color-management

color-management is a skill for Claude Code, Codex from magnus919/agent-skills. It costs 82 tokens per session (2,475 once invoked), scanned B, original, MIT.

A reference and toolset for managing color spaces, ICC profiles, gamut, and color conversions. An ICC profile describes how a device or color space represents colors.

In plain words
What is it for?
Inspecting profiles, converting images, checking colors outside a gamut, soft-proofing, comparing sRGB variants, and measuring image color differences.
Why use it?
It helps identify color-management problems and check whether conversions or working spaces will change colors unexpectedly.

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

color-management 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 8d ago.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/color-difference.py, scripts/color-report.py, scripts/color-space-convert.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.

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.
