Ask any agent with the plugin. You don't name the skill.
You should see
The agent picks the release-note skill on its own and writes a short note: what shipped, and what you do next. Nothing else loads.
Then say "set up Tune-Up" to meet the bot.

Questions people ask #
Which agents does it work with? #
Grok Bot today. Ask Tune-Up to get a note when yours is supported. We don't promise dates.
Will it change my agents without asking? #
No. It shows every change first and applies one only after your yes. It never changes an agent's purpose or deletes one.
Does it send my data anywhere? #
The plugin has no tracking. It reaches the network only to search skill marketplaces when no local skill fits, and saves nothing until you say add.
Does it download whole marketplaces? #
No. Marketplaces are only searched. Only a skill you choose to add is saved to your library.
Can I write my own skills? #
Yes. A skill is a folder with a SKILL.md. Start from the three starter skills in the repo.
What does it cost? #
Nothing. It's free and open source under the MIT license.
Ask Tune-Up. #
