zebbern/claude-code-guide: A Reference Repository for Claude Code, Not a Tool You Install

What Problem a Documentation Repository Solves

Claude Code ships as a CLI, but the surface around it is wide: slash commands, environment variables, configuration files, MCP servers, sub agents, skills, hooks, sandbox mode, worktree isolation and a plugin system all appear in this repository's content map. A new user has to discover which of those exist before deciding which to configure. This repository exists to answer that discovery question in one place. Its stated audience runs from beginner to power user, and the structure reflects that: Getting Started, Configuration & Environment, Commands & Usage, Interface & Input, Advanced Features, Security & Permissions, Automation & Integration, Help & Troubleshooting, and Third-Party Integrations. The repository is written in Python according to its primary language field, though nothing in the supplied material describes a Python package, module or CLI entry point. That mismatch matters. If you arrived expecting an installable library, the README does not support that expectation; the content is prose, tables and command examples.

How the Guide Is Organised and What That Tells You

The README opens with a status table that maps each section to an external resource: official Claude Code docs for Getting Started, a Discord integration repository for Configuration, a skills repository for Commands, and so on. Each row carries a checkmark status, which reads as a claim that the section is written rather than as a version stamp. There is also a collapsed full content map listing roughly forty topics, from Thinking Mode and Effort Levels through to Remote Control, Managed Settings and Model Updates. That breadth is the repository's main asset and its main risk. Breadth means a reader can find the name of a feature quickly. Risk means a forty-topic map maintained by hand will drift from the product it describes, and the README acknowledges this directly in its opening note: commands and provider model mappings change quickly, and the linked official references remain authoritative. Treat the content map as an index, not as a specification.

Getting Claude Code Running: The Commands the Guide Actually Shows

The installation path the README recommends is the native installer, which it notes does not require Node.js. For macOS, Linux or WSL the documented command is:

curl -fsSL https://claude.ai/install.sh | bash

The README also begins a Windows PowerShell variant, but the supplied text is truncated mid-word at "Windows Powe", so the Windows command cannot be reproduced here and should be read from the repository itself. Once installed, the guide's Quick Start tip is to run claude in a project directory to start the interface. Configuration is described as happening through a /config command run inside Claude Code; the README gives the example of choosing a notification channel such as Terminal bell to enable completion alerts. Beyond that, the guide points to two further areas by name: Environment Variables and Configuration Files, both listed under the Configuration & Environment heading. The exact variable names and file paths are not present in the supplied excerpt, so anyone planning to script a setup should open those sections directly rather than infer them.

Where the Guide Is Thin, and Where It Is Honest About Being Thin

The strongest signal in this README is the disclaimer near the top. Saying that commands and provider model mappings change quickly, and that the linked official references remain authoritative, is an unusual thing for a community guide to state plainly. It sets the correct expectation: this is a secondary source. The weakness follows from the same fact. A repository that covers Advanced Features, Security & Permissions, Automation & Integration and Third-Party Integrations in one document cannot go deep on any of them, and the supplied material gives no indication of per-section depth, version coverage, or when each section was last checked against the CLI. There are no releases retrieved for this repository, so there is no changelog to consult for what changed between revisions. The last push date is 2026-09-10, which tells you the repository is active but not which sections were touched. If you need behaviour guarantees for hooks or sandbox mode, this is the wrong source; the official documentation is.

Alternatives: Reading the Official Docs Directly

The obvious alternative is to skip the guide and read code.claude.com/docs/en/overview, which this repository links as its reference and contribution target. The difference in approach is not quality, it is role. The official documentation is the definition of behaviour: it is where a command's flags, an environment variable's accepted values, or a permission model's rules are decided, and it is updated by the people who ship the CLI. This guide is an aggregation layer: it collects topics, links out to sibling repositories for specific concerns (a Discord MCP agent, a skills collection, Mermaid templates), and presents them in a single reading order. If your question is "does this flag exist and what does it do", the official docs answer it. If your question is "what are the areas of Claude Code I have not looked at yet", this repository answers it faster because the content map is one screen long. The two are complements, and the README treats them that way.

Licence, Maintenance and the Cost of Following a Moving Target

The repository is MIT licensed, which permits reuse and modification with the usual requirement to retain the copyright and permission notice; that is a description of the licence text, not legal advice, and anyone redistributing substantial portions should read the LICENSE file in the repository. Maintenance cost is the real consideration. Because the subject is a CLI whose commands and provider mappings change, the repository carries an ongoing editorial burden that a normal library does not: every upstream change is a potential inaccuracy in a document with no test suite to catch it. The absence of releases means consumers have no versioned artifact to pin against. In practice that means you consume this repository at a point in time. If you copy a command out of it into a script or a CI job, the thing you should pin is your claude CLI version, not the guide.

Who This Repository Is For

Use it if you are starting with Claude Code and want a structured index of what the tool exposes, or if you are evaluating whether features like sub agents, skills or MCP integration are worth the setup effort and want a single page that names them alongside pointers to deeper material. Use it as a starting point for the sibling repositories it links, such as the skills and MCP projects listed in its resource table. Do not use it as the source of truth for a production automation pipeline, and do not expect it to document a specific CLI version's behaviour precisely. The honest summary is that this is a well-organised front door with the caveat printed on it, and the caveat is the most trustworthy sentence in the README.

Editorial conclusion

Adopt this repository as a navigation layer if you are new to Claude Code and want one page that lists slash commands, environment variables, MCP, sub agents, skills and hooks in a single structure. Do not adopt it as an installation target: there is no package to install here, and the README itself states that commands and provider model mappings change quickly and that the linked official references remain authoritative. Before relying on any section, verify it against the official Claude Code documentation at code.claude.com, and check the specific command or environment variable name you intend to use against your installed version of the claude CLI.
