Ultra-compressed communication mode. Cuts token usage ~75% by dropping filler, articles, and pleasantries while keeping full technical accuracy. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman.

Generate multiple radically different interface designs for a module using parallel sub-agents. Use when user wants to design an API, explore interface options, compare module shapes, or mentions "design it twice".

厳格な診断ループで、ハードなバグやパフォーマンスの後退に対処します。再現→最小化→仮説立案→計装→修正→回帰テスト。ユーザーが「これを診断して」「これをデバッグして」と言ったとき、バグを報告したとき、何かが壊れている・例外を投げている・失敗していると言ったとき、またはパフォーマンスの後退を説明したときに使用します。

Edit and improve articles by restructuring sections, improving clarity, and tightening prose. Use when user wants to edit, revise, or improve an article draft.

Claude Codeのフックを設定し、危険なgitコマンド（push、reset --hard、clean、branch -Dなど）が実行される前にブロックします。ユーザーが破壊的なgit操作を防止したい場合、gitの安全フックを追加したい場合、またはClaude Codeでのgit push/resetをブロックしたい場合に使用します。

ユーザーの計画や設計について、決定木の各分岐を解決しながら、相互理解に達するまで執拗に質問を続けます。ユーザーが計画をストレステストしたい、設計について詰められたい、または「grill me」と言った場合に使用します。

Grilling session that challenges your plan against the existing domain model, sharpens terminology, and updates documentation (CONTEXT.md, ADRs) inline as decisions crystallise. Use when user wants to stress-test a plan against their project's language and documented decisions.

Compact the current conversation into a handoff document for another agent to pick up.

コードベース内の深化の機会を見つけます。CONTEXT.mdのドメイン言語とdocs/adr/の決定事項に基づきます。ユーザーがアーキテクチャを改善したい、リファクタリングの機会を見つけたい、密結合モジュールを統合したい、またはコードベースをよりテスト可能でAIがナビゲートしやすくしたい場合に使用します。

Migrate test files from `as` type assertions to @total-typescript/shoehorn. Use when user mentions shoehorn, wants to replace `as` in tests, or needs partial test data.

Search, create, and manage notes in the Obsidian vault with wikilinks and index notes. Use when user wants to find, create, or organize notes in Obsidian.

Build a throwaway prototype to flesh out a design before committing to it. Routes between two branches — a runnable terminal app for state/business-logic questions, or several radically different UI variations toggleable from one route. Use when the user wants to prototype, sanity-check a data model or state machine, mock up a UI, explore design options, or says "prototype this", "let me play with it", "try a few designs".

ユーザーが会話形式でバグや問題を報告し、エージェントがGitHubのIssueを作成するインタラクティブなQAセッション。背景でコードベースを探索し、コンテキストやドメイン言語を取得します。ユーザーがバグ報告、QA、会話形式でのIssue作成を希望する場合、または「QAセッション」に言及した場合に使用します。

ユーザーとのインタビューを通じて小さなコミット単位の詳細なリファクタリング計画を作成し、それをGitHub Issueとして登録します。ユーザーがリファクタリングの計画を立てたい場合、リファクタリングRFCを作成したい場合、またはリファクタリングを安全な段階的ステップに分割したい場合に使用します。

Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes — Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/PRD asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to "review since X".

Create exercise directory structures with sections, problems, solutions, and explainers that pass linting. Use when user wants to scaffold exercises, create exercise stubs, or set up a new course section.

Sets up an `## Agent skills` block in AGENTS.md/CLAUDE.md and `docs/agents/` so the engineering skills know this repo's issue tracker (GitHub or local markdown), triage label vocabulary, and domain doc layout. Run before first use of `to-issues`, `to-prd`, `triage`, `diagnose`, `tdd`, `improve-codebase-architecture`, or `zoom-out` — or if those skills appear to be missing context about the issue tracker, triage labels, or domain docs.

現在のリポジトリに、Huskyのpre-commitフックをlint-staged（Prettier）、型チェック、テストとともに設定します。ユーザーがpre-commitフックを追加したい、Huskyをセットアップしたい、lint-stagedを設定したい、またはコミット時のフォーマット/型チェック/テストを追加したい場合に使用します。

テスト駆動開発のレッド・グリーン・リファクタリングループ。ユーザーがTDDを使って機能を構築したりバグを修正したい場合、「レッド・グリーン・リファクタリング」に言及した場合、統合テストを希望する場合、またはテストファースト開発を依頼した場合に使用します。

Teach the user a new skill or concept, within this workspace.

Break a plan, spec, or PRD into independently-grabbable issues on the project issue tracker using tracer-bullet vertical slices. Use when user wants to convert a plan into issues, create implementation tickets, or break down work into issues.

Turn the current conversation context into a PRD and publish it to the project issue tracker. Use when user wants to create a PRD from the current context.

Triage issues through a state machine driven by triage roles. Use when user wants to create an issue, triage issues, review incoming bugs or feature requests, prepare issues for an AFK agent, or manage issue workflow.

Extract a DDD-style ubiquitous language glossary from the current conversation, flagging ambiguities and proposing canonical terms. Saves to UBIQUITOUS_LANGUAGE.md. Use when user wants to define domain terms, build a glossary, harden terminology, create a ubiquitous language, or mentions "domain model" or "DDD".

Create new agent skills with proper structure, progressive disclosure, and bundled resources. Use when user wants to create, write, or build a new skill.

Shape an article as a journey of beats, choose-your-own-adventure style. The user picks a starting beat from the raw material, you write only that beat, then offer options for where to pivot next, beat by beat, until the article reaches a natural end. Use when the user has raw material and wants to assemble it as a narrative rather than an argument.

Grilling session that mines the user for fragments — heterogeneous nuggets of writing (claims, vignettes, sharp sentences, half-thoughts) — and appends them to a single document as raw material for a future article. Use when the user wants to develop ideas before imposing structure, or mentions "fragments", "ideate", or "raw material" for writing.

Take a markdown file of raw material and shape it into an article through a conversational session — drafting candidate openings, growing the piece paragraph by paragraph, arguing about format (lists, tables, callouts, quotes) at each step. Use when the user has a pile of notes, fragments, or a rough draft and wants help turning it into something publishable.

Tell the agent to zoom out and give broader context or a higher-level perspective. Use when you're unfamiliar with a section of code or need to understand how it fits into the bigger picture.
