Plugins vs scripts

Both use the hc name, but they serve different purposes:

	Request scripts	Plugins
Lifetime	One-shot per send	Long-lived until deactivated
Runtime	utilityProcess + SES	Renderer: registry + IPC; main: same runner
API scope	Request, variables, tests, response	UI contributions, themes, storage, fs, HTTP hooks, IPC
Where defined	Collection or request editor	Installed .hcp package

Request scripts cannot call plugin-only APIs. Plugins do not replace collection or request scripts for per-send logic. For the script hc reference (hc.request, hc.variables, hc.test, and related members), see Request scripts.
