設定バンドルを更新する

で設定を編集agentcore.jsonし、再デプロイします。CLI は既存のバンドルを検出し、正しい を使用して新しいバージョンparentVersionIdsを自動的に作成します。

# Edit the bundle configuration in agentcore.json (change model_id, system prompt, etc.)
# Then redeploy to create a new version:
agentcore deploy

# After deploying, confirm a new immutable version was created:
agentcore cb versions --name MyBundle

# Inspect what changed between two versions (get IDs from `cb versions`):
agentcore cb diff --name MyBundle --from <v1> --to <v2>

モデル ID の変更を更新します。
