What it does
The skill functions as a market sizing and competitive intelligence expert. It aims to convert assumptions into data-driven TAM, SAM, and SOM analysis, maps the competitive landscape, and identifies beachhead markets and expansion opportunities with market sizing data.
How it works
- Applies a Market Sizing Pyramid framework combining TAM/SAM/SOM analysis (top-down and bottom-up) with competitive landscape mapping and beachhead market selection.
- Introduces a project directory setup step to organize outputs under a .strategy/ foundation-strategy structure.
- Performs Intelligent Context Detection to reuse prior validation data if available, otherwise prompts for fresh data collection.
- Provides two data collection approaches: Structured Questions (with 4 MC questions and 5 open-ended questions) or Conversational input, then proceeds to TAM/SAM/SOM analysis.
- Guides through TAM analysis using Top-Down, Bottom-Up, and Value Theory methods, with explicit output requirements (conservative, likely, aggressive estimates, methodology, assumptions, risks).
- Guides SAM calculation by applying ICP constraints (geography, verticals, company size, product limitations) and computing SAM = TAM × ICP-match percentage, with explanation and ICP definition.
- Guides SOM estimation over 3-5 years, offering market share benchmarks and revenue projections (SOM × ARPU), plus 2–3 paragraph assumptions.
- Presents a Competitive Landscape section including Direct, Indirect, and Substitute analyses, plus Porter's Five Forces with a structured table.
When to use it
- Use when seeking to quantify market opportunity and plan entry strategy for a new product or service.
- Use when you have or want to collect structured market and competitive data to support business decisions and beachhead market selection.
What it can touch
- Tools declared: claude-code
- Touchpoints include: project directory creation, foundational strategy outputs under .strategy/foundation-strategy/, and generation of TAM/SAM/SOM analyses, competitive landscape data, ICP definitions, and market-entry strategies as outputs.
Caveats
- The skill requires data gathering steps and may depend on user-provided inputs or flagged prior outputs; outcomes depend on data quality.
- It uses a structured approach with explicit output requirements for TAM, SAM, and SOM analyses and assumes standard market sizing methodologies.
# Market Opportunity Analyzer You are an expert market analyst specializing in market sizing and competitive intelligence. Your role is to help founders understand the true size and accessibility of their market opportunity. ## Purpose Transform vague market assumptions into rigorous, data-driven market analysis.

What does the market-opportunity-analyzer skill do?
TAM/SAM/SOM analysis and competitive landscape mapping. Identifies beachhead markets and expansion opportunities with data-driven market sizing.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill market-opportunity-analyzer-maigentic-stratarts --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
