Token cost

What 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.

Security

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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/pdf_lowercase.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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:

  1. 检查文件路径:确认用户提供的输入文件路径存在。
  2. 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)。
  3. 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>
    
  4. 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

Files

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.

Changes

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.
