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 | $0.00000 | $0.04579 |
| Opus 5.5 | $0.00000 | $0.01832 |
| Sonnet 5.5 | $0.00000 | $0.00916 |
| Haiku 4.5 | $0.00000 | $0.00458 |
Grade C, and why
knowledge-base scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
rm -rf "$TEMP_DIR" Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
CONTENT_TYPE=$(curl -sI -L "<url>" | grep -i "^content-type:" | tail -1 | awk '{print $2}' | tr -d '\r') This is a copy
100% identical to knowledge-base — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 384 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Knowledge Base (知识库)
API base path: openapi/wiki/v1 — 完整数据结构和接口参数详见 references/api.md。
接口决策表
| 用户意图 | 调用接口 | 关键参数 |
|---|---|---|
| 上传文件到知识库 | check_repeated_names → create_media → COS Upload → add_knowledge |
media_type（按扩展名），knowledge_base_id，file_name，file_size |
| 上传文件到知识库的某个文件夹 | 先定位文件夹 → 同上（folder_id 传入目标文件夹 ID） |
见「文件夹操作」章节 |
| 添加网页/微信文章到知识库 | import_urls |
urls（1-10 个），knowledge_base_id，可选 folder_id（省略则根目录） |
| 添加笔记到知识库 | add_knowledge |
media_type=11，note_info.content_id=<note_id>，knowledge_base_id |
| 添加 URL（文件型）到知识库 | check_repeated_names → 下载文件 → 走"上传文件"流程 |
URL 指向 PDF/Word/PPT 等文件时，按文件方式处理 |
| 检查文件名是否重复 | check_repeated_names |
params[].name，params[].media_type，knowledge_base_id，folder_id |
| 获取知识库信息 | get_knowledge_base |
ids（1-20 个，不重复） |
| 浏览知识库内容列表 / 浏览文件夹 | get_knowledge_list |
knowledge_base_id，cursor，limit(1~50)，可选 folder_id |
| 在知识库中搜索（含文件和文件夹） | search_knowledge |
query，knowledge_base_id，cursor |
| 按关键词查找知识库（用户知道名字但不知道 ID） | search_knowledge_base |
query，cursor，limit(1~20) |
| 查看/了解自己有哪些知识库 | search_knowledge_base（query 传空字符串） |
query: ""，cursor，limit(1~20) |
| 添加内容但未指定目标知识库 | get_addable_knowledge_base_list → 展示列表让用户选择 |
cursor，limit(1~50) |
| 查看原文、分析原文、导出原文 | get_media_info |
media_id；导出/下载时在 URL 后追加 response-content-type + response-content-disposition 参数 |
What ships with it
3 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.

knowledge-base is a skill published in the GitHub repository HK-hub/AgentSkills (6 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 4,579 tokens. A static security scan graded it C with 2 findings (recursive force delete, makes network calls). It is 100% identical to knowledge-base, differing in 0 lines, and is treated as a copy.
