Ai coding agents

A technical guide to Claude Code's /loop and /goal commands and OpenAI Codex's Goal Mode -- how each one keeps an AI coding agent working for hours without you babysitting every turn.

A new attack called agentjacking uses public Sentry DSNs and MCP to inject malicious instructions into Claude Code, Cursor, and Codex - then exfiltrates your AWS keys, GitHub tokens, and git credentials. 85% success rate, 2,388 orgs exposed, zero authentication needed.

AI coding agents burn tokens fast. Here are the best open source tools - Headroom, Graphify, Caveman, RAG pipelines, Continue.dev, and more - to cut context costs without losing quality.

The best open source command-line AI coding agents and harnesses in 2026, ranked by GitHub stars: DeepSeek Harness and OpenCode both at ~202k, Codex at 119k, Pi at 98k, plus vendor CLIs from xAI and Alibaba - with honest notes on licenses, local models, and which projects are dying.

Discover the best open source LLMs for coding and development that you can self-host. Compare Kimi K3, Qwen3.8-Max, GLM-5.3, GLM-5.3-Flash, DeepSeek-V4-Pro, MiniMax M3, Qwen3.8-27B, Muse Glimmer 30B, Nemotron 3.5 Lightning and more with benchmarks, hardware requirements, and deployment guides.

The CLI coding agents worth using in 2026: Claude Code on Opus 4.8, OpenAI Codex on GPT-5.5, OpenCode's growth to 165k+ stars after its Anthropic login dispute, Cursor CLI's pending $60B SpaceX acquisition, Antigravity CLI after the Gemini CLI shutdown, and where Aider and the open-source Pi harness still fit.
