Claude Code prompt engineering gets leaner as teams strip away most of the system prompt
A post summarizing an article on the new rules of context engineering for Claude 5 models says one team removed about 80% of the Claude Code system prompt for its newest models.
The takeaway is not just “use a shorter prompt,” but that skills, Claude.md files, and iterative discovery matter more than stuffing instructions into the system prompt. The article frames this as a practical shift in how developers should structure context for newer Claude models when building agentic workflows.
