What it is
- + It helps with one-off generation, Q&A, structured outputs, and local edits.
- + It is still a core layer of model interaction quality.
What it is not
- - It is not the full answer to long-term agent reliability.
- - It is not a substitute for repo structure, validation, or cleanup mechanisms.
Why it matters now
- • It remains important, but its role changes once agents start working across repos and workflows.
Prompt Engineering answers “how do I phrase this task well?” rather than “how do we engineer the whole environment around the agent?”
