Functional Programming in TypeScript

Functional programming is not academic mysticism. It makes code more predictable, testable, and less error-prone. This guide covers practical FP in TypeScript: pure functions, immutability, composition, map/filter/reduce, Option/Either for null values and errors, and why pragmatic FP matters more than monad dogma.

Design Partner Charters: Bilateral Commitments, Scope Changes, and Expiry Evidence

A design partner saying they will collaborate is not the same as delivering data on time, reviewing results, or accepting deliveries. This article freezes both sides commitments, scope boundaries, and acceptance evidence into a versioned charter, using change and expiry states to stop pilots from dragging on indefinitely.

Context Engineering: Giving the Model the Right Information

The prompt-engineering era is yielding to context engineering: prompts care about 'how to say it,' context cares about 'what to show the model.' This article covers four context types, window-management strategies (priority/compression/forgetting), and how to build an Agent's context—its ceiling usually depends not on model strength but on what you feed it.
