Claude Code Review: Agentic Coding Done Properly

Most "AI coding assistant" marketing means the same thing: better autocomplete. Claude Code is one of the few tools in the category that's actually built around a different idea -- an agent that operates your development tools on your behalf, rather than one that just predicts the next few tokens in your file.

How It Actually Works

You run `claude` in a project directory, or open it as a VS Code/JetBrains extension, and describe what you want in plain language: "write tests for the auth module, run them, and fix any failures." Claude Code reads the relevant files, writes the tests, executes them in your terminal, reads the failures, and iterates -- asking for permission before running commands it isn't sure about. That permission-prompt loop is the mechanism that makes it trustworthy enough to point at a real codebase instead of a sandbox.

Subagents Are the Real Differentiator

The feature that separates Claude Code from a chat window bolted onto an IDE is subagents: it can spawn additional Claude instances, each with its own context window and its own set of tools, to work pieces of a larger task in parallel and report a summary back to the lead agent. Practically, that means a large refactor or a "build this feature end to end" request can be split into exploration, implementation, and verification happening concurrently instead of one long serial chat. Anthropic's own Agent SDK exposes the same orchestration primitives if you want to build custom agents on top of it.

MCP, Hooks, and CLAUDE.md

Claude Code leans hard on the Model Context Protocol to reach outside the codebase -- pulling a spec from Google Drive, updating a Jira ticket, or reading a Slack thread without you copy-pasting any of it in. Hooks let you wire shell commands into specific lifecycle events (formatting after every edit, running lint before a commit), which is the kind of deterministic guardrail that pure prompting can't reliably guarantee. And a CLAUDE.md file at the project root, read at the start of every session, keeps it from re-learning your team's conventions and preferred libraries each time -- Claude also writes its own auto-memory as it works.

Everywhere You'd Want It

The same engine sits behind the terminal CLI, the VS Code and JetBrains extensions, a standalone desktop app, claude.ai/code in the browser, and the iOS/Android apps. You can start a long-running task on the web, walk away, and pull it into your terminal later with `claude --teleport`. For teams, GitHub Actions and GitLab CI/CD integration turn it into an automated first-pass reviewer on every pull request.

Where It's Less Comfortable

None of this is free of friction. There's no dedicated ghost-text completion experience -- if what you want is Copilot's inline suggestions while you type, Claude Code isn't built for that. It's also entirely terminal-and-agent-first, which is a genuine adjustment if your muscle memory is built around clicking through suggestions in an editor. And because usage is metered in Pro/Max/5x/20x multipliers rather than a fixed number of completions or messages, it's harder to predict costs than a flat Copilot-style seat price, especially once you start running several subagents on a long session.

The Bottom Line

Claude Code is the most capable agentic coding tool available right now for people willing to work the way it wants you to work -- describing outcomes and reviewing diffs rather than watching autocomplete. For teams that have already standardized on Claude and want deep git, MCP, and CI integration, it's an easy recommendation. For developers who mainly want faster line-by-line completions in their current editor, Cursor or Copilot will feel more immediately familiar.
