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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00037 | $0.00514 |
| Opus 5 | $0.00018 | $0.00257 |
| Sonnet 5 | $0.00007 | $0.00103 |
| Haiku 4.5 | $0.00004 | $0.00051 |
Grade A, and why
pdf 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 5d 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 — PDF 读取与转换兜底
何时使用
- 用户上传
.pdf题目。 - 需要读取优秀论文 PDF 的摘要、目录或局部章节。
- MinerU 不可用或输出失败。
- PDF 扫描件需要 OCR。
优先链路
mineruskill。- 宿主
pdfskill。 pdfplumber文本和表格提取。- 图像 OCR 兜底。
论文 PDF 导出兜底
scripts/runtime/export_paper.ps1 的 simple text-only PDF 只用于占位交付。该兜底
使用基础字体，非 ASCII 字符会被替换为 ?，因此中文 formal 论文不能把它视为
高保真 PDF。出现该兜底时必须：
- 在
export_report.json中写pdf_fallback与paper_pdf_high_fidelity=false； - 在
export_audit.json中标记pdf_readability=placeholder或 warning； - 最终质量等级最高为
provisional_pass。
题目 PDF 转 Markdown
import pdfplumber
with pdfplumber.open("problem.pdf") as pdf:
text = "\n\n".join(page.extract_text() or "" for page in pdf.pages)
with open("problem.md", "w", encoding="utf-8") as f:
f.write(text)
复杂表格、公式和多栏排版优先交给 mineru。
参考论文读取策略
- 优先读标题、摘要、目录、参考文献。
- 只在需要借鉴模型表述时读对应章节。
- 每篇累计读取页数不超过 5 页。
- 不全文复制优秀论文内容。
失败诊断
| 情况 | 处理 |
|---|---|
| 全部 PDF 工具不可用 | 保留原 PDF，让多模态能力直接读 |
| 提取乱码 | 写诊断，建议用户提供文本版 |
| 公式提取失败 | 保留原始字符串，由 writer 补 LaTeX |
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 is a skill published in the GitHub repository woodfishhhh/EZ_math_model (40 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 514 once invoked, about $0.0002 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.
