[islandbitcoin]

🔄 Pulse v5.0 — Agent-Native Renovation Plan

Target Launch: May 22, 2026
Timeline: 13 weeks from Feb 19, 2026
Builders: AI agents (Corazon as product lead, coding agents for implementation)
Human review gates: Dread (architecture approval, prompt review, launch sign-off)

---

Executive Summary

Pulse v5 is a ground-up rebuild from a command-routing WhatsApp bot to an agent-native financial assistant. The LLM becomes the orchestrator — not a fallback. Every Flash wallet operation becomes an atomic tool the agent can compose. User context persists and compounds across sessions. New features ship as prompt files, not code deploys.

What we're shipping May 22:

• Personal Financial Agent (Ring 1) on WhatsApp Cloud API
• Agent loop with Claude tool-use as the brain
• Persistent user context (the moat)
• Core wallet operations (balance, send, receive, history, contacts)
• Account linking (OTP)
• Jamaican Patois dialect processing
• Voice support (ElevenLabs TTS + STT)
• Confirmation gates for all financial ops
• Structured observability logging

What we're NOT shipping May 22:

• Merchant agent (Ring 2) — post-launch
• Corridor/remittance agent (Ring 3) — post-launch
• Telegram, SMS, or other platform adapters — post-launch
• Full multi-dialect support (Trini/Bajan/Haitian) — post-launch
• Bill pay / mobile top-up — pending Flash API integration
• Virtual cards (Bridge.xyz/Rain.xyz) — future consideration
• v4 data migration — zero existing users, clean start

Architecture Decisions (Locked)

Decision	Choice	Rationale
WhatsApp delivery	Cloud API (not whatsapp-web.js)	Official, webhook-based, no Chrome dependency, scalable. Access exists via +13059244435.
Primary AI	Claude (Anthropic) with tool-use	Best-in-class tool use, reasoning, and safety for financial ops
Fallback/fast AI	Gemini Flash	Dialect detection, simple classification, cost optimization
Architecture	Agent-native (LLM-as-orchestrator)	Tools are primitives, prompts are features, agent composes behavior
Framework	NestJS + TypeScript	Consistent with v4 expertise, strong DI for hexagonal pattern
State	Redis (hot) + filesystem (persistent)	Fast context loading + durable storage
Context	Per-user persistent context	Compounds over time, creates defensible moat
Voice	ElevenLabs (TTS) + Whisper/Google (STT)	Preserve working v4 integrations
Observability	Pino structured logging + agent loop traces	Debug any user session, track tool execution
Process mgmt	PM2	Proven in v4, simple, effective
Validation	Zod	Runtime type safety for context, tool params, API responses
Testing	Jest	Unit + integration + dialect fixtures

Risk Register

Risk	Likelihood	Impact	Mitigation
WhatsApp Cloud API approval/rate limits	Medium	High	Start integration early (Week 3), have sandbox ready
Claude tool-use latency too high for chat UX	Medium	Medium	Model tier optimization, Gemini for fast tasks, response streaming
Flash API availability/staging access	Medium	High	Get staging credentials early, mock adapter for development
Dialect parsing accuracy	Medium	Medium	Start with Jamaican only, conservative matching, improve via logs
Context system prompt injection	Low	High	Sanitize all LLM-written context fields, test adversarial inputs
Scope creep (merchant, corridor, bill pay)	High	High	Locked scope. Post-launch backlog. Corazon says no.

2. UserContext schema — Does the context model capture what we need? (src/core/context/UserContext.ts)
3. Agent prompts — Does Pulse sound Caribbean, not corporate? (src/prompts/)
4. Confirmation gates — Is the payment confirmation matrix right? (src/prompts/system/safety-rails.md)

What's running now:

Integration agent is wiring the end-to-end flow (MessageOrchestrator → Context → Dialect → AgentLoop → Tools → Response).

Next after integration:

• Week 10: Testing + hardening
• Week 11: Staging deployment
• Week 12-13: Polish → Launch

We're ahead of schedule. 🚀

3. Flash API staging credentials — need staging/sandbox token
4. Internal testing — Dread + select testers on WhatsApp
5. Polish — prompt tuning from real conversations
6. Production launch — May 22

Blocking questions for Dread:

1. Where are we deploying? Existing VPS or new one?
2. Do we have Flash API staging credentials?
3. WhatsApp Cloud API — is the webhook URL configured to point to our server?
4. Who are the internal testers?

@dread — review the v5 branch when you wake up. Start with src/prompts/ (does Pulse sound right?) and src/ports/ (are the contracts right?).
