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 instructions/librespark/libredomains/claude-mdgit clone --depth 1 https://github.com/LibreSpark/LibreDomainsWhat 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 | $0.03151 | $0.03151 |
| Opus 5 | $0.01576 | $0.01576 |
| Sonnet 5 | $0.00630 | $0.00630 |
| Haiku 4.5 | $0.00315 | $0.00315 |
Grade A, and why
LibreDomains CLAUDE.md 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 3d 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 — 388 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LibreDomains - AI 项目上下文
本文档专为 AI 助手提供项目技术上下文，包含架构、工作流程、API 参考等技术细节。
项目概述
LibreDomains 是一个基于 GitHub 的二级域名分发服务，用户通过提交 Pull Request 申请和管理域名。

分层架构
- 配置存储层：GitHub 仓库存储所有域名配置（JSON 格式）
- 验证层：Python 脚本 + GitHub Actions 自动验证
- 部署层：Python 脚本通过 Cloudflare API 部署 DNS 记录
- 监控层：定期健康检查确保域名正常工作
关键依赖
-
第三方服务商：
- Cloudflare（DNS 解析）
- GitHub（代码托管、CI/CD）
-
外部 API：
- Cloudflare API（DNS 管理）
- GitHub API（PR 评论）

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.
- 3d ago First seen · 388 lines · 3,151 tokens per session scan A 9e64d37c2833
LibreDomains CLAUDE.md is an instructions file published in the GitHub repository LibreSpark/LibreDomains (102 stars, last pushed 9mo ago), licensed MIT. It adds 3,151 tokens to every session, about $0.0158 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 2026-08-30.
