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 A, and why

gsp-color scanned grade A with 0 findings 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 11d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This is a standalone composable skill. It works two ways:

  1. Standalone — user runs /gsp-color directly for palette exploration, contrast checking, or full system design
  2. As a building block — the creative-director invokes /gsp-color --enrich to add technical precision to creative color choices

Input: Hex colors, --preview, --enrich, or interactive Output: color-system.md chunk + palettes.json (OKLCH scales) Agent: None — inline skill, deterministic palette generation + contrast math

<execution_context> @${CLAUDE_SKILL_DIR}/chunk-format.md </execution_context>

Input Mode Domain
/gsp-color #hex [#hex...] --preview Preview scales palette
/gsp-color #hex [#hex...] Generate from hex palette
/gsp-color --enrich Enrich existing system system
/gsp-color Interactive full system system

Step 1: Load domain

Read the domain file for the detected mode:

  • palette mode → Read ${CLAUDE_SKILL_DIR}/domains/palette.md
  • system mode → Read ${CLAUDE_SKILL_DIR}/domains/system.md

Changes

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.
