# Skill versions

Every skill is versioned. A version pins the skill's file manifest, so the
instructions and supporting files can be reconstructed later. Version history
appears in the **Source** tab, not in a separate profile tab.

## Read the history

The version picker in **Source** shows:

* the live version
* release dates and contributors
* earlier published or superseded versions

Version history makes usage evidence easier to interpret. A trace attributed to
version `2.2.0` can be compared with the exact source that was live for that
run, even after `2.3.0` replaces it.

## Roll back safely

Choose an earlier version, then select **Restore** when the current release is
not behaving as expected. Restore creates a new live version from the selected
files; it does not erase the releases that came after it. The full history
remains available for review.
