |
| Haiku 4.5 | $0.00008 | $0.00138 |
Grade A, and why
gmail 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 1mo 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.

- 어떤 계정을 써야 할지 파악할 수 없으면 AskUserQuestion으로 사용자에게 어떤 계정을 사용할지 물어본다.
3. 요청 분류 및 실행
사용자 요청을 아래 중 하나로 분류하여 실행한다.

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 1mo ago First seen · 175 lines · 79 tokens per session scan A d3ef7fec98d1
gmail is a skill published in the GitHub repository greatSumini/cc-system (438 stars, last pushed 4mo ago), licensed MIT. It adds 79 tokens to every session and 1,376 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings.
