This is genius. I cut my agent's cost per code review by 49% with one simple setup change. Cloudflare published how they took their AI code reviewer from $2.43 to $0.77 per run. 77% of their bill was the cache. The shared prompt never got cached because per-job details sat in the same block. The fix: static part first, dynamic details after, and cut wasted calls. I tested it on 5 real FastAPI pull requests with Claude Code: > Moved the rules into a stable prompt. Branch and date go after the diff. > Cut tools from 16 to 4 and dropped unused MCP connectors. > No final summary. $0.144 → $
