Document codebase as-is via parallel sub-agents. Use when researching how code works, mapping architecture, or answering questions about existing systems. Auto-detects thoughts/ directory — if present, integrates historical context and syncs; if absent, skips those steps.
Create the Questions artifact before codebase research, design, planning, or implementation. Use for feature tickets, architecture changes, unclear code work, CRISPY/QRSPI Questions phase, or when the agent needs to define code-answerable unknowns and human questions before researching or planning.
Create a concise Design Concept artifact after questions and codebase research are available. Use for CRISPY/QRSPI Design phase, architecture alignment, feature design discussion, or turning current-state research into a small human-reviewable proposed shape before detailed planning.
Create an interface-first Structure Outline before detailed planning or implementation. Use for CRISPY/QRSPI Structure Outline phase, vertical planning, method signatures, type contracts, API/component boundaries, or converting an accepted design concept into end-to-end slices with verification checkpoints.
Create comprehensive handoff documents for transferring work to another agent session. Use when the user requests to create a handoff, end a session, or document work-in-progress for future continuation.
Create detailed implementation plans through interactive research and iteration. Use when starting a new feature or ticket that needs a comprehensive technical plan. Saves plans to the repo-appropriate plans location and emits Personal Knowledge events when applicable.
個人腦力激盪教練。用結構化技巧逼出你自己的想法，而非替你產生點子。 僅在使用者明確說出「腦力激盪」或「brainstorm」時觸發，其他模糊說法（幫我想想、 想不出辦法、有什麼可能）不觸發。 角色：Claude 是 coach，用 probing question 引導，不是 idea generator。
通用 skill 自我進化工具。當任何 skill 執行後使用者有修正、抱怨、或說「少了什麼」， 且能確認是可重複的 skill 規則缺口時，才在 response 末尾輸出 <<GAP skill-name: 一句話描述缺口>>， Stop hook 自動寫入 signal-queue.md。 主動觸發：「improve」「skill 改進」「improve skill」「修正 skill」「更新 skill 規則」 「skill 有缺口」「skill 漏掉了」「self-improve」「自我進化」「skill 學習」。 初始化：「improve init」批量為選定 skill 生成 Signal Collection 區塊（供人工審核）。
