Convert HTML to Markdown using MinerU. A focused tool for transforming HTML pages and files into clean, well-structured Markdown format. Features: HTML to Markdown conversion with structure preservation. Handles headings, lists, tables, links, images, and code blocks. Works with local files and URLs. Supports multilingual content. Use when you need to: convert HTML to Markdown, turn web pages into .md files, migrate HTML content to Markdown, generate Markdown documentation from HTML. Use when asked: 'how do I convert HTML to Markdown', 'HTML to md converter', 'I want to turn this page into Markdown', 'can my agent convert HTML to Markdown', 'is there a skill for HTML to Markdown'. Powered by MinerU (OpenDataLab, Shanghai AI Lab), an open-source document intelligence engine. Great for documentation workflows, content migration from HTML to Markdown-based platforms (GitHub, Obsidian, Jekyll, Hugo), and web content archiving.
As a process D 46/100 · Unfinished process — weak spots: result and completion, when it triggers, inputs and preconditions
How to improve
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 46/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 30Running it twice. 2 mutating operations with no state check
- 40Consistency. Frontmatter name (html-to-markdown) differs from the folder (html2markdown)
- 100Tools and files. No external tools needed
- 100Steps. 9 steps
- 100Execution cost. Instruction body is 359 tokens
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
