Claude Code
Claude Code is an AI programming assistance tool developed by Anthropic, built on the Claude large language model. It assists developers with code generation, code completion, error debugging, code explanation, and refactoring across multiple programming languages. The tool can be integrated into mainstream development environments and supports natural language interaction to improve programming efficiency, targeting both individual developers and professional software engineers.
Core Facts
A Skill is a modular encapsulation that packages specialized capabilities, domain knowledge, and operational norms into reusable units, enabling Agents to invoke them automatically at the appropriate moment.
The core carrier of Claude Code's Skills is the CLAUDE.md file, placed in the project root directory or a specific directory.
Claude Code is an AI programming assistant launched by Anthropic.
Timeline (last 90 days)
In herdr, the main Claude Code session can automatically hand mechanical work to Codex based on routing rules in CLAUDE.md, open a Codex pane, wait for its status without polling, and stop to ask the user when Codex hits an approval prompt.
In herdr, fan-out is a Claude Code skill that can create multiple git worktrees for one prompt, launch multiple agents, prompt them in parallel, have each run tests, and finally generate a comparison table, and nothing is merged without the user's approval.
herdr does not wrap coding agents, it only manages their terminals, and supports many agents such as Claude Code, Codex, Gemini, Cursor, and OpenCode.
When version number information (such as 2.1.104) appears in the terminal, it means Claude Code has been installed.
If you need to switch between different Node versions across multiple projects in the future, you can consider using a version management tool like nvm-windows; if it is only used to run Claude Code, simply installing a newer LTS or Current version is enough.
For users in China, a common practice is to configure a proxy or use a third-party gateway compatible with the Anthropic API, and point to the alternative endpoint via environment variables such as ANTHROPIC_BASE_URL.
When running claude for the first time after installation, Claude Code guides the user through login authentication, usually in two ways: using an Anthropic account with browser OAuth authorization, or configuring the ANTHROPIC_API_KEY environment variable.
Installing Claude Code does not require administrator privileges; it can be executed with ordinary privileges.
After installing Claude Code, claude.exe is placed in the .local/bin directory of the user directory; this is the behavior of Claude Code's own installation script, not npm's default rule.
After installing Claude Code, it cannot be used directly yet; configuration steps such as authentication and environment variables are also required.
