alterlab-pdf-explore

alterlab-pdf-explore is a skill for Claude Code from AlterLab-IEU/AlterLab-Academic-Skills. It costs 150 tokens per session (974 once invoked), scanned A, original, MIT.

A tool for exploring one PDF in depth after parsing it once. A PDF is a document format; the tool can answer questions across its sections, figures, tables, and appendices, including values shown in charts.

In plain words
What is it for?
Use it to compare sections, find every occurrence of a pattern, inspect methods and results, and extract values from figures or tables in one paper or report.
Why use it?
It avoids repeatedly reading the same paper or report from scratch and keeps related answers tied to one document. It is intended for a deep dive into a single document, not comparison across many documents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

alterlab-pdf-explore scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

PDF Explore (deep single-document Q&A)

Overview

Reading one paper or report thoroughly means jumping between the methods, a results figure, a supplementary table, and an appendix — repeatedly. This skill parses a PDF once into a reusable index of sections, figures, and tables, then answers many questions across the whole document without re-parsing: compare what two sections say, extract every instance of a pattern, and read values off charts/tables.

It is the single-document deep-dive counterpart to the corpus-level tools: to build a comparison table across many papers use alterlab-pdf-extract; to just convert a PDF to Markdown use alterlab-markitdown.

When to Use This Skill

Use this skill when the user wants to:

  • Interrogate one paper/report end-to-end (methods vs. results vs. appendix).
  • Extract every occurrence of a pattern within a document (all p-values, all sample sizes, every mention of a gene).
  • Read data off a figure or table inside the PDF.
  • Feed precise, located answers into the literature-review or paper-review pipeline.

Does NOT Trigger

Scenario Use instead
Build a comparison table across many papers (one row per paper) alterlab-pdf-extract
Convert a PDF/DOCX to clean Markdown alterlab-markitdown
Manage references / DOIs / BibTeX alterlab-pyzotero
Work with a Jupyter notebook alterlab-open-notebook

Core Capabilities

1. Parse-once, ask-many

Parse the PDF a single time into a structured index — page text with layout, detected section headings, figure/table regions, and (for scans) OCR'd text — then answer subsequent questions against that index instead of re-reading the file each time.

2. Cross-section questions

Answer questions that span the document: "does the discussion's claim match the methods' design?", "which limitations does the appendix add beyond the main text?". Cite the page and section for every answer so it is verifiable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
