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 | $0.00118 | $0.03767 |
| Opus 5 | $0.00059 | $0.01884 |
| Sonnet 5 | $0.00024 | $0.00753 |
| Haiku 4.5 | $0.00012 | $0.00377 |
Grade A, and why
nexus-mapper 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 8d 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.

nexus-mapper — AI 项目探测协议
本 Skill 指导 AI Agent 使用 PROBE 五阶段协议，对任意本地 Git 仓库执行系统性探测，产出 .nexus-map/ 分层知识库。
何时调用 / 何时不调用
| 场景 | 调用 |
|---|---|
| 用户提供本地 repo 路径，希望 AI 理解其架构 | 是 |
需要生成 .nexus-map/INDEX.md 供后续 AI 会话冷启动 |
是 |
| 用户说「帮我分析项目」「建立项目知识库」「让 AI 了解这个仓库」 | 是 |
运行环境无 shell 执行能力（纯 API 调用模式，无 run_command 工具） |
否 |
| 宿主机无本地 Python 3.10+ | 否 |
目标仓库无任何已知语言源文件（.py/.ts/.java/.go/.rs/.cpp 等均无） |
否 |
用户只想查询某个特定文件/函数 → 直接用 view_file / grep_search |
否 |
前提检查
缺失项要显式告知用户；需要降级等时及时提醒用户，经过同意才能继续。
| 前提 | 检查方式 |
|---|---|
| 目标路径存在 | $repo_path 可访问 |
| Python 3.10+ | python --version >= 3.10 |
| 脚本依赖已安装 | python -c "import tree_sitter" 无报错 |
| 有 shell 执行能力 | Agent 环境支持 run_command 工具调用 |
git 历史是加分项，不是硬阻塞项。没有 .git 或历史过少时，跳过热点分析，并在输出中明确记录这是一次降级探测。
输入契约
repo_path: 目标仓库的本地绝对路径（必填）
语言支持：自动按文件扩展名 dispatch，语言配置（扩展名映射 + Tree-sitter 查询）存储在 scripts/languages.json。当前已接入 Python/JavaScript/TypeScript/TSX/Bash/Java/Go/Rust/C#/C/C++/Kotlin/Ruby/Swift/Scala/PHP/Lua/Elixir/GDScript/Dart/Haskell/Clojure/SQL/Proto/Solidity/Vue/Svelte/R/Perl 等 30+ 语言。
非标准语言：若仓库含有内置未支持的语言，通过命令行参数动态补充（详见 references/language-customization.md）：
--add-extension .templ=templ添加新文件扩展名映射--add-query templ struct "(component_declaration ...)"添加结构查询--language-config <JSON_FILE>复杂配置时使用 JSON 文件
输出格式
执行完成后，目标仓库根目录下将产出：

What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

nexus-mapper is a skill published in the GitHub repository Haaaiawd/ANWS (142 stars, last pushed 3mo ago), licensed MIT. It adds 118 tokens to every session and 3,767 once invoked, about $0.0006 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.
