Claude Code is a command-line tool that lets developers work with Claude directly from their terminal or command prompt. Think of it as having an AI coding assistant that lives right in your development environment. Here's what makes it useful in simple terms: **What it does:** - You can ask Claude to write code, fix bugs, or explain programming concepts without leaving your terminal - It can read and work with files in your project directory - You can delegate entire coding tasks to Claude and it will work through them step-by-step **Why developers like it:** - No need to copy-paste code back and forth between a web browser and your code editor - Claude can see your actual project files and understand the context of what you're working on - It fits naturally into existing development workflows - You can automate repetitive coding tasks **Example use cases:** - "Claude, add error handling to this function" - "Write unit tests for my new feature" - "Help me refactor this messy code" - "Explain what this legacy code does" It's essentially like having a very pair programming partner who can jump in and help with coding tasks whenever you need it. --- ### Claude Opus 4.6: The Latest Powerhouse **Claude Opus 4.6** is the most capable model in the Claude family (as of February 2026), offering advanced reasoning and coding capabilities. #### Key Specifications | Feature | Specification | |---------|--------------| | **Model ID** | `claude-opus-4-6` | | **Context Window** | 200K tokens (1M beta via API) | | **Max Output** | 128K tokens | | **Availability** | Pro, Max, and API plans | | **Fast Mode** | ✅ Yes (2.5x faster, 6x pricing) | #### Advanced Capabilities **1. Extended Context Window** - Standard: 200K tokens (available to all Pro/Max subscribers) - Beta: 1M tokens (API only, not in subscriptions at launch) - Best for: Analyzing entire large codebases, extensive documentation **2. Adaptive Thinking** - Dynamic reasoning based on task complexity - Automatically scales computational effort - Better problem-solving for complex coding challenges **3.

Top Performance** - Leading scores on Terminal-Bench 2.0 - Superior code generation and debugging - Enhanced context understanding #### When to Use Opus 4.6 **✅ Best For:** - Complex architectural decisions - Large-scale refactoring - Debugging intricate issues - Multi-file analysis - Production-critical code **💡 Consider Sonnet 4.5 or Haiku 4.5 for:** - Simple code changes - Documentation updates - Quick questions - Budget-conscious projects #### Pricing & Access **Subscription Plans:** - Pro ($20/mo): Full access to Opus 4.6 - Max 5x ($100/mo): 5x usage capacity - Max 20x ($200/mo): 20x usage capacity **API Pricing:** - Standard: $5 input / $25 output per MTok - Fast Mode: $30 input / $150 output per MTok (6x) --- ### Claude Code Setup [![Anthropic](Images/Anthropic.png)](https://www.anthropic.com) [![Claude Installation](Images/claude-installation.png)](https://docs.anthropic.com/en/docs/claude-code/overview) --- ### Prompt Engineering Deep Dive > **📖 Claude Initialization** > Run the `/init` command to automatically generate a `CLAUDE.md` file. > Your `CLAUDE.md` files become part of Claude's prompts, so they should be refined like any frequently used prompt. A common mistake is adding extensive content without iterating on its effectiveness. Take time to experiment and determine what produces the best instruction following from the model. #### 1. Explore → Plan → Code → Commit > Versatile workflow for complex problems. - **Explore:** Read relevant files/images/URLs; use subagents for verification. Do **not code yet**. - **Plan:** Ask Claude to make a plan. Use `"think"`, `"think hard"`, `"think harder"`, or `"ultrathink"` to increase computation time. Optionally save plan for future reference. - **Code:** Implement the solution; verify reasonableness as you go. - **Commit:** Commit results, create pull requests, update READMEs/changelogs. - Claude has two default modes: `Plan Mode` and `Accept Edits Mode`. You can toggle between them using the `Shift + Tab` keys. - ![Plan Mode](Images/plan-mode.png) - ![Accept Edit Mode](Images/accept-edit-mode.png) > **💡 Pro Tip:** Research & planning first significantly improves performance for complex tasks. --- #### 2. Test-Driven Workflow (Write Tests → Code → Commit) > Ideal for changes verifiable with unit/integration tests. - **Write Tests:** Create tests based on expected inputs/outputs; mark as TDD. - **Run & Fail Tests:** Confirm they fail; no implementation yet. - **Commit Tests:** Commit once satisfied. - **Write Code:** Implement code to pass tests; iterate with verification via subagents. - **Commit Code:** Final commit after all tests pass. > 🔹 Clear targets (tests, mocks) improve iteration efficiency. --- #### 3. Visual Iteration (Code → Screenshot → Iterate → Commit) - Provide screenshots or visual mocks. - Implement code, take screenshots, iterate until outputs match mock. - Commit once satisfied. > 🔹 Iteration significantly improves output quality (2-3 rounds usually enough). --- ### Claude Commands #### Built-in slash commands | Command | Purpose | | ------------------------- | -------------------------------------------------------------------------------------------------------- | | `/add-dir` | Add additional working directories | | `/agents` | Manage custom AI subagents for specialized tasks | | `/auth login` | Authenticate with your Anthropic account (new Feb 2026) | | `/auth status` | Check authentication status (new Feb 2026) | | `/auth logout` | Sign out from your account (new Feb 2026) | | `/bug` | Report bugs (sends conversation to Anthropic) | | `/clear` | Clear conversation history | | `/compact [instructions]` | Compact conversation with optional focus instructions | | `/config` | View/modify configuration | | `/cost` | Show token usage statistics | | `/debug` | Troubleshoot current session and configuration (new Feb 2026) | | `/doctor` | Checks the health of your Claude Code installation | | `/fast` | Toggle Fast Mode for 2.5x faster Opus 4.6 responses (6x pricing) (new Feb 2026) | | `/help` | Get usage help | | `/hooks` | Interactive menu for hook configuration (new Feb 2026) | | `/init` | Initialize project with CLAUDE.md guide | | `/login` | Switch Anthropic accounts (use `/auth login` instead) | | `/logout` | Sign out from your Anthropic account (use `/auth logout` instead) | | `/mcp` | Manage MCP server connections and OAuth authentication | | `/memory` | Edit CLAUDE.md memory files | | `/model` | Select or change the AI model (Opus 4.6, Sonnet 4.5, Haiku 4.5) | | `/permissions` | View or update [permissions](https://docs.anthropic.com/en/docs/claude-code/iam#configuring-permissions) | | `/pr_comments` | View pull request comments | | `/rename` | Auto-generate descriptive session names (new Feb 2026) | | `/review` | Request code review | | `/status` | View account and system statuses | | `/teleport` | Send current session to claude.ai/code for web access (new Feb 2026) | | `/terminal-setup` | Install Shift+Enter key binding for newlines (built-in since 2026, zero setup needed) | | `/vim` | Enter vim mode for alternating insert and command modes | #### Custom slash commands > **📖 Note:** Custom slash commands allow you to define frequently-used prompts as Markdown files that Claude Code can execute. Commands are organized by scope (project-specific or personal) and support namespacing through directory structures. ```bash mkdir -p .claude/commands echo "Analyze this code for performance issues and suggest optimizations:" > .claude/commands/optimize.md ``` **Example** - Create new file named `pull-request.md` in `.claude/commands` - Add the following info to file ```markdown # Create Pull Request Command Create a new branch, commit changes, and submit a pull request. ## Behavior - Creates a new branch based on current changes - Formats modified files using Biome - Analyzes changes and automatically splits into logical commits when appropriate - Each commit focuses on a single logical change or feature - Creates descriptive commit messages for each logical unit - Pushes branch to remote - Creates pull request with proper summary and test plan ## Guidelines for Automatic Commit Splitting - Split commits by featu --- Source: [Claudary](https://claudary.paisolsolutions.com/skills/readme-120) · https://claudary.paisolsolutions.com
