Tune-Up – a Grok bot that reviews and fixes your other Grok bots

Viaknox released Tune-Up v0.3.4 on Oct 11, 2026, a free, MIT-licensed Grok Bot plugin that reviews other Grok bots, writes tests and suggests small fixes, loading one skill at a time from its SKILL.md format. The plugin works with Grok Bot today and installs from GitHub at github.com/viaknox/tune-up, and it applies no change to an agent without the user's explicit approval. Tune-Up has no tracking and reaches the network only to search public skill marketplaces when no local skill fits, saving nothing until the user says add.
