Literature Survey Generator

A multi-agent, multi-phase pipeline that produces a complete academic literature survey in LaTeX with BibTeX — from search to final compiled PDF.

When to Use

• User wants a literature review on a topic across specific journals
• User wants to find and synthesize recent papers in a field
• User asks for a survey of Top 5 / Top Field journals on a topic
• User wants automated paper search → download → review writing

Overview

The pipeline has 4 phases, each using parallel subagents where possible:

Phase 1: SEARCH (parallel per journal)
    ↓ search_{journal}.json files
Phase 2: PROCESS (3 parallel agents)
    ↓ references.bib + paper_summaries.md + pdfs/
Phase 3: DRAFT (1 agent + compilation)
    ↓ survey.tex → survey.pdf
Phase 4: REVIEW & REVISE (sequential)
    ↓ review_report.md → survey_v2.tex → survey_v2.pdf

Execution Instructions

Step 0: Setup

1. Parse the user's request to extract:

   • Topic: The search query (e.g., "networks", "behavioral economics")
   • Journals: Which journals to search (default: Top 5 Economics)
   • Year range: Publication year(s) (default: current year)
   • Output format: LaTeX (default), Markdown, or both

2. Create working directory:

   agent_tasks/{topic_slug}_{YYYYMMDDHH}/
   

3. Write plan.md to the working directory documenting the execution plan.

4. Set up task tracking with TaskCreate for the 4 phases.

Step 1: Phase 1 — Parallel Journal Search

Launch one subagent per journal (up to 10 in parallel). Each agent:

1. Queries OpenAlex API with the journal's source ID and topic keyword
2. Queries CrossRef API with the journal's ISSN and topic keyword
3. Deduplicates results by DOI
4. Saves to search_{journal_abbrev}.json

Agent prompt template:

Search for papers about "{TOPIC}" published in {JOURNAL_NAME} in {YEAR}.

1. OpenAlex API (source ID: {OPENALEX_ID}):
   curl -s "https://api.openalex.org/works?filter=primary_location.source.id:{OPENALEX_ID},default.search:{TOPIC},publication_year:{YEAR}&per_page=50&mailto=xueheng@mail.sysu.edu.cn"

2. CrossRef API (ISSN: {ISSN}):
   curl -s "https://api.crossref.org/journals/{ISSN}/works?query={TOPIC}&filter=from-pub-date:{YEAR}-01-01&rows=50&mailto=xueheng@mail.sysu.edu.cn"

Extract: title, authors, doi, year, cited_by, pdf_urls, abstract (from inverted index), openalex_id.
Deduplicate by DOI. Save to: {WORKDIR}/search_{ABBREV}.json

Key journal identifiers (verify OpenAlex IDs via API before use):

Journal	ISSN	OpenAlex ID
American Economic Review	0002-8282	S23254222
Econometrica	0012-9682	S95464858
Journal of Political Economy	0022-3808	(verify via API)
Quarterly Journal of Economics	0033-5533	S203860005
Review of Economic Studies	0034-6527	(verify via API)

For non-Top-5 journals, first look up the OpenAlex source ID:

curl -s "https://api.openalex.org/sources?search={journal+name}&mailto=xueheng@mail.sysu.edu.cn"

Wait for all search agents to complete before proceeding.

After all agents complete, do a quick tally: read each search_*.json and count papers. If total < 3, consider broadening the search terms or year range. If total > 30, the topic may need narrowing — flag this to the user.

Step 2: Phase 2 — Process (3 Parallel Agents)

Launch these 3 agents simultaneously:

Agent A: PDF Downloader

For each paper with a DOI:

1. Query Unpaywall: https://api.unpaywall.org/v2/{DOI}?email=xueheng@mail.sysu.edu.cn
2. Check best_oa_location.url_for_pdf and all oa_locations[].url_for_pdf
3. If PDF URL found, download to pdfs/{safe_filename}.pdf
4. Verify each download is a real PDF (file > 10KB, starts with %PDF)
5. Save pdfs/download_report.md

Agent B: BibTeX Builder

For each DOI:

curl -sL -H "Accept: application/x-bibtex" "https://doi.org/{DOI}"

• Clean citation keys to {firstauthor}{year}{keyword} format
• Add foundational references cited in the introduction (if known)
• Save to references.bib

Agent C: Summary Extractor

For each paper:

1. Read abstracts from search_*.json files
2. For missing/truncated abstracts, query OpenAlex for full inverted abstract
3. As fallback, query Semantic Scholar (with 3s sleep between calls)
4. Save paper_summaries.md with per-paper sections:
   • Title, Authors, Journal, DOI, Citations, Full Abstract, Key Themes
5. Save all_papers.json (consolidated, enriched metadata)

Wait for all 3 agents to complete before proceeding.

Step 3: Phase 3 — Draft LaTeX Survey

Launch 1 agent to write the survey. The agent reads:

• paper_summaries.md (content source)
• references.bib (citation keys)

Survey structure (adapt based on paper count and topics):

\documentclass[12pt]{article}
\usepackage{amsmath,amssymb,natbib,geometry,hyperref,booktabs,setspace,array}
\bibliographystyle{plainnat}

1. Title, Author, Abstract (150-200 words)
2. Introduction
   - Motivation for the topic
   - Selection methodology (how papers were found)
   - Brief overview of themes
   - Positioning relative to existing surveys
3. Summary Table (booktabs: Authors, Journal, Title, Type, Key Aspect)
4-6. Thematic Sections (group papers by theme, not by journal)
   - Each paper: 2+ paragraphs of substantive discussion
   - Critical engagement: limitations, open questions
   - Cross-references between papers where relevant
7. Methodological Advances (compare approaches across papers)
8. Conclusion (synthesis, gaps, future directions)

Important instructions for the drafting agent:

• Use \citet{} for in-text citations, \citep{} for parenthetical
• Be transparent about papers with tangential relevance to the topic
• Add critical engagement (limitations, open questions) for at least 3 papers
• Verify all \cite keys match entries in references.bib
• Target 8-15 pages when compiled

After the agent saves survey.tex, compile it:

cd {WORKDIR}
pdflatex -interaction=nonstopmode survey.tex
bibtex survey
pdflatex -interaction=nonstopmode survey.tex
pdflatex -interaction=nonstopmode survey.tex

Check for errors. Fix any compilation issues before proceeding.

Step 4: Phase 4 — Review & Revise

4a: Review Agent

Reads survey.tex, paper_summaries.md, references.bib. Writes review_report.md covering:

1. Content Accuracy: Does each paper description match its abstract?
2. Structure: Is the grouping logical? Are transitions smooth?
3. Writing Quality: Academic tone, citation style consistency
4. Completeness: Are all papers discussed substantively?
5. Specific Revisions: 5-10 actionable changes with priority (HIGH/MEDIUM/LOW)
6. Overall Score: X/10 with top 3 strengths and weaknesses

4b: Revision Agent

Reads review_report.md, survey.tex, paper_summaries.md. Implements ALL revision suggestions. Saves to survey_v2.tex.

Final compilation:

cd {WORKDIR}
pdflatex -interaction=nonstopmode survey_v2.tex
bibtex survey_v2
pdflatex -interaction=nonstopmode survey_v2.tex
pdflatex -interaction=nonstopmode survey_v2.tex

Verify zero errors in the final PDF.

Step 5: Deliver

Report to the user:

• Total papers found per journal
• PDF download success rate
• Review score and key improvements made
• Final PDF page count and location
• List all deliverables in the working directory

Critical Rules

1. File handoff, not context handoff: Every agent saves its output to a file. Never pass large content back to the main agent. Agents return only a status summary (paper count, success/failure, file paths).

2. Parallel where possible, sequential where required: Phases 1 and 2 are parallel internally. Phase 3 depends on Phase 2 outputs. Phase 4 is sequential (review before revision).

3. All agents get mode: auto: Subagents need Bash, Read, Write, Edit access to do their work without permission prompts.

4. Verify before proceeding: Always compile LaTeX and check for errors between phases. Don't hand broken output to the next phase.

5. Be transparent about relevance: Not every paper returned by keyword search is centrally about the topic. The survey should acknowledge varying degrees of relevance rather than force-fitting papers into the narrative.

6. Respect API rate limits: OpenAlex (add mailto), CrossRef (add mailto), Semantic Scholar (3s between calls), arXiv (3s between calls).

Customization Points

• Different journals: Change the journal table. For any journal, look up its OpenAlex source ID first.
• Different output format: Swap LaTeX template for Markdown if user prefers.
• Broader search: Add NBER, SSRN, arXiv searches in Phase 1 using the academic-paper-search skill's API patterns.
• Deeper review: Add a second review-revise cycle if the first review score < 7.
• Zotero import: After Phase 2, optionally import all papers via zotero_add_by_doi.
