2. Design note Observation **Let the model see the result** An agent needs observations it can inspect again, especially when its first explanation is wrong. Sep 12, 2026 3 min read [Let the model see the result](https://www.plazor.xyz/blog/let-the-model-see-the-result)

3. Design note Systems **Stages small enough to test** A pipeline can have correct components and still produce the wrong answer. The boundaries deserve their own tests. Aug 03, 2026 3 min read [Stages small enough to test](https://www.plazor.xyz/blog/stages-small-enough-to-test)

4. Design note Interfaces **A face for a program** A small face can make an interface feel present. It also creates an obligation to separate expression from evidence. Jun 21, 2026 3 min read [A face for a program](https://www.plazor.xyz/blog/a-face-for-a-program)
