market-analyzer

market-analyzer is a skill for Claude Code, Codex from varunk130/ai-gtm-skill-library. It costs 66 tokens per session (1,057 once invoked), scanned A, original, MIT.

A market research and sizing tool for defining a market and mapping its size, growth, risks, segments, and competitors. It goes beyond TAM, SAM, and SOM, which are estimates of a market’s total, serviceable, and obtainable size.

In plain words
What is it for?
Use it to assess entering a market, validate product strategy, prepare investor or board briefings, create fundraising slides, or support annual planning. Provide the market category, geographic scope, and time horizon.
Why use it?
It helps replace a basic market-size estimate with a clearer view of how the market is structured and what may affect it. The analysis also makes the assumptions and boundaries of the market explicit.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

market-analyzer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Market Analyzer (SCOPE Framework)

Full-spectrum market analysis producing investment-grade market maps with sizing, growth drivers, risk factors, and segment-level deep dives. Goes beyond basic TAM/SAM/SOM.

When to Use

  • New market entry decisions
  • Board/investor market briefings
  • Product strategy validation
  • Fundraising market slides
  • Annual strategic planning

What You'll Need

Critical inputs (ask if not provided):

  • Market or product category to analyze
  • Geographic scope (global, US, EMEA, etc.)
  • Time horizon (current year + forecast period)

Nice-to-have:

  • Whitespace Finder output (opportunities to size)
  • Signal Radar output (trends affecting the market)
  • Existing market data or analyst reports

Process

Step 1: Market Definition

Before sizing, rigorously define the market boundaries:

  • Category definition: What products/services are included? What is excluded?
  • Buyer definition: Who purchases? (roles, company types, segments)
  • Use case definition: What problems does this market solve?
  • Adjacent markets: What related markets overlap or compete for budget?

Step 2: SCOPE Analysis

Analyze the market across 5 structural dimensions:

Dimension What It Covers Key Questions
Size & Growth TAM/SAM/SOM + growth trajectory How big? How fast growing? Top-down AND bottom-up?
Competitive Density Number and strength of competitors How crowded? Any dominant players? Fragmented or consolidated?
Opportunity Windows Timing-sensitive opportunities What market shifts create openings? What is the window duration?
Power Dynamics Who holds power in the value chain Buyer power? Supplier power? Platform dependencies? Regulatory influence?
Economic Drivers What drives market growth or contraction Macro trends? Technology adoption curves? Budget cycle patterns?

Step 3: Multi-Method Sizing

Use THREE methods and triangulate:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
