Requirements

• Node.js 20+
• An Anthropic API key: export ANTHROPIC_API_KEY=sk-ant-...

| Department | What it produces | |-------------|-----------------------------------------------| | strategy | Idea canvas, market research, lean canvas | | brand | Brand brief, voice/tone, pitch deck | | product | Roadmap, personas, MVP definition, sprint 1 | | finance | Financial model, pricing, unit economics | | marketing | GTM strategy, email sequences, launch plan | | sales | Playbook, objection handling, CRM setup | | legal | Entity guidance, IP checklist, compliance | | people | Culture doc, job descriptions, interview kits | | operations | Tech stack, SOPs, meeting system | | metrics | KPI framework, north star, investor updates | | security | Threat model, vuln scan, dependency audit | | engineering | Code review, type safety, CI validation |

All output is written to your current directory as Markdown files.
