Point at the File. Don't Describe It.
"The auth helper, I think it's somewhere in src/utils, it handles tokens": and now it's grepping around, burning context to find something you already know the location of.
Reference it directly with an @ path and it reads the file before responding. Drag a screenshot straight into the prompt. Drop a documentation URL and let it fetch.
Precise references mean context gets spent on the right files instead of the search for them.
And install the CLI tools. In my experience gh and friends are the most context-efficient way to reach an external service: one command replaces a page of explanation.
