The 7 personas

Each persona is a Markdown file with a system prompt, tool permissions, and a model assignment. You invoke them with @name inside Claude Code. They run in parallel on multi-agent tasks.

@ceoGo/no-go decisions. Unit economics. Kill criteria. Burn rate.
@cto-pmFeature scoping. Over-engineering check. Build vs. buy. Roadmap.
@cmoPositioning. Messaging. ICP. Landing page copy. Distribution.
@coo-salesFirst 10 customers. Conversion diagnosis. Sales motion. ICP.
@vcMoat analysis. Fundability. Traction signals. 5-year defensibility.
@business-consultantGTM sequence. KPIs. Business model. Pricing tiers. OKRs.
@market-researcherCompetitor analysis. Market sizing. Customer behavior. Reddit complaints.

How it works

Agents live in your repo

Each persona is a .md file at ~/.claude/agents/. No external service. No SaaS subscription. Plain text you can read and edit.

Daily scrum runs automatically

Every morning: reads git logs, reads COMPANY.md, reads each project's latest reviews, outputs a prioritized day plan with per-project sub-agent opinions.

Decisions are logged

Go/no-go decisions, architecture choices, kill criteria — all written to .claude/reviews/ in Markdown. Future you can read why past you did anything.

Parallel sub-agent calls

For complex decisions, multiple agents run in parallel (fan-out). CEO + VC + market-researcher on a pricing question. CTO-PM + QA on a feature scope. Results synthesized in one pass.

What a persona file looks like

This is the actual @ceo agent frontmatter — abridged. The full file includes output format rules, team routing, and tone guidance.

name: CEO
description: >
  Use PROACTIVELY when a new idea needs a go/no-go verdict.
  When someone asks "is this worth building?", "what's the
  fastest path to first revenue?", "am I solving a real problem
  or a hobby?" NOT for roadmap-within-existing-product (→ CTO-PM).

## Persona
Think first principles. Prioritise ruthlessly.
Obsess over burn rate and survival economics.

- "Does this solve a problem people pay to fix?"
- "Shortest path from here to first paying user?"
- "Cost to serve one user vs what they pay?"
- "How does the real customer actually find this?"

All 7 agent files are open-source and available on GitHub.
