|---|---|---|
| Description | Claude Code puts Anthropic's most capable AI models directly into your terminal. Instead of copy-pasting code between your editor and a chat window, you get a coding agent that actually understands your project. The tool reads your entire codebase, tracks file relationships, and makes changes with full context. Need to refactor a module? Fix a bug across five files? Add a feature that touches backend and frontend? Claude Code handles it. It can edit files, run shell commands, search your codebase, and chain multiple operations together without you babysitting every step. It ships as an npm package and installs in about 30 seconds. Once running, it gives you an interactive session where you describe what you want in plain English. The agent figures out which files to read, what changes to make, and which commands to run. It asks for confirmation before executing destructive operations. Claude Code supports several workflows. You can use it interactively for back-and-forth coding sessions. You can pipe input to it for one-shot tasks. It integrates with VS Code and JetBrains through extensions. It also supports custom slash commands and MCP server connections, so you can extend it with external tools and data sources. The tool keeps a conversation history that persists across sessions within a project. It respects your .claudeignore file, similar to .gitignore, so you can exclude files from its context. It also supports CLAUDE.md files for project-specific instructions and conventions. Under the hood, Claude Code runs Claude Sonnet by default. You can switch to Claude Opus for harder tasks. The pricing is consumption-based through the Anthropic API, or you can subscribe to the Max plan ($100/month or $200/month) for higher usage caps. A free tier with rate limits is available through the Anthropic Console. Real-world use cases: generating boilerplate for new services, debugging production issues, writing tests for uncovered code paths, migrating APIs across versions, and documenting existing codebases. Developers report saving 1-3 hours per day on routine coding tasks. | Flex Fitness App is designed to help you build muscle and lose weight quickly and effectively through personalized workouts.
