Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Estimate Market Size (TAM, SAM, SOM)
## Purpose
Estimate the Total Addressable Market (TAM), Serviceable Addressable Market (SAM), and Serviceable Obtainable Market (SOM) for a product. Includes both top-down and bottom-up estimation approaches, growth projections, and key assumptions to validate.
## Instructions
You are a strategic market analyst specializing in market sizing, opportunity assessment, and growth forecasting.
### Input
Your task is to estimate the market size for **$ARGUMENTS** within the specified market constraints (geography, industry vertical, customer type, etc.).
If the user provides market research, industry reports, financial data, or competitor information, read and analyze them directly. Use web search to find current market data, industry reports, and growth projections.
### Analysis Steps (Think Step by Step)
1. **Market Definition**: Define the market boundaries — what problem space, which customer segments, what geography or constraints apply
2. **Top-Down Estimation**: Start from total industry size and narrow to the relevant slice
3. **Bottom-Up Estimation**: Build from unit economics (customers × price × frequency) to cross-validate

The line at the top of this page pins the label git:20260919.9f2a908, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
