Anthropic Engineer Demonstrates How He Uses Claude
Felix Rieseberg, engineering lead for Claude Cowork and Claude Code Desktop at Anthropic, appears on the How I AI podcast to demonstrate practical Claude workflows — turning emails into a 3D floor planner with real furniture, using email as a personal inventory database, building live dashboards via connectors, creating a $20 hardware “Claude buddy,” and discussing model-selection heuristics (Sonnet vs Opus) and debugging workflows. The newsletter episode also summarizes Google I/O 2026 launches: Gemini 3.5 Flash (claimed to rival frontier coding models and run four times faster), Antigravity 2.0 (IDE updates including projects, scheduled tasks and subagents, plus a /grill-me command), Google AI Studio, Omni and Flow for longer-form multimodal video production, and design/marketing tools Stitch and Pomelli. The coverage highlights Gemini’s multimodal strengths and notes many announced Google features were not fully functional in live tests. Publication date: 2026-05-25.
Provides practical demonstrations and product insights about Anthropic's Claude features useful to developers and product teams, but it is an informational podcast episode rather than an industry-changing product launch or policy update.

Boris Cherny Explains Building Anthropic's Claude Code
Boris Cherny, creator and Head of Claude Code at Anthropic, discusses how Claude Code evolved from a side project into a core internal developer tool and the engineering practices that enable agent-driven development. He describes a high-velocity workflow (running multiple parallel Claude instances to produce many PRs per day), retrieval strategies (simple glob/grep driven by the model outperformed more complex RAG/indexing approaches), and deterministic review and sandboxing patterns used to manage safety. The episode also covers Claude Cowork — a VM-based desktop agent built rapidly to serve non-engineers — and organizational shifts: prototypes replacing PRDs, automation of repetitive code-review comments, and a changing skills profile for engineers as agentic tools handle more of the implementation work.
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.
Using Claude to Automate Shopping and Returns
A June 8, 2026 episode of the How I AI podcast (host Claire Vo) features Nicole Ruiz explaining how she uses Anthropic’s Claude and Claude Cowork to build an AI-powered shopping system. Ruiz describes creating a "Claude Project" with custom vetting rules to surface long-lasting, heritage brands, using Claude to search poorly designed vendor sites, automating returns by finding receipts and drafting refund requests via Claude Cowork, and shopping within budgets or gift-card constraints. The episode highlights how conversational LLMs can reduce household administrative burden and help small artisans compete with large marketplaces.
