Those instructions can now end with an extra line when a certain condition about the available tools holds. Before, they had no such conditional line.\n\nClaude Code saves a copy of its prompt so it can be reused instead of sent again, called the prompt cache, and labels that copy with a key. The key now takes several more settings into account, so the saved copy is renewed when any of them changes.\n\nThe line telling Claude not to run `ls` or `find` stays behind a switch on Anthropic's servers that is off unless switched on remotely. The flag server returned off for this site's account and for an anonymous account, in a reading not yet taken under this release.\n\nIn the capture of the Bash tool's instructions taken under v2.1.323, the rule against committing files that likely contain secrets now also names `.claude\/settings.local.json`.\n\n**Why**\n\nThis changes the wording Claude sees for the Bash tool, which can affect how it chooses commands.\n\n- Flag `tengu_golden_thunder`: 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- Area: Bash Tool\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"}
