CLAUDE_CODE_CCR_SKIP_HYDRATE_ON_CURRENT_TIP

Updated November 6, 2026 by Alex Sorokoletov

CLAUDE_CODE_CCR_SKIP_HYDRATE_ON_CURRENT_TIP is a Claude Code environment variable: When set during connect, supplies the current tip position to hydration reads and the session link; otherwise those run without a tip position. Added in v2.1.319 and still present in v2.1.319. It is not in the official reference.

How to set it

For one session, export it in the shell that starts Claude Code:

export CLAUDE_CODE_CCR_SKIP_HYDRATE_ON_CURRENT_TIP=<value>
claude

To apply it to every session, add it to the env object of a settings file:

// ~/.claude/settings.json
{
  "env": {
    "CLAUDE_CODE_CCR_SKIP_HYDRATE_ON_CURRENT_TIP": "<value>"
  }
}

• CCR_FORCE_BUNDLE
• CLAUDE_CODE_DISABLE_EMPTY_CLASSIC_DISPATCH_SKIP: When set, prevents skipping a classic hook dispatch even when all its registered handlers satisfy the skip check, so the dispatch always runs.
• CLAUDE_CODE_SKIP_PROMPT_HISTORY: Disable prompt history saving.
• CLAUDE_RUNNER_SKIP_GIT_VERIFY: Set to 1 to skip checking that a checkout hook left a .git directory, for non-git source control systems; otherwise a missing .git fails the checkout.
