What it does
Extract From Pdfs is an agent skill from aiskillstore/marketplace. This skill should be used when extracting structured data from scientific PDFs for systematic reviews, meta-analyses, or database creation. Use when working with collections of research papers that need to be converted into analyzable datasets with validation metrics.
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 23 other files, including scripts, reference files and assets (for example `README.md`, `assets/api_config_template.json` and `assets/example_api_config_ecology.json`).
It sits in Documents & Office, covering Schema markup, PDF and Literature review. It works with Python. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Working with collections of research papers that need to be converted into analyzable datasets with validation metrics
- Tasks that involve Schema markup
- Tasks that involve PDF
Example prompts
- “/extract-from-pdfs”
Requirements
- Python 3
- A credential in ANTHROPIC_API_KEY
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Initial Setup
- Define Extraction Requirements
- Design Extraction Schema
What it can do on your machine
Read from SKILL.md and the folder at commit 44923f3. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 6 files in scripts/ (Python, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
pythonconda
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
ANTHROPIC_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Extract From Pdfs loads about 2.2k tokens when it runs, and up to ~9.3k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 747 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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 747 words (~2,213 tokens).
“Extract standardized, structured data from scientific PDF literature using Claude's vision capabilities. Transform PDF collections into validated databases ready for statistical analysis in Python, R, or other frameworks.”
