Why Faster AI Made Me Busier—and How Four “Digital Senior Employees” Solved It

After weeks of using AI to speed up work, the author found the tool made reviews and incident handling more exhausting, until a structured set of four AI‑driven “digital senior employees”—code map, development workflow, log‑analysis, and data‑verification skills—provided global context and reliable evidence, dramatically reducing busy‑work.

How One Backend Serves Three Audiences: OpenAPI, CLI, and Frontend

The article walks through a real‑world agent platform backend, showing how the same OpenAPI contract is split into three distinct faces—OpenAPI for developers, a CLI for AI agents, and a web frontend for humans—detailing the architecture, lifecycle, command tree, and two concrete pitfalls with code examples.

Design Retrospective: Splitting Tools and Delegating Judgment to AI

The article analyzes nine pitfalls encountered while building a CLI tool for AI, derives a core principle of separating deterministic execution from ambiguous judgment, and presents concrete design rules, a skill‑packaging approach, and two real‑world case studies that illustrate the solution.
