### Onboard to a new repository

Source: https://support.claude.com/en/articles/14553517-claude-code-common-developer-use-cases

Use this when working in a new repository for the first time to get a structured overview. The `/init` command scans the project and generates a `CLAUDE.md` file.

```markdown
> /init
> give me a tour of this 
codebase — where's the entry point, how is it structured, what should I 
read first
```

### Faster SDK Startup with --bare

Use the `--bare` flag for significantly faster SDK startup by disabling the default search for local CLAUDE.md files, settings, and MCPs. This is recommended for non-interactive usage where these are specified explicitly.

```bash
claude -p "summarize this codebase" \
    --output-format=stream-json \
    --verbose \
    --bare
```
