ai-asset-pricing: Skill for Claude Code

.claude/skills/split-pdf/SKILL.md

split-pdf is a skill for Claude Code from Alexander-M-Dickerson/ai-asset-pricing. It costs 46 tokens per session (2,236 once invoked), scanned A, original, MIT.

A tool for downloading and reading academic papers in PDF form in smaller sections. It creates structured notes, with a focus on empirical finance papers.

In plain words
What is it for?
Use it to fetch a paper, split it into manageable parts, and extract information about its methods, data, and findings.
Why use it?
It avoids trying to process a long paper all at once, which can cause missed details or unreliable summaries.

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

split-pdf scanned grade A with 1 finding 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 10d 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.

Split-PDF: Download, Split, and Deep-Read Academic Papers

CRITICAL RULE: Never read a full PDF in one pass. Only read the split files, and only one batch at a time. Reading a full PDF will either crash the session with an unrecoverable "prompt too long" error -- destroying all context -- or produce shallow, hallucinated output where Claude skims the abstract, gets fuzzy on methodology, and fabricates details from results sections.

When This Skill Is Invoked

The user wants to read, review, or summarize an academic paper. The input is either:

  • A file path to a local PDF (e.g., ./articles/smith_2024.pdf)
  • A search query or paper title (e.g., "Bai Bali Wen 2019 corporate bond factors")

You must know what paper to read. If the user invokes this skill without specifying a paper, ask them. Do not guess.

Step 1: Acquire the PDF

If a local file path is provided:

  • Verify the file exists
  • If not already in ./articles/, copy it there (preserve original)
  • Proceed to Step 2

If a search query is provided:

  1. Use Perplexity MCP tools to find the paper (prefer perplexity_search)
  2. Use Bash (curl/wget) to download the PDF
  3. Save to ./articles/ (create directory if needed)
  4. Proceed to Step 2

CRITICAL: Always preserve the original PDF. The original in articles/ must NEVER be deleted, moved, or overwritten. Split files are derivatives.

Step 2: Determine Chunk Size (Adaptive)

Before splitting, determine total page count and select the optimal chunking strategy:

from PyPDF2 import PdfReader
import os

reader = PdfReader(input_path)
total_pages = len(reader.pages)

Chunking strategy by paper length:

Paper Length Action Chunk Size Batch Size Pages/Batch
< 12 pages Read directly (no splitting) -- -- --
12-25 pages Light splitting 8 pages 2 chunks ~16 pages
25-45 pages Standard splitting 6 pages 3 chunks ~18 pages
45-80 pages Dense splitting 5 pages 3 chunks ~15 pages
> 80 pages Heavy splitting 4 pages 3 chunks ~12 pages

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.
