What it does

ユーザーの計画・決定・アイデアについて容赦なく問い詰める(grillする)。ユーザーが自分の考えを検証(stress-test)したいときや、'grill'関連のトリガーフレーズを使ったときに使用する。

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

10共通の理解に達するまで、容赦なくユーザーにインタビューしてください。これを設計ツリーとして捉えます — すべての決定は、そこにぶら下がる次の決定へと枝分かれしていきます。
11
12ツリーは**ラウンド**単位で進めます。**フロンティア**とは、前提となる決定がすでに確定している決定すべて — つまり、まだ聞いていない答えを推測せずに今すぐ聞ける質問のことです。ラウンドは既定でフロンティアのうち1問だけです。あなたの推奨する回答を添えて質問し、ユーザーの回答を待ってから次のラウンドに進みます。複数の質問を一度に並べると、ユーザーが全体を把握しきれず回答が雑になります。
13
14次のいずれかに該当する場合に限り、ラウンドをフロンティア全体(各質問に番号を振り、それぞれ推奨回答を添える)に広げてよい:
15- ユーザーが「まとめて聞いて」のように明示的に指示した場合
16- 直近の複数ラウンドで、ユーザーの回答がほぼ一貫して推奨通りだった場合。この場合はまず「ここまで推奨通りの回答が続いていますが、残りはまとめて聞いてもよいですか?」と確認を取ってから広げる
17
18広げた後でも、推奨から外れる回答や認識のずれが出たら、次のラウンドから1問に戻す。
19
20ユーザーが回答するたびにツリーは組み替わります — 確定した決定がフロンティアを外側へ押し広げ、それに依存していた質問が解禁されます。フロンティアを再計算し、次のラウンドに進んでください。答えが「まだ未解決の質問」に依存する質問は、それより後まで解禁されません。
21
22**事実を突き止めるのはあなたの仕事であり、ユーザーの仕事ではありません。** フロンティアの質問に環境(ファイルシステム、ツールなど)から得られる事実が必要な場合は、サブエージェントを派遣して調べさせてください — 自分で調べられることをユーザーに尋ねないこと。ただしそこでブロックしないでください: 実行中の調査は「未確定の前提」なので、待つのはそのサブエージェントの報告に依存する質問だけです — 残りのフロンティアは今すぐ質問してください。**決定はユーザーのものです。**
23
24派遣したサブエージェントの報告は、ユーザーの操作とは無関係なタイミングで返ってきます。**すでに提示済みで未回答の質問がある間は、報告が届いたことを理由に語り始めないでください。** 報告は静かに読み取って理解に取り込むだけにとどめ、新たな説明や前置きを書き出さないこと — それをやると直前の質問が大量のテキストの下に埋もれ、ユーザーが何に答えればよいか見失います。報告内容を踏まえて今の質問自体を修正する必要がある場合(前提が崩れた、選択肢が増えた、推奨が変わったなど)に限り、その変更点を一言だけ添えたうえで、更新後の質問をメッセージの末尾に――他のどの内容よりも目立つ形で――再掲してください。報告が今の質問に影響しないなら、次にユーザーが回答してあなたの番が来るまで内容を保留し、そのとき初めて必要な範囲で触れます。

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈30
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
1,095
on trigger
The instruction body and 1 supporting file, read only when the skill fires.
0.56%
of a 200k window
Ten skills this size would take about 6% of the window before you open a file.
050k100k150k200k context window

1.1k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Small enough to keep loaded permanently without thinking about it.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

2 files, 4.5 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md4.4 kB
  • agents/openai.yaml0.1 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 2 files you can review in full before installing.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# Plan & Decision Stress Tester · 1.1k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/plan-decision-stress-tester/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/plan-decision-stress-tester" ] && { [ ! -e .claude/skills/plan-decision-stress-tester ] || { mv .claude/skills/plan-decision-stress-tester "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/plan-decision-stress-tester" .claude/skills/ && echo "Installed .claude/skills/plan-decision-stress-tester"

npx mcprush@latest skill add ryohma0510/plan-decision-stress-tester

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/plan-decision-stress-tester/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/plan-decision-stress-tester/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/plan-decision-stress-tester" ] && { [ ! -e ~/.claude/skills/plan-decision-stress-tester ] || { mv ~/.claude/skills/plan-decision-stress-tester "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/plan-decision-stress-tester" ~/.claude/skills/ && echo "Installed ~/.claude/skills/plan-decision-stress-tester" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/plan-decision-stress-tester/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where. It appears as grilling in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, plan-decision-stress-tester.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
