How an agent calls it
Agents call this ability by name and pass the inputs it needs. A call looks roughly like this:
{
"ability": "acf-extended.set-custom-field-group-key",
"args": { "input": ... }
}The agent runs the ability, then hands the result back for you to review before anything is published.
