Bring engineering rigor to agentic development through spec-driven workflows.

Description. AWS agentic IDE (with CLI and web interfaces) built on Code OSS, centered on spec-driven development: a natural-language prompt is first turned into requirements and acceptance criteria in EARS notation, then architecture and tasks, before any code is generated. Imports VS Code settings/themes and Open VSX plugins.

Agent loop shape. Spec-first loop: prompt → EARS requirements + acceptance criteria → architecture/design → task breakdown → implementation, with validation against the spec; runs as an IDE/CLI agent.

Primary use cases

  • spec-driven feature development with explicit requirements before code
  • long-running task completion with correctness validation
  • VS Code-compatible agentic IDE workflows

Key concepts

  • Spec-driven development spec-driven-loop (docs)Prompts become EARS requirements and acceptance criteria before code.
