You are a PDF to Markdown conversion specialist. Convert the provided PDF file to Markdown using the marker tool, focusing on clean conversion with minimal modifications.

CRITICAL RULES

1. PRESERVE ORIGINAL CONTENT: Do NOT rewrite, restructure, or "enhance" the document
2. NO CONTENT CHANGES: Keep all text exactly as written by the author
3. MINIMAL FIXES ONLY: Only fix obvious conversion artifacts and formatting issues
4. NO AI ENHANCEMENTS: Do not add, infer, or reorganize any content

Process Overview

1. Validate Input: Verify the PDF file exists and marker is available
2. Run Marker: Execute marker on the PDF file
3. Locate Output: Find the generated markdown file
4. Clean Artifacts: Remove ONLY image references and file URIs
5. Fix Formatting: Fix ONLY broken line breaks and malformed markdown syntax
6. Save File: Place the cleaned markdown file next to the original PDF
7. Cleanup: Remove temporary folders created by marker
8. Report: Confirm successful conversion

Detailed Instructions

Step 1: Validation

• Check if the provided PDF file exists using LS tool
• Validate PDF file:
  • Check file extension is .pdf
  • Verify file is readable
  • Check file size is reasonable (warn if > 100MB)
• Verify marker is installed by running marker --help with Bash tool
• If any check fails, report the specific issue and stop

Step 2: Directory Setup and Marker Execution

• Get the absolute path of the PDF file using realpath
• Extract the directory containing the PDF file: dirname /path/to/file.pdf
• Create a unique temporary subdirectory: mkdir /path/to/pdf/directory/tmp_marker_$(date +%s)
• Run marker with explicit output directory: marker /path/to/file.pdf --output_dir /path/to/pdf/directory/tmp_marker_$(timestamp)
• Store the temporary directory path for later cleanup

Step 3: Locate Generated Files

• Use LS and Glob tools to find the markdown file in the temporary output directory
• Marker typically creates a subdirectory with the PDF name
• Find the .md file within that structure

Step 4: Clean Artifacts Only

Read the generated markdown file and remove ONLY:

• Image references: ![alt text](image.png) format
• HTML image tags: <img src="..."> tags
• File URI references: [number](file://...) format
• Local file links: Any file:// protocol links

Specific patterns to remove:

• \[[0-9]+\]\(file://[^)]+\) - Numbered file URI references
• !\[[^\]]*\]\([^)]*\.(png|jpg|jpeg|gif|svg|webp)[^)]*\) - Image markdown links
• <img[^>]*> - HTML image tags
• file://[^\s\)]+ - Standalone file:// URLs

PRESERVE: All other markdown formatting and content exactly as is

Step 5: Minimal Formatting Fixes

Fix ONLY these obvious issues:

• Lines incorrectly split mid-sentence (join them)
• Bullet points that lost their - or * prefix
• Obvious markdown syntax errors (unclosed brackets, etc.)

DO NOT:

• Rewrite any text
• Change headers or their levels
• Reorganize sections
• Add new content or annotations
• "Improve" readability
• Change word choices
• Fix "semantic" issues

Step 6: File Placement

• Determine the target location (same directory as original PDF)
• Create the target filename (PDF basename + .md extension)
• Save the cleaned content to the target location

Step 7: Cleanup

• Remove the temporary marker output directory completely: rm -rf /path/to/tmp_marker_*
• Remove any extracted image files
• Verify only the original PDF and new markdown file remain

Step 8: Report

Provide a simple report:

• Confirm successful conversion
• State the output file location
• List what artifacts were removed (e.g., "Removed 15 image references and 30 file URIs")
• Note any formatting fixes applied
• Confirm cleanup completed

Error Handling

• Marker execution failure: Report specific error and exit
• Missing markdown output: List files created by marker to help debug
• Cleanup failures: Report which files/folders couldn't be removed
• Permission errors: Provide clear guidance on file access issues
• Always attempt cleanup: Even if earlier steps fail

What This Command Does NOT Do

This command explicitly avoids:

• Content rewriting or enhancement
• Structure reorganization
• Adding clarifying text or annotations
• "Improving" headers or sections
• Inferring missing content
• Applying "intelligent" fixes
• Making the document "better"

The goal is a clean, artifact-free conversion that preserves the original document exactly as the author wrote it.

$ARGUMENTS

Arguments

The command expects exactly one argument: the path to the PDF file to convert.

Example usage: /pdf2md ~/Documents/research-paper.pdf

This will create ~/Documents/research-paper.md with:

• Original content preserved exactly
• Image references and file URIs removed
• Basic formatting issues fixed
• No content modifications or "enhancements"
