Both are switched off here. Availability is read from `CLAUDE_CODE_ARTIFACT_TYPE_CATALOG`, falling back to the flag `tengu_cobalt_plinth_rowan`, whose built-in value is false, and neither exists in the previous build.\n\n**Details**\n\n- The value is computed once when the tool's schema is built and frozen for the session, and the wider artifact-types feature must also be on.\n- With it off, the actions do not appear in the tool's action list, the paragraph of the prompt that advertises them is omitted, and calls answer with an unavailable message or \"artifact types not available to this account\".\n- Permission text warns that titles and descriptions in these listings are written by their publishers and are read into the conversation.\n- Results render as \"listed N artifact types\" and \"described artifact type ... (N files ... ships instructions)\", and a not-found reply points you at using a `type_url` from `list_types`.\n\n**Evidence**\n\n`describing an Artifact type is not available in this session`, `artifact types not available to this account`, `if (i) c.push(\"list_types\", \"describe_type\");`, `list published artifact types (read-only; titles and descriptions written by their publishers)`\n\n- Flag `tengu_cobalt_plinth_rowan`: Off in both readings (read for one account on one subscription tier against v2.1.242; this account: off, anonymous baseline: off, compiled default: not a boolean we can read)\n- Area: Artifacts\n- Names: `CLAUDE_CODE_ARTIFACT_TYPE_CATALOG`\n- Tier: Nothing to try yet\n- Useful: 2\/5\n- Signal: 4\/5\n- Present in the build but not switched on"}
