When to prompt and when to code
Built-in tools are tightly coupled and require shipping code directly inside a specific harness. In contrast, MCP servers act as external bindings or cookbooks that let agents interface with data through a generic contract. This abstraction allows external systems to coordinate multiple harnesses without altering their execution logic.
▶ 21:09
My last video about ai harnesses
A product engineer acts as a bridge by connecting a deep understanding of customer needs directly to technical choices.

When to prompt and when to code
Software development has progressively shifted upward through layers of abstraction to eliminate tedious manual work. Developers once worried about low-level instruction sets and syntax, but modern languages, linters, and AI assistance handle those details. Consequently, engineers no longer need to obsess over formatting or memorize fundamental algorithms.

AI agents lack the human judgment to push back on scope creep and will rapidly accelerate bad practices and system bloat throughout a codebase. Because agents execute instructions so quickly, they can easily build the wrong thing at high velocity without pausing to check edge cases or scalability. Developers must actively slow down and exercise systems thinking to wrangle agents and maintain product quality.

TDD, AI agents and coding with Kent Beck
Inference scaling is often more attractive than pre-training larger models because it unlocks substantial performance without the massive upfront fixed costs of pre-training. Developers must weigh the math based on user volume, query costs, and how long the model will remain market-relevant before replacement. While pre-training builds permanent baseline knowledge, inference scaling lets you spend money per query to maximize performance dynamically.
