I'm trying to understand if terminal output, especially the spam generated during automated tests and other system messages, counts towards the context window when using Claude Code to run bash commands. This excessive output often fills up the context window quickly, making it hard for Claude Code to have enough context to complete tasks effectively. What are some strategies I can use to minimize this output and manage what goes into the context window when it's executing commands and reading files?

One effective method I found was to write a bash script that filters out the unnecessary output, focusing only on failed tests and a few lines after the failure. Additionally, you can direct stdout to /dev/null for code formatting, which helps limit the output. To make this seamless, I plan to set up aliases so that the script runs automatically whenever I execute the usual test commands. That should help manage the clutter a bit better!
I'm also wondering about this! It seems like a big issue when there’s too much clutter in the terminal output.
It can also help to run tests in a Task and only retrieve the most pertinent results, though that might slow things down. Ideally, you'd want to tweak the logging levels of your tests. Start by lowering the logging to eliminate unnecessary output, and only increase it when you’re focused on specific tests. You could create a makefile or a script to easily adjust these settings on the fly, making it simpler to manage differing log levels or options for testing.
I face a similar challenge working in a large team, so I can’t just refactor all the automated tests. However, I've been using a bash script to filter the output, which seems to help!
That's a smart approach! Using aliases is a great idea to streamline the process.
