Claude Code setup: CLI-first features and VS Code caveats

A step-by-step guide shows how to install the Claude Code CLI (curl -fsSL claude.ai | bash), authenticate, and use /init to create a claude.md file that seeds project context. The CLI currently has more capabilities than the VS Code extension (full slash commands, MCP server config, checkpoints), so teams may need a CLI-first workflow even inside the IDE.

[ WHY_IT_MATTERS ]
01.

Using /init and claude.md improves code relevance and consistency across repos.

02.

CLI-first unlocks features like checkpoints and MCP configuration that the VS Code extension lacks today.

[ WHAT_TO_TEST ]
  • terminal

    Measure code accuracy, latency, and token usage with vs. without /init and claude.md across representative backend/data tasks.

  • terminal

    Compare CLI vs VS Code extension for slash command coverage and checkpointing; standardize on the path that meets your needs.

[ BROWNFIELD_PERSPECTIVE ]

Legacy codebase integration strategies...

  • 01.

    Pilot the CLI in an existing repo, add claude.md at the root, and document the Explore→Plan→Confirm→Code→Commit flow.

  • 02.

    Use the IDE terminal to run CLI when the extension falls short, and update onboarding/CI docs to reflect the mixed workflow.

[ GREENFIELD_PERSPECTIVE ]

Fresh architecture paradigms...

  • 01.

    Adopt CLI-first, define a claude.md template and slash-command conventions per repo, and enforce them in project scaffolding.

  • 02.

    Set token limits and checkpoint practices early, and require tests/reviews for all AI-generated changes.
