mineru-pdf-to-md

mineru-pdf-to-md is a skill for Claude Code, Codex from Tano73/agent-skills. It costs 274 tokens per session (3,228 once invoked), scanned A, original, MIT.

A document-conversion tool that turns PDFs and images into Markdown while preserving complex page layouts, tables, formulas, and extracted images. It uses MinerU, an AI model that reads pages as images, and may require a GPU or remote server.

In plain words
What is it for?
Use it to convert scientific papers, scanned documents, specifications, and other layout-heavy PDFs into Markdown.
Why use it?
Basic text extraction can lose columns, table structure, formulas, or content from scanned pages; this tool is designed to retain that structure.

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

mineru-pdf-to-md 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 1mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/mineru_convert.py, scripts/mineru_env.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 229 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MinerU PDF → Markdown

MinerU converte documenti a layout complesso in Markdown pulito. Il suo modello di punta è MinerU2.5-Pro-2604-1.2B, un VLM che legge la pagina come immagine e ne ricostruisce la struttura: ordine di lettura, tabelle in HTML, formule in LaTeX, figure ritagliate su file.

Questo lo rende adatto dove un estrattore di testo tradizionale fallisce — PDF a due colonne, scansioni, paper scientifici, capitolati con tabelle annidate — ma comporta un vincolo concreto: il VLM ha bisogno di una GPU o di un server remoto. Il primo compito della skill è quindi capire dove può girare, non lanciare subito la conversione.

Script:

  • $HOME/.agents/skills/mineru-pdf-to-md/scripts/mineru_env.py — diagnosi ambiente e installazione
  • $HOME/.agents/skills/mineru-pdf-to-md/scripts/mineru_convert.py — conversione, normalizzazione output, report qualità

Fase 0 — Diagnosi dell'ambiente

Esegui sempre questo comando prima di qualsiasi conversione. È veloce e determina tutto il resto:

python3 $HOME/.agents/skills/mineru-pdf-to-md/scripts/mineru_env.py check

Lo script rileva GPU CUDA, Apple Silicon, un eventuale server VLM (variabili d'ambiente MINERU_SERVER_URL o MINERU_VLM_SERVER_URL) e la presenza di mineru, poi raccomanda un backend.

Situazione rilevata Backend scelto Usa MinerU2.5-Pro?
Server OpenAI-compatibile raggiungibile vlm-http-client Sì, in remoto
GPU CUDA ≥ 8 GB VRAM o Apple Silicon hybrid-auto-engine Sì, in locale
Solo CPU, nessun server pipeline No

Il caso CPU va dichiarato all'utente

Se la raccomandazione è pipeline, la conversione funzionerà comunque — MinerU ha una pipeline classica (layout detection + OCR) che gira bene su CPU — ma MinerU2.5-Pro non viene usato, e tabelle e formule risultano sensibilmente più deboli. Siccome l'utente ha probabilmente chiesto proprio quel modello, non silenziare la differenza: spiega il fallback e presenta le alternative reali (procedere con pipeline, puntare a un server remoto con --server-url, oppure forzare vlm-auto-engine su CPU, che usa davvero MinerU2.5-Pro ma impiega diversi minuti a pagina).

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
