How that note reaches Claude has changed:\n\n- It now sits behind a different server-controlled switch, which is also off unless it is turned on remotely\n\n- It is skipped for skills owned by Anthropic and synced to you\n\n- It is added as one line starting \"compatibility:\", instead of two separate pieces of text, one of which was fixed guidance\n\n**Why**\n\nThis changes what Claude reads about a skill's requirements when the switch is on.\n\n- Flag `tengu_expressive_island`: Off in both readings (read for one account on one subscription tier against v2.1.323; this account: off, anonymous baseline: off, compiled default: off) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Flag `tengu_fancy_canyon`: Off in both readings (read for one account on one subscription tier against v2.1.323; this account: off, anonymous baseline: off, compiled default: not a boolean we can read) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: Skills\n- Tier: Nothing to try yet\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no\n- Present in the build but not switched on"}
