The artifact list action takes a scope of mine, shared or all, plus new asset upload, delete and open modes.
The old artifacts tool verbs (upload_asset, read_file, read_asset, list_files, list_assets, list_types, describe_type, delete_asset) are replaced by a single action parameter on unified publish/list/read/delete tools. Calls made with the old verb names are rewritten via a regex table into the new phrasing (e.g. action: "upload_asset" becomes publish with asset: true, list_files becomes list with scope: "files"), and inputs/outputs are coerced between the legacy and new shapes so older prompts/skills keep working while the model is steered toward the new vocabulary.
The action: "list" action now accepts scope: "mine" (default), "shared", or "all", plus, when enabled, scope: "files", "assets", and "types". Publishing gains a new asset: true upload mode and a type_url describe mode, alongside a new delete action gated by t.deleteOn and an open action gated by t.openOn. A new validation branch also rejects a type argument unless the action is "list", clarifying that it names the type whose Artifacts to list, and that creating from a type should use type_url instead.
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.
The Configure page also shows the channel's resolved access. Its **Tools and access** tab lists the channel's resolved connections and any allowed domains. Members can see those lists but not change them there. The same tab's **Plugins** c…claude-tag/admins/customize see the edit
A connection grants access; a plugin teaches Claude how to use it well. A plugin is a packaged set of skills: reusable instructions for working with a specific tool or following a specific process. Attach a plugin to the same Access bundle…claude-tag/admins/add-connections see the edit
