AI Agent2026
Provides a ruleset and skills that make AI coding agents prefer the simplest correct implementation: reuse existing code, prefer stdlib/native features, and only write minimal new code. Cuts generated LOC, tokens, cost and time while preserving validation and safety.
AI Coding2024
Runs a coding agent across VS Code, JetBrains, terminal, SDK, CI, and chat channels. Its main bet is portability: many model providers, human-approved steps, MCP tools, and Apache-2.0 code.
AI Coding2025
Runs model-agnostic coding agents inside VS Code for code generation, refactoring, debugging, docs, repo Q&A, terminal/file workflows, MCP, and custom modes. The original extension shut down on May 15, 2026, so treat it as an archive or fork baseline.
