The agent has two orthogonal customization axes:
  1. Persona preset — what the agent prioritises (functional focus)
  2. Personality profile — how the agent talks (voice / tone)
You can mix any preset with any personality.

​
Persona presets (personaPreset)

Set via:
You can also append a free-form override that’s injected after the preset:

​
Personality profiles (personalityProfile)

The personality shapes the voice of the briefing — same data, very different feel. Set via:

​
Same data, different voices

Given the same low-conversion situation, here’s how three personalities respond:
balanced “Conversion is at 0%. We had 3,828 impressions and not a single page view. Worth a metadata pass this week.”
blunt_advisor “0% conversion. 3,828 impressions wasted. Your screenshots are not connecting. Fix this today.”
yc_partner “What’s the conversion rate? 0%? On 3,828 impressions? That’s the only number that matters this week. Why hasn’t this moved? What’s the single most important metadata change you could ship today?”

​
Custom prompt override

personaPrompt is appended after the preset and personality. Use it for:
  • Context only you know: “My app is for diabetic athletes — never recommend generic fitness keywords.”
  • House style: “Write in lowercase. No emoji.”
  • Tradeoffs: “Profitability matters more than growth right now.”
It’s just text — there’s no schema. Keep it tight (200-400 chars works best).

​
Choosing combinations

Some combinations that work especially well:
  • growth + yc_partner — pre-PMF teams that need to learn to look at the funnel honestly
  • pm + friendly_mentor — solo devs who need encouragement to keep shipping
  • aso_specialist + blunt_advisor — apps where ASO is the obvious bottleneck and you need a kick
  • cfo + pg_analytical — understanding why unit economics are the way they are
  • default + indie_hacker — the “ship fast and iterate” weekend warrior loop
