Developer Builds Custom Business System on Claude with Persistent Memory and Skill Compositions
System Architecture and Components
A developer has built a comprehensive business system using Claude Pro that functions as a "second brain" with persistent memory and automated workflows. The system includes 13 custom skills that trigger by name, each with defined inputs, outputs, and project applicability.
Key Features
- Custom Skills: Skills include build mode (reads project architecture, checks changelog, saves version snapshots), reflect skill (7-domain product audit), and problem solving skill (tactical mode for negotiations with scripts and leverage maps)
- Persistent Memory: Maintains resonance files with deep records of thinking patterns, frameworks, decision-making processes, and feedback. Claude starts sessions with knowledge of business architecture, communication style, client pipeline status, and validated patterns
- Daily Intelligence Briefing: Scheduled task runs at 5AM called "Mind's Eye" that queries operation pipeline movements, invoice statuses, task drift, finance pressure, and stalled prospects. Compares to yesterday's state, finds cross-domain connections, and sends Gmail digest
- Skill Compositions: Chains (sequential pipelines like research prospect, draft outreach, schedule follow-up) and fusions (multiple skills running in parallel whose outputs converge into something none could produce alone)
- "Infinity Barrier": System runs at full speed but deposits all outputs into staging layer. Nothing touches clients, prospects, or real world until explicit approval
Technical Stack
- Supabase for database, auth, and edge functions
- Cloudflare Pages for hosting, DNS, and email routing
- Claude Pro subscription
- Gmail MCP, Google Calendar MCP, Cloudflare MCP, Chrome automation
- Vanilla HTML/CSS/JS with browser-native ES modules (no frameworks)
Business Functions
- Automated prospect research generates new leads daily
- Personalized outreach drafts with research-backed angles
- Client invoicing flows through Stripe with automated commission calculations
- Client sites deploy through scripted pipelines
- Morning briefing catches patterns like "client's invoice overdue AND project tasks incomplete"
The system's philosophy is to automate mechanical tasks, amplify strategic thinking, and maintain human judgment for approvals.
