Tutorial: Automate Work with Anthropic's Claude Cowork
JJ Englert of Tenex presents a step-by-step, zero-to-one tutorial on Claude Cowork, Anthropic’s desktop tool for building project-based, LLM-powered automations without coding. The episode demonstrates connecting local folders as projects, creating a persistent "brain" file containing user preferences, and using one-click connectors (Gmail, Slack, Notion, Google Calendar) to enable actions like analyzing sent email to learn tone, drafting but not sending messages, and creating scheduled morning debriefs. Englert also shows a multi-agent "sub-advisory-board" technique for multi‑persona review, permission controls per connector, and argues shared-memory projects yield more consistent outputs than ad‑hoc chats. The episode includes demos, timestamps, and links to supporting tools and documentation.
Practical tutorial on an LLM desktop tool that demonstrates connectors and automation patterns likely to influence productivity and adoption of AI-assisted workflows in marketing and operations teams.

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.
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.

Anthropic’s Claude Cowork Automates Office Workflows
Anthropic released a Chrome extension that embeds Claude as a sidebar inside the Chrome browser, enabling the model to read pages, click buttons, fill forms, navigate tabs, and run scheduled automations. The extension turns recorded workflows into recurring tasks and can operate across multiple logged-in sessions and tabs, enabling use cases such as negotiating a $100 billing credit with AT&T autonomously, organizing 900 Google Drive files, inbox triage, and multi-tab competitive intelligence that can produce structured spreadsheets when paired with Cowork.Build. Developer workflows are supported via integration with Claude Code so agents can write in terminals while the extension tests in the browser. The author notes real-world limitations—particularly for data-heavy tasks that should be split into subtasks—and includes prompts and safety checks for building automations. This follows Anthropic product updates (Cowork features, plugins, scheduled tasks and browser automation) and demonstrates agentic browser automation moving from demo to deployed workflows.
