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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 5.1 | $0.00036 | $0.01267 |
| Opus 5 | $0.00018 | $0.00633 |
| Sonnet 5 | $0.00007 | $0.00253 |
| Haiku 4.5 | $0.00004 | $0.00127 |
Grade A, and why
document-conversion 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 8d 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.
How it starts

Document Conversion
Purpose
Convert documents between formats while preserving the structure that matters. Most conversion tools preserve the text and destroy the structure, which is usually the part you needed.
When to Use
- Converting a web page or an HTML document to Markdown.
- Converting Word, PDF, or HTML into a text format for processing.
- Generating a PDF from HTML or Markdown.
- Normalizing a mixed corpus into one format.
Capabilities
- HTML to Markdown, with structure preserved.
- Office formats to Markdown or plain text.
- Markdown or HTML to PDF, with proper pagination.
- Batch conversion and normalization.
- Content extraction from web pages, discarding the navigation.
Inputs
- The source documents and their formats.
- What must survive the conversion: headings, tables, links, code blocks, images.
- The target format and what it can represent.
Outputs
- Converted documents with their structure intact.
- A report of what could not be preserved.
Workflow
- Decide what must survive — Headings and tables usually must. Fonts and exact spacing usually must not. Naming this first prevents a great deal of wasted effort on preserving things nobody needs.
- Extract the content, not the page — A web page is 80% navigation, cookie banners, and related-articles rails. Convert the article, not the chrome.
- Use a converter that understands the structure — A regex that strips HTML tags produces a wall of text with no headings and no tables. Use a real parser.
- Handle the tables specially — They are the most commonly destroyed structure. Verify them after conversion.
- Verify a sample — Open the output next to the input and compare. Conversion failures are usually silent.
Best Practices
- Structure is what makes a document useful. A conversion that produces correct text with no headings has thrown away the navigation, the outline, and every chunking boundary a downstream system would use.
- Tables convert badly by default and are frequently the highest-value content. Check them explicitly.
- Code blocks lose their language annotation in most conversions. If the corpus is technical, that matters.
- When converting HTML, strip the navigation, the footer, and the scripts before converting, not after — an extraction library that identifies the main content does this far better than a hand-written selector.
- PDF generation from HTML requires a real browser engine for anything with modern CSS. Older HTML-to-PDF libraries silently ignore flexbox and grid, and the output looks nothing like the page.
- Preserve the source URL or path in the output. A converted document with no provenance is unverifiable.
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.

document-conversion is a skill published in the GitHub repository nimadorostkar/Claude-Skills-collection (26 stars, last pushed 24d ago), licensed MIT. It adds 36 tokens to every session and 1,267 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
