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_WORKFLOW_PROMPT_PROVENANCE

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

Workflow runs now label whether a person or a schedule triggered them, and quote the request.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.242.

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

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_workflow, up to twelve of them.

CLAUDE_CODE_WORKFLOW_PREFIX_STAGGER_MSParallel workflow agents stagger their first call to share cache; tune with an env var. 2.1.229 CLAUDE_CODE_WORKFLOW_SIZE_WARNING_AGENTSNo description from anybody. 2.1.203 CLAUDE_CODE_WORKFLOW_SIZE_WARNING_TOKENSNo description from anybody. 2.1.203 CLAUDE_CODE_WORKFLOWSEnvironment flags are now parsed centrally, so values are compared to explicit true or false. 2.1.146

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.
