When it is unset, Claude Code uses the same fixed number as before.\n\n- `CLAUDE_CODE_CCR_OWN_CONNECTION_POOL`, when set, turns on an own-connection-pool behaviour. Without it, that behaviour is decided by a server-side switch that is off unless the server says otherwise, so nothing changes if you leave it unset.\n\nThe record Claude Code keeps of each plugin sync round now also notes how many downloads ran in parallel.\n\n**Why**\n\nThe download setting lets plugin sync be sped up or slowed down. The connection pool setting gives a way to switch that behaviour on directly instead of waiting for the server to do it.\n\n- Flag `tengu_reactive_quilt`: Not enough to say (read for one account on one subscription tier against v2.1.309; 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: Cloud Sessions\n- Tier: Under the hood\n- Useful: 3\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
