claude-persona

Claude Code skill inspired by TinyTroupe. It generates diverse AI persona panels, runs agent-separated concept interviews, and delivers structured research reports in one flow.

Each persona answers in its own claude -p subprocess with context isolation (--safe-mode) and server-validated structured output (--json-schema) — no inter-persona bias, no project-context leakage, no JSON parsing flakiness. Every run records its cost and the exact model IDs that served it. Works with all current Claude models (sonnet default; haiku, opus, and fable / Claude Fable 5 via "model" config or --model).

Who This Is For

• Marketers who need fast qualitative signal before paying for fieldwork
• Product managers testing concepts, messaging, packaging, or feature bundles
• Marketing data scientists, UX researchers, and strategy teams who want a reusable synthetic audience panel

Run a Study

Step 1 — Build a persona panel

/persona generate 10 Gen Z skincare shoppers in the US

10 diverse personas spanning different skincare attitudes:

Full panel (10 personas)

Other examples: Moms with babies shopping for strollers in the US, High income travelers choosing luxury hotels in Europe, 10 first-time meal kit subscribers in France, based on: 38% dual income couples, 27% families with young children

Step 2 — Explore motivations (optional but recommended)

/persona ask What frustrates you most about choosing skincare products?

Top themes surfaced:

• Ingredient and formula opacity — no concentrations, proprietary blends
• Greenwashing and legally meaningless claims ("clean", "clinically proven")
• Research burden pushed onto consumers — Reddit and INCIDecoder homework
• Information and choice overload, producing paralysis or disengagement
• Prestige pricing on identical actives

Step 3 — Run a concept test

/persona concept-test Compare 3 skincare concepts for Gen Z.

A: Acne Control Serum — fights breakouts with clinically proven actives
B: Barrier Repair Cream — strengthens skin barrier, reduces redness
C: Glow Boosting Toner — everyday radiance, brightens skin tone

Results:

• A: Acne Control Serum — 4/10 (40%) first choice
• B: Barrier Repair Cream — 4/10 (40%) first choice
• C: Glow Boosting Toner — 2/10 (20%) first choice
• Purchase likelihood: mean 3.2/5, range 1–5

A dead heat — each concept appeals to a distinct attitudinal cluster. Barrier repair won ingredient-conscious personas, acne control the problem-driven (and the skeptics, with low intent), and glow toner the smallest-but-most-enthusiastic camp.

Demos

The repository ships four complete demos with pre-generated personas and full results.

• Demo: Gen Z Skincare Concept Test — 10 personas, 3 skincare concepts
• Demo: Running Shoes Concept Test — 15 personas, 3 shoe concepts
• Demo: France Meal Kit Concept Test — 10 personas, France market, based on existing customer data
• Demo: Japan AI Meeting Notes SaaS — 10 personas, B2B SaaS, Japan market

All demo results were generated on claude-sonnet-4-6 (June 2026) with the exact serving model recorded in each run_metadata.json.

Why Trust the Results?

We re-ran every demo across three Claude model generations and tracked each persona individually: 84–100% of personas gave the same answer regardless of model, a repeated Claude Fable 5 run reproduced persona-level choices 100%, and no demo's winning concept ever changed. Responses are driven by the persona definitions, not model noise — and because each persona answers in an isolated subprocess that can't see your project files, your own context can't bias them either. Full data: model sensitivity study.
