About Claude
Claude is an AI system built by Anthropic, designed around principles of helpfulness, safety, and honesty. It operates as a conversational interface at claude.ai, as an agentic coding tool via Claude Code, and as an API for integration into custom applications.
Use Claude
Foundational resources for working with Claude in daily tasks: writing, research, structured thinking, and iterative problem-solving. Suitable for all skill levels.
Core Features You Should Know
These features turn Claude from a chatbot into a persistent workspace. Understanding them is the difference between casual use and real productivity.
Build with Claude
Resources for integrating Claude into applications and development workflows. Covers the API, Claude Code, tool use, and building structured AI systems.
Design Agents with Claude
Advanced resources for building agentic systems: the Agent SDK, Model Context Protocol, reusable skills, multi-agent orchestration, and cloud deployment.
The augmented LLM: the basic building block with retrieval, tools, and memory
Prompt chaining: sequential steps with programmatic checks between LLM calls
Routing: classify inputs, direct to specialized handlers (Haiku vs. Opus)
Parallelization: run sub-tasks simultaneously and aggregate results

Core Concepts
The principles that connect everything on this page. How Claude processes information, how you structure it, and how the discipline has evolved from writing prompts to designing complete AI environments.
The evolution: prompt engineering focuses on writing one instruction. Context engineering manages the full state across turns, tools, memory, and retrieval.
Finding the right altitude: too specific creates brittleness, too vague lacks guidance. The sweet spot gives strong heuristics without hardcoding logic.

3 ways to work with Claude
Before diving into Cowork or Claude Code, understand which mode fits your task. Chat for thinking. Cowork for working. Code for building.
Cowork
Claude's desktop agent for non-coding work. Runs multi-step tasks in sandboxed folders, coordinates sub-agents, and uses built-in skills for documents, spreadsheets, and presentations. macOS and Windows.

Two new models just landed: Opus 4.6 & Sonnet 4.6
Sonnet 4.6 (Feb 17) is now the default on claude.ai — Opus-level quality at Sonnet price ($3/$15 per 1M tokens). Opus 4.6 (Feb 5) adds Agent Teams, Claude in PowerPoint, and a 1M token context window. Both include adaptive thinking and major improvements in computer use and coding.
Claude Code
Anthropic's agentic coding tool. Runs in terminal, IDE, desktop, and browser. Reads entire codebases, writes and tests code, manages Git, and coordinates sub-agents for complex projects.

Claude Skills
Skills are folders with instructions, scripts, and resources that Claude loads dynamically when relevant. They turn Claude from a general assistant into a specialist for specific tasks. Available across Claude.ai, Claude Code, Cowork, and the API. Open standard since December 2025.
Anatomy of a SKILL.md: metadata (name + description) is loaded at startup, body loaded on demand
Skills bundle additional files: Claude reads them only when the task requires it
Progressive disclosure: metadata → core instructions → nested resources, loaded level by level
How skills activate: system prompt → skill trigger → SKILL.md load → nested file load → task execution
Skills can include executable code: Claude runs scripts without loading them into context
