What it does

Market Sizing Analysis is an agent skill from nicepkg/auto-company. This skill should be used when the user asks to "calculate TAM", "determine SAM", "estimate SOM", "size the market", "calculate market opportunity", "what's the total addressable market", or requests market sizing analysis for a startup or business opportunity.

Its SKILL.md is about 3.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `examples/saas-market-sizing.md` and `references/data-sources.md`).

It sits in Product & Project Management, covering Market sizing and Startup and business strategy. The repository describes itself as: 🤖 A fully autonomous AI company that runs 24/7. 14 AI agents (Bezos, Munger, DHH...) brainstorm ideas, write code, deploy products & make money — no human in the loop. Powered…

When your agent uses it

  • Asks to calculate TAM
  • Size the market
  • Calculate market opportunity
  • Whats the total addressable market

Example prompts

  • “calculate TAM”
  • “determine SAM”
  • “estimate SOM”
  • “/market-sizing-analysis”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Define the Market
  2. Gather Data Sources
  3. Calculate TAM
  4. Calculate SAM
  5. Calculate SOM
  6. Validate and Triangulate

What it can do on your machine

Read from SKILL.md and the folder at commit 1252920. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Market Sizing Analysis loads about 3.1k tokens when it runs, and up to ~5.4k if it reads all its reference files. Until then it costs about 71 tokens; SKILL.md has 1,335 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~3.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,335 words (~3,065 tokens).

“Comprehensive market sizing methodologies for calculating Total Addressable Market (TAM), Serviceable Available Market (SAM), and Serviceable Obtainable Market (SOM) for startup opportunities.”
