[EXTENSIBILITY] Plugin system for third-party extensions

[jwesleye]

Feature Description

Plugin architecture for custom tools, formatters, exporters, etc.

Problem/Motivation

Core should stay lean. Community wants to extend without modifying core.

# Install plugin
pip install chat-loop-plugin-notion

# Use plugin
chat_loop myagent --plugin notion-exporter

# Plugin API:
# - Hooks into lifecycle
# - Custom commands
# - Output formatters
# - Tool providers

Benefits

• Ecosystem growth

Priority

Closing as not planned.

A plugin system would add significant complexity and maintenance burden that doesn't align with the AWS Strands CLI focus. This tool is designed to be a simple, focused chat interface for AWS Strands agents.

If extensibility is needed in the future, we can revisit this, but for now it's out of scope for the core mission of providing an excellent chat loop experience.
