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

--project

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

Cloud session creation can use a newer request shape for review and plan sources.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.224.

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. v2.1.248Project and agent dispatch still need an endpoint your account may not have

    Cloud sessions with --project or a specific agent are refused if your account lacks the newer endpoint.

    named in this entry

  2. v2.1.232--project no longer starts a cloud session

    Passing --project alone won't start a cloud session; --ref and --on-branch now need --cloud or --environment.

    named in this entry

  3. v2.1.227Device-bound sessions reject --project and agent ownership up front

    Device-bound sessions now reject a project id or agent id immediately with a clear message.

    named in this entry

  4. v2.1.224Cloud sessions can be created through a newer request shape

    Cloud session creation can use a newer request shape for review and plan sources.

    named in this entry

  5. v2.1.224Newer cloud session creation endpoint for review and plan sources

    Cloud sessions from review or plan sources can use a newer creation endpoint allowing --project grouping.

Documentation pages

A reference table page is one whose own table defines this name, and it is where the description above came from. A page that mentions it carries the name somewhere in its text and may say nothing about it at all. Every page carrying it.

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.
