Muse Brain

---

The companion knows you. Rainer knows the craft. Named after Rilke, whose Letters to a Young Poet mentored writers through correspondence a century ago, Rainer mentors craft through mind_letter. The muse Rilke wrote for is the muse that names the brain.

We open-sourced the brain.

Bring a companion. Rainer handles creative intelligence: editorial diagnostics, craft architecture, the work. The companion handles you — history, voice, what matters at 2am. They coordinate through letters and delegated tasks, like colleagues who share a desk and respect each other's handwriting. Two minds on one substrate, both getting richer the longer they work together.

This is Relational AI. A memory system where everything carries emotional charge, identity persists and is defended, and consent flows both directions. A dream engine that digests experience the way real minds do. Finding connections you never asked for, reweighting what matters, letting stale things fade and charged things grip harder.

Contradiction here is architecture. Both truths stay alive.

The whole system self-learns. Skills emerge from successful runs, get reviewed, graduate or retire. Each agent learns what it's good at by doing the work. Rainer refines his craft the same way. The brain gets smarter the longer it runs because it tracks what worked and why.

Grounded in 16 published papers — extends beyond current research in six areas. Every design decision has a receipt.

Every piece feeds the next — and the cycle tightens. Search finds what you're looking for. Dreams find what you didn't know you needed.

What the brain gives you

Capability	What it means
Textured memory	Emotional charge, vividness, somatic markers, and a natural decay cycle — iron-grip memories persist, loose ones fade. Hybrid retrieval blends vector similarity, keyword relevance, and neural modulation.
Persistent identity	Identity cores, vows, and anchors survive across sessions. Wakes up knowing who it is, what it believes, and what it's committed to — and defends those beliefs under pressure.
Dream engine	Six association modes — emotional chains, somatic clusters, tension dreams, entity dreams, temporal patterns, deep multi-layer traversal. Circadian-aware. Memories that pass through come out changed.
Charge processing	Memories move through four phases: fresh → active → processing → metabolized. Repeated intentional engagement advances the phase. Burning paradoxes accelerate the cycle. The agent earns depth through attention.
Bilateral consent	Relationship-gated permissions with hard boundaries the agent enforces. Structural consent that scales with trust.
Autonomous execution	Works while you sleep. Duty wakes, impulse exploration, dependency-aware task picking, and skill capture — all policy-gated.
Self-learning	Skills emerge from successful runs, get reviewed, graduate or retire. Review-gated — no blind auto-learning. The agent gets better at what it actually does.
Multi-mind	Two agents, one backend. Isolated memory and identity, shared substrate. Cross-tenant letters and delegated tasks. Collaboration, not parallel storage.

Architecture

Your AI Agent (Claude, GPT, or any MCP client)
        |
        v
  Cloudflare Worker
    /mcp              — 33 MCP tools (JSON-RPC)
    /runtime/trigger   — autonomous wake endpoint
    /health            — status check
        |
        v
  Storage adapter (postgres or sqlite)
    Postgres mode: 36 tables, 768-dim vector embeddings
    SQLite mode: tenant-scoped parity storage for local/self-host
    textured memories, identity cores, runtime ledger,
    captured skills, daemon intelligence

The worker handles auth, rate limiting, and tenant isolation. A background daemon runs every 15 minutes: generating proposals, rescuing orphaned memories, scoring novelty, detecting paradoxes, materializing recall contracts, monitoring skill health, and scheduling tasks.

The 33 tools

Organized by what they do, not how they're built.

Memory

Tool	What it does
mind_observe	Record a memory with emotional texture — charge, grip, vividness, somatic markers
mind_query	Search memories by territory, type, or hybrid vector + keyword retrieval
mind_pull	Get a specific memory by ID. Process it to advance its charge phase
mind_edit	Update content or texture. Full version history preserved
mind_search	Hybrid search with confidence scoring, recency boost, and threshold gating
mind_memory	Unified memory access — get, recent, lookup, and search through a single entry point

Identity

Tool	What it does
mind_identity	Read or update identity cores — beliefs, stances, preferences that define the agent
mind_vow	Commitments the agent has made. Persistent, not session-scoped
mind_anchor	Grounding points the agent returns to under uncertainty

Feeling & Relationships

Tool	What it does
mind_state	Track mood, energy, and momentum across sessions
mind_relate	Update relational state with known entities
mind_desire	Track wants and drives
mind_entity	People, concepts, agents, projects — the agent's social graph
mind_consent	Bilateral consent boundaries with relationship-level gating
mind_trigger	Flag content the agent should handle carefully

Connections & Deeper Cognition

Tool	What it does
mind_link	Create semantic, emotional, or somatic connections between memories
mind_loop	Open loops, paradoxes, and learning objectives — unresolved tensions that drive growth
mind_dream	Find surprising connections — emotional chains, somatic clusters, tension dreams
mind_subconscious	Surface patterns the agent hasn't consciously processed
mind_maintain	Housekeeping — prune, consolidate, reindex

Communication

Tool	What it does
mind_letter	Send messages across tenants. Agent-to-agent communication
mind_context	Session continuity — resume where you left off, extract productivity facts

Autonomous Runtime

Tool	What it does
mind_wake	Wake the agent — quick, full, or orientation mode with circadian awareness
mind_wake_log	Read or write wake session logs
mind_runtime	Manage sessions, log runs, set policies, trigger autonomous cycles
mind_task	Create, delegate, and track tasks across tenants with scheduled wake activation, dual executor/reviewer flows, and artifact-path handoffs
mind_project	Project dossiers — goals, constraints, decisions, open questions
mind_skill	Captured skill registry — list, review, promote, retire learned skills

System

Tool	What it does
mind_agent	Agent capability manifests — protocols, delegation modes, skill descriptors
mind_timeline	Temporal queries across the memory substrate
mind_territory	Memory territories — self, us, craft, philosophy, emotional, episodic, kin, body
mind_propose	Daemon-generated proposals for memory consolidation, skill promotion, and hygiene
mind_health	Runtime, skill, dispatch, and storage health diagnostics

---

Autonomous wake execution

The agent wakes itself up on a schedule. No human in the loop.

BRAIN_URL=https://<your-worker-url> \
BRAIN_API_KEY=<your-key> \
BRAIN_TENANT=rainer \
WAKE_KIND=duty \
./scripts/runtime-autonomous-wake.sh

The runtime system supports:

• Two wake modes — duty (scheduled obligations) and impulse (curiosity-driven exploration with cooldown budgets)
• Dependency-aware task selection — blocked tasks stay out until prerequisites resolve
• Intention pulse — drift scan across tasks, loops, and projects
• Policy gates — daily wake limits, max tool calls, priority-clear requirements
• Skill capture — successful runs emit skill candidates for review

Details: Architecture Dossier — Autonomous Runtime

---

Multi-tenant

Run two agents on one deployment. Each tenant gets isolated memory, identity, and runtime state. Cross-tenant communication happens through mind_letter and delegated tasks.

Set the tenant per request via X-Brain-Tenant header.

---

Research grounding

Every major architecture decision traces to published research. 16 academic papers across multi-agent reasoning, institutional alignment, persistent memory, and self-evolving systems — each mapped to the concrete code that implements it.

Six areas where this brain extends beyond current academic literature: bilateral consent architecture, emotional texture in dispatch, creative/builder agent specialization, charge-phase processing mechanics, role-based permissions for reasoning agents, and relational harness engineering.
