Skill + CLI Interaction
When a CLI enters a botmux session, it automatically gets ~/.botmux/bin in its PATH, along with a set of ready-to-use Skills. This is the channel through which a CLI agent can proactively interact with a Lark topic.
Out-of-the-Box Capabilities
These capabilities are injected via --append-system-prompt plus Skill descriptions that automatically guide the agent to use them.
Why Skill + CLI Instead of MCP
Compared with Anthropic's official MCP-based approach, the Skill + CLI combination:
- The CLI doesn't need an MCP handshake on startup, and doesn't consume tool-list tokens
- It is universal across Claude Code / Codex / Cursor / Gemini / OpenCode / Antigravity — all it needs is a CLI that can read a system prompt and run shell commands; it doesn't depend on any MCP protocol support
Wrapper Mechanism
In-session commands rely on the wrapper script at ~/.botmux/bin/botmux, which the daemon writes automatically at startup and adds to the worker's PATH, so its version always matches the daemon (no separate npm i -g needed). Session info is inferred automatically from ancestor-process markers, so the agent doesn't need to pass a session id manually.
