What it does

Compare products and services using contribution, capacity, demand evidence, downside scenarios, offer relationships, strategic fit, and exit gates. Use when deciding which offers to grow, repair, test, bundle, hold, or consider retiring; do not use as authorization to discontinue an offer or change customer commitments.

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.

11商品・サービスごとの利益と希少な提供能力の消費を揃え、伸ばす、直す、検証する、束ねる、終了を検討する対象を分ける。売上規模だけで判断せず、需要の証拠、戦略適合、顧客・契約への影響を別に扱う。

13## 進め方
14
151. [インテークと判断方法](references/intake-and-method.md)を読み、同じ期間・通貨・変動費範囲で商品別の売上、変動費、提供工数、需要証拠、戦略適合を集める。
162. 入力を confirmed、reported、estimated、unknown に分ける。需要、商品間関係、感度、退出制約まで判断する場合は advanced を選び、[判断ルール](references/decision-rules.md)を読む。共通費を根拠なく商品へ割り振らない。
173. [計算モデル](references/calculation-model.md)に従い匿名化JSONを作り、スキルのルートで python3 scripts/analyze_offer_portfolio.py <input.json> を実行する。
184. 貢献利益、利益率、提供1時間当たり貢献、能力消費、需要、シナリオ、商品間関係、戦略適合、退出ゲートを並べる。経済順位と判断シグナルを推奨や自動実行にしない。
195. [報告書形式](references/report-format.md)で grow、repair、test、bundle、hold、retire candidate を示し、必要な検証と再判断日を置く。

21## 判断上の制約
22
23- 過去売上だけで需要を推定せず、受注率、更新、待ち行列、失注理由、顧客要望を区別する。
24- 低利益でも入口商品、信頼形成、他商品の販売に効く場合がある。効果を証拠なしに利益へ足さず、別の戦略仮説として検証する。
25- 終了判断では既存契約、返金、移行、顧客連絡、ブランド影響を確認する。不明値をゼロへ置き換えない。

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.

≈100
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
1,925
on trigger
The instruction body and 5 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

6 files, 26.9 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.md2.6 kB
  • references/calculation-model.md1.9 kB
  • references/decision-rules.md1.5 kB
  • references/intake-and-method.md1.2 kB
  • references/report-format.md0.9 kB
  • scripts/analyze_offer_portfolio.py18.8 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.

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

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