yoclaw: Single-Binary AI Agent

yoclaw is a minimal, secure alternative to OpenClaw — a single Rust binary that turns any LLM into a persistent, tool-using agent on messaging platforms. Built on yoagent.

No Docker. No Redis. No infrastructure. One binary, one config file.

Core Capabilities

• Pluggable channels — Telegram today, Discord/Slack next. Add new platforms by implementing one trait.
• SQLite persistence — Conversations, message queue, long-term memory (FTS5), and audit logs in a single file.
• Crash recovery — Messages are queued before processing. Kill -9, restart, nothing lost.
• Security policies — Tool permissions, shell deny patterns, path/host allowlists, per-tool enable/disable.
• Budget tracking — Token and turn limits per day/session with automatic enforcement.
• Skills system — Drop markdown files into ~/.yoclaw/skills/ to teach your agent new capabilities.
• Worker delegation — Configure named sub-agents with different models for specialized tasks.
• Long-term memory — Full-text search over stored facts, preferences, and context.

Quick Start

# Build
cargo build --release

# Initialize config directory
./yoclaw init

# Edit config with your keys
vim ~/.yoclaw/config.toml

# Run
ANTHROPIC_API_KEY=sk-ant-... TELEGRAM_BOT_TOKEN=123:ABC... ./yoclaw

Configuration

[agent]
provider = "anthropic"
model = "claude-opus-4-6"
api_key = "${ANTHROPIC_API_KEY}"

[agent.budget]
max_tokens_per_day = 1_000_000
max_turns_per_session = 50

[agent.workers.research]
model = "claude-sonnet-4-20250514"
system_prompt = "You are a research assistant."
max_turns = 15

[channels.telegram]
bot_token = "${TELEGRAM_BOT_TOKEN}"
allowed_senders = [123456789]
debounce_ms = 2000

[security]
shell_deny_patterns = ["rm -rf", "sudo", "chmod 777"]

Customize the persona in ~/.yoclaw/persona.md.

Adding Skills

mkdir -p ~/.yoclaw/skills/my-skill
cat > ~/.yoclaw/skills/my-skill/SKILL.md << 'EOF'
---
name: my-skill
description: What this skill does
tools: [http]
---

Instructions for the agent when this skill is relevant.
EOF

Skills requiring disabled tools are automatically excluded.

Inspect

yoclaw inspect                    # Queue, sessions, budget, audit
yoclaw inspect --skills           # Loaded skills and their tool requirements
yoclaw inspect --workers          # Configured worker sub-agents
yoclaw inspect --session tg-123   # Filter audit by session

Architecture

Telegram → Coalescer → Queue (SQLite) → Conductor → Agent (yoagent) → Response → Telegram
                                            ↓
                                     Security Policy
                                     Budget Tracker
                                     Memory (FTS5)
                                     Worker Delegation

The Conductor owns a single yoagent Agent and switches between sessions by saving/loading conversation state. All tool calls pass through SecureToolWrapper for policy enforcement and audit logging.
