What it is

Claude Code is Anthropic's official agentic coding tool — not a wrapper, the first-party experience. It reads your whole repo, plans, runs commands, and edits across files while showing you every diff.

It runs on your Claude subscription on the latest Claude models. The thread through every other tool on this page is that they are at their best pointed at Claude — and several reorganised around it.

Install & set up

1. Install

One npm command (Node 18+).

npm install -g @anthropic-ai/claude-code
2. Start it

Run claude in your project and sign in with your Claude account.

cd my-project && claude
3. Plan first

Use plan mode so it proposes an approach and waits for your go-ahead before touching code.

4. Extend it

Connect MCP tools (your database, Paystack, GitHub), add Skills and Hooks, or fan out subagents for big jobs.

From install to your first verified proof

The tool drafts; you stay accountable. Here is the path from a fresh install to a proof you can defend.

1Tell Claude Code the user, the workflow, and the success condition for one small real feature.
2Let it plan, approve, then watch it build across files — reviewing diffs as it goes. The Inspect and Explain steps come naturally because it shows every change.
3Run it, test on mobile, and deploy.
4Log your proof at /proof — the kind of clean, explainable work clients and employers actually trust.
The proof tie: This is the tool that ships proof clients and employers trust. Master it, then prove it at /proof.
