What it does
Split PDF is an agent skill from scunning1975/MixtapeTools. Download, split, and deeply read academic PDFs. Use when asked to read, review, or summarize an academic paper. Splits PDFs into 4-page chunks, reads them in small batches, and produces structured reading notes — avoiding context window crashes and shallow comprehension.
Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `methodology.md`).
It sits in Documents & Office, covering PDF and Context engineering. The repository describes itself as: Tools for coding, teaching, and presentations with AI assistance.
When your agent uses it
- Summarize an academic paper
- Tasks that involve PDF
- Tasks that involve Context engineering
Example prompts
- “/split-pdf”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Bash(python*), Bash(pip*), Bash(curl*), Bash(wget*), Bash(mkdir*), Bash(ls*), Read, Write, Edit, WebSearch, WebFetch, Agent
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Acquire the PDF
- Split the PDF
- Read in Batches of 3 Splits
- Structured Extraction
What it can do on your machine
Read from SKILL.md and the folder at commit 9163a2e. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash(python*)Bash(pip*)Bash(curl*)Bash(wget*)Bash(mkdir*)Bash(ls*)ReadWriteEditWebSearch
…and 2 more on the same allowed-tools line.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pip
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
mccombs.utexas.edu
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Split PDF loads about 2.9k tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 1,304 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,304 words (~2,897 tokens).
“CRITICAL RULE: Never read a full PDF. Never. Only read the 4-page split files, and only 3 splits at a time (~12 pages). Reading a full PDF will either crash the session with an unrecoverable "prompt too long" error —…”
