description: Build full-paper Chinese-English side-by-side, figure/table-aware, source-grounded Markdown readers for journal or conference papers from PDF, DOI, arXiv, publisher HTML, or pasted text. Use whenever the user asks to translate or read a paper, make 中英文对照/原文对照/全文翻译解读, extract figures or tables into the right positions, preserve figure/table placement near relevant prose, or keep exact source anchors for every block. This skill must not degrade into a summary-only output unless the user explicitly asks for a summary.

Full-Paper Markdown Reader

Use this skill to turn a research paper into a complete Markdown reading artifact.

The default output should read like a bilingual paper companion, not a summary dump:

• keep the extractable prose, paragraph structure, and section flow
• show original text and Chinese translation together at block level
• extract figures and tables as assets and place them at the first substantive mention or interpretation point
• keep captions attached to figures/tables with English caption text and Chinese caption translation
• preserve stable page and block anchors for traceability
• write a complete `paper.md` by default, plus `source_map.json`, `translation_notes.md`, and `assets/`

This skill is for papers, preprints, and conference proceedings across disciplines. It is not limited to Nature-family journals.

When to use

Use this skill when the user wants any of the following:

• translate an entire paper into a complete Markdown document
• make a paper easier to read without losing the original wording
• generate a full-paper reading file with original/translation alignment
• keep figures or tables visually close to the claims they support
• preserve exact source locations for every substantive block
• build a source-grounded markdown artifact rather than a slide deck or short summary

If the user only wants a summary, use a summarization skill instead. If the user only wants citation search, use a citation skill instead.

Non-negotiable defaults

When the user asks for paper translation, reading, `nature-reader`, `中英文对照`, `原文对照`, `全文翻译`, or `翻译解读`, produce a paragraph-level bilingual reader by default.

Do not replace the reader with:

• a Chinese-only summary
• a paper review without original/translation alignment
• figure captions without figure/table crops
• a list of key points detached from source locations
• only the abstract, introduction, or selected highlights

If constraints prevent full processing, still create a draft reader and clearly label missing pages, missing figures/tables, untranslated blocks, or low-confidence OCR/crops in `translation_notes.md`.

Core principle

Translate for meaning, not for style. Preserve the paper's structure, evidence, hedging, terminology, equations, units, and citation markers. Keep the output in prose paragraphs unless the source itself is tabular or list-like. Do not collapse the paper into keyword bullets or slide-style notes.

The reading file should help a reader move between:

• original text
• translated text
• source location
• figure or table evidence

Each substantive source block should have a stable anchor and a visible bilingual pair:

<a id="S001"></a>
**Source:** p.1 S001

**Original:** [source paragraph]

**中文:** [faithful Chinese translation]

For copyrighted publisher PDFs, keep chat responses short and point to the local artifact. In local `paper.md`, include the bilingual reader only for the user-provided source file or clearly lawful open-access content; avoid reproducing large copyrighted text directly in chat.

Workflow

1. Identify the source and paper type

Determine whether the source is:

• selectable-text PDF
• scanned PDF
• publisher HTML
• DOI or arXiv link
• pasted text or notes

Then identify the paper type at a high level:

• discovery or mechanism paper
• methods or algorithm paper
• resource or dataset paper
• conference paper
• review or perspective

This helps decide how tightly to couple text, figures, and captions.

2. Build a full-document source map before translating

If the user provides a full paper, process the entire document. Do not stop at the abstract, introduction, or a few representative pages unless the user explicitly asks for a preview.

Create stable IDs for source blocks:

• `S001`, `S002`, ... for body text
• `C001`, `C002`, ... for captions
• `F001`, `F002`, ... for figures
• `T001`, `T002`, ... for tables

For each block, capture:

• page number
• block type
• original text
• translation
• reading-order index
• nearby figure or table references
• first substantive figure/table mention when applicable
• confidence level when extraction is uncertain

Keep the source map stable so later questions can point back to the same IDs. For long papers, add a page index so the reader can jump across the whole document without losing location.

3. Translate conservatively

Translate every extractable substantive block with these rules:

• preserve technical terms unless a standard Chinese equivalent is clearly better
• keep gene names, protein names, formulas, model names, and symbols intact
• keep citations, superscripts, subscripts, and numeric values unchanged
• do not collapse methods details into vague prose
• keep paragraph order and section order unless the user asks for restructuring
• mark uncertain text instead of guessing when OCR or layout extraction is weak
• keep the source's paragraph form; do not convert dense prose into bullet-point keywords
• do not silently skip Methods, limitations, data availability, code availability, competing interests, or extended captions
• if the paper is too long for one pass, write `paper.md` incrementally by page/section and mark pending blocks rather than switching to summary mode

If a sentence contains multiple claims, keep the translation readable but do not split away the original evidence chain.
