Under the hood

The bundled browser-automation skill added a new internal script file for allowing tools

What

The built-in "run" skill, which handles browser automation, added a new file called allow-tool.mjs to its internal library folder, alongside the existing files that handle configuration, discovery, guarding, hosts, and tools.

Why

This is an internal addition to how the skill manages which tools are allowed to run; the finding doesn't specify what behavior it changes for users.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtThe finding shows only that the file was added, not what logic it contains or how it changes the skill's behavior.
