Create detailed, research-based UX personas for product and experience design. Use this skill whenever a user wants to create, improve, or critique personas โ€” including requests like "help me define our users", "create a persona for X", "build user profiles for our product", "we need to define our target audience", or "turn our research into personas". Also trigger when a user shares user research, interview notes, survey data, or user segments and wants to turn that into design-ready personas. Always use this skill before attempting to write any persona content from scratch.

UX Persona Creation

Personas are fictional but realistic descriptions of typical or target users. They synthesize research data into a single, memorable character โ€” making abstract user groups feel concrete and actionable for the whole product team.


When You're Asked to Create Personas

Follow this process:

1. Establish the research foundation

Ask the user what research they have available. Personas must be grounded in real data โ€” not assumptions. Accepted inputs:

  • Interview notes or transcripts
  • Survey results
  • Field study observations
  • Analytics segments
  • Existing user segments or market research

If no research exists, flag this clearly: a persona built without research is a assumption document, not a persona. Offer to help design a lightweight research plan, or proceed with clearly labeled "proto-personas" that should be validated.

2. Identify user clusters

From the research, group users by shared:

  • Behaviors and usage patterns
  • Goals and motivations
  • Frustrations and pain points
  • Context of use (when, where, how often, on what device)

If clusters are too similar, merge them. If a cluster seems peripheral to the product, consider dropping it. Aim for 2โ€“4 personas for most products โ€” enough to cover meaningful variation without diluting focus.

3. Build each persona

Each persona should include:

Required (core to memorability and empathy):

  • Name โ€” fictional but believable, not generic ("Anna", not "User A")
  • Photo โ€” describe one if you can't provide one (stock photo type, not a real person)
  • Age, location, occupation โ€” enough to anchor context
  • Tag line โ€” one punchy sentence capturing their essence. Keep it grounded, not clever.
  • Goals โ€” what are they ultimately trying to achieve? (2โ€“3 items)
  • Frustrations / pain points โ€” what currently gets in their way? (2โ€“3 items)
  • Behaviors โ€” how do they currently solve the problem? What tools, workarounds, habits?
  • Context of use โ€” how would they interact with your product? Required by job or by choice? How often? What device?
  • A quote โ€” one direct-voice sentence that captures their attitude toward the problem space

Optional (include only if design-relevant):

  • Experience level with similar products
  • Tech comfort level
  • Key tasks they need to accomplish in the product
  • Decision-making style

Never include details that don't affect design decisions. If a field doesn't make any design choice easier, cut it.

4. Apply the relevance test

Before finalizing any detail, ask: "Would this change a design decision?"

  • If yes โ†’ include it
  • If no โ†’ cut it

A persona's favorite coffee order is noise. Their preferred device and time of day for using the product is signal.


Output Format

Present each persona as a structured profile. Use this layout:

## [Name], [Age]
[Occupation] ยท [Location]

> "[Their defining quote]"

**[Tag line]**

### Goals
- ...
- ...

### Frustrations
- ...
- ...

### Behaviors
- ...
- ...

### Context of use
[1โ€“2 sentences on how, when, and where they'd use the product]

Common Mistakes to Avoid

| Mistake | Fix | |---|---| | Building personas from assumptions, not research | Ground every trait in observed data | | Too many personas | 2โ€“4 is almost always enough | | Including irrelevant details | Apply the relevance test to every field | | Making the tag line too witty | It should be useful, not entertaining | | Treating personas as a one-time deliverable | Revisit them as you learn more | | Designing only for the primary persona | Secondary personas represent real edge cases |


Using Personas Beyond the Design Phase

Once created, personas have several ongoing uses:

  • Expert reviews โ€” walk through a task flow as each persona to surface issues
  • Usability study recruiting โ€” use persona traits as screening criteria
  • Stakeholder alignment โ€” give teams a shared vocabulary ("Would Rosa actually do this?")
  • Analytics segmentation โ€” map real user segments to persona profiles to validate and refine
  • Agency/consultant briefs โ€” describe your audience concisely without exposing raw data

Persona Quality Checklist

Before delivering personas to the user, verify:

  • [ ] Each persona is grounded in real research (or clearly labeled as proto-persona)
  • [ ] Name and photo aid memorability
  • [ ] Goals and frustrations reflect user research, not product team assumptions
  • [ ] Every included detail passes the relevance test
  • [ ] Tag line is clear and useful, not just clever
  • [ ] Personas feel like distinct characters, not slight variations of each other
  • [ ] 2โ€“4 personas total (flag if more are requested and explain the tradeoff)

ux research methods

Guide selecting the right UX research method for a given situation. Use this skill whenever the user asks which research method to use, how to plan UX research, what research to do at a given product stage, how to study user behavior vs. attitudes, how to pick between qualitative and quantitative approaches, or whether to run interviews, usability tests, surveys, A/B tests, or any other UX research technique. Also trigger when the user describes a research question and wants a recommendation, or when they ask about the tradeoffs between specific methods. Trigger even if the user just says "what research should I do" or "how do I learn more about my users" without naming specific methods.

ux storyboard

Create UX storyboards from scratch, from user research, or from existing journey maps. Use this skill whenever a user wants to create a storyboard, visualize a user scenario, illustrate how a user interacts with a product, or communicate a UX story to a team or stakeholders. Also trigger when the user asks to "sketch a user flow", "show how a user would use X", "create a scenario illustration", "map out a use case visually", or wants to present research findings in a visual, narrative format. Even if the user doesn't say "storyboard" explicitly โ€” if they want to show a sequence of steps a user takes, trigger this skill.

ai governors

Apply the Governors framework to design or audit human-in-the-loop features that keep users informed, in control, and safe as AI acts autonomously. Use this skill whenever someone is designing or reviewing AI product features involving oversight, trust, transparency, or control โ€” including "how do I keep users in the loop", "how should I handle risky AI actions", "users don't trust the AI", "how do I prevent costly AI mistakes", "should I ask for confirmation before this action", "how do I show AI reasoning", "users are scared the AI will overwrite their data", "how do I handle AI memory and privacy", or any request about making an AI feature feel safe and controllable. Trigger even when the user doesn't say "governor" or "human-in-the-loop" โ€” if they're designing any AI feature and the question touches on control, trust, transparency, cost, risk, or oversight, use this skill.
