Prompts as Code: Maintain Your AI System Like Software
Prompts that live in a prompt and evolve in a slide deck are liabilities. Version, test, and review prompts like software — because they're now software.

A prompt that only lives in your memory or in the chat where you tuned it is a bug factory waiting for a deploy. Prompts that drive features belong in a repository, under version control, with tests — because they're now the software.
Store Prompts in the Repo, Not the Chat
Prompts that matter live as versioned files or database rows next to your code, not as copy-pasted chat text. Every change gets a diff; every deploy gets a record. This is the maintainability half of prompt engineering, and it matters most once the prompt drives a production feature.
Build an Evaluation Set, Tune on Evidence
Keep twenty to fifty representative inputs with expected behaviours, and run them against every prompt change. 'Better prompt' becomes a measurable regression test instead of a gut feel. The discipline mirrors verification: you judge the output, the set judges the prompt.
Review Prompts With Two Pairs of Eyes
Prompt drift happens quietly — a small tweak that changes tone, scope, or safety across everything downstream. Review prompt changes like code changes: another engineer reads the diff, tests run, and merges happen deliberately. Pair the review with a strong base model such as Claude API for the passes that matter most.

Final Thoughts
Prompts are code now: version them, test them, and review their diffs. An evaluation set plus a repo turns prompt tuning from folklore into an engineering loop.
