https://frankencoder.com/blog/ Practical, measured guides to coding with AI agents: context economics, agent orchestration, and what a session actually costs. en-us Tue, 16 Jun 2026 00:00:00 GMT https://frankencoder.com/blog/context-economics.html https://frankencoder.com/blog/context-economics.html Sat, 14 Jun 2026 00:00:00 GMT Where the money actually goes when you code with an Anthropic-powered AI agent — measured across 340,000 messages and 600+ real coding sessions — and why cache writes, 5-minute TTLs, keep-warm, and shared prefixes change the cost math. https://frankencoder.com/blog/delegation-economics.html https://frankencoder.com/blog/delegation-economics.html Sat, 14 Jun 2026 00:00:00 GMT We replayed 104,979 real agent turns with their actual token bills. Keeping the smart model planning and verifying while cheap sub-agents do the search-and-edit grunt work cut cost ~43% on real code-heavy sessions — measured by replaying billed history, not a synthetic benchmark.
