What

The generated sandbox profile now grants access to mcp-skill-archives, mcp-discovery-cache and shares under the config home, so MCP skill archives and the MCP discovery cache work inside the sandbox.

Details
  • Added alongside existing entries such as loop.md and scheduled_tasks.json.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
