File Diff

Compare two files and display differences in a clean, readable markdown format.

Usage

Quick Compare (Two file paths)

diff \x3Csource_file> \x3Ctarget_file>

Unified Diff Format (Recommended)

diff -u \x3Csource_file> \x3Ctarget_file>

Output Format

The diff output is formatted as:

**File A**: `/path/to/file1`
**File B**: `/path/to/file2`

## Differences

### 1. [Section/Line description]
```diff
- removed line
+ added line

## Workflow

1. Identify the two files to compare
2. Run `diff -u` command
3. Parse the unified diff output
4. Format into readable markdown with:
   - File paths as headers
   - Line numbers from diff output
   - `-` prefix for removals (red)
   - `+` prefix for additions (green)
   - Context lines for clarity

## Example

Input:
```bash
diff -u /tmp/original.txt /tmp/modified.txt

Output format:

**File A**: `/tmp/original.txt`
**File B**: `/tmp/modified.txt`

## Differences

### Line 5
```diff
- old content
+ new content

## Notes

- Always use `-u` flag for unified format (more readable)
- Include both file paths in the output
- Preserve all changes including additions, deletions, and modifications
