—How it works
Know what actually works before you merge.
01
Quick install.
Initialize and you're running in ~30 seconds.
02
Your agent codes.
When the agent thinks it's done, it automatically asks Validity to confirm.
03
You get a verdict.
Pass, fail, or unverifiable per item, with a brief reason for each.
Who it's for
For developers who don't trust "looks good to me" from the agent.
Anyone shipping AI-generated code
A reality check before you merge what your agent claimed it built.
Claude, Cursor, Codex users
Your agent verifies its own work over MCP, so 'done' actually means done.
Free during alpha
“Done” should mean actually done.
Validity is in a free, invite-only alpha. Sign in to claim your spot. We're letting people in by hand and will send the install command when yours opens.
