LangChain — moat

LangChain, Harrison Chase's framework for LLM integration, finds itself in a multi-front competitive battle. The graph shows it competes directly with DOVA and Claude Code, while also being both used by and competing against GitAgent—a tense dual relationship. LangChain has shipped two key products: LangGraph and Deep…

Frequently Asked Questions

What is CLAUDE.md and how should I set it up?
CLAUDE.md is a project-level instruction file that Claude Code reads at the start of every session. Place it in your project root with coding standards, architecture decisions, tech stack info, and workflow preferences. It acts as persistent memory so Claude understands your project without re-explaining every time.
How do I reduce Claude Code costs?
Use Haiku for simple tasks (search, file reads), Sonnet for code review, and Opus only for complex architecture. Write a good CLAUDE.md to reduce re-prompting. Use /compact to manage context window. Batch related changes in single sessions instead of many short ones.
What are MCP servers and which ones should I use?
MCP (Model Context Protocol) servers extend Claude Code with external tools — database access, browser automation, API integrations, and more. Popular ones: Chrome DevTools for visual testing, GitHub for PR management, PostgreSQL for database queries. Configure them in .mcp.json in your project root.
How do I use Claude Code for agentic workflows?
Use the Agent tool to spawn sub-agents for parallel tasks. Create specialized agents with custom system prompts. Use hooks (PreToolUse, PostToolUse) to automate formatting, testing, and validation. Set up CLAUDE.md with delegation rules so Claude routes tasks to the right model tier.
What's the difference between Claude Code and Cursor?
Claude Code is a CLI-first agentic coding tool that runs in your terminal with full system access. Cursor is an IDE with AI built in. Claude Code excels at autonomous multi-file changes, complex refactoring, and DevOps tasks. Cursor is better for inline code completion and visual editing. Many developers use both.
How do I use hooks in Claude Code?
Hooks are shell commands that run before/after Claude Code actions. Configure them in .claude/settings.json under the 'hooks' key. Common uses: auto-format code after writes (PostToolUse on Write|Edit), run tests after changes, log bash commands, validate security. Hook types: command, prompt, and agent.
