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

  1. mineru skill。
  2. 宿主 pdf skill。
  3. pdfplumber 文本和表格提取。
  4. 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

agent-research-aggregator

Free

Pre-pipeline aggregator that scans AI agent cache directories (.claude, .cursor, .antigravity, .openclaw) or any user-specified directory for experimentation logs, extracts insights and numeric results, and formats them as PaperOrchestra-ready inputs (idea.md + experimental_log.md). TRIGGER when the user says "aggregate my agent logs for paper writing", "extract experiments from my coding agent history", "prepare PaperOrchestra inputs from my cache", "turn my agent logs into a paper", mentions a folder or directory they want to use as the basis for a paper, or wants to run PaperOrchestra but only has scattered agent experiment histories rather than structured inputs. Run this BEFORE paper-orchestra. Also called automatically by paper-orchestra when workspace/inputs/idea.md or workspace/inputs/experimental_log.md are missing.

brainstorming

Free

Use when EZ_math_model model selection is unclear after the modeling decision tree, the problem spans multiple domains, or modeler needs several candidate approaches before writing modeling_plan.md.

content-refinement-agent

Free

Step 5 of the PaperOrchestra pipeline (arXiv:2604.05018). Iteratively refine drafts/paper.tex by simulating peer review and applying targeted revisions, with strict accept/revert halt rules. Maintains a worklog and snapshots each iteration so revert is real, not symbolic. TRIGGER when the orchestrator delegates Step 5 or when the user asks to "refine the draft", "iterate on the paper", or "run peer review on this paper".
