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 | $0.00047 | $0.01549 |
| Opus 5.5 | $0.00019 | $0.00620 |
| Sonnet 5.5 | $0.00009 | $0.00310 |
| Haiku 4.5 | $0.00005 | $0.00155 |
Grade A, and why
md-to-html 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 12d 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
The opening of the file, as written. The whole thing — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/md-to-html — Markdown → HTML converter
Renders a markdown file (typically a design doc, ADR, or GDD) as styled HTML. For long docs (> ~800 lines of HTML output), splits into one page per H2 section with an index + prev/next navigation. No external dependencies — pure Python stdlib.
When to invoke this skill
- User says "convert this to HTML", "render as HTML", "view this in a browser"
- User wants to share or print a design doc
- A long design doc (GDD, milestone spec, ADR) would benefit from per-section pagination + a clickable TOC
- User asks for a stylable / reflow-friendly version of a markdown file
When NOT to invoke
- The user just wants you to read the markdown (use
Readdirectly) - The markdown is a code-comment or inline snippet (no value)
- The user wants the actual file edited (use
Edit, not this skill)
Usage
python3 .claude/skills/md-to-html/convert.py <input.md> [--out-dir DIR] [--split N]
Arguments:
| Flag | Default | Purpose |
|---|---|---|
input |
— (required) | Path to a .md file |
--out-dir DIR |
input's directory | Where to write the .html output (and _pages/ subfolder if split) |
--split N |
800 | Threshold (lines of HTML output) before splitting into multiple files |
Output layout
Short doc (HTML output ≤ split threshold):
<input-dir>/
├── <stem>.md
└── <stem>.html ← single page, embedded TOC + CSS
Long doc (HTML output > split threshold):
<input-dir>/
├── <stem>.md
├── <stem>.html ← index: preamble + ToC linking to each split
└── <stem>_pages/
├── 00-overview.html ← optional preamble (everything before the first H2)
├── 01-<slug-of-first-h2>.html
├── 02-<slug-of-second-h2>.html
└── … ← prev/next nav between adjacent pages; "Index" link back
Each page has:
- Embedded CSS (light + dark mode via
prefers-color-scheme) - A clickable in-page Table of Contents (H1/H2/H3 entries)
- Top-bar nav: index link (left) + prev/next page links (right)
- Anchor links from headings (clickable + URL-shareable)
What ships with it
1 file 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.
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.

md-to-html is a skill published in the GitHub repository kamwoh/yume (25 stars, last pushed 10d ago), licensed MIT. It adds 47 tokens to every session and 1,549 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
