context engineering
Control what the model can see right now. Only the papers this turn needs stay on the table.
What is context engineering?
Context is not memory. It is a window. Files, errors, and chat all take space. The engineering is selection, clipping, pinning.
Why does context engineering matter when vibe coding?
When the window is full of irrelevant files, the model edits the wrong one, confidently. Failed vibe coding is often failed context, not a stupid model.
How do you do context engineering?
Open two or three relevant files per turn. Paste the full error. Do not pour the repository into the thread. When the thread is long, start another and drop the spec file in again.
How do you ask a model for context engineering?
Look only at these files: (list). Do not read others. The full error is source of truth. Do not edit closed files from memory.
What goes wrong with context engineering?
“Add the whole repo for completeness.” Completeness here is dilution.
