What probably matters to youSection of the release
Unclear Where the extra files and note come from is not stated.
What
/run is a skill, a packaged set of instructions Claude Code can follow, for launching your project's app to see a change working. It, and one other skill, now combine their bundled files with extra files from another source. When a third argument is present, a note from that source is added to the prompt too.
Before, the files came only from the bundled skill.
Why
This may let the skill use run instructions specific to your project.
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
