Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00073 | $0.00689 |
| Opus 5 | $0.00036 | $0.00345 |
| Sonnet 5 | $0.00015 | $0.00138 |
| Haiku 4.5 | $0.00007 | $0.00069 |
Grade A, and why
markitdown 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
### Convert from URL (via curl) How it starts
The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
markitdown
Command-line tool for converting various file formats to Markdown. Built by Microsoft for LLM and text analysis pipelines.
Basic Usage
markitdown document.pdf # Convert, output to stdout
markitdown document.pdf -o output.md # Convert, write to file
cat document.pdf | markitdown # Convert from stdin
markitdown document.pdf > output.md # Redirect stdout to file
markitdown < document.pdf # Redirect stdin
Supported Formats
Converted without any extras: HTML, CSV, JSON, XML, plain text, ZIP (iterates contents), EPub, Jupyter notebooks (.ipynb), RSS feeds, Wikipedia URLs, Bing SERP results.
With extras installed: PDF, DOCX, PPTX, XLSX, XLS, Outlook MSG, images (EXIF metadata + optional LLM captioning), audio (EXIF metadata + optional transcription), YouTube URLs (transcript extraction).
Options
markitdown -v # Show version
markitdown -o FILE # Write output to file instead of stdout
markitdown -x .pdf # Hint file extension (useful with stdin)
markitdown -m application/pdf # Hint MIME type
markitdown -c UTF-8 # Hint charset
markitdown --keep-data-uris # Keep base64-encoded data URIs in output (truncated by default)
Azure Document Intelligence
For higher-quality extraction using cloud OCR:
markitdown -d -e "https://your-endpoint.cognitiveservices.azure.com" document.pdf
Plugins
Third-party plugins extend format support via the markitdown.plugin entry point:
markitdown --list-plugins # List installed plugins
markitdown -p document.xyz # Enable plugins for conversion
Common Patterns
Convert a file and pipe to another tool
markitdown report.pdf | wc -w # Word count
markitdown report.pdf | head -50 # Preview first 50 lines
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.

markitdown is a skill published in the GitHub repository fprochazka/claude-code-plugins (11 stars, last pushed 4d ago), licensed MIT. It adds 73 tokens to every session and 689 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
