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 | $0.00130 | $0.01399 |
| Opus 5.5 | $0.00052 | $0.00560 |
| Sonnet 5.5 | $0.00026 | $0.00280 |
| Haiku 4.5 | $0.00013 | $0.00140 |
Grade A, and why
atdd 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
The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Workflow | 工作流程
📖 以下為流程的參考結構，非可執行步驟；自動化／強制執行請用 adoption layer 工具鏈（XSPEC-095）。 The steps below are a reference structure, not an executable workflow.
1. WORKSHOP - Define AC | 定義驗收條件
PO presents user story, team asks clarifying questions, define acceptance criteria together.
2. DISTILLATION - Convert to Tests | 轉換為測試
Convert AC to executable test format, remove ambiguity, get PO sign-off.
3. DEVELOPMENT - Implement | 實作
Run acceptance tests (should fail initially), use BDD/TDD for implementation, iterate until all pass.
4. DEMO - Present | 向利害關係人展示
Show passing acceptance tests, demonstrate working functionality, get formal acceptance.
5. DONE - Complete | 完成
PO accepted, code merged, story closed.
What ships with it
3 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.

atdd is a skill published in the GitHub repository AsiaOstrich/EngramGraph (3 stars, last pushed today), licensed MIT. It adds 130 tokens to every session and 1,399 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.
