What it does

Diagnose why invoiced revenue is not becoming cash by aging receivables, identifying customer exposure, separating disputes and payment commitments, and prioritizing evidence-based collection actions. Use when overdue invoices or uncertain collections threaten cash planning; do not use for statutory accounting, legal debt enforcement, or automatic customer contact.

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# 売掛金・回収管理
10
11請求済み売上が現金化されない原因を、請求書単位の残高、経過日数、顧客集中、紛争、支払約束、資金への影響に分け、回収の確認順序と次の行動を作る。これは運営上の回収管理であり、会計上の貸倒判定、債権の法的有効性、強制回収の助言ではない。

13## 進め方
14
151. 最初に [インテークと判断方法](references/intake-and-method.md) を読み、請求書、入金、契約、検収、支払約束、紛争記録を質問より先に確認する。顧客名は匿名IDにし、不要な連絡先・口座・認証情報を収集しない。
162. 基準日、単一通貨、請求・入金の対象範囲を固定する。請求額、入金額、支払期日、約束日、紛争状態を confirmed、reported、estimated、unknown に区別し、unknown をゼロや回収不能へ置き換えない。
173. [計算モデル](references/calculation-model.md) に従って匿名化JSONをスキル外に作り、スキルのルートで python3 scripts/analyze_receivables.py <input.json> を実行する。年齢表、顧客別残高、明示された支払約束、資金影響を確認する。
184. 回収優先順位は、金額だけでなく、期限超過、約束不履行、紛争、顧客集中、契約・検収の未解決、相手先の支払手続、資金バッファへの影響で決める。根拠のない回収確率や一律の督促スコアを作らない。
195. [報告書形式](references/report-format.md) で、確定残高と不明残高、年齢表、支払約束、顧客別露出、資金の谷、内部確認、外部連絡案を分ける。各行動に担当、期限、必要資料、停止・エスカレーション条件を置く。
20
21## 判断上の制約
22
23- issued、due、overdue、disputed、promised、collected を混同しない。請求済みでも検収・契約条件が未解決なら、単純な督促より先に原因を確認する。
24- 確認済みの支払約束だけを短期資金計画へ加える。申告・推定の入金は別表示し、全売掛金を将来現金として扱わない。
25- 入金遅延日数は回収不能の判定ではない。法域、契約、倒産、時効、貸倒、税務処理が判断を左右する場合は、当日の権威ある一次情報または専門家を確認する。

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.

≈120
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
1,930
on trigger
The instruction body and 4 supporting files, read only when the skill fires.
1.0%
of a 200k window
Ten skills this size would take about 10% of the window before you open a file.
050k100k150k200k context window

2k 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

5 files, 18.7 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.md3.3 kB
  • references/calculation-model.md2.1 kB
  • references/intake-and-method.md1.6 kB
  • references/report-format.md1.2 kB
  • scripts/analyze_receivables.py10.5 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 5 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.

# Accounts Receivable Control · 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/accounts-receivable-control/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/accounts-receivable-control" ] && { [ ! -e .claude/skills/accounts-receivable-control ] || { mv .claude/skills/accounts-receivable-control "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/accounts-receivable-control" .claude/skills/ && echo "Installed .claude/skills/accounts-receivable-control"
On Windows, or any OS with Node 20+
npx mcprush@latest skill add ficilcom/accounts-receivable-control

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/accounts-receivable-control/ 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/accounts-receivable-control/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/accounts-receivable-control" ] && { [ ! -e ~/.claude/skills/accounts-receivable-control ] || { mv ~/.claude/skills/accounts-receivable-control "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/accounts-receivable-control" ~/.claude/skills/ && echo "Installed ~/.claude/skills/accounts-receivable-control" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/accounts-receivable-control/ 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.

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.
