Installing, enabling, disabling, removing, or reloading a plugin updates every live session's skill list and system prompt together before the operation returns; a session that takes too long to converge is cut off after a timeout and updated on the next plugin change instead.

In a running session, system-prompt contributions take effect on `/plugins reload` — the same point where the plugin skill list refreshes: the reload re-renders every live session's prompt with the current sections.

In a running session, system-prompt contributions take effect on `/plugins reload` — the same point where the plugin skill list refreshes: the reload re-renders every live session's prompt with the current sections. Installing, enabling, disabling, or removing a plugin without reloading leaves live prompts unchanged, and a session resumed from disk keeps its persisted prompt. Toggling a plugin's MCP server does not touch prompts. +New sessions and newly created agents read the contributions from the plugins currently enabled. An in-flight request keeps its existing system prompt. `/plugins reload` refreshes the plugin skill list and requests prompt rebuilds for live agents; use it when you need the change to converge deliberately before the next turn. On the v2 engine, installing, enabling, disabling, or removing a plugin updates the catalog immediately and a later prompt rebuild — for example after compaction or a tool-policy change — may pick up the new sections. The legacy engine keeps each live session's plugin snapshot until `/plugins reload` or a new session. A resumed session starts from its persisted prompt, and later rebuilds follow the engine-specific behavior above. Toggling a plugin's MCP server does not change system-prompt sections. The built-in agent prompt includes instructions from enabled plugins automatically. A custom `SYSTEM.md` or agent file owns its template, so include `${plugin_sections}` where plugin-contributed instructions should appear. If the custom template includes `${base_prompt}` and that effective default already contains the plugin block, do not add `${plugin_sections}` again.
