Skills System With Invocation Patterns And Core Skill Library

via “skills system with custom agent capability extensions”

A lightweight alternative to OpenClaw that runs in containers for security. Connects to WhatsApp, Telegram, Slack, Discord, Gmail and other messaging apps,, has memory, scheduled jobs, and runs directly on Anthropic's Agents SDK

Unique: Implements a standardized skills interface (documented in .claude/skills/debug/SKILL.md) that allows developers to create custom agent capabilities with declared inputs/outputs, enabling skill composition and reuse across agents without hardcoding integrations

More structured than ad-hoc agent code because skills have a standardized interface; more flexible than hardcoded capabilities because skills can be added without modifying core agent logic
