Follow the trail from foundational concepts to practical engineering decisions.
The Adapter pattern converts a legacy API's interface into a protocol expected by new code. This guide covers how to create a conversion boundary in Swift, simplify replacement and testing, and distinguish it from other wrapping patterns.

For developers using a Mac, the terminal is probably the app they keep open the longest each day. Yet surprisingly, many people keep using the default Terminal for years.

In Part 3, we saw how to clear conversation history with /clear. But checking the remaining context immediately afterward shows it is not at 100%. Run /context in Claude Code and the reason becomes clear: the system prompt, tool definitions, CLAUDE.md, and tools registered by MCP servers already consume tens of thousands of tokens…

In Part 1, we saw why the context window is finite. But looking at today's model specs raises a question: models with 1 million tokens already exist, so why not just feed in the entire codebase or document? Is there any point in being careful?

The previous two posts completed the diagnosis. The context window is finite (Part 1), and filling it does not mean everything is used; performance actually declines as it grows (Part 2). The prescription is clear: manage context. Coding agents, including Claude Code, provide /clear and /compact for this purpose…
