Unclear Whether a nested skill listed in an allowlist by its plain name is still covered is not clear.
What
Skills are reusable instructions Claude can run, and they can sit in nested folders, which gives them a scoped full name as well as a plain name. A skill now carries allowlistedByFullNameOnly when its full name differs from the plain name that appears in the allowlist.
A prompt-type command with allowlistedByFullNameOnly set is now left out by the same check that already left out prompts from memory stores and MCP servers.
Forked commands also work out which MCP read tools a hidden built-in can use.
Why
This affects whether allowed-tools rules apply to skills in nested folders, and may change which skills or commands are shown or listed.
