Microsoft Copilot Studio Adds Scriptable Skills
The article explains how the new Copilot Studio (Microsoft) exposes Skills—Markdown-based modules (typically named skill.md with YAML metadata)—that function as plug-ins and can include Python scripts and templates. Skills, a concept originating at Anthropic, enable better context management, transferable prompt modules, deterministic outputs via scripts, and consistent templated responses. The author outlines three skill types (behavioural, action, knowledgeable), ways to invoke skills (Instruction, Description, From a Skill), and practical patterns for passing data to and from embedded Python scripts within Copilot Studio.
Microsoft's Copilot Studio adding scriptable, template-backed Skills (plugins) with built-in Python support materially improves developer/agent workflows, deterministic outputs, and enterprise automation—relevant to AI-driven tooling adoption.

Key Takeaways & Evidence Grounding
- Copilot Studio exposes Skills implemented as plug-ins that can include skill.md files, scripts, and other tooling.
- Skills are Markdown files with YAML metadata (commonly named skill.md) that provide modular prompts/context.
- Anthropic originally created the Skills concept (associated with Claude).
- Copilot Studio includes a built-in Python compiler so Skills can run Python scripts to produce deterministic outputs and exchange data via files or stdout.
- The article defines three skill types (behavioural, action, knowledgeable) and three invocation patterns (Instruction, Description, From a Skill).

Microsoft Launches New Copilot Studio Preview
Microsoft has released a redesigned Copilot Studio in preview, migrating the backend engine and replacing legacy 'topics' with an LLM-driven model centered on 'Skills'. The new builder emphasizes six areas including Microsoft IQ (Work IQ, Fabric IQ, Foundry IQ), Skills, Tools (connectors), Knowledge, Connected Agents, and Memory. The preview improves UI/UX, a richer preview/test experience showing agent reasoning, and introduces Workflows replacing Agent Flows. Current limitations in preview include restricted knowledge source types (external sites, SharePoint, OneDrive) and limited solution/export access.
Make AI Skills Persistent for Agentic Workflows
The article explains that AI "Skills"—small, shareable files that codify procedures—have shifted from a personal prompting shortcut to an organizational, agent-invoked standard. Anthropic added Skills into Excel and PowerPoint sidebars on March 11; the skills format has been adopted across vendors (OpenAI, Microsoft, GitHub, Cursor) and the author says ~500,000 skills now run interoperably. Key changes: agents call skills autonomously, admins can provision skills across organizations, and the same skill files run in developer terminals and productivity apps (M365). The author outlines architectural patterns (progressive disclosure, specialist stack, orchestrator), explains why conventional skill design fails for agentic use, prescribes five elements every skill body needs, and offers four prompts and practical tests to make skills agent-ready. The piece also includes access to a skills repository and team-deployment guidance.
Open Skills Library: Making Agent Workflows Portable
A Substack essay argues that AI agent 'skills'—the procedural knowledge encoded as prompts, runbooks, SKILL.md files and configs—are becoming trapped inside vendor tools (Claude, Codex, Cursor, ChatGPT), creating repeated rebuild costs when teams switch platforms. The author launches "Open Skills," a public library of agent skills and runbooks designed to be visible, movable, inspectable and installable across tools. The piece explains how skills differ from memory and prompts, lists four failure modes that create long-term debt, provides a "work package" checklist to prove ownership of a skill, and demonstrates rebuilding a support-billing workflow that travels across Claude Code, Codex and Cursor. The author frames skill portability as practical work for 2026 that avoids new subscriptions by making existing workflows portable.
