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 | $0.00125 | $0.01475 |
| Opus 5.5 | $0.00050 | $0.00590 |
| Sonnet 5.5 | $0.00025 | $0.00295 |
| Haiku 4.5 | $0.00013 | $0.00147 |
Grade A, and why
methodology 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 14d 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

[!WARNING] Experimental Feature / 實驗性功能
This feature is under active development and may change significantly in v4.0. 此功能正在積極開發中，可能在 v4.0 中有重大變更。
Select and manage the active development methodology for the current project. This skill focuses on choosing which methodology to use (SDD, BDD, TDD) and tracking phase progress within the chosen methodology.
選擇並管理當前專案的開發方法論。此技能專注於選擇使用哪種方法論（SDD、BDD、TDD）並追蹤所選方法論內的階段進度。

What ships with it
5 files 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.
- 14d ago First seen · 116 lines · 125 tokens per session scan A 1b3dc1063a5c
methodology is a skill published in the GitHub repository AsiaOstrich/EngramGraph (3 stars, last pushed today), licensed MIT. It adds 125 tokens to every session and 1,475 once invoked, about $0.0005 per session on Opus 5.5. 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 2026-10-16.
