yume: Skill for Claude Code

.claude/skills/md-to-html/SKILL.md

md-to-html is a skill for Claude Code from kamwoh/yume. It costs 74 tokens per session (1,567 once invoked), scanned A, original, MIT.

A converter that turns a Markdown design document into a self-contained HTML page. Markdown is plain text with simple formatting marks, while HTML is the format used by web browsers.

In plain words
What is it for?
Rendering game design documents, milestone plans, architecture decision records, and other Markdown files as browser-ready pages.
Why use it?
It makes design documents easier to read, share, print, and navigate than raw Markdown, including long documents split into linked pages.

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

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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (convert.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 — 156 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 Read directly)
  • 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)

Files

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.

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.
