Cursor Composer Task Delegate

🚀 cursor / composer-2.5-fast / feat/foo-bar / Add login form validation
これから:
1. pre-check (branch / cursor-agent) → 専用 worktree 作成
2. composer に実装委譲 (--write)
3. diff レビュー → cherry-pick → Plans.md 更新

× 「composer 2.5 で実装する流れですね、まず確認します」（中身のない前置き）
× 「Cursor を呼ぶ前に branch を見ます」 → bash → 「branch を確認しました」（言い換え）
× ★ Insight ──── Cursor の強みは…

  PROMPT="<task-description>
Purpose and why: <expected outcome and user need>
Owned paths and non-goals: <assigned files/modules and excluded work>
Definition of done: <observable conditions and required checks>
Contract and authorization references: <selected plan/spec paths and original user instruction or applicable approval record>
Available evidence: <observed state, prior attempts, findings and artifact paths>

Constraints:
- Choose the implementation method within the assigned scope. Other workers may be active; preserve their edits.
- Recover missing context from the supplied contracts and read-only inspection first. State minor assumptions; stop only the action that needs a material decision or missing authorization.
- Complete authorized reversible work without asking again. Inferred scope is not authorization for protected operations.
- Preserve required TDD and validation. After required checks pass, add checks only for new changes, failures, or unresolved concerns.
- Match existing code style and naming.
- Create exactly one git commit if your environment supports it; otherwise leave one dirty changeset for Lead auto-commit.
- Do not touch .claude-plugin/settings*, .claude/settings*, .eslintrc*, biome.json, tsconfig*.json.
- Return the result, decision reasons, changed paths, check commands/results and remaining limitations. A success claim alone is not evidence."
