Karpathy identified four Claude Code failure modes and built a single CLAUDE.md file that fixes all of them. Here are the four principles — Think Before Coding, Simplicity First, Surgical Changes, Goal-Driven Execution — and how to install them in under 2 minutes.
Karpathy manages multiple Claude Code sessions like a small engineering team — one window per feature, reviewing diffs, merging outputs. Here is the exact 4-step setup, the failure modes to watch for, and the mental model shift from coder to tech lead.
AI coding agents like Claude Code, Cursor, and Windsurf forget everything between sessions because LLMs are stateless by design. agentmemory fixes it in 30 seconds with persistent memory via MCP — here's the full setup, benchmarks, and how it compares to CLAUDE.md and mem0.
Sub-agents let Claude Code run multiple specialized agents in parallel — one searching the codebase, another writing tests, another refactoring. This guide covers when to use them, the Task tool patterns, and the workflows that 3x output.
Claude Code can run $300–500/month per heavy user on the API. These 7 strategies — model routing, prompt caching, context pruning, sub-agent discipline — cut our bill from $480 to $128/month with no quality drop.
Most developers use Claude Code like a chatbot. Here are 10 prompting patterns — with real examples — that turn it into a 10x engineering force multiplier.
Freelancers using Claude Code are billing more, delivering faster, and keeping 100% of the margin. Here's the exact workflow: project setup, client handoff, and where AI saves you the most time.
Middle management is the most AI-augmented role nobody talks about. Managers using AI are running better teams with less effort. Here are the workflows.
Part-time. While running Y Combinator. Garry Tan used Claude Code, gstack, and a multi-agent workflow to ship 600K+ lines in 60 days. Steal his exact stack and mental model.
The old bottleneck was your attention. AI agents change the math — run 10 workstreams simultaneously, make only the decisions that matter, and multiply your output by 10x.
Cursor IDE is the #1 AI code editor. Learn the exact workflows — Tab, Cmd+K, Chat, Composer, .cursorrules, and MCP — that let developers ship production code 10x faster.
Combine Perplexity, Claude, and NotebookLM into a research workflow that turns hours of manual research into structured insights in minutes. The exact stack top operators use.
Stop staring at blank docs. These AI workflows help PMs write sharper PRDs, generate user stories from interviews, run competitive analysis in 20 minutes, and prioritize roadmaps with data.
