Prompt Hub.
Every prompt versioned. Every Score pinned to the prompt that produced it.
Prompt Hub gives every prompt a commit history, environment labels you can switch without a redeploy, and a side-by-side diff between any two versions. Every Score and judgment Yardstick records pins to the exact prompt version that produced it, so 'this prompt got better' becomes provable instead of vibes. Works across any agent and any provider routed through Yardstick.
