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 | $0.00069 | $0.01238 |
| Opus 5.5 | $0.00028 | $0.00495 |
| Sonnet 5.5 | $0.00014 | $0.00248 |
| Haiku 4.5 | $0.00007 | $0.00124 |
Grade A, and why
security 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

Security Review Workflow | 安全審查工作流程
SCOPE ──► SCAN ──► ANALYZE ──► REPORT
1. Scope — Define Audit Boundary | 定義審計範圍
Identify target modules, data flows, and trust boundaries.
識別目標模組、資料流和信任邊界。
2. Scan — Identify Vulnerabilities | 識別漏洞
Review code for OWASP Top 10 patterns, check dependencies, inspect configurations.
檢查程式碼的 OWASP Top 10 模式、檢查相依套件、檢視配置。
3. Analyze — Assess Risk | 評估風險
Classify findings by severity (Critical/High/Medium/Low) and exploitability.
依嚴重程度（Critical/High/Medium/Low）和可利用性分類。
4. Report — Document Findings | 記錄發現
Produce actionable findings with remediation recommendations.
產出可行動的發現報告，附帶修復建議。
Severity Classification | 嚴重程度分類
| Level | Criteria | 標準 |
|---|---|---|
| Critical | Remote code execution, data breach | 遠端程式碼執行、資料洩漏 |
| High | Authentication bypass, privilege escalation | 認證繞過、權限提升 |
| Medium | Information disclosure, CSRF | 資訊洩漏、CSRF |
| Low | Missing headers, verbose errors | 缺少 Header、冗長錯誤訊息 |
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 · 107 lines · 69 tokens per session scan A f8b870e114fb
security is a skill published in the GitHub repository AsiaOstrich/EngramGraph (3 stars, last pushed today), licensed MIT. It adds 69 tokens to every session and 1,238 once invoked, about $0.0003 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.
