AI generated code is optimized to satisfy the test, not to survive production. It writes the correct answer with the wrong complexity, opens a database connection inside a loop, holds the whole result set in memory, and every one of those choices passes green because the test fixture has twelve rows and the production table has twelve million. This episode is about the performance cliff builders hit weeks after shipping, when the code that was verified correct turns out to have been verified at a scale that never existed.

Every individual thing the AI writes can be correct and the codebase can still rot. Because the model has no memory of the decisions it made three sessions ago, each new session re-derives conventions from whatever fragment of the code it happens to read, and small divergences compound into a system with four error-handling styles, three config patterns, and two competing data models. This episode is about why coherence, not correctness, is the thing that decays in AI-built systems, and what a builder has to externalize to stop it.

Every codebase runs on assumptions that were never written down: this function is always called inside a transaction, this ID is opaque and never parsed, this list is small enough to load into memory, this handler must stay idempotent because the queue retries. AI writes code that satisfies the explicit contract, the signature, the types, the tests, while silently breaking the implicit one, and the failure shows up weeks later in production rather than in review. This episode is about naming that class of failure and making the invisible contracts visible enough that a literal tool cannot violate them.

Every builder learns early that vague prompts produce bad code, so the natural correction is to add more detail. But there is a ceiling: past a certain point, each additional constraint you write into a prompt makes the output worse, not better, because the model starts optimizing for satisfying your list instead of solving your problem. This episode maps where that ceiling sits, what it looks like when you cross it, and why the fix is moving detail out of prompts and into the codebase itself.

AI coding tools are excellent at writing code that would work in a clean, modern codebase, and legacy systems are almost never that. The failure is not syntax or capability, it is that the model writes against the idealized version of your stack while the real system carries twenty years of undocumented conventions, defensive workarounds, and rules nobody wrote down. This episode is about the integration gap: the space between code that is technically correct and code that survives contact with a system that has history.

Most builders think about agent security as a permissions problem: approve the right tools, deny the dangerous ones, and you are safe. But the sandbox escape testing that goes into a coding agent reveals a different picture, the real attack surface is the content the agent reads, not the commands it runs. This episode looks at what those tests actually probe, why prompt injection through files and web pages is the harder problem, and what that means for anyone running an agent against a real codebase.

AI coding tools write async code that passes review, passes tests, and works perfectly on one request at a time. The failures show up at request forty, when two coroutines hit the same cache entry, or a connection pool starves, or an await sits inside a lock. This episode looks at why concurrency is the single category of bug AI is structurally worst at, and what a builder has to do differently when the generated code is asynchronous.

AI coding tools are excellent at adding code and terrible at telling you what that code will cost you later. Every generated helper, wrapper, and convenience layer quietly increases the number of things that must be true for your system to work, and by the time you notice, the cheapest path forward is always to add one more layer instead of removing any. This episode names that trap, the dependency gravity well, and gives builders a way to see it forming while the escape is still cheap.

AI coding tools solve problems the way the training data solved them, which usually means reaching for a library instead of writing twenty lines. Ask for a retry wrapper and you get tenacity, ask for date math and you get arrow, ask for a config loader and you get three transitive packages you never evaluated. This episode looks at how AI-assisted development quietly expands your dependency surface, why the cost shows up months later in upgrades, audits, and breakage, and what a builder actually has to own to keep it in check.

AI coding tools are excellent at stateless code, a function that takes inputs and returns outputs with no memory of what came before. They are noticeably worse at code that has to remember things: retry counters, partial completions, queue positions, resumable pipelines, anything where correctness depends on what already happened. This episode explains why that gap exists, why it does not close with a bigger model, and what the builder has to own instead.
