mesh-llm-plugin

mesh-llm-plugin owns the plugin author API and shared plugin wire protocol types used by host-side plugin runtimes and external plugins.

This crate includes:

• the plugin protobuf schema at proto/plugin.proto
• generated plugin protocol types exposed through mesh_llm_plugin::proto
• typed helpers for plugin manifests, operations, resources, prompts, tasks, mesh events, HTTP bindings, MCP projections, host-projected web UI bundles, and side-stream I/O

Plugins that declare web UI use the web_ui, web_ui_bundle, web_ui_page, and web_ui_config_section manifest builders. Declarative runtimes can place config schemas under config: [...] and UI declarations under web_ui: [...] in plugin!, alongside their real handlers. Macro fields remain in declaration order: metadata, optional startup_policy, provides, config, web_ui, mesh, events, mcp, http, inference, then lifecycle hooks. The v1 contract is local, same-origin, trusted, and projection-only; see docs/plugins/README.md and its maintained web UI exemplar.

Host-only orchestration, process lifecycle, plugin config loading, MCP bridge hosting, and built-in plugin wiring should remain in the host crate for now and move later to a dedicated plugin-host crate. Keep this crate focused on the stable API and protocol surface that plugin authors can depend on.
