What it does

Determine whether a bootstrapped business can afford its first employee by modeling fully loaded employment cost, cash buffer and runway, downside and delayed-start scenarios, and the earliest defensible hiring date. Use before opening a first role or committing to a first employee; do not use as legal, tax, payroll, or employment-law advice.

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# 最初の採用の資金余力
10
11最初の従業員を採用した後も、必要な現金バッファを維持して運営できるかを現金ベースで判定する。給与だけでなく、事業主負担、福利厚生、採用、一時的な設備・ソフトウェア、オンボーディング、生産性立上がり、管理時間、退職・解雇等の偶発的一時費用を分けて見積もる。結論は hire_now、conditional、defer、unaffordable、または重要情報が不明な indeterminate とし、最短開始月と実行条件を示す。これは採用判断の運営分析であり、雇用契約、支払能力、労務・税務・法務上の専門判断ではない。
12
13## 進め方
14
151. 最初に [インテーク](references/intake.md) を読み、提出済みの銀行残高、資金繰り、給与見積、採用計画を確認する。根拠は confirmed、reported、estimated、unknown に分け、unknown をゼロにしない。
162. 少なくとも base、downside、delayed を作る。base は根拠のある中心見通し、downside は回収遅延・売上低下・費用増など意思決定を変え得る不利な見通し、delayed は開始延期案とする。雇用開始月、既存事業の月次入出金、採用後の便益立上がりをそれぞれ明示する。
173. [計算モデルとJSON契約](references/calculation-model.md) を読み、必要最小限に匿名化した単一通貨のJSONをスキル外へ作る。賃金に会社負担を重複計上せず、各コストの現金支払時期を区別する。
184. スキルのルートで python3 scripts/calculate_affordability.py <input.json> を実行する。検証エラーを推測で埋めない。開始現金、最低バッファ、通常の入出金、または雇用コストの重要値が unknown なら、数値結論は indeterminate とし、不足情報を報告する。
195. [判断ルール](references/decision-rules.md) を読み、スクリプトの判定を事業上の便益、採用リードタイム、確認済みでない前提に結び付ける。開始月は、base と downside の両方でバッファを維持する最も早い月を基準にし、単なる希望開始日を「賄える」と扱わない。
206. [報告書形式](references/report-format.md) を読み、シナリオ比較、採用前後の現金、ランウェイ、総雇用コスト、便益回収、最短開始月、撤退条件、不確実性を利用者の言語で報告する。
21
22## 判断上の制約
23
24- minimum_cash_buffer は雇用コストではない。期末現金がバッファを下回ることと、現金が負になることを別々に扱う。予測期間内に割れなければ、未検証の将来まで安全だと断定しない。
25- 便益立上がりは、採用で直ちに売上が増えると仮定しない。採用効果は月次の現金便益として根拠・時期を示し、雇用コストと別表示する。便益が総コストを回収しない場合も隠さない。
26- 所得税源泉、社会保険、労働保険、福利厚生の法定要件、雇用区分、解雇・退職コストは法域・契約・時点に依存する。結論を変える場合だけ、当日の政府・公的機関等の権威ある一次情報を確認し、確認日と出典を記す。専門家の判断を代替しない。
27- conditional は条件を満たす前の採用承認ではない。必要な現金改善、根拠確認、採用開始日の再計算を、実行条件として具体化する。

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.

≈110
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
4,040
on trigger
The instruction body and 5 supporting files, read only when the skill fires.
2.1%
of a 200k window
Ten skills this size would take about 21% of the window before you open a file.
050k100k150k200k context window

4.2k 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.

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, 40.8 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.md4.4 kB
  • references/calculation-model.md5.0 kB
  • references/decision-rules.md2.4 kB
  • references/intake.md2.1 kB
  • references/report-format.md2.7 kB
  • scripts/calculate_affordability.py24.2 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.

# First Hire Affordability Calculator · 4.2k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/first-hire-affordability-calculator/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/first-hire-affordability-calculator" ] && { [ ! -e .claude/skills/first-hire-affordability-calculator ] || { mv .claude/skills/first-hire-affordability-calculator "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/first-hire-affordability-calculator" .claude/skills/ && echo "Installed .claude/skills/first-hire-affordability-calculator"

npx mcprush@latest skill add ficilcom/first-hire-affordability-calculator

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

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.
