Jsexec

Agent skill
1 skill

Use whenever you need to RUN Synchronet JavaScript — executing inline JS expressions, running scripts from the install's exec/ directory, testing JS modules, or validating changes to .js/.ssjs/.xjs files against a live install. This skill covers the jsexec runner itself: invocation modes, flags, output capture, crash tracing, and (on Windows) running a freshly-built debug binary. Trigger on "run a Synchronet script", "test this JS against Synchronet", "check what jsexec does", or any one-off JavaScript probe of a live install. For the JavaScript LANGUAGE and host API (how MsgBase/User/FileBase behave, SpiderMonkey dialect, the object model, writing tests, stock exec/.js) see the javascript skill.
