[Aider v0.59.1] - it writes code that is not in my code base

[EliseiNicolae]

Issue

I have an app in flutter, and I'm using the following settings to start the aider:

aider:
	aider --yes --dark-mode --cache-prompts --map-tokens 2000 --model anthropic/claude-3-7-sonnet-latest --env-file .aider.env

The problem that I face is.. sometimes aider writes code that is not in my code base... e.g. it writes .cpp code.. and my app is in Flutter. It consume a lot of tokens when it did that.

Version and model info

Aider: Aider v0.59.1
Model:anthropic/claude-3-7-sonnet-latest

​I encountered a similar issue: the responses generated are significantly different from my requests. I've tried using models such as Llama 3.3, DeepSeek-R1:1.5B, and others.
Works well with openai models via api key. I think the problem occurred after Ollama update to 0.6.2 version.
Aider version: 0.78.0

I'm not sure I could tell you the source of the issue the information you've given. Maybe there's some C code in a dependency somewhere and that's getting picked up by the repomap? A solution may be to add a conventions file and have make sure it's always read into the context. See https://aider.chat/docs/usage/conventions.html

I think I fixed the issue by adding --subtree-only.

e.g:

aider:
	aider --yes --dark-mode --cache-prompts --map-tokens 2000 --model anthropic/claude-3-7-sonnet-latest --env-file .aider.env --subtree-only
