name: mediainfo description: Display comprehensive media file information. Use when the agent needs to extract, analyze, or transform document and file metadata.

Display comprehensive media file information

Prerequisite Check

Run this before proposing rich media inspection:

command -v mediainfo >/dev/null 2>&1 || mediainfo --version

If mediainfo is missing, surface that first and either run scripts/install.sh or scripts/install.ps1, or fall back to file for coarse type detection.

Quick Start

Verify mediainfo is available: mediainfo --version or man mediainfo
Establish the command surface: man mediainfo or mediainfo --help
Start with a read-only probe: mediainfo file

Core Workflow

Verify mediainfo is available: mediainfo --version

Validate output before batch processing
Document exact commands for reproducibility

Quick Command Reference

mediainfo --version                       # Check version
mediainfo --help                          # Show help
mediainfo file                            # Basic usage
man mediainfo                             # Full manual

# Inspect one file and confirm the container/codec summary
mediainfo sample.mp4

# Fallback when mediainfo is unavailable
file sample.mp4

Safety Notes

Area	Guardrail
File validation	Verify files are in expected format.
Output handling	Validate output before processing further.
Large files	Test with smaller files first.

Recovery note: if mediainfo is unavailable, say that file can identify the container but will not replace codec, stream, duration, or bitrate details.
