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

“We're redesigning the checkout flow for our meal-kit subscription app. Analytics show 38% of users drop off at the payment step on mobile, versus 19% on desktop. Can you write a moderated usability test plan for 6 mobile participants? Include recruiting criteria, 5 task scenarios, a few probing follow-up questions, and the success metrics we should track.”

example-2

“I just ran 8 interviews with freelance designers about how they track invoices and chase late payments. Key notes: 6 of 8 use spreadsheets, 5 said awkwardness about reminding clients is their biggest pain, 3 had missed tax deadlines, and 2 tried invoicing apps but quit because of fees. Can you synthesize these into 2 personas and a short list of prioritized insights we can use to shape our product roadmap?”

Install

Download the .zip and unzip it. Put ux-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 ux-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 ux-researcher from Carte Blanche.
