All questions
What are the best prompt engineering tools?
You’ll likely need: (1) a prompt library with versioning, owners, and changelogs; (2) an evaluation harness to score accuracy, formatting, tone, and safety; (3) experiment tracking for A/Bs; (4) telemetry for cost/latency; and (5) lightweight data stores for examples and rubrics. If your stack uses RAG or tools, include a retrieval debugger. ‘Best’ means what you’ll actually use daily—simple, scriptable workflows usually beat heavyweight platforms for small teams.
In practice
Start with a spreadsheet + scripts. Only upgrade when your experiments outgrow them.
Where to start
- 1Stand up a git-backed prompt repo with owners and PRs.
- 2Create a small eval set and automate daily scoring.
- 3Log cost and latency for every production call.
- 4Add a retrieval inspector if you use RAG.
