alt Hacker NewsClaude Code allegedly auto-includes the currently active file and often all visible tabs and sometimes neighboring files it thinks are 'related' - on every prompt.
The advice I got when scouring the internets was primarily to close everything except the file you’re editing and maybe one reference file (before asking Claude anything). For added effect add something like 'Only use the currently open file. Do not read or reference any other files' to the prompt.
I don't have any hard facts to back this up, but I'm sure going to try it myself tomorrow (when my weekly cap is lifted ...).
What does "all visible tabs" mean in the context of Claude Code in a terminal window? Are you saying it's reading other terminals open on the system? Also how do you determine "currently active file"? It just greps files as needed.
