The 30-second answer: MCP (Model Context Protocol) is an open standard published by Anthropic that unifies the way AI agents connect to external tools and data. It bundles the integration work you used to wire up separately for each tool into a single spec, so a connection you build once can be reused across many … Read more
The 30-second answer: An AI coding agent takes a different path every time, even given the same input. There is randomness on every call, and small differences get amplified as several tools are chained together. So you have to judge it by statistics gathered over many runs, not by a single execution — and that … Read more
The 30-second answer: An AI coding agent ignores your project rules not because you wrote a bad prompt, but because it’s guessing without knowing your codebase’s structure, conventions, and prohibitions. The practice of organizing that information is context engineering, and the file that has become the de facto standard for holding it is AGENTS.md. You’ve … Read more
Hooks are lifecycle shell commands you define in .claude/settings.json. Unlike CLAUDE.md instructions, which the LLM sometimes skips, they enforce a specific action deterministically. PreToolUse handles validation and blocking before execution; PostToolUse handles formatting and testing after execution. (Per the official docs.) I’m a solo developer who has run an automation pipeline called NABERAL on top … Read more
The 30-second answer: The three layers that extend Claude Code play different roles. Skills are a lightweight extension that pulls in task-appropriate instructions on demand; subagents are a heavier helper that runs isolated and in parallel in a separate context; hooks are a deterministic safety net enforced by a shell script rather than the LLM. … Read more
At a glance: A Claude Code subagent is a specialized Claude instance with its own context window, a dedicated system prompt, and a scoped tool list. You define it as a Markdown file in the .claude/agents/ folder and manage it with the /agents command. It solves the problem of ballooning context through isolation, and it’s … Read more
Do your AI answers keep coming out mediocre? It’s not that the AI is dumb. Nine times out of ten, the problem is how you’re asking. With the same ChatGPT and the same Claude, one person pulls out brilliant results while another gets the same bland, obvious answers and thinks, “What is this?” The difference … Read more
In short: OpenCode is a free, open-source AI coding agent that runs in the terminal and routes more than 75 LLM providers through a single interface. In LogRocket’s June 2026 power rankings, OpenCode placed first, Cursor second, and Claude Code third. Vendor neutrality and cost are the core differences. At NABERAL Lab we run our … Read more
HOW TO ACTUALLY USE AI · CLAUDE.md How to Win an AI Coding Contest Without a Line of Code The winner wasn’t a developer — it was a lawyer. The secret wasn’t coding but a single ‘instruction sheet’ handed to the AI. That is exactly CLAUDE.md. “I can’t believe I won this contest — and … Read more
July 2026 update — This guide was written in early June 2026, right after Opus 4.8 launched. Since then, Anthropic has released the Claude 5 family (Fable 5), and Claude Code’s default model has changed to Sonnet 5. The differences between Opus 4.6 and 4.8, and the migration checklist below, remain valid; for the latest … Read more
