# Convert PPTX → Markdown

Convert the PowerPoint file at `$1` to clean markdown format optimized for LLM context.

## Steps

1. **Install dependency**: Use `toolsmith:install-dependency` skill to ensure `markitdown` is installed
2. **Parse arguments**: Input file `$1` (required), output dir `$2` (optional, defaults to `./converted/`)
3. **Prepare output dir**: Create `$2` if it doesn't exist
4. **Convert**:
   ```bash
   source .venv/bin/activate && python -m markitdown "$1" -o "$OUTPUT_DIR/output.md"
   ```
5. **Report**: Output location, file sizes, structure summary (slide count, headings, tables, images), any warnings

## Goal

Extract clean markdown for LLM context — analysis, summarization, Q&A. NOT for round-tripping back to PPTX.

No content sent to any LLM during conversion (pure script-based extraction).
