A file converter that turns PDF, Word, PowerPoint, Excel, HTML, or audio files into Markdown, a plain-text format that preserves basic structure. The converted text can then be analyzed.

Use it when someone provides a document or audio file and asks to read it, extract its text, or convert it before analysis.

It removes the need to work directly with formats that are difficult for text analysis tools to read.

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.

Model	Per session	Once invoked
Fable 5	$0.00054	$0.00226
Opus 5	$0.00027	$0.00113
Sonnet 5	$0.00011	$0.00045
Haiku 4.5	$0.00005	$0.00023

Security

Grade A, and why

convert 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 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.

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.

What it actually says

Nutritious.md — Document to Markdown Converter

When the user references a file that isn't plain text (.pdf, .docx, .pptx, .xlsx, .xls, .html, audio), run:

${CLAUDE_PLUGIN_ROOT}/scripts/setup_env.sh
${CLAUDE_PLUGIN_ROOT}/.venv/bin/python ${CLAUDE_PLUGIN_ROOT}/scripts/convert.py "<file path>"

Parse the returned JSON's markdown field and use it as the document's content going forward. If the JSON contains a warning field about empty text extraction, tell the user the file may be a scanned/image-only document and no OCR is available. If the JSON contains an error field, tell the user the conversion failed and report the error message.

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.
