Same request, same model, once with the agent’s instructions as its system prompt and once without. Neither could use a tool. Read both and judge for yourself.

The tasks

written by Carte Blanche
example-1

“I'm planning to launch a subscription meal-kit service for busy parents in mid-sized US cities, priced around $9 per serving. Can you size the opportunity using a TAM/SAM/SOM breakdown, list the assumptions you use, and tell me which customer segments look most promising to target first?”

example-2

“We're a 12-person startup building scheduling software for independent physical therapy clinics, and we're considering expanding into the UK. Please assess the competitive landscape there: who the main incumbents are, how they price and position themselves, where the gaps seem to be, and what the key risks are for a small entrant like us.”

Install

Download the .zip and unzip it. Put market-researcher.md here:

Claude Code~/.claude/agents/Every project. For one project only, use .claude/agents/ inside it. It gives the agent the tools it asks for, and no others.
Cursor~/.cursor/agents/Cursor also reads the Claude Code folder above. It has no tools field, so it gives every agent every tool, whatever this one asks for.
CodexCodex’s custom agents are TOML files, not Markdown, so this agent doesn’t install there.

Keep its license file beside it, as market-researcher.LICENSE: a name that doesn’t end in .md, since every .md file there is read as an agent.

Then start a new session and ask for it by name. Folders checked 6 November 2026.

Or install from your agent: ask it to install market-researcher from Carte Blanche.
