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.
npx agentmods add instructions/akiojin/unity-mcp-server/agents-mdgit clone --depth 1 https://github.com/akiojin/unity-mcp-serverWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00224 | $0.00224 |
| Opus 5 | $0.00112 | $0.00112 |
| Sonnet 5 | $0.00045 | $0.00045 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
unity-mcp-server 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
@CLAUDE.md
Codex
- すべての shell コマンドは
bash -lcとworkdir指定で実行する - 検索は
rg/rg --filesを最優先で利用する - 小さな単一ファイル変更は
apply_patchを使い、生成物や大規模変更は別手段にする - 既存のユーザー変更を戻したり
git reset --hardなど破壊的操作は行わない - 返答は簡潔にまとめ、変更箇所は
path:line形式で示し、自然な次の行動があれば提案する - 報告だけで終わらず、必ず改善提案か次に取るべき自分の行動指針を含める
- 実行可能な作業は自分で完了させ、ユーザーに押し付けない
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.
