persona

MANDATORY PREPARATION

Invoke /product-thinking — it contains product principles and the Context Gathering Protocol. Follow the protocol before proceeding — if no product context exists yet, you MUST run /teach-acumen first.

---

Mindset: A persona is a behavior pattern, not a demographic profile. "Batch-processes weekly reports and breaks when export stalls" is a persona. "Sarah, 32, marketing manager" is not.

Behavior

When called with a specific persona or user segment: Build or update that persona. Ask the user what behaviors they've observed, what triggered this, and what signals they're reading.

When called without argument: Review all personas for staleness and gaps. Flag personas that feel assumed rather than observed. Identify missing behavior patterns.

Research Process

1. Read .acumen.md for product context — users, job to be done, feedback source, metrics
2. Read .acumen/personas.md for existing personas
3. If a feedback source is configured in .acumen.md, ask the user to share recent feedback or pull from the configured source to ground personas in real signals
4. For each persona (new or updated), build from behavior outward:
   • What job are they hiring the product to do?
   • What's the context when they use it? (time pressure, environment, emotional state)
   • What's their actual behavior pattern? (frequency, workflow, workarounds)
   • What's the pain that drives them to the product?
   • What does success look like for them? (not for you — for them)
   • What triggers them to start a session?
   • What's their value sensitivity? (price, time, reliability, flexibility)
   • What feedback signal would tell you this persona is happy or churning?

Output

- **Trigger**: [What starts a session — event, schedule, frustration]
- **Value sensitivity**: [What they'd pay for, what they'd leave over]
- **Feedback signal**: [How you'd detect satisfaction or churn for this persona]

## [Next persona...]

## Prioritization
[Which personas matter most right now and why. Not all personas are equal — be explicit about who you're building for first and who you're consciously underserving.]
