Building an Interview Coach with Claude Code
A developer built an open-source interview coach using Anthropic's Claude Code to enforce a strict teaching workflow and cross-session memory. The system uses CLAUDE.md rules files plus a persistent memory to hardcode pedagogical steps: strict question sequencing, mandatory explanations for wrong answers, verification questions, and forgetting-curve review scheduling. The tool also provides a daily wrap-up (Feynman-style) and can generate follow-up questions from the user's own project code. The project repository (happiness-cheng/ai-interview-engine) is available on GitHub. The article was published on 2026-05-30.
Demonstrates a practical developer use of LLM features (programmable rules + memory) and an open-source implementation, relevant to AI tooling but not industry-shifting for AdTech.

Developer First Look: Anthropic's Claude Code
This developer-first look examines Claude Code, Anthropic's terminal-based, agentic coding tool. Unlike chat interfaces, Claude Code reads project folders, edits and creates files, runs shell commands, and preserves project context via a CLAUDE.md briefing file. The author walks through installation, trust prompts and permission modes (Default, Auto-Accept Edits, Plan), model selection (example: claude-haiku-4-5), and configuration commands (/model, /config). Key features highlighted include an @ folder reference system for pulling content from project files, session tools (/cost and /context) for monitoring tokens and spending, and a permission workflow that proposes diffs before applying changes. The tutorial builds a portfolio site almost entirely with Claude Code at a reported cost under $0.10 and notes best practices for scoping the tool to a project folder and using CLAUDE.md for team conventions.

AI Educator Shows Claude Code Business Workflows
Grace Clarke, an AI educator and former marketing consultant, describes how she taught herself Claude Code and built a curriculum and business tooling on top of it. She uses Claude-based tools — including an hourly pipeline operator, an interactive HTML proposal maker, a voice-guide skill file to keep outputs in her voice, and a custom Gmail replacement built via Cowork — to run her service business. The interview/case study covers her workflow, handing off Claude sessions as Markdown to Cowork, her focus on “intent engineering” over prompt engineering, and everyday Claude use for tasks like workout tracking and plant care.
Claude Code Best Practices: From Vibe Coding to Agentic Engineering
This article (No. 35 in an open-source series) profiles shanraisshan/claude-code-best-practice, an open-source reference library that documents workflows and conventions for using Anthropic’s Claude Code CLI. The guide synthesizes official Anthropic guidance and community practices to promote "agentic" or AI-native development, with recommended artifacts such as CLAUDE.md, Skills, Hooks, Commands, and strategies like phase-gated planning, parallel Git worktrees, and cross-model review agents. It lists practical tactics (start with /plan, manual /compact when context is high, use conditional <important> tags), targeted audiences (AI-native developers, team leads, hardcore Claude Code users), and project metadata (approx. 1k GitHub stars, ~150 forks, CC0 license). The piece is a developer-focused technical spotlight rather than commercial news and emphasizes reproducible, architecture-driven workflows for building multi-agent code pipelines.
