Claude plugins bring their own runtime requirements. claude-mem and others run
their hooks under bun, which the sandbox image does not carry, so installing
plugins left every prompt in the sandbox failing with a Bun not found hook
error - after setup had reported success, since the dependency only surfaces
when a hook fires.
AI_SBX_TOOLS lists mise tools to install globally in the sandbox and defaults
to bun. mise is already present and resolves these from GitHub releases, which
the default network policy allows. Setting the variable to an empty string
installs nothing.
