When Claude Code withdraws these tools because they were denied, it now adds a marker saying so. This sits behind a remotely controlled switch that is off unless it is switched on remotely.\n\n**Why**\n\nThis may change how the model is told that a tool was denied.\n\n- Flag `tengu_composed_treehouse`: Not enough to say (read for one account on one subscription tier against v2.1.304; this account: no value returned, anonymous baseline: no value returned, 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- Area: Tools\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"}
