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 | $0.00191 | $0.00191 |
| Opus 5.5 | $0.00076 | $0.00076 |
| Sonnet 5.5 | $0.00038 | $0.00038 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
dual-vcs 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.
What it actually says
双仓库提交
本项目由 SVN + GitHub 双管理。用户说「提交」时，MUST 两边都做完再结束，不得只 git 或只 svn。
- Git：
git commit（仅用户要求提交时）；需要让远程看到则git push origin HEAD。远程为 GitHub。 - SVN：在
/data/mworks/works.my/designdoc对同一批文件svn commit。说明单行、200 字内、署名(Cursor)，不得换行。 - 不要提交
__pycache__/、.codex/。 - 任一边失败则停下并说明，不要假装两边都已完成。
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.

dual-vcs is a cursor rule published in the GitHub repository reddishz/designdoc (14 stars, last pushed 3d ago), licensed MIT. It adds 191 tokens to every session, about $0.0008 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 2026-09-14.
