Synthesizes the current conversation and codebase understanding into a spec document, without interviewing. Use when the user asks to "write a spec", "turn this into a spec", "specにして", or after an interview reaches shared understanding.

A relentless one-question-at-a-time interview that sharpens a plan, decision, or idea until shared understanding is reached — not limited to software. Use when the user wants requirements or a decision clarified before acting, wants to stress-test their thinking, or asks to "grill me", "詰めて", "brainstorm this".
Executes an implementation plan or agreed work by orchestrating fresh subagents — one implementer per task, a reviewer between tasks — while the main model plans, briefs, and evaluates without writing code itself. Use when the user asks to "implement the plan", "start implementation", "実装して", or hands over a plan or spec to execute.
A feedback-loop-first discipline for diagnosing hard bugs and performance regressions. Use when the user reports something broken, throwing, failing, flaky, or slow, or asks to "diagnose", "debug this", "原因を調べて".
Builds a clearly-marked throwaway prototype to answer a design question before committing to an implementation. Use when the user wants to sanity-check whether logic or a state model feels right, explore what a UI should look like, or asks to "prototype this", "試作して".
Creates an Architecture Decision Record for a decision that is hard to reverse, surprising without context, and the result of a real trade-off. Use when such a decision has just been made, or the user asks to "record this decision", "ADRにして", or mentions decision records.
Reviews the diff since a fixed point along two axes run as parallel subagents — Spec (does the change match what was asked?) and Standards (repo conventions plus a code-smell baseline) — and reports them side by side. Use when the user asks to review a branch, work-in-progress changes, a diff, or "review since X".

Turn what's already been discussed into a spec. Do not interview the user — this skill synthesizes, it doesn't gather. If understanding of the problem is still thin, suggest /grill first and stop.
<actor>, I want <feature>, so that <benefit>." Cover the feature extensively.Leave out file paths and code snippets — they go stale fast. Exception: a snippet from a prototype that encodes a decision more precisely than prose (a state machine, reducer, schema, type shape) can be inlined under the relevant decision, trimmed to the decision-rich part and noted as prototype-derived.
Check .claude/engineering.local.md for a specs: key in its frontmatter — a path, or none to skip saving. If the file doesn't exist, ask once where (or whether) to save this spec, accept "don't save" as an answer, and mention /setup-engineering for making the choice permanent. Never write specs into CLAUDE.md or AGENTS.md.
