SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Converting large collections of academic PDFs into a token-efficient, easily navigable knowledge base by generating a two-tier markdown wiki with an index and papers/*.md for on-demand reading.

Core Features & Use Cases

Two-tier structure: index.md with metadata and abstracts, and papers/*.md with full, cleaned markdown for on-demand reading.
Incremental conversions: only new or changed PDFs are processed when possible.
BibTeX matching to attach citekeys when a .bib file is provided.
Obsidian-ready vault format with YAML frontmatter and wiki-style linking for fast searching.
Token savings: dramatically reduces token usage when referencing a large library of papers.

Quick Start

Provide the PDF_DIR and WIKI_DIR to start generating the token-efficient literature wiki.

FAQPage Schema

How do I convert a directory of academic PDFs into a markdown wiki for Obsidian?▼

This Skill processes a PDF directory to create a token-efficient two-tier markdown wiki with an index and per-paper notes, featuring Obsidian-ready YAML frontmatter and wiki-style linking for fast vault searching.

What is the best way to reduce token usage when referencing a large library of economics papers?▼

A two-tier wiki structure reduces token usage by keeping an index of metadata and abstracts separate from full per-paper markdown files, allowing on-demand reading and dramatically cutting token consumption for large economics literature libraries.

Can I use a BibTeX file to attach citation keys to extracted PDF markdown notes?▼

Yes, BibTeX matching is supported. By providing a .bib file alongside your PDF directory, the conversion process matches entries and attaches corresponding citekeys to the generated per-paper markdown notes.

Does incremental PDF to markdown conversion skip previously processed files?▼

Yes, incremental processing is supported. The converter detects new or changed PDFs in the directory and processes only those files, efficiently updating the markdown wiki index and per-paper notes without reprocessing the entire library.

How does PDF to markdown wiki conversion handle scanned PDFs and extraction errors?▼

The conversion includes error handling specifically designed for typical scanned PDFs. It manages metadata extraction and text cleaning gracefully, preventing processing failures when encountering poorly scanned academic literature.
