Claude Code v2.1.301 ·

Reported entrypoint now comes from a helper before CLAUDE_CODE_ENTRYPOINT

The entrypoint label in the billing header and the User-Agent now asks a helper first, then CLAUDE_CODE_ENTRYPOINT, then a fallback

Unclear What the new first source returns, and so whether CLAUDE_CODE_ENTRYPOINT can still decide the label, is not clear.

What

Claude Code tells Anthropic's servers how it was started, called the entrypoint (for example, from the command line). Two places that send this label now ask a new helper first.

  • The cc_entrypoint value in the billing header uses the helper's answer, then CLAUDE_CODE_ENTRYPOINT, then unknown.
  • The entrypoint part of the claude-cli/ User-Agent (the identifying string sent with each request) uses the helper's answer, then CLAUDE_CODE_ENTRYPOINT, then cli.

Before this release, both read CLAUDE_CODE_ENTRYPOINT directly.

Why

If you set CLAUDE_CODE_ENTRYPOINT, it may no longer be the value reported, because the helper's answer now comes first. The label Anthropic receives for how Claude Code was started may change.
