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 | $0.00046 | $0.00289 |
| Opus 5 | $0.00023 | $0.00144 |
| Sonnet 5 | $0.00009 | $0.00058 |
| Haiku 4.5 | $0.00005 | $0.00029 |
Grade A, and why
setup-pixel 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 4d 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.
What it actually says
Set up pixel-art tooling
Run the core doctor and inspect the engine, sprite and tileset formats, Aseprite/Pixelorama/Tiled availability, OS/architecture, existing pixel MCP host, output paths, and current worktree state.
The MCP option is MIT-licensed willibrandon/pixel-mcp at the immutable descriptor commit and requires an existing Aseprite-compatible executable workflow. Pixelorama and Tiled are non-MCP alternatives: compare them when Aseprite is unavailable, licensing or cost matters, or direct automation is unnecessary. Do not present non-MCP editors as active MCP servers.
Create pack plan pixel --project <root> --output <plan.json>. A local server executable requires an absolute path and matching SHA-256. Show exact actions, downloads, licenses, permissions, backups, expiry, rollback, and digest; wait for confirmation before apply. Finish with pack doctor and a read-only capability check.
Generated sprites stay separate from source art until transparency, dimensions, pivot/baseline, palette, loop continuity, engine import, and human visual review pass. Only one pixel/Aseprite MCP host may be active.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

setup-pixel is a skill published in the GitHub repository frabcd/codex-ai-game-studio (8 stars, last pushed 3d ago), licensed MIT. It adds 46 tokens to every session and 289 once invoked, about $0.0002 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 2026-08-31.

watch
File sentinel that monitors the working directory for changes and marker comments, then auto-triggers appropriate skills. Poll-based via git diff against the last scan commit. Writes intake items for batch processing and routes marker actions through /do. Use for automatic reactions to file changes; do NOT use for…
review
5-pass structured code review — correctness, security, performance, readability, consistency.
marshal
Meta-orchestrator that takes any direction — broad, specific, or vague — and autonomously chains skills and context into actionable work. Gathers context from codebase, docs, and memory. Only asks the user when it genuinely cannot proceed. Single-session orchestrator.

Markdown-first knowledge base where the LLM acts as librarian. Ingests raw sources, compiles and interlinks topic files, self-maintains an index. No vector DB or embeddings required -- uses LLM-native navigation over structured markdown up to 400K words.
