The fundamentals of Agentic Coding (AKA Vibe Coding)
summary
Claim: the model is the brain (about 95% of capability) but the crucial engineering work is the harnesses that let text-only models actually act. Demo uses the OpenAI JavaScript SDK pattern: declare function tools (read files, run tests), model returns intentions, harness executes and feeds results back, enabling automated test runs and code edits. AgentsMD/skills are just injected markdown docs; diagrams come from generating markup. Closed cloud-code locks the harness; pick one openable harness and iterate.
