What it does

プロジェクトにおけるAI駆動開発の実践状況を、「AI駆動開発 実践力カタログ」評価基準に基づいて確認・採点し、Excelへ出力する。確認済みの項目は state ファイルに保存し、次回評価時は原則再確認しない。「AI駆動開発の実践度を診断して」「実践力カタログで評価して」「前回の続きから評価して」等で使う。

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
11## これは何をするスキルか
12
13プロジェクトにおけるAI駆動開発の実践状況を、references/criteria.json の評価基準(0/25/50/75/100点の5段階、全20項目)に基づいて確認し、点数化した上で、既存の「AI駆動開発 実践力カタログ」Excelへ出力する。
14
15確認済みの項目はGit管理されたstateとして保存され、次回評価時は原則としてスキップする。同じ質問を評価のたびに繰り返さないための仕組みである。
16
17## 役割分担の原則
18
19- **AIが担当するもの**:確認結果の意味判断、リポジトリ調査、ユーザーへの質問、「推奨対応」文章の作成。
20- **スクリプトが担当するもの**:JSONの生成・更新、点数計算、整合性チェック、Excel出力。点数判定やExcel転記をAIが目測で行ってはならない。必ず scripts/ 配下のスクリプト経由で行う。
21- **check-results.json を直接編集しない。** 更新は必ず update_check_result.py 経由で行う。
22
23## 評価処理の全体フロー
24
251. python scripts/get_assessment_state.py で現在の評価状態を取得する。
262. 返された items[].checks[] のうち status が unconfirmed または needs_recheck の項目を、次回の確認対象として特定する(confirmed と not_applicable は原則スキップ)。
273. 確認対象のうち、リポジトリ内のコード・ドキュメント・設定ファイル等の調査で判断できるものは、AI自身が調査して判断する。ユーザーへ質問する前に、まずこの調査を行うこと。

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.

≈80
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
17,670
on trigger
The instruction body and 25 supporting files, read only when the skill fires.
8.9%
of a 200k window
Ten skills this size would take about 89% of the window before you open a file.
050k100k150k200k context window

17.8k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

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.

It asks the agent to write files, using whatever file access your client already has. Whether it reaches the network is not declared.

What it asks for
Writes filesyes
Network accessnot declared

Read from the allowed-tools line of this skill’s own SKILL.md. It also asks for Bash, which could do either, so what is not named there is not ruled out. 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

The download carries 26 of the 28 files in its source folder; the list here names 26 files, 97.9 kB on disk. Mostly text — the instructions the model reads — with 14 scripts in it that your client would run only if the instructions tell it to. The other 2 are not in the download — listed after these, with why.

Not in the download

Too deep is past six folders and not carried is a type a skill download does not hold. Marked read: its SKILL.md or scripts name the file, so without it the skill works only in part. Take them from its source.

What is not in it

A skill installs nothing and depends on nothing: it is a folder your client reads. This one carries 14 scripts beside the text, so the download is 26 files — not the whole of its source: 2 files are left out, and the skill reads 2 of them. They are listed under the files, with why. The MIT licence covers the templates and examples as well as the instructions.

Install

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

# AI Development Assessment · 17.8k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/ai-development-assessment/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/ai-development-assessment" ] && { [ ! -e .claude/skills/ai-development-assessment ] || { mv .claude/skills/ai-development-assessment "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/ai-development-assessment" .claude/skills/ && echo "Installed .claude/skills/ai-development-assessment"

npx mcprush@latest skill add wss-m-nagata/ai-development-assessment

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/ai-development-assessment/ 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/ai-development-assessment/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/ai-development-assessment" ] && { [ ! -e ~/.claude/skills/ai-development-assessment ] || { mv ~/.claude/skills/ai-development-assessment "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/ai-development-assessment" ~/.claude/skills/ && echo "Installed ~/.claude/skills/ai-development-assessment" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/ai-development-assessment/ 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. Not in this download: 2 files of its source, 2 of them read by its SKILL.md or scripts (the full list, and why). Take them from its source.

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.
