Claude Code

What it is

Claude Code is a terminal-based agent that reads, writes, and runs code with Claude under the hood. Best fit for engineers who want autonomy in the same tools they already use.

Notes from using it

The single biggest lever inside Claude Code is your CLAUDE.md. Teams that drop a one-page CLAUDE.md into the repo root — covering stack, conventions, anti-patterns, and common workflows — get dramatically better results than teams that don't. It's the kind of artifact that should grow weekly for the first month and then stabilize.

The second lever is hooks. Pre-commit lint runs, post-edit type checks, and Stop hooks that fire your test suite when work completes are the difference between Claude Code as a copilot and Claude Code as a real autonomous worker. Most teams don't set them up; the teams that do report meaningfully better PR cycle times.

Where it falls down: long-running sessions without checkpoints. Open-ended "build this whole feature" prompts produce decent first attempts but drift if you don't intervene. The pattern that works is small, well-scoped tickets — same pattern that works with junior engineers.

Where it shines

• Lives in the terminal — composes with any toolchain.
• Strong long-context performance on real codebases.

Where it falls down

• CLI-only — no GUI handholding.
• Best results require disciplined prompts and CLAUDE.md setup.

If you're trying to put AI behind any of these functions, Claude Code is worth a look:

• AI for Code Review — PR review, refactor suggestions, test generation, on-call triage.
