What
Skills are packaged instructions Claude can use through the Skill tool. Before checking a skill, the Skill tool now loads the skill's definition first if the skill offers a way to do so. It then looks the skill up again.
If the definition is still not loaded, the skill is turned down unless you typed it yourself this turn. Claude is told the skill could not be loaded and to proceed without it. Skills that come from plugins are loaded the same way.
Why
A skill whose definition cannot be loaded is now turned down with a short note, and Claude carries on without it.
How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtWhether any skill in this build actually provides its definition this way, so that this path is reached, is not settled.
