Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install market-sizing-tam-sam-som

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent defines the market boundaries, then computes TAM both top-down and bottom-up, narrows to SAM and estimates SOM over 1 to 3 years. You get a summary table, growth drivers and a numbered list of assumptions with confidence levels.

Updated November 2, 2026

Three nested circles showing TAM, SAM and SOM with their estimates.

Frequently asked questions

Are the numbers reliable?

They depend on the sources found through web search. The skill asks for citations and a confidence level per assumption, so verify the most uncertain ones.

Is web search required?

It is recommended for current data. Without it, you can supply your own reports or figures and the agent will analyze them.
