Prompts and habits that make an AI coding assistant worth its latency
AI coding assistants are strongest with context and weakest with assumptions. Most of the skill is in what you give them before you ask.

Give context first
Name the language, framework and version — Half of all wrong answers are right answers for another version
Paste the real error, in full, including the stack — A paraphrased error loses the line that mattered
Show the surrounding code, not just the broken line — The bug is usually not where the exception surfaced
Say what you already tried and what it did — Otherwise the first suggestion is the thing you tried
State the constraint — no new dependencies, must stay sync — Unstated constraints are violated by definition
Request patterns
Goal
Ask for
Understanding code
"Explain what this does and name any edge case it mishandles"
A bug you cannot see
"List three possible causes, most likely first, and how to test each"
A refactor
"Refactor for X only. Change nothing else and keep the signature"
Tests
"Write tests for the boundaries and failures, not the happy path"
A review
"Review this as a hostile reviewer. What breaks in production?"
Review it like a stranger wrote it
Generated code is fluent, which makes it read as reviewed when it has not been. Check three things specifically: invented API methods that do not exist, error paths that silently swallow, and dependencies added without being asked for. Fluency is not correctness, and confident code is the hardest kind to review.
FAQs
Why does it suggest APIs that do not exist?
It is completing a plausible shape rather than recalling a specific library version. Naming the language, framework and version in the prompt removes most of it; the rest is caught by actually running the code.
What should I never delegate?
Anything you cannot verify quickly. If reviewing the output costs more than writing it, the assistant has moved work rather than removed it.
