Paper Analyst

Analyze academic papers from PDF or pasted text. Output in Chinese by default. All outputs follow references/output-schema.md. Paper type detection uses references/paper-type-rubric.md. Anti-hallucination rules in references/quality-checklist.md.

Quick Reference

Mode Selection

Default mode: standard. Detect from user's request:

Mode	Trigger	Output
quick	"quick", "简单说", "一句话", "简要"	Header + info + abstract + 3 contributions
standard	(default)	Full analysis: sections 1–5
extended	"前作", "课题组", "prior work"	standard + author/group prior work
presentation	"PPT", "组会", "汇报大纲", "slides"	standard + slide outline
presentation_with_figures	"图表", "figures", "带图", "关键图"	presentation + figure annotations

If ambiguous, use standard and offer to switch.

Workflow

Step 1: Assess Input Quality

Classify PDF quality before analysis:

• 良好: Full text extractable
• 降级处理: Partial text, scanned sections, garbled encoding
• 严重降级: Minimal text, image-only PDF

If degraded: state reason in header line, proceed with available content, mark all gaps explicitly. Never fabricate content to fill gaps.

Optional: if user has Python, suggest running scripts/extract_pdf_meta.py first for structured metadata.

Step 2: Classify Paper Type

Read references/paper-type-rubric.md and classify. Do NOT assume AI/ML. Output the type label and 2–3 evidence indicators before proceeding.

Step 3: Execute Analysis

Follow references/output-schema.md for the selected mode. Apply all rules from references/quality-checklist.md throughout every section.

Step 4: Self-Check Before Output

Verify before finalizing:

• Every uncertain field marked [不确定] or [未明确给出]
• Every contribution tagged [原文声明] or [模型归纳]
• No section silently omitted — skipped sections state why
• Paper type label matches rubric evidence

Anti-Hallucination Rules

Full rules in references/quality-checklist.md. Non-negotiable constraints:

1. Source tagging: [原文声明] = directly stated in paper (cite location); [模型归纳] = inferred by model (state reasoning basis)
2. Uncertainty: [未明确给出] when absent; [不确定] when ambiguous
3. No domain assumption: classify paper type first, always
4. No fabrication: venue, DOI, year, affiliations not in text → [未明确给出]
5. Evidence binding: each contribution must cite section/figure/table/quote
6. Degraded PDF: state which sections were unreadable; do not fill gaps

Degraded Input Fallback

Situation	Action
Only abstract available	quick mode, note limitation
Scanned PDF, no text	Ask user for text or OCR first
Missing references section	Skip prior work analysis, note absence
Figures unreadable	Skip figure analysis, note absence
Non-English paper	Translate key sections, note source language

Extended Mode: Author Prior Work

Only in extended mode:

1. Extract all author names from paper
2. Identify self-citations in reference list (shared authors)
3. Infer research group focus from affiliations + paper title
4. List prior works from reference list only — no web search, no external knowledge
5. Tag all output: [基于论文内引用，非外部检索]
6. If insufficient info: explicitly state "信息不足，无法判断前作关系"

Presentation Mode: PPT Generation

Only in presentation or presentation_with_figures mode.

Step A: Collect Overrides

Before building the slide plan, check if the user specified any of:

• audience (lab / conference / general) — default: lab
• duration_hint (10min / 20min / 30min) — default: 20min
• talk_style (technical / overview / discussion) — default: technical
• emphasis (which sections to expand)
• skip (which sections to omit)

If not specified, use defaults silently.

Step B0: Extract PDF Figures (presentation_with_figures only)

Before building the slide plan, run:

python scripts/extract_pdf_figures.py <pdf_path>

This saves all figures to figures/ and writes figures/index.json with name, path, and page for each image. Use this index when assigning figure_ref paths in the handoff.

Step B: Build Slide Plan

Follow references/presentation-schema.md for structure. Follow references/presentation-style-guide.md for compression rules.

• Map each slide role to the corresponding output-schema section
• Apply user overrides (emphasis → expand, skip → omit)
• For presentation_with_figures: set figure_needed: true on method/result slides where a figure is the primary evidence; add figure_ref and figure_hint
• Slide count from duration_hint (10min→6-7, 20min→9-10, 30min→12-14)

Step C: Call pptx Skill

Follow references/pptx-handoff.md for the exact handoff format.

• Strip all [原文声明] / [模型归纳] tags before passing to pptx
• Do NOT include speaker notes in the handoff
• Call pptx skill automatically — do not ask the user first
• Exception: if user said "只要大纲" / "just the outline", output the slide plan as text and skip pptx
