CwdChanged

hook never mined documented JSON

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

When the working directory changes, for example when Claude executes a cd command. Useful for reactive environment management with tools like direnv

Anthropic's own wording. Read off Hooks reference, captured 2026-10-22.

The earliest release whose published evidence quoted CwdChanged was v2.1.229, 12 Aug 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table below.

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.

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 hook event does. All hook events.
