Claude Code is Anthropic’s agentic coding tool that runs in the terminal (and via IDE integrations). It gives Claude direct, permissioned access to a codebase so it can read, edit, run commands and complete multi-step engineering tasks with the model’s strong reasoning.

## Strengths and weaknesses

- ✓ Terminal-native and scriptable — fits real engineering workflows and CI.
- ✓ Excellent multi-step reasoning over a whole repository.
- ✗ Terminal-first — no full GUI editor for those who want one.
- ✗ Usage-based cost can add up on large, long-running tasks.

## Key features

- **Terminal-native agent** — Runs where developers work — the shell — and composes with scripts and CI.
- **Full-repo context + tools** — Reads the whole codebase and runs real commands (tests, builds) with permission.
- **Strong reasoning** — Built on Claude’s frontier models for multi-step engineering tasks.

## Use cases

- **Autonomous multi-step tasks** — Hand a well-scoped change to Claude Code and let it plan, edit and verify.
- **Scripted / CI automation** — Drive it headless in pipelines for repetitive engineering work.
