⚔️ Aetheel

A personal AI assistant that lives in Slack — with persistent memory, dual runtimes, and zero cloud dependencies.

Quick Start

One-line install

curl -fsSL http://10.0.0.59:3051/tanmay/Aetheel/raw/branch/main/install.sh | sh

This will clone the repo, set up a Python virtual environment, install dependencies, and walk you through configuration.

Manual install

git clone http://10.0.0.59:3051/tanmay/Aetheel.git
cd Aetheel
uv sync           # or: pip install -r requirements.txt
cp .env.example .env
# Edit .env with your Slack tokens

Run

# Default — OpenCode runtime
uv run python main.py

# Claude Code runtime
uv run python main.py --claude

# Test mode (echo handler, no AI)
uv run python main.py --test

# Custom model
uv run python main.py --model anthropic/claude-sonnet-4-20250514

# Debug logging
uv run python main.py --log DEBUG

Features

🧠 Persistent Memory System

• Identity files — SOUL.md (personality), USER.md (user profile), MEMORY.md (long-term notes)
• Hybrid search — 0.7 vector + 0.3 BM25 keyword scoring over all memory files
• Local embeddings — fastembed (ONNX, BAAI/bge-small-en-v1.5, 384-dim), zero API calls
• SQLite storage — FTS5 full-text search + JSON vector embeddings
• Session logs — Conversations auto-saved to daily/YYYY-MM-DD.md
• File watching — Memory re-indexes when you edit .md files

🤖 Dual AI Runtimes

Runtime	Flag	System Prompt	Session Continuity
OpenCode (default)	--cli / --sdk	XML-injected into message	--continue --session <id>
Claude Code	--claude	Native --system-prompt flag	--continue --session-id <id>

Both return the same AgentResponse — zero code changes needed to switch.

💬 Slack Integration

• Socket Mode — no public URL or webhook needed
• DMs + @mentions — responds in both
• Thread isolation — each thread gets its own AI session
• Chunked replies — auto-splits long responses at Slack's 4000-char limit

⏰ Action Tags

The AI can perform actions by including tags in its response:

[ACTION:remind|2|Time to drink water! 💧]

The system strips the tag from the visible response and schedules the action.

🔒 Local-First

• Embeddings run locally (no OpenAI/Gemini API for memory)
• Memory stored in ~/.aetheel/ — your data stays on your machine
• Only the AI runtime (OpenCode/Claude) makes external API calls

Configuration

Required: Slack Tokens

Variable	Where to get it
SLACK_BOT_TOKEN	api.slack.com/apps → OAuth & Permissions → Bot Token (xoxb-...)
SLACK_APP_TOKEN	api.slack.com/apps → Basic Info → App-Level Tokens (xapp-...)

See docs/slack-setup.md for full Slack app creation instructions.

AI Runtime

OpenCode (default)

Variable	Default	Description
OPENCODE_MODE	cli	cli (subprocess) or sdk (server API)
OPENCODE_MODEL	auto	Model, e.g. anthropic/claude-sonnet-4-20250514
OPENCODE_TIMEOUT	120	CLI timeout in seconds
OPENCODE_SERVER_URL	http://localhost:4096	SDK mode server URL
OPENCODE_WORKSPACE	.	Working directory for OpenCode

Claude Code (--claude)

Variable	Default	Description
CLAUDE_MODEL	auto	Model, e.g. claude-sonnet-4-20250514
CLAUDE_TIMEOUT	120	CLI timeout in seconds
CLAUDE_MAX_TURNS	3	Max agentic tool-use turns
CLAUDE_NO_TOOLS	true	Disable tools for pure chat

Memory System

Variable	Default	Description
AETHEEL_WORKSPACE	~/.aetheel/workspace	Path to memory files (SOUL.md, etc.)
AETHEEL_MEMORY_DB	~/.aetheel/memory.db	SQLite database path

General

Variable	Default	Description

---

Memory Files

Aetheel auto-creates three identity files in ~/.aetheel/workspace/:

File	Purpose
SOUL.md	Personality, values, communication style
USER.md	User preferences, context, background
MEMORY.md	Long-term notes, facts, things to remember

Edit these files directly — changes are picked up automatically via file watching.

Session logs are saved to ~/.aetheel/workspace/daily/YYYY-MM-DD.md and indexed for search.

---

Prerequisites

• Python 3.14+ (managed via uv)
• Slack workspace with bot + app tokens
• One of:
  • OpenCode CLI — curl -fsSL https://opencode.ai/install | bash
  • Claude Code — npm install -g @anthropic-ai/claude-code

---

Development

# Run tests
uv run python test_memory.py    # Memory system smoke test
uv run python test_slack.py     # Slack adapter unit tests

# Check help
uv run python main.py --help

Inspired By

Built with inspiration from OpenClaw — a TypeScript AI agent framework. Aetheel reimplements the core concepts (memory, hybrid search, session management) in Python with a local-first philosophy.
