Homebrew for Personal AI Infrastructure

The 10-star vision for GBrain's integration system. Ship Approach B (v0.7.0), build toward this over subsequent releases.

The Vision

GBrain becomes a personal infrastructure operating system where every signal in your life flows through the brain automatically. Integrations are senses (data inputs) and reflexes (automated responses to patterns). Users subscribe to the creator's actual operating system, then customize it.

$ gbrain integrations

  SENSES (data inputs)                          STATUS
  -------------------------------------------------------
  voice-to-brain    Phone calls -> brain pages  ACTIVE    last call: 2h ago
  email-to-brain    Gmail -> entity updates     ACTIVE    47 emails today
  x-to-brain        Twitter -> media pages      ACTIVE    312 tweets tracked
  calendar-to-brain Google Cal -> meeting prep  ACTIVE    3 meetings tomorrow
  photos-to-brain   Camera roll -> visual mem   AVAILABLE
  slack-to-brain    Slack -> conversation index  AVAILABLE
  rss-to-brain      RSS feeds -> media pages     AVAILABLE

  REFLEXES (automated responses)                STATUS
  -------------------------------------------------------
  meeting-prep      Brief me before meetings    ACTIVE    next: 9am tomorrow
  entity-enrich     Auto-enrich new contacts    ACTIVE    12 enriched today
  dream-cycle       Overnight brain maintenance ACTIVE    last run: 3am
  deal-tracker      Alert on deal changes       AVAILABLE
  follow-up-nudge   Remind on stale threads     AVAILABLE

  This week: 1,247 signals ingested. Top: email (47%), voice (23%), X (18%).
  34 new entity pages created. 7 calls transcribed.

  Run 'gbrain integrations show <id>' for setup details.

The user feels: "My brain is alive. It's watching everything I care about, and it's getting smarter every day. I didn't have to write any code. I just said yes when the agent asked."

Architecture: Senses & Reflexes

[Opinionated setup instructions the agent executes...]

Dependency Graph

Recipes declare requires in frontmatter. The CLI resolves dependencies before setup. If voice-to-brain requires credential-gateway, the agent sets up credential-gateway first.

credential-gateway
  ├── voice-to-brain (requires credentials for Twilio)
  ├── email-to-brain (requires credentials for Gmail)
  └── calendar-to-brain (requires credentials for Google Calendar)

x-to-brain (standalone, uses X API directly)

Health Dashboard

gbrain integrations doctor runs health_checks from every configured recipe:

$ gbrain integrations doctor
  voice-to-brain:   ✓ Twilio reachable  ✓ OpenAI key valid  ✓ ngrok tunnel up
  email-to-brain:   ✓ Gmail auth valid   ✗ No emails in 48h (check cron)
  OVERALL: 1 warning

Sense Analytics

gbrain integrations stats aggregates heartbeat data:

$ gbrain integrations stats
  This week: 1,247 signals ingested
  Top sources: email (47%), voice (23%), X (18%), calendar (12%)
  34 new entity pages created
  7 calls transcribed
  Brain growth: 12,400 → 12,834 pages (+434)

Reflex Rules Engine (future)

Reflexes are recipes that trigger on brain state changes:

---
id: deal-tracker
category: reflex
triggers:
  - type: page_updated
    filter: {type: deal, field: status}
  - type: timeline_entry
    filter: {source: email, mentions: deal}
action: alert
---

When a deal page's status changes or a new email mentions a deal,
alert the user with context from the brain.

Roadmap

Version	What Ships	Key Recipe
v0.7.0	Recipe format, CLI, SKILLPACK breakout	voice-to-brain
v0.8.0	3 more senses, reflex format	email, X, calendar
v0.9.0	Community recipes, install executor	community submissions
v1.0.0	Full senses/reflexes, health dashboard	meeting-prep, dream-cycle

Key Design Decisions

GBrain is deterministic infrastructure. Cross-sense correlation, pattern detection, and intelligent responses are the agent's job (OpenClaw/Hermes). GBrain provides the plumbing.
Agents ARE the runtime. No npm packages, Docker images, or deterministic scripts. The recipe markdown IS the installer. The agent reads it and does the work.
Very opinionated defaults. Ship the creator's exact production setup as the default. Users customize from there. Unknown callers get screened. Quiet hours are enforced. Brain-first lookup happens on every call.
Agent-readable outputs. All CLI output must be parseable by agents (--json flag). Migration files include agent instructions. The agent is the primary consumer, not the human.
