Claude Code Plugin for Agentsd
|
||||
==============================
|
||||
|
||||
Bridges locally installed Claude Code CLI into agentsd as a standard plugin.
|
||||
Enables agentsd to use Claude Code for code generation, editing, and reasoning.
|
||||
|
||||
Architecture:
|
||||
agentsd (Rust) ←gRPC→ claudecode_plugin.py → claude CLI (subprocess)
|
||||
|
||||
Capabilities:
|
||||
- chat: Send a prompt to Claude Code, get response
|
||||
- code: Generate/edit code with full Claude Code capabilities
|
||||
- session: Resume previous Claude Code sessions
|
||||
- tools: Let Claude Code use its built-in tools (Bash, Edit, Read, etc.)
|
||||
|
||||
Usage:
|
||||
# Start agentsd first, then:
|
||||
python claudecode_plugin.py
