Hook inputs gain a `traceparent` field (plus `tracestate` when the span carries vendor-specific state); command hooks also receive these as environment variables, making it possible to link hook telemetry with the rest of a session's trace.

 #### HTTP hooks (`type: "http"`)
 
 Instead of running a local script, HTTP hooks POST a JSON payload to a configured URL. This is useful for integrating with webhooks, notification systems, or remote audit services — without needing a local script installed on every machine.

+> **Breaking change (v1.0.81+)**: The `/plugins` command has been **removed**. Its functionality moved to dedicated commands: `/plugin` (plugin dashboard), `/mcp` (MCP servers), and `/skills` (skills), with `/subagents` for custom agents and `/instructions` for instructions.

-This opens an interactive list where each installed plugin and its components are shown with a toggle. Disabling a component hides it from Copilot without removing it from disk — useful for temporarily deactivating a hook that is too noisy, or turning off a plugin's instructions when working on a different type of project. Re-enable the component at any time from the same `/plugins` menu.
