Prompt engineering shapes how you ask — clear instructions, examples, structure, and constraints — to steer a model toward correct, consistent results. It is the cheapest tuning lever and often the first thing to try before fine-tuning.

AI for Video: A Complete Guide to Intelligence in Video Products: From Real-Time Pipelines and Agents to Serving, Cost, Compliance, and Verticals
Prompt engineering is the first lever for an agent that misuses tools or drifts off task, long before fine-tuning. This volume covers prompt engineering as part of agent engineering: tool use, memory and planning primitives, frameworks, eval rigs, and the cost of running agents in production. Written by Nikolay Sapunov, CEO at Fora Soft.
Can prompt engineering fix your agent before you commit to fine-tuning?
Send us failing agent runs, and we will rework prompts, tool descriptions and checks and report success rates before and after. 250+ video products shipped since 2005.
