In plain words

Why use it?
It gives agents project-specific rules so they make fewer unnecessary changes and handle reviews and tests consistently.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md; $skill-name invocation.

This is j5ik2o/event-store-adapter-js's own configuration. It tells Codex and OpenCode how to work on event-store-adapter-js itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything event-store-adapter-js configures →

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

event-store-adapter-js 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 6d 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.

GitHub Pull Request のモニタリング

PR を作成したらモニタリングすること。 PRを監視・対応する際は、以下をすべて守ること。

  • コメントへの対応
    • 監視待機中も定期的に新しいコメントが投稿されていないか確認する。
    • すべてのコメント(トップレベル、インラインなど)を無視せず、必ず適切に対処する。
    • 対処方法としては、コメントの指摘内容をコードに反映した上でその旨をコメントに返信する。コメントの指摘内容が妥当でない場合は、非対応である旨をコメントに返信する。
  • テストカバレッジ
    • カバレッジエラーを無視せず、必ず適切に対処する。(解決方法としてcodecov.ymlを変更しないこと)
  • マージ準備
    • マージに必要な作業はすべて実施する。
  • マージの実行
    • マージ操作自体は実行せず、人間に委譲する。

$grill-me 実行時の作業判断

$grill-me で実施すべき作業内容が決まったら、その規模に応じて以下のいずれかを選択すること。

軽い作業の場合

  • プランモードを用いず、そのまま作業に着手する。

複雑または重い作業の場合

  • $openspec-propose を呼び出して change を作成する。
  • 単一の change では大きすぎる場合は、複数の change に分割する。
  • 分割した場合は、以下の成果物を生成すること。
    • docs/plan/${date}_${epic-name}.md
      • 各 change の概要をまとめたインデックスドキュメント
    • 各 change ファイル
      • 分割した change それぞれを個別に生成

Read these rules before implementing:

  • COMMON.md
  • .agents/rules/**/*.md

These guidelines are working if: fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.

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.
