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 stopfor 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.
