Kiro
Let the AI write the requirements first and the code second: Kiro reverses the order. Specs, steering and agent hooks are its core trio, and powers bundle MCP servers with rules into packages loaded only when a task needs them.
Putting the requirements document ahead of the code is what separates Kiro from autocomplete tools. Specs break a request into requirements, design and tasks, steering writes conventions into the project, and agent hooks refresh docs and tests when files change. Powers pack MCP servers and rules into bundles loaded on demand, and the autonomous agent ships sandbox runs as pull requests.
