# Aider chat conversation:
USER: Modify proxychain.go such that there is a public API to add a ResponseModification to fire only once.
ASSISTANT: To make this change we need to modify `proxychain/proxychain.go` to:
1. Add a new field `onceResultModifications` in the `ProxyChain` struct to store the response modifications that should only fire once.
2. Add a new method `AddOnceResponseModification` to add a response modification that should only fire once.
3. Update the `_execute` method to apply the `onceResultModifications` and clear them after they have been applied.
Here are the *SEARCH/REPLACE* blocks:
