Hermes Lark Streaming by Aowen-Nowor for Hermes Agent

Feishu/Lark CardKit v2.0 plugin for Hermes Agent with streaming cards and a typing effect

What Hermes Lark Streaming does

The plugin is a refactor of an earlier Cheerwhy/hermes-lark-streaming project, with extensive changes that make it incompatible with that upstream version, so the README asks anyone with the original installed to remove it first. It installs through the Hermes plugin manager from either Gitee or GitHub, reads the HERMES_HOME environment variable automatically, and is enabled and activated with hermes gateway restart. Settings live under a hermes_lark_streaming section in config.yaml, auto-injected on first load.

A doctor command gives a one-stop diagnostic covering plugin version, Python environment, configuration, Feishu credentials, patch status and log paths, and a cleanup command removes the injected configuration before uninstalling. The README explicitly warns that a hermes-lark-streaming package published on PyPI under the name aidu POP is an unrelated third-party upload, not published by this project, and says not to install it with pip.
