A developer built 10 single-purpose AI automation agents in pure Python, each 15-30 lines of core logic, after abandoning LangChain, LangGraph, CrewAI, and Zapier. The agents run on macOS via launchd using a fetch-reason-push pipeline with a three-tier AI fallback: Claude API, Ollama local, or ra...

A technical comparison of four AI coding tools finds Claude Code and Gemini CLI operate as terminal agents, Cursor integrates with VS Code, and Codex focuses on automated task execution. All four store session history as JSON files with no cross-project search or cross-session memory.

A developer built an E2E test generation system using Claude Agent SDK with two MCP servers — one for reading codebase files and one controlling a live Chromium browser via Playwright — so the model inspects actual DOM elements before writing test selectors rather than guessing them.

Claude Code stores conversation history as JSON files in ~/.claude/projects/ (macOS/Linux) or %USERPROFILE%\.claude\projects\ (Windows), with filenames based on hash strings that carry no semantic information. The tool lacks a native interface for browsing or searching past sessions across projects.
