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 / Environment variables

CLAUDE_CODE_COORDINATOR_WORKER_CHECKIN_SECONDS

A Claude Code environment variable, 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

Set an interval and your coordinator session gets periodic worker status nudges listing each worker's activity.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.246.

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. v2.1.248Three new environment variables

    Three new env vars tune the read-only memory notice, async agent stall timeout and check-in interval.

    named in this entry

  2. v2.1.246Periodic status nudge for long-running dispatched workers

    Set an interval and your coordinator session gets periodic worker status nudges listing each worker's activity.

    named in this entry

  3. v2.1.246A second kind of periodic check-in alongside goal check-ins

    Coordinator worker check-ins are their own check-in type with their own interval setting and reset behaviour.

    named in this entry

Documentation pages

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

Names beside it

Every environment variable in the inventory starting claude_code_coordinator, up to twelve of them.

CLAUDE_CODE_COORDINATOR_EXTRA_TOOLSNo description from anybody. 2.1.178 CLAUDE_CODE_COORDINATOR_FORCE_WORKER_INHERIT_MODELAn env var forces coordinator workers onto the session's model, ignoring any requested one. never mined CLAUDE_CODE_COORDINATOR_MODEYou can mark one MCP server in .mcp.json as the coordinator's user-facing server. 2.1.152

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 environment variable does. All environment variables.
