+
+If aider prompts you to add a new file to the chat and you say yes,
+it will re-submit the original request. 
+The fact that the LLM's reply indicated that it needed to see another file (and you said yes)
+is often a sign that the LLM should have been able to see/edit that file in the first place. 
+Without access to it, there is increased chance that it's done a bad implementation of the requested change.
+Often LLMs will hallucinate content for the files they needed but didn't have.
+So aider re-submits the original request in this situation.

-Aider works best with LLMs which are good at *editing* code, not just good at writing
-code.
-To evaluate an LLM's editing skill, aider uses benchmarks that
-assess a model's ability to consistently follow the system prompt
-to successfully edit code.
+Aider excels with LLMs skilled at writing and *editing* code,
+and uses benchmarks to
+evaluate an LLM's ability to follow instructions and edit code successfully without
+human intervention.
+[Aider's polyglot benchmark](https://aider.chat/2024/12/21/polyglot.html#the-polyglot-benchmark) tests LLMs on 225 challenging Exercism coding exercises across C++, Go, Java, JavaScript, Python, and Rust.
 
-The leaderboards report the results from a number of popular LLMs.
-While [aider can connect to almost any LLM](/docs/llms.html),
-it works best with models that score well on the benchmarks.

-[Aider's polyglot benchmark](https://aider.chat/2024/12/21/polyglot.html#the-polyglot-benchmark) 
-asks the LLM to edit source files to complete 225 coding exercises
-from Exercism. 
-It contains exercises in many popular programming languages:
-C++, Go, Java, JavaScript, Python and Rust.
-The 225 exercises were purposely selected to be the *hardest*
-that Exercism offered in those languages, to provide
-a strong coding challenge to LLMs.
-
-This benchmark measures the LLM's coding ability in popular languages, 
-and whether it can
-write new code that integrates into existing code.
-The model also has to successfully apply all its changes to the source file without human intervention.
