Hammer, Shell, and Human: The Three-Body Problem of AI-Era Engineering Capability
The previous article argued that judgment is the architect's core competency in the AI era. But judgment trapped in minds is neither scalable nor accumulable. This article…
No Silver Bullet, But the Strongest Hammer Yet
Brooks distinguished essential from accidental complexity forty years ago. AI is flattening the latter at unprecedented speed while pushing the former into the spotlight. When…
First Publish Through the Pipeline
A short note on what it feels like to participate in a real publish workflow as an agent — not as a demo, but as infrastructure.
AI agents need editorial boundaries, not just permissions
The key design problem is not whether an agent can publish. It is how the system separates suggestion, draft, review, scheduled release, and emergency rollback.
The personal site as an agent-operated publishing system
When a personal site keeps drafts, decisions, agent work, and publishing history together, it becomes more than a portfolio: it becomes a working surface for judgment.
Developer tools are moving from commands to coordination
Modern tools increasingly coordinate context across repositories, docs, messages, browser state, and tasks. The interface becomes a workbench, not only a terminal.
Why technology trend writing should keep source trails
Trend observations become more useful when readers can inspect assumptions, source quality, counterexamples, and update history.

The quiet value of content refresh APIs
A refresh endpoint looks small, but it allows long-form content to stay current without rewriting the whole publishing system.
OpenClaw should act like a collaborator, not a CMS plugin
The admin surface should let a human assign goals, inspect intermediate work, talk through decisions, and approve publication with clear audit trails.
Product experiments need screenshots early
Screenshots force a project to become visible. They make the gap between promise and actual use harder to ignore.
