DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Reference / CLI flags

--sdk-url

A Claude Code CLI flag, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

What it is

Startup stats now note the input format, whether --sdk-url was passed, and an experiment flag.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.232.

Presence across releases

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Changelog entries naming it

  1. v2.1.233Gateway can forward user identity headers, plus a new ccr-gateway host mode

    Gateway upstreams can pass your sanitised identity headers along, and a new ccr-gateway host mode takes its origin from --sdk-url.

    named in this entry

  2. v2.1.232More detail in startup analytics

    Startup stats now note the input format, whether --sdk-url was passed, and an experiment flag.

Documentation pages

None of Anthropic's documentation pages this site has a copy of carries this name.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the CLI flag does. All CLI flags.
