10-Step Blueprint: Make Coding Agents 200x Faster, 400x Cheaper
blaizedsouza · x · 2026-09-22
Diogo Amogo, founder of Jev, released a 12-page PDF blueprint for building a coding-agent harness. Key points: assume no KV cache when designing; blind model routing backfires (Opus→Sonnet→Opus costs 6.19 vs 4.15 for pure Opus due to context reprocessing); reading/searching consume 56.2% of tool turns and 46.5% of tokens while writing code is under 10%; score each context chunk per query (hide/short/long/full) and compress after the question, not before; disclose tools in tiers.
