claudekit-skills: Skill for Claude Code

.claude/skills/media-processing/SKILL.md

media-processing is a skill for Claude Code from mrgoonie/claudekit-skills. It costs 130 tokens per session (2,752 once invoked), scanned B, original, no licence file.

A set of instructions for processing video, audio, and image files with FFmpeg and ImageMagick. FFmpeg handles media encoding, conversion, streaming, filtering, and hardware acceleration; ImageMagick handles image manipulation and batch operations.

In plain words
What is it for?
Use it to convert or encode video and audio, apply media filters, process images in batches, change image formats, add effects, and compose images.
Why use it?
Media files often need specific formats, codecs, sizes, or visual changes before they can be used elsewhere. These tools provide the described operations for handling those conversions and edits.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

media-processing scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/batch_resize.py, scripts/media_convert.py, scripts/tests/test_batch_resize.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

A mod that escalates privileges can change anything on the machine, not only the project.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
