Claude Haiku 4.5 Adds Skills for Personal Workflows
Anthropic has introduced Skills, a new feature for Claude that lets the AI learn and execute your personal workflows. Skills are repeatable, personalized instructions; Claude automatically detects when a Skill is needed and loads a folder containing guides, scripts, and other resources to perform tasks in the user’s preferred style. Skills can be combined for more complex workflows and are accessible not only in Claude.ai but also via Claude Code and the API. In the settings, users can enable the feature and define their own Skills, with availability limited to Pro, Max, Team, and Enterprise plans. Anthropic also announced a Microsoft 365 integration, enabling Claude to retrieve information from SharePoint, OneDrive, Outlook, and Teams to deliver contextual responses without switching apps. The rollout coincides with Claude Haiku 4.5, which the company claims outperforms Sonnet 4.0 in a software engineering benchmark and competes with GPT-5 and GPT-5-Codex from OpenAI.
New AI feature release (Skills) and Microsoft 365 integration expand Claude’s capabilities; moderate industry impact.

Claude Skills: From Chat Window to Reusable Workflows
This article introduces Anthropic's Claude Skills, a feature that helps users streamline recurring tasks by storing workflow instructions, criteria, and examples. While Skills provide structure and standardize outputs, they do not automate tasks autonomously; users must trigger them. The piece also highlights the Ramp AI Index, which shows Claude ahead of ChatGPT in paid enterprise adoption among US companies. It promotes a t3n online course, 'Claude im Arbeitsalltag,' on September 17, 2026, led by Anna Toklu, founder of JustMarketing Consulting. The course costs €149 and is free for t3n PRO members. Aimed at German-speaking professionals in non-technical roles, the article clarifies when to use Skills versus projects or connectors.
Open-sourced Claude Code Setup and Five Skills
The author (AI by Aakash) published and open-sourced a '0 to 100' starter kit for Anthropic's Claude Code and Claude Cowork, providing two GitHub repositories: pm-claude-skills (five ready-made Claude Skills plus a SKILL-TEMPLATE.md) and pm-claude-code-setup (a CLAUDE.md persistent-context template and a .claude/skills PRD Writer example). The post documents how to import memory from other AI services into Claude using a copy-paste prompt and explains installation steps (git clone and copying skill files). The write-up highlights how skills enforce workflow consistency, describes PRD Writer behavior, and gives practical usage guidance for Cowork and Code. The newsletter also summarizes recent AI industry news (e.g., Google’s Nano Banana 2, Anthropic turning down a Pentagon contract) but its primary announcement is the open-source Claude tooling and setup resources for knowledge-worker automation.
Anthropic's Claude Cowork Learns Tasks by Watching
Anthropic's Claude Cowork adds "Record a Skill", letting users record their screen and optional voice while performing repetitive tasks. Claude analyzes clicks, typing, mouse movements, and spoken instructions to convert the recording into a reusable, automatable skill that can be scheduled as a recurring task. The option appears as "Record a Skill" in the Claude Cowork desktop app's + menu. The feature is rolling out in waves and is available to subscribers on Pro, Max, and Team plans. The announcement was published on DEV Community on 2026-07-22.
