  • Works in 3 steps: ツール呼び出しを追跡 - セッション内のツール呼び出しをカウント → 閾値検出 - 設定可能な閾値で提案（デフォルト：50回） → 定期的なリマインダー - 閾値後25回ごとにリマインド

What it does

Strategic Compact is an agent skill from affaan-m/ECC. 任意の自動コンパクションではなく、タスクフェーズを通じてコンテキストを保持するための論理的な間隔での手動コンパクションを提案します。

Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.

Example prompts

  • “/strategic-compact”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. ツール呼び出しを追跡 - セッション内のツール呼び出しをカウント
  2. 閾値検出 - 設定可能な閾値で提案（デフォルト：50回）
  3. 定期的なリマインダー - 閾値後25回ごとにリマインド

What it can do on your machine

Read from SKILL.md and the folder at commit 2d515e4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • x.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Strategic Compact loads about 434 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 68 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~21
When it runs · the whole SKILL.md, loaded when a task matches
~434

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

任意の自動コンパクションではなく、タスクフェーズを通じてコンテキストを保持するための論理的な間隔での手動コンパクションを提案します。

Strategic Compactスキル

任意の自動コンパクションに依存するのではなく、ワークフローの戦略的なポイントで手動の/compactを提案します。

なぜ戦略的コンパクションか？

自動コンパクションは任意のポイントでトリガーされます：

  • 多くの場合タスクの途中で、重要なコンテキストを失う
  • タスクの論理的な境界を認識しない
  • 複雑な複数ステップの操作を中断する可能性がある

論理的な境界での戦略的コンパクション：

  • 探索後、実行前 - 研究コンテキストをコンパクト、実装計画を保持
  • マイルストーン完了後 - 次のフェーズのために新しいスタート
  • 主要なコンテキストシフト前 - 異なるタスクの前に探索コンテキストをクリア

仕組み

suggest-compact.jsスクリプトはPreToolUse（Edit/Write）で実行され：

  1. ツール呼び出しを追跡 - セッション内のツール呼び出しをカウント
  2. 閾値検出 - 設定可能な閾値で提案（デフォルト：50回）
  3. 定期的なリマインダー - 閾値後25回ごとにリマインド

フック設定

プラグインとしてインストール済みの場合：設定は不要です。プラグインの hooks/hooks.json が既に suggest-compact.js を登録しています（フック ID pre:edit-write:suggest-compact、standard と strict フックプロファイルで有効）。下のブロックを ~/.claude/settings.json にコピーしないでください — プラグインインストールでは ~/.claude/scripts/ は存在せず、プラグインフックを重複させると二重実行になります。

手動インストール（./install.sh）の場合、~/.claude/settings.json に追加：

json
{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Edit",
        "hooks": [{ "type": "command", "command": "node ~/.claude/scripts/hooks/suggest-compact.js" }]
      },
      {
        "matcher": "Write",
        "hooks": [{ "type": "command", "command": "node ~/.claude/scripts/hooks/suggest-compact.js" }]
      }
    ]
  }
}

設定

環境変数：

  • COMPACT_THRESHOLD - 最初の提案前のツール呼び出し（デフォルト：50）

ベストプラクティス

  1. 計画後にコンパクト - 計画が確定したら、コンパクトして新しくスタート
  2. デバッグ後にコンパクト - 続行前にエラー解決コンテキストをクリア
  3. 実装中はコンパクトしない - 関連する変更のためにコンテキストを保持
  4. 提案を読む - フックはいつを教えてくれますが、するかどうかは自分で決める
