SkyClaw v2.2 Rust AI Agent Runtime Adds OpenAI OAuth and Custom Tool Authoring

SkyClaw v2.2 Release Details

SkyClaw v2.2 is an open-source AI agent runtime written in Rust that communicates through Telegram, Discord, and Slack channels. The agent can execute shell commands, browse the web, manage files, self-heal, and learn from mistakes.

New Features in v2.2

• OpenAI OAuth - Use ChatGPT Plus/Pro subscriptions instead of API keys. Authentication: skyclaw auth login, select model, done. According to the source, only two agent runtimes support this: OpenClaw and SkyClaw.
• Custom Tool Authoring - The agent writes its own bash/python/node tools at runtime. Example: Ask it to "make a tool that checks my server status" and it creates a script, saves it, and reuses it across sessions without restarting.
• Daemon Mode - skyclaw start -d / skyclaw stop for background operation without tmux.

Performance Benchmarks

• 31ms cold start
• 15 MB idle RAM
• 17 MB peak during conversation
• 9.3 MB single binary
• For comparison: OpenClaw needs ~1.2 GB idle RAM and ~800 MB install size

Technical Specifications

• 56K lines of Rust code
• 1,278 tests
• Zero warnings, zero panic paths
• 7 AI providers supported
• 4 communication channels (Telegram/Discord/Slack/others)
• 13 built-in tools + MCP self-extension
• 14 server registry - agent installs new tools autonomously

This type of lightweight, self-extending agent runtime is useful for developers who want AI assistants that can operate efficiently on constrained systems while maintaining extensibility through custom tool creation.
