What We Lose When Coding Becomes Reviewing
Dax, the creator of OpenCode — an open-source coding agent, of all the people one might expect to disagree — put the case for hand-coding cleanly in a recent interview about Spec-Driven Development:

Spec-Driven Development with OpenSpec
One reason I liked OpenSpec more than others, such as Kiro and SpecKit, is that OpenSpec is highly portable between coding assistants, codebases and stages of development. I've plugged OpenSpec into all sorts of projects, from infrastructure to Python libraries. I also work on diverse codebases, with a variety of AI friends that OpenSpec supports: OpenCode, Codex and Claude Code.

Agentic: Which App/Harness Is Best for Angular Development?
Beyond the big names, I would also keep an eye on OpenCode and T3 Code. OpenCode is a solid open-source, terminal-first option if you want a model-agnostic agent and bring your own provider setup. T3 Code is interesting for the opposite reason: it gives you an open-source GUI on top of the agents you may already pay for, like Claude Code, Codex CLI, OpenCode, or Cursor.

Claude Opus 4.8
It's interesting that (for example for the explore agent https://github.com/Piebald-AI/claude-code-system-prompts/blo... ) they use a personality "you are a file search specialist" and "your strengths" framing. I thought that was largely thought to be useless, or even counterproductive nowadays? Does anyone know more about this stuff?

Claude Code is unusable for complex engineering tasks with the Feb updates
This might be more complex than I imagined. Seems Claude Code dynamically customizes the system prompt. They also update it with every version. Outright replacing it might miss out on updates.

Karpathy on Programming
That refers to the sandbox "escape hatch" [1], running a command without a sandbox is a separate approval so you get another prompt even if that command has been pre-approved. Their system prompt [2] is too vague about what kinds of failures the sandbox can cause, in my experience the agent always jumps straight to disabling the sandbox if a command fails. Probably best to disable the escape hatch and deal with failures manually.
