Dreamfinder

"One little spark of inspiration is at the heart of all creation."

An AI-powered project management bot for Signal, built for the Imagineering organization. Named after the Dreamfinder from EPCOT's Journey Into Imagination — the imaginative mentor who dreamed Figment into existence — Dreamfinder turns sparks of ideas into organized tasks, docs, and team coordination.

The bot processes every message through a Claude LLM agent loop with access to ~75 tools across task management (Kan.bn), knowledge base (Outline), calendar (Radicale), web automation (Playwright), and custom bot tools. No slash commands — just natural language.

Status: End-to-end bot is deployed and running. 519+ tests, 14 domain tables, schema v5. Features: Signal client, agent loop, DB-backed conversation history, tool registry, MCP manager (~75 tools), system prompt with context injection, RAG long-term memory (Voyage AI embeddings), standup orchestration, deploy announcements, OAuth auth (Claude Max), calendar event awareness, autonomous dream cycle with parallel branching, and kickstart guided onboarding (in progress). Adapted from xdeca-pm-bot, a production Telegram bot with the same architecture.

Features

Task Management (via Kan.bn)

  • Create, update, and close tasks through natural conversation
  • List tasks by board, list, assignee, or label
  • Manage checklists, comments, and labels
  • Sprint planning and tracking

Knowledge Base (via Outline)

  • Search and retrieve documents
  • Create and update wiki pages from chat
  • Browse collections and recent documents

Calendar (via Radicale)

  • View upcoming events and deadlines — 7-day lookahead injected into system prompt
  • Create and manage calendar events
  • Todo list management
  • Timezone-aware display (EVENT_TIMEZONE)

Team Coordination

  • Async daily standups — bot prompts team members and collects responses
  • Standup summaries posted to group
  • Timezone-aware prompt scheduling (per-group IANA timezone config)
  • User identity mapping (Signal UUID to Kan.bn user)

Bot Intelligence

  • Full natural language understanding — no slash commands needed
  • Conversation history with 20-message window and 30-minute TTL
  • RAG long-term memory — Voyage AI embeddings, cosine similarity retrieval, context injection
  • Rate limiting in group chats to avoid noise
  • Configurable per-chat settings (enabled tools, response style)
  • Bot personality/identity customization

Dream Cycle

Autonomous multi-phase agent session triggered by "goodnight" messages, modeled after real sleep stages:

Light (N1→N2) → Deep (N2→N3) → Branch per spark (parallel) → REM (converge) → Wake
  • Light Sleep: Files obvious items from chat history into Kan/Outline
  • Deep Sleep: Finds connections, surfaces [SPARK] tags for creative threads
  • Dream Branching: Each spark becomes a parallel agent thread (Future.wait)
  • REM Convergence: Merges branch reports, finds meta-patterns
  • Waking Message: In-character summary with dream stats
  • Adaptive depth — quiet days skip deeper phases
  • Token usage tracked across all phases and branches

Kickstart Guided Onboarding (In Progress)

5-step guided setup triggered by natural language ("kickstart", "get started", etc.):

  1. Workspace Setup — Link Kan workspace and default board
  2. Team Roster — Map Signal users to Kan members
  3. Project Seeding — Create cards and docs for active projects
  4. Knowledge Dump — Capture decisions, conventions, context
  5. Dream Primer — Summarize setup and introduce the dream cycle

Reminders (Cron-based)

  • Standup prompts at configured times (timezone-aware)
  • Overdue task alerts (planned)
  • Stale task nudges (planned)

  • Anthropic API key
  • Running instances of Kan.bn, Outline, and Radicale

Installation

# Clone the repo
git clone git@github.com:imagineering-cc/dreamfinder.git
cd dreamfinder

# Install dependencies
dart pub get

# Set up environment
cp .env.example .env
# Edit .env with your credentials

# Run the bot
dart run bin/dreamfinder.dart

Environment Configuration

All environment variables are documented in .env.example:

# Required
ANTHROPIC_API_KEY=            # Claude API key
SIGNAL_PHONE_NUMBER=          # Bot's registered Signal phone number
SIGNAL_API_URL=               # signal-cli-rest-api base URL

KAN_BASE_URL=                 # Kan.bn instance URL
KAN_API_KEY=                  # Kan.bn API key
OUTLINE_BASE_URL=             # Outline instance URL
OUTLINE_API_KEY=              # Outline API key

# Radicale (optional — calendar/contacts features)
RADICALE_BASE_URL=            # Radicale CalDAV/CardDAV server URL
RADICALE_USERNAME=            # Radicale auth username
RADICALE_PASSWORD=            # Radicale auth password

# Bot Config (all optional, have defaults)
BOT_NAME=                     # Display name (default: "Dreamfinder")
DATABASE_PATH=                # SQLite path (default: ./data/bot.db)
LOG_LEVEL=                    # Logging level (default: info)

Signal Bot Setup

Signal does not have an official bot API. Dreamfinder uses signal-cli-rest-api — the most mature community solution. It wraps signal-cli in a Docker container exposing REST endpoints that SignalClient (in Dart) consumes via HTTP polling.

# docker-compose.yml (simplified)
services:
  signal-api:
    image: bbernhard/signal-cli-rest-api:latest
    ports:
      - "8080:8080"
    volumes:
      - ./signal-cli-config:/home/.local/share/signal-cli
    environment:
      - MODE=normal

  bot:
    build: .
    depends_on:
      - signal-api
    environment:
      - SIGNAL_API_URL=http://signal-api:8080

Pros: Battle-tested, large community, well-documented REST API, runs as a separate concern.

Cons: Extra container to manage, polling-based message receipt (or webhook setup), indirect communication.

MCP Integration

MCP (Model Context Protocol) servers run as child processes managed by McpManager. The dart_mcp package provides the Dart client for MCP protocol communication — STDIO transport wiring is in progress.

Available Tool Sets (~75 tools total)

Server Tools Examples
Kan.bn ~15 List boards, create card, update card, manage labels
Outline ~15 Search docs, create document, list collections
Radicale ~15 List events, create todo, manage contacts
Playwright ~20 Navigate, screenshot, fill form, click element
Custom ~10 Chat config, user mapping, sprint info, standups

Custom Tools

In addition to MCP server tools, the bot defines its own tools in lib/src/tools/:

  • chat_config — Workspace linking, default board/list config per group
  • user_mapping — Map Signal UUIDs to Kan.bn users and display names
  • bot_identity — Get/set bot name, pronouns, and communication tone
  • memory — Save, search, and manage long-term RAG memories
  • standup — Collect and summarize daily standup responses
  • kickstart — Advance and complete guided onboarding steps

Testing

We follow ATDD (Acceptance Test-Driven Development):

  1. Write an acceptance test describing the desired behavior
  2. Watch it fail
  3. Implement the feature
  4. Watch the test pass
  5. Refactor

Tests are organized to mirror the lib/src/ directory structure inside test/. Integration tests for MCP tools use recorded fixtures to avoid hitting live services. We use mocktail for mocking.

Deployment

Docker

# Build and start all services
docker compose up -d

# View logs
docker compose logs -f bot

# Restart bot only
docker compose restart bot

The Docker Compose setup includes:

  • bot — The Dart application
  • signal-api — signal-cli-rest-api container

GCP

Deployment target is Google Cloud Platform. Specific infrastructure (Cloud Run, GCE, GKE) is TBD based on Signal bridge requirements. The signal-cli-rest-api container needs persistent storage for Signal account state, which influences the deployment model.

Relationship to xdeca-pm-bot

This project is a direct adaptation of xdeca-pm-bot (private repo), a production Telegram bot serving the xDeca organization. The core architecture is identical:

Aspect xdeca-pm-bot Dreamfinder
Language TypeScript Dart
Messaging Telegram (grammY) Signal (signal-cli-rest-api)
Organization xDeca Imagineering
LLM Claude Sonnet 4.6 Claude Sonnet 4.6
MCP Tools Kan, Outline, Radicale Kan, Outline, Radicale
Database SQLite + Drizzle SQLite (sqlite3 package)
Agent Architecture Same Same
Deployment Docker on GCP Docker on GCP

Key Differences from Telegram

Signal presents unique challenges compared to Telegram's mature Bot API:

  • No official bot API — Relies on unofficial signal-cli tooling
  • Phone number required — No bot tokens; needs a real phone number
  • No inline keyboards — Cannot send interactive button menus
  • No message editing — Cannot update previously sent messages
  • Stricter rate limiting — Signal is more conservative about message frequency
  • Disappearing messages — Must handle ephemeral message settings gracefully
  • UUID-based identity — Users identified by UUID, not numeric ID

These constraints shape the UX: responses must be complete (no editing), interactions are purely text-based (no buttons), and the bot must be mindful of message frequency.
