I wanted to generate Adaptive Cards dynamically rather than shipping a fixed card template for every scenario. Using Copilot Studio’s prompt tooling makes it possible to produce card JSON on the fly, adapt to user choices, and even include charts generated at runtime. Quick summary Generate Adaptive Card JSON from a concise prompt rather than maintaining many rigid templates. Keep prompts small: avoid passing too many parameters directly into the prompt.

The June announcement of Copilot Studio’s new experience marks a pivotal shift: Topics and Child Agents are no longer supported. If you’ve architected agents using these approaches, it’s time to embrace Skills as the new standard. Skills fundamentally change how you build agent behavior. Instead of monolithic components, Skills load rich logic on-demand only the Skill name and description are preloaded into the context window, while the full skill executes only when needed.

Copilot Studio now supports Skills as the core way to build agent behavior. With Skills, your agent can load rich logic on demand — only the Skill name and description are preloaded into the context window, while the full skill is fetched only when it runs. Anthropic publishes the Skills collection at https://www.skills.sh. This post covers the skill-creatorskill to help create or modify skills. This Skill helps generate complete SKILL.md packages, including embedded scripts and supporting files.
