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

--environment-secret-file

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

Runner "pool" flags are renamed to "environment"; old names still work but warn.

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. v2.1.224"pool" renamed to "environment" in runner flags, old names still work

  2. v2.1.224Local runner spawn writes into ./runner-setup and checks 127.0.0.1:8080

    The setup wizard spawns a detached runner into ./runner-setup and warns it outlives your session.

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.

Names beside it

Every CLI flag in the inventory starting --environment, up to twelve of them.

--environmentCreate a new cloud session that runs on the [self-hosted environment](/docs/en/self-hosted-environments) with the given ID. Environment IDs start with ccpool_. See [--environment dispatch behavior](/docs/en/self-hosted-environments-testing#environment-dispatch-behavior) for dispatch behavior and the flag combinations it rejects. Requires Claude Code v2.1.224 or later never mined

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.
