What Semantic Kernel is for
Semantic Kernel is one of 68 tools in our AI Agents & Agent Frameworks list. Microsoft's SDK for AI agents in C#, Python and Java.
Agents pursue a goal across several steps, using tools such as browsers and APIs rather than answering a single prompt. Products range from ready-made assistants to developer frameworks for building your own.
What to check before choosing Semantic Kernel
- Oversight: logs of each action and approval steps before anything irreversible.
- Cost predictability, since a long run can consume many model calls.
- Tool permissions that can be scoped down for each task.
Agents can be misled by instructions hidden in the pages and files they read. Limit their access, and start with tasks where a mistake is cheap and easy to undo.
