Task specs
What the model must do, with examples of done and not-done.
Need prompt engineering talent who can make an LLM feature reliable enough to ship? Growwr helps you discover verified specialists with evals, tooling, and product-integration evidence.
Prompt engineering is product work: specs, retrieval, eval sets, and failure modes — not a secret phrase. Specialists on Growwr have designed assistants and extraction pipelines with regression tests, and they have said no when the model hallucinated in a way legal would not accept. Hire someone who has an eval harness, not someone who only tweets prompts.

What the model must do, with examples of done and not-done.
A set you re-run when you change the prompt, model, or retrieval.
Retrieval and function-calling designed so the model is not guessing.
Jailbreaks, PII, and “I don’t know” paths that product can live with.
Model choice and caching that match the UX budget.
UX around uncertainty — citations, edit, and human review.

The title is noisy. The work — evals, specs, retrieval — is real. Hire evidence, not the label.
Yes. Scope should include evals and a kill switch, not only a demo.
If you are serving models, fine-tuning, or high QPS, yes. Many prompt specialists pair with platform engineering.
