# Fixes and re-tests

Canonical: https://devtune.ai/product/retests

## Ship the fix. Re-test what it touched.

Scenarios coding agents lose you become fixes in Actions, and a re-test of each shipped fix records the pick rate before and after.

#### Fixes from losses

When another tool, or one the agent builds itself, clearly beats you in a scenario, the loss becomes a ranked fix in Actions. Each fix carries the runs behind it.

#### Re-test what the fix touched

Once a fix is live, re-test only the scenarios it lost in, with the same test app, request, agent and model as the original test.

#### Pay only for the runs you need

See the credit estimate and confirm it before a re-test runs. It stops once every scenario has clearly moved, and the credits for runs it skips come back.

#### Before and after pick rates

See each re-tested scenario's pick rate before and after, with the likely range. The result goes to Results and shows what moved, not what caused it.
