Learn how to install Claude Code, open a repository, prompt it effectively, review changes, run tests, and build a safe repeatable workflow. This independent guide focuses on practical workflow, current product positioning, and the questions that matter before you adopt an AI coding tool.
Install and authenticate
Follow the official setup guide. Anthropic currently recommends its native installer and also documents Homebrew, WinGet, Linux package managers, and npm. After installation, authenticate with a supported Claude account, Anthropic Console billing, or an approved enterprise provider.
Start inside the right repository
Open a terminal, change into the project directory, and run claude. Begin with a read-only orientation prompt such as “Explain the architecture, entry points, test commands, and the files involved in authentication.” This gives you a chance to verify its understanding before authorizing edits.
Features, models, limits, ownership, and prices can change. Verify time-sensitive details on the linked official product pages before making a purchase or migration decision.
Write outcome-focused prompts
State the desired behavior, constraints, affected area, and definition of done. A useful request is: “Add server-side validation to the signup endpoint, preserve the current API response shape, add tests for invalid domains, and run the relevant test suite.” Avoid vague prompts that make product decisions implicitly.
Review the plan and diff
Ask for a short plan when the task crosses several files. After implementation, inspect every changed file, review the diff, and request an explanation of surprising decisions. Run the project’s formatter, type checker, tests, and build rather than relying on a verbal claim that the task is complete.
Build a repeatable workflow
Document project commands and conventions in repository instructions. Use separate branches, keep commits focused, and restore a clean state before unrelated work. Over time, reusable commands, hooks, and MCP integrations can reduce repeated context while preserving explicit permissions.
Make the decision with your own workflow
Use a representative repository, clear acceptance criteria, and measurable review outcomes. Foundly helps builders research markets, compare opportunities, and validate what is worth building before committing resources.

What command starts Claude Code?
Run claude from the project directory after installation and authentication.
Should I let Claude Code run every command?
No. Review permissions and commands, especially those that modify infrastructure, data, dependencies, or deployment state.
How do I get better results?
Provide a clear outcome, constraints, relevant context, and a verifiable definition of done.
