Markdown Converter

Convert files to beautifully formatted Markdown in two steps: convert with uvx markitdown[all], then beautify with configurable style formatting.

Usage

/1coos-markdown-converter <file-path> [--style github|commonmark|clean|obsidian] [--output-dir path] [--convert-only]

Parameters

Parameter	Required	Description
`<file-path>`	Yes	Path to the file to convert
`--style`	No	Formatting style: `github` (default), `commonmark`, `clean`, `obsidian`
`--output-dir`	No	Output directory (default: `skills/1coos-markdown-converter/output`)
`--convert-only`	No	Only convert, skip formatting step
`--config`	No	Path to config.json (default: skill directory config.json)

Supported Formats

Documents: PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx, .xls)
Web/Data: HTML, CSV, JSON, XML
Media: Images (EXIF + OCR), Audio (EXIF + transcription)
Other: ZIP (iterates contents), YouTube URLs, EPub

Formatting Styles

github (default)

GitHub Flavored Markdown — table column alignment, fenced code blocks, task lists.

commonmark

Strict CommonMark — enforces sequential heading levels (no skipping h1 to h3).

clean

Minimal style — removes excessive formatting, simplifies redundant links.

obsidian

Obsidian Flavored Markdown — converts internal links to [[wikilinks]], normalizes callout syntax (> [!type]), formats properties/frontmatter, normalizes ==highlight== syntax, and aligns tables. Ideal for notes destined for Obsidian vaults.

Configuration

Core parameters are configurable via config.json in the skill directory:

{
  "style": "github",
  "outputDir": null,
  "convertOnly": false,
  "formatting": {
    "maxWidth": 80,
    "listMarker": "-",
    "emphasisMarker": "*",
    "strongMarker": "**",
    "codeBlockStyle": "fenced"
  },
  "converter": {
    "timeout": 60000,
    "charset": "UTF-8"
  }
}

CLI arguments always override config.json values.

Execution Instructions

When the user invokes this skill:

Check prerequisites: Verify uvx is available. If not, instruct the user to install uv: curl -LsSf https://astral.sh/uv/install.sh | sh

Run conversion: Execute the script:

bun run ${CLAUDE_SKILL_DIR}/scripts/main.ts $ARGUMENTS

Report results: Show the output file path and a brief summary of the conversion.
Handle errors:
- Exit code 2: argument error — show the specific error message
- Exit code 3: missing dependency — guide user to install uv
- Exit code 4: conversion failure — suggest checking file format support

Examples

# Convert a PDF with default github style
/1coos-markdown-converter report.pdf

# Convert Word document with clean style
/1coos-markdown-converter document.docx --style clean

# Convert Excel to markdown without formatting
/1coos-markdown-converter data.xlsx --convert-only

# Specify output directory
/1coos-markdown-converter slides.pptx --output-dir ~/notes

Notes

First run caches markitdown[all] dependencies; subsequent runs are faster
Uses markitdown[all] to ensure full format support (PDF, OCR, audio transcription)
Output preserves document structure: headings, tables, lists, links
For complex PDFs with poor extraction, consider using Azure Document Intelligence
