markitdown
CLI for converting files to Markdown using Microsoft's markitdown.

Triggered by requests involving file-to-markdown conversion, document text extraction, or preparing files for LLM input.
What this skill does
# markitdown
Command-line tool for converting various file formats to Markdown. Built by Microsoft for LLM and text analysis pipelines.
## Basic Usage
```bash
markitdown document.pdf # Convert, output to stdout
markitdown document.pdf -o output.md # Convert, write to file
cat document.pdf | markitdown # Convert from stdin
markitdown document.pdf > output.md # Redirect stdout to file
markitdown < document.pdf # Redirect stdin
```
## Supported Formats
Converted without any extras: HTML, CSV, JSON, XML, plain text, ZIP (iterates contents), EPub, Jupyter notebooks (.ipynb), RSS feeds, Wikipedia URLs, Bing SERP results.
With extras installed: PDF, DOCX, PPTX, XLSX, XLS, Outlook MSG, images (EXIF metadata + optional LLM captioning), audio (EXIF metadata + optional transcription), YouTube URLs (transcript extraction).
## Options
```bash
markitdown -v # Show version
markitdown -o FILE # Write output to file instead of stdout
markitdown -x .pdf # Hint file extension (useful with stdin)
markitdown -m application/pdf # Hint MIME type
markitdown -c UTF-8 # Hint charset
markitdown --keep-data-uris # Keep base64-encoded data URIs in output (truncated by default)
```
### Azure Document Intelligence
For higher-quality extraction using cloud OCR:
```bash
markitdown -d -e "https://your-endpoint.cognitiveservices.azure.com" document.pdf
```
### Plugins
Third-party plugins extend format support via the `markitdown.plugin` entry point:
```bash
markitdown --list-plugins # List installed plugins
markitdown -p document.xyz # Enable plugins for conversion
```
## Common Patterns
### Convert a file and pipe to another tool
```bash
markitdown report.pdf | wc -w # Word count
markitdown report.pdf | head -50 # Preview first 50 lines
```
### Batch convert multiple files
```bash
for f in *.pdf; do markitdown "$f" -o "${f%.pdf}.md"; done
```
### Convert from URL (via curl)
```bash
curl -sL "https://example.com/doc.pdf" | markitdown -x .pdf
```
### Convert and process with stdin extension hint
When piping content, provide an extension hint so markitdown can select the right converter:
```bash
cat unknown_file | markitdown -x .docx
```

rpg-migration-analyzer
IncludedAnalyzes legacy RPG (Report Program Generator) programs from AS/400 and IBM i systems for migration to modern Java applications. Extracts business logic from RPG III/IV/ILE source code, identifies data structures (D-specs), file operations (F-specs), program dependencies (CALLB/CALLP), and converts RPG constructs to Java equivalents. Generates migration reports, complexity estimates, and Java implementation strategies with POJO classes, JPA entities, and service methods. Use when modernizing AS/400 or IBM i legacy systems, analyzing RPG source files (.rpg, .rpgle, .RPGLE), converting RPG to Java, mapping data specifications to Java classes, planning legacy system migration, or when user mentions RPG analysis, Report Program Generator, RPG III/IV/ILE, AS/400 modernization, IBM i migration, packed decimal conversion, or mainframe application rewrite.
brand-library-architect
IncludedBuild a complete brand library for a product — visual asset render pipeline, brand documentation set (BRAND, COPY, MANIFESTO, BIOS, FAQ, GLOSSARY, TONE, PRICING), open-source convention files (README, CONTRIBUTING, SECURITY, CODE_OF_CONDUCT), and a self-contained press kit. This skill should be used when the user asks to "build a brand library / brand kit / press kit / brand assets" for a product, "set up a brand library workflow," "create a positioning manifesto plus visual identity," or any combination of brand documentation + visual asset pipeline. Apply phase-by-phase or run end-to-end. Templates are product-agnostic and use {{TOKEN}} placeholders the skill prompts the user to fill.
writing-tech-post
IncludedAuthors engineering blog posts end-to-end: launch deep-dives, incident postmortems, architecture migrations, performance case studies, tutorials, AI/agent system writeups, security disclosures, and research-to-product translations. Picks the correct archetype, plans the abstraction ladder, enforces an evidence cadence (diagrams, benchmarks, profiles, traces, code, ablations), tunes voice against publisher house styles (Datadog, Vercel, GitHub, AWS, Meta, Cloudflare, Jane Street), and runs a pre-publish gate for narrative momentum and disclosure ethics. Use when drafting a new engineering post, restructuring a draft that feels flat, deciding which evidence form belongs where, validating that depth and product context are balanced, or preparing a postmortem, migration, or performance narrative for external publication. Do not use for API reference documentation, README authoring, marketing copy, release notes, generic SEO content, ghost-written executive thought leadership, or non-engineering long-form essays.
