What it does

Organize how a contractor engagement actually operates against recognized factors - direction and control, work discretion, time and place constraints, remuneration character, exclusivity, substitutability, and equipment burden - preserving each factor's evidence state, sizing retroactive cost from user-supplied assumptions only, and testing which employment-like factors a proposed change actually removes.

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.

9# 業務委託と雇用の線引き
10
11業務委託として運用している関係の実態を要素ごとに整理し、雇用的と観測された要素、未観測の要素、利用者が置いた前提での遡及コスト規模、是正案が実際に消す要素を示す。該当性の判定ではなく、行政・司法の判断を代替するものでもない。
12
13## 進め方
14
151. 最初に [インテークと方法](references/intake-and-method.md) を読み、契約形式、月額、経過月数、残り見込み月数と、実際の働き方を確認する。氏名、保護属性、個人が特定できる情報を入力へ含めない。
162. [判断要素の定義と観測例](references/classification-factors.md) に沿って、7つの要素を1件ずつ観測する。契約書の文言ではなく運用の実態から埋め、契約書との食い違いは食い違いとして記録する。
173. 観測を independent、mixed、employment_like、unknown に分け、証拠を confirmed、reported、estimated、unknown に分ける。確認していない要素を独立的と推定して埋めない。
184. [計算モデル](references/calculation-model.md) に従いスキル外へ匿名化JSONを作り、スキルのルートで python3 scripts/assess_engagement_structure.py <input.json> を実行する。遡及コストと是正案を見る場合は analysis_mode を advanced にする。
195. 是正案は、どの雇用的要素を実際に消すかで評価する。全案を実行しても残る要素と、その要素についての専門家確認の要否を確認する。
206. [報告書形式](references/report-format.md) で、要素別の観測、遡及コストと置いた前提、是正案と事業への影響、次の行動を示す。専門家へ確認すべき論点は期限付きで分けて書く。
21
22## 判断上の制約
23
24- 要素の多数決や合計点で結論を出さない。要素ごとの観測状態と証拠状態を保持したまま報告する。
25- 該当性を判定せず、行政・司法の判断を代替しない。判断が必要な論点は社会保険労務士または弁護士へ確認する条件として示す。
26- 遡及コストは利用者が置いた前提の算術であり、保険料額、税額、割増賃金額の決定ではない。前提の値と根拠を必ず併記する。
27- 契約書の文言変更だけを是正として扱わない。運用が変わらなければ要素の観測状態は変わらない。

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.

≈210
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
3,615
on trigger
The instruction body and 5 supporting files, read only when the skill fires.
1.9%
of a 200k window
Ten skills this size would take about 19% of the window before you open a file.
050k100k150k200k context window

3.8k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Middling. Fine to keep on in a project where you use it weekly, worth unloading in one where you never do.

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

6 files, 29.4 kB on disk. Mostly text — the instructions the model reads — with 1 script in it that your client would run only if the instructions tell it to.

  • SKILL.md3.9 kB
  • references/calculation-model.md3.2 kB
  • references/classification-factors.md3.1 kB
  • references/intake-and-method.md3.2 kB
  • references/report-format.md1.9 kB
  • scripts/assess_engagement_structure.py14.1 kB
What is not in it

A skill installs nothing and depends on nothing: it is a folder your client reads. This one carries 1 script beside the text, so the bundle is 6 files you can review in full before installing. 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.

# Contractor vs Employment Structuring · 3.8k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/contractor-vs-employment-structuring/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/contractor-vs-employment-structuring" ] && { [ ! -e .claude/skills/contractor-vs-employment-structuring ] || { mv .claude/skills/contractor-vs-employment-structuring "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/contractor-vs-employment-structuring" .claude/skills/ && echo "Installed .claude/skills/contractor-vs-employment-structuring"

npx mcprush@latest skill add ficilcom/contractor-vs-employment-structuring

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/contractor-vs-employment-structuring/ 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/contractor-vs-employment-structuring/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/contractor-vs-employment-structuring" ] && { [ ! -e ~/.claude/skills/contractor-vs-employment-structuring ] || { mv ~/.claude/skills/contractor-vs-employment-structuring "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/contractor-vs-employment-structuring" ~/.claude/skills/ && echo "Installed ~/.claude/skills/contractor-vs-employment-structuring" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/contractor-vs-employment-structuring/ 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 contractor-or-employment-structuring in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, contractor-vs-employment-structuring.

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.
