Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00056 | $0.00421 |
| Opus 5 | $0.00028 | $0.00211 |
| Sonnet 5 | $0.00011 | $0.00084 |
| Haiku 4.5 | $0.00006 | $0.00042 |
Grade A, and why
prompt-portability 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 11d 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.

目標
把規則轉成目標平台真正能執行的版本，刪除平台不支援的本機操作要求，保留思考品質與交付品質。
流程
- 確認目標平台：Gemini 網頁版、Claude 網頁版、ChatGPT、API、Codex、Claude Code。
- 判斷平台能力：是否可讀寫檔案、是否可用工具、是否可執行程式、是否可上網、是否支援自訂指令。
- 保留跨平台原則：繁中、先理解、列假設、低成本優先、少做多餘功能、查證、結論清楚。
- 刪除或降級不適用規則：本機檔案修改、Git、
.env、同步腳本、工作區路徑、工具權限。 - 壓縮成適合目標欄位的長度；必要時提供完整版與短版。

判斷原則
- 網頁版 AI：偏向行為指引，不寫本機執行規則。
- Codex / Claude Code：可保留檔案、測試、同步、工具與權限規則。
- API Agent：保留輸入/輸出契約、工具邊界、錯誤處理與驗證。
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.
- 11d ago First seen · 35 lines · 56 tokens per session scan A 83fcd2682b8a
prompt-portability is a skill published in the GitHub repository a275618631/codex-antigravity-collaboration (8 stars, last pushed yesterday), licensed MIT. It adds 56 tokens to every session and 421 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
