think

think is a skill for Claude Code from thkt/dotclaude. It costs 82 tokens per session (4,021 once invoked), scanned A, original, MIT.

A design-planning workflow that compares at least two possible approaches, has them critiqued, and turns the surviving approach into a structured plan.

In plain words
What is it for?
Exploring solutions, checking the task’s desired outcome, reviewing related code and prior research, selecting a suitable existing module when one fits, and drafting a plan.
Why use it?
It helps avoid committing to the first idea and makes the reasoning behind a technical plan explicit before implementation begins.

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

think 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/think - 設計探索

2 つ以上の案を critic-design の批判にかけ、生き残った案だけを構造化 plan にまとめる。plan は templates/plan.md の骨格で下書きファイルに書き出し、会話でも返す。永続化は /issue が issue の Plan 節へ移設して行う。

入力

$ARGUMENTS でタスク説明と調査の文脈を受け取る。空なら AskUserQuestion でユーザーに確認する。先頭行をタスクのタイトルとして扱う。

Phase 1: Why の確立

.claude/OUTCOME.md を読む。存在しない場合は /outcome で生成する。Why は 3 点で構成し、タスクが Bug のときは 4 点目として原因を足す。誰が何に困っているか、何を成功とみなすか、なぜ今やるか、Bug なら原因は何か。困りごとには根拠を添える。原因は再現手順やログなど根拠とともに特定し、原因が未確定なら設計へ進まず /research に回す。戻ってきた調査レポートに 仮説ログ 節があれば、それを原因の根拠として読む。設計はこの Why が $ARGUMENTS と会話から読めてから始める。曖昧なまま仮置きせず、AskUserQuestion で詰める。

${CLAUDE_SKILL_DIR}/../../rules/conventions/DOCUMENTS.md に従い、関連 wiki・DR と原本の適用条件・状態を現在の要求へ照合する。必要な文書更新を今回の合意範囲へ含め、実装と同じ評価へ渡す。

Phase 2: 設計探索

案は、実在するコードと既存の調査に照らしてから作る。手順 1 から 4 は、案が 1 つも無い状態で終える。

  1. 関連コードを読む。タスク、issue、調査レポートのいずれかがモック画像を参照しているなら、その画像も Read で開く。テキスト側に記載が無いことを、その要素が存在しない根拠にしない
  2. タスクの語から小文字ハイフン区切りの slug を作る。${CLAUDE_SKILL_DIR}/../research/scripts/find-prior-research.ts docs/research research .claude/workspace/research を実行する。該当候補の path を読む。aliases は同内容の移行コピーを示し、異なる版は比較する。各箇所を ${CLAUDE_SKILL_DIR}/references/research-report-intake.md の表のとおり扱う。候補が 0 件なら調査レポートは無いものとして進む
  3. reference_module の候補を探す。対象は画面の組か layer の組が一致する既存モジュールで、ドメインは問わない。もっとも近い 1 つを選び、他は名前を控える。結果は kind (module/no-module/new-shape) と理由で控える。一致が無ければ新規である理由を控える
  4. ${CLAUDE_SKILL_DIR}/../scribe/scripts/find_wiki_rule.ts docs/wiki <slug> <触りそうなパス> --scene plan を実行し、matched と scenes のページを読む。決まりごとは unit の切り方と files の選び方を決めるので、分割の後に読むと割り直しになる
  5. 異なる視点 (動く最小解/構造と拡張性/開発体験) から 2 つ以上の案を生成する。独立した技術判断は 1 つの質問に束ねず、推奨とトレードオフを添えて別々に問う
  6. 案に critic-design を起動する。プロンプトにタスクのタイトルを一字一句そのまま含め、結果は { verdict: "GO" | "NO-GO", weaknesses: string[], actionable: string[] } の JSON オブジェクト 1 つで返させる
  7. NO-GO は blocker をその場で解消してから進む。生き残った設計をトレードオフの根拠とともにユーザーに提示し、承認を待つ
  8. 承認後、技術判断に DR が必要か問う

Phase 3: Plan 生成

承認された設計を unit へ実装順で分解する。unit は独立して実装できる成果 1 つ分。結果は PLAN_SCHEMA 相当の JSON へ直列化する。

{ test_command, reference_module, units: [{ id, goal, contract, files: string[], tests: [{ id, name }], seam }] }

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
