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.
npx agentmods add rules/yoruto/prd-kit/00-prd-kitgit clone --depth 1 https://github.com/Yoruto/prd-kitWhat it costs to keep this loaded
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 | $0.00349 | $0.00349 |
| Opus 5 | $0.00175 | $0.00175 |
| Sonnet 5 | $0.00070 | $0.00070 |
| Haiku 4.5 | $0.00035 | $0.00035 |
Grade A, and why
00-prd-kit 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 2d 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
PRD 工具包 - 总规则（极简）
工作流
- 实现范围以 PRD 为准。默认 PRD 路径见 项目内
config/PROJECT.md（未单独拆分时，约定为docs/prd/active/*.md，完成后可移至docs/prd/archive/；模板见本工具包templates/prd/feature-template.md或你仓库中的docs/prd/templates/）。 - 在 Cursor Composer 中：先 @ 当前 PRD 文件，再 @
prd-workflow.mdc与本文件。若项目已启用 Stack Profile（从examples/<stack>/复制到.cursor/rules/的架构/命名规范），一并 @ 对应 mdc。 - 分层、步骤、禁止空补业务、报告格式等见
prd-workflow.mdc，不在此重复。
验证
- 有代码改动时，执行
config/PROJECT.md中列出的验证命令；未写则先补全该文件再提交流程。
安全
- 不在聊天或已跟踪文件中写入真实密钥；环境变量名仅使用仓库内
.env.example（或项目文档）中已列出的名称。
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.

00-prd-kit is a cursor rule published in the GitHub repository Yoruto/prd-kit (2 stars, last pushed 4mo ago), licensed MIT. It adds 349 tokens to every session, about $0.0017 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.
