A practical guide to using PromptHub (PromptLayer's prompt management system) as a full control plane for LLM teams. Covers structuring prompts with variables and output contracts, maintaining version history with meaningful release notes, building test suites of 20–50 cases before promotion, enforcing draft/staging/production environments, logging prompt-version IDs on every request for debuggability, connecting evaluations to each prompt, and feeding production failures back into test datasets. Includes a 10-step repeatable workflow and a list of common mistakes to avoid.
