Claude Code Mastery

12 articles to make Claude Code your second brain in the terminal — from one-shot Q&A to multi-agent pipelines that ship features end to end.

  1. Part 01Claude Code vs ChatGPT vs Copilot vs AgentsMost developers are using the wrong AI tool for the wrong job. Here is why — and what to do instead.
  2. Part 02Installation + The Antigravity WorkflowInstalling Claude Code is a 30-second job. Setting up the workflow that makes the agent feel like it's doing the heavy lifting — that's the part nobody writes about.
  3. Part 03Writing Prompts That Work"Make it better" is not a prompt. "Refactor this for performance" is not a prompt. Here is the four-part structure that makes Claude Code actually finish what you asked.
  4. Part 04Slash Commands — Building a Project from A to Z/init, /agents, /compact and your own custom commands. The toolkit that lets you go from empty folder to running app without leaving the Claude prompt.
  5. Part 05Sub-Agents — The 11 Specialized Experts Inside Claude CodeSlash commands reuse prompts. Sub-agents reuse whole personas — code-reviewer, test-writer, migration-runner. Here is the team you should have on day one.
  6. Part 06Production Codebase SafetyPermissions, guardrails, and what not to automate. The unsexy article that decides whether Claude Code becomes infrastructure or becomes the reason you got paged at 2 AM.
  7. Part 07Multi-Agent PipelinesChaining sub-agents, running them in parallel, and the patterns for 'review-while-coding' without losing your mind. Where Claude Code starts to feel like a small engineering org.
  8. Part 08Building Complete FeaturesFrom Linear ticket to merged PR with Claude Code. A real, honest walk-through — what the prompt looked like, what the agent got right, what I caught in review.
  9. Part 09Testing and DebuggingLetting Claude Code own the entire test loop. Including the parts that make engineers nervous: regressions, flakies, integration tests, and the stack-trace whisperer.
  10. Part 10Team WorkflowsHow engineering teams are actually integrating Claude Code today. The shared .claude/ folder, the review rituals, and the anti-patterns I keep seeing in the wild.
  11. Part 11Advanced Patterns — Hooks, MCP Servers, Custom Tools, System PromptsOnce you've outgrown the defaults: hooks for deterministic side effects, MCP servers for org-specific data, custom tools, and system-prompt surgery.
  12. Part 12The Future of Agentic DevelopmentWhere this is going in 2026 and beyond. What I'd bet on, what I would not, and the line where I get sceptical of the hype.
