AI coding prompt templates
Starting points for tasks CodeLazr measures well on - copy one, swap the brackets, paste into the editor. The same list is one click away from the composer itself.
How to use these templates
Replace every [bracket] with something specific: the exact function, file, error message, or rule. Specific prompts matter more than clever wording - in our tests a detailed, task-specific request finished up to 2x faster than a vague one, while a generic "plan first" step made results worse. Keep each request to one clear goal; single-goal tasks like fixing a bug or writing tests succeed 90-100% of the time across nearly every model we test.
Which model to use
For everyday tasks, free OpenRouter models are often enough: in our 10-task benchmark, Laguna M.1 (free) got 7 of 10 right on the first try and North Mini Code (free) was the fastest, with automatic retries taking every free model to 10/10. See the full results in the top 10 tasks case study.
