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 | $0.00242 | $0.00242 |
| Opus 5 | $0.00121 | $0.00121 |
| Sonnet 5 | $0.00048 | $0.00048 |
| Haiku 4.5 | $0.00024 | $0.00024 |
Grade A, and why
arcadeactions AGENTS.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.
What it actually says
Read before coding:
- Follow docs in order:
docs/prd.md->docs/api_usage_guide.md->docs/testing_guide.md. - Refer to
/docsfor any context or patterns before implementation.
Design priorities (in order): dev experience, simplicity, fit with underlying APIs, API quality, testability, best practices.
Structure/complexity:
- Keep modules around ~500 lines and functions around ~20 cyclomatic complexity.
- Split modules/functions intelligently to avoid high complexity or large files.
- If splitting would reduce clarity, ask for a decision before doing it.
Hard rules:
- Avoid dataclasses unless there is a clear, documented benefit.
- Avoid runtime type/attribute checks (hasattr/getattr/isinstance/EAFP-with-pass).
- No silent EAFP;
except AttributeError: passis forbidden. - Use
uv run python(never plainpython). - Define and use explicit Protocols/adapters for sprite/window/action interfaces; validate at boundaries instead of ad-hoc attribute probes.
Dependency/testability:
- Accept dependencies via constructors; avoid hidden instantiation inside methods.
- Avoid circular dependencies.
- Prefer composition over inheritance for dependencies.
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.

arcadeactions AGENTS.md is an instructions file published in the GitHub repository bcorfman/arcadeactions (5 stars, last pushed 8d ago), licensed MIT. It adds 242 tokens to every session, about $0.0012 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.
