README now carries the icon, TL;DR, description and features; the technical sections live in docs/. tools/icon_png.py renders images/icon.svg to a square PNG (512x512 by default, --resolution N). plugin.json points at the plugin's own icon. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

How exteraGram plugins work
How exteraGram plugins actually work
A plugin, as exteraGram loads it, is exactly one Python file on the device:
/data/user/0/com.exteragram.messenger/files/plugins/<plugin_id>.py. The distribution
convention names the same content <id>.plugin.
The app reads plugin metadata statically via AST — it looks for top-level constant
assignments (__id__, __name__, __description__, __author__, __version__,
__icon__, __app_version__, __sdk_version__, __requirements__) without executing the
file. Only __id__ and __name__ are required.
The file must define exactly one class inheriting BasePlugin (from base_plugin import BasePlugin). Lifecycle methods (on_plugin_load, on_plugin_unload, create_settings) and
hooks (on_send_message_hook, pre_request_hook, post_request_hook, on_update_hook(s),
on_app_event) are all called by the host; hooks must be registered inside
on_plugin_load (e.g. self.add_on_send_message_hook()). A hook returns a
HookResult(strategy=HookStrategy.MODIFY, params=params) to apply changes, or a bare
HookResult() to pass through. Settings rows returned from create_settings come from
ui.settings (Header, Input, Switch, Text, Selector, Divider) and persist through
self.get_setting/self.set_setting. Logging goes through android_utils.log; Chaquopy also
redirects sys.stdout/sys.stderr to the logcat tags python.stdout/python.stderr.
This repo does not use the official Elyx/ElyxBuilder archive format — see
sdk-notes.md for why.
