The Rival Brief

What you get

You don't know who you are really up against.

The Rival Brief finds out.

You give it your website address. It sends out six research helpers to look at your competitors:

• What they charge
• What their customers say
• How they sell

About 10 minutes later you get:

• A positioning brief
• Seven battle cards (one page per rival)
• A pricing map
• A report that checks its own work

That replaces a day of reading competitor tabs.

Free. No keys. About 5 minutes to set up.

One thing to know

Prices come from web search. They can be out of date. Re-check any price on the rival's own pricing page before you use it.

Always put your own website address in the prompt. If you don't, it can build on a wrong guess about you.

Some sites, like Reddit, may be unreachable. It will tell you when that happens.

Who this is for

You are a founder or marketer. You want to know who you are really up against.

What you need

• Claude Code
• git (a tool that downloads projects)
• Your own website address
• About 10 minutes for each run

When Claude asks, allow web search and web fetch.

Set it up

Step 1: Get the skill

It downloads the project. A skill is just text files, so there is no code to install.

git clone https://github.com/ferdinandobons/startup-skill.git

Step 2: Copy the folder in

It puts the competitor skill where Claude Code looks for skills. Do this inside the project you want researched.

mkdir -p .claude/skills && cp -r startup-skill/startup-competitors .claude/skills/

Use it

Open Claude Code in that project. Say:

Use startup-competitors. My site is https://yourwebsite.com. Who are my main competitors?

It asks a few questions first. Then it works.

You get a folder of files like this:

positioning-brief.md
competitors-report.md
pricing-landscape.md
7 battle cards
verification-report.md

If something goes wrong

Nothing happens. Check the folder is at .claude/skills/startup-competitors. Then restart Claude Code.

It stalls on a permission. Allow web search and fetch.

A price looks wrong. Open the rival's pricing page and check it.
