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 | $0.00020 | $0.00290 |
| Opus 5 | $0.00010 | $0.00145 |
| Sonnet 5 | $0.00004 | $0.00058 |
| Haiku 4.5 | $0.00002 | $0.00029 |
Grade A, and why
pdf-case-converter 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 4d 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
PDF Case Converter Skill
Description
这是一个用于处理 PDF 文件的工具，专门用于将 PDF 中的文本内容转换为小写。它通过调用本地的 Python 脚本来完成转换。
Instructions
当用户请求将某个 PDF 文件的内容转换为小写时，请遵循以下步骤：
- 检查文件路径：确认用户提供的输入文件路径存在。
- 构建输出路径：如果用户没有指定输出路径，默认在原文件名后加上
_lower后缀（例如input.pdf->input_lower.pdf）。 - 执行脚本：
在当前文件所在的目录下，使用
Bash工具运行以下命令：python3 scripts/pdf_lowercase.py <输入文件路径> <输出文件路径> - 验证结果：脚本执行完成后，检查输出文件是否生成成功，并向用户报告结果。
Examples
User: "把 document.pdf 里的字都变成小写。"
Assistant: (Executing Bash from this file's directory) python3 scripts/pdf_lowercase.py document.pdf document_lower.pdf
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.

pdf-case-converter is a skill published in the GitHub repository wangwei1237/agent-skills (4 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 20 tokens to every session and 290 once invoked, about $0.0001 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.
