context engineering
Select and maintain the information an agent needs for the current task.
Use this when The agent keeps overlooking repository rules or working from obsolete assumptions.
without the term
“You keep forgetting our rules and working from old assumptions. What should I give you at the start so you have the right files, the actual error, and the constraints, without dumping the whole repo?”
with the term · How do you ask a model for context engineering?
Prepare the context for this fix: requirement, relevant files, exact failure, and constraints. Identify missing evidence before editing.
What is context engineering?
You choose what the agent sees: the requirement, the relevant code, the exact error, and lasting decisions. Then you keep it current as the task changes, instead of pasting everything.
Why does context engineering matter when vibe coding?
More context can bury the evidence needed for the next decision.
How do you do context engineering?
Provide the requirement, relevant code, exact failure, and durable decisions; refresh them when context changes.
What goes wrong with context engineering?
Restricting context so tightly that a relevant caller is never inspected.
