Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.02199 | $0.02199 |
| Opus 5 | $0.01099 | $0.01099 |
| Sonnet 5 | $0.00440 | $0.00440 |
| Haiku 4.5 | $0.00220 | $0.00220 |
Grade A, and why
pixel-plugin CLAUDE.md 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 2d 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

Project Overview
This is a Claude Code plugin that integrates Aseprite pixel art capabilities through the pixel-mcp Model Context Protocol server. The plugin enables pixel art creation, editing, and export using natural language commands.
Plugin Name: pixel-plugin Version: 0.1.0 Type: Claude Code Plugin (Skills + Commands + MCP Integration) Dependencies: pixel-mcp server (Go binary), Aseprite v1.3.0+
Architecture
The plugin follows a layered architecture:
- User Layer: Natural language or slash commands in Claude Code
- Plugin Layer: Skills (model-invoked) and Commands (user-invoked)
- MCP Layer: pixel-mcp server (40+ tools)
- Application Layer: Aseprite CLI interactions
Key Integration Point: The plugin bundles pre-compiled pixel-mcp binaries and provides a platform-detection wrapper (bin/pixel-mcp) that selects the correct binary for macOS, Linux, or Windows.

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.

pixel-plugin CLAUDE.md is an instructions file published in the GitHub repository willibrandon/pixel-plugin (302 stars, last pushed 10mo ago), licensed MIT. It adds 2,199 tokens to every session, about $0.0110 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
