Covers agent initialization, configuration, and basic setup patterns. allowed-tools: - Read - Write - Edit - Bash - Grep - Glob --- # Claude Agent SDK - Agent Creation Creating and configuring AI agents using the Claude Agent SDK with TypeScript. ## Core Agent Initialization ### Basic Agent Creation ```typescript import { Agent } from '@anthropic-ai/claude-agent-sdk'; const agent = new Agent({ model: 'claude-3-5-sonnet-20241022', // Latest model systemPrompt: 'You are a helpful assistant specialized in...', settingSources: ['project'], // Load .claude/CLAUDE.md from project allowedTools: ['read_file', 'write_file', 'list_files'], }); ``` ## Configuration Options ### System Prompts ```typescript // Direct system prompt const agent = new Agent({ systemPrompt: 'You are an expert code reviewer...', }); // Load from CLAUDE.md const agent = new Agent({ settingSources: ['project'], // Loads ./.claude/CLAUDE.md }); // User-level memory const agent = new Agent({ settingSources: ['user'], // Loads ~/.claude/CLAUDE.md }); ``` ### Tool Permissions ```typescript // Allow specific tools const agent = new Agent({ allowedTools: [ 'read_file', 'write_file', 'list_files', 'grep', 'bash', ], }); // Block specific tools const agent = new Agent({ disallowedTools: ['bash', 'web_search'], }); // Permission modes const agent = new Agent({ permissionMode: 'strict', // Require explicit approval }); ``` ## Agent Directory Structure ### Required Structure ``` project/ ├── .claude/ │ ├── CLAUDE.md # Project memory │ ├── agents/ │ │ └── specialist.md # Subagent definitions │ ├── skills/ │ │ └── my-skill/ │ │ └── SKILL.md # Skill definitions └── src/ └── index.ts # Your code ``` ## Authentication ### Environment Variables ```bash # Anthropic API (primary) export ANTHROPIC_API_KEY="sk-ant-..." # Alternative providers export AWS_ACCESS_KEY_ID="..." export AWS_SECRET_ACCESS_KEY="..." export AWS_REGION="us-east-1" # Google Vertex AI export GOOGLE_APPLICATION_CREDENTIALS="/path/to/credentials.json" # Azure export AZURE_OPENAI_API_KEY="..." export AZURE_OPENAI_ENDPOINT="..." ``` ### SDK Configuration ```typescript // Anthropic direct const agent = new Agent({ apiKey: process.env.ANTHROPIC_API_KEY, }); // Amazon Bedrock const agent = new Agent({ provider: 'bedrock', model: 'anthropic.claude-3-5-sonnet-20241022-v2:0', }); ``` ## Best Practices ### Always Specify Model ```typescript // Good const agent = new Agent({ model: 'claude-3-5-sonnet-20241022', }); // Avoid: relying on default model const agent = new Agent({}); ``` ### Use Explicit Setting Sources ```typescript // Good const agent = new Agent({ settingSources: ['project'], }); // Avoid: unclear memory source const agent = new Agent({ systemPrompt: '...', }); ``` ### Separate Project and User Memory ```typescript // Project-specific context const projectAgent = new Agent({ settingSources: ['project'], }); // User preferences const userAgent = new Agent({ settingSources: ['user'], }); ``` ## Anti-Patterns ### Don't Hardcode API Keys ```typescript // Bad const agent = new Agent({ apiKey: 'sk-ant-hardcoded-key', }); // Good const agent = new Agent({ apiKey: process.env.ANTHROPIC_API_KEY, }); ``` ### Don't Mix Conflicting Permissions ```typescript // Bad: contradictory permissions const agent = new Agent({ allowedTools: ['read_file', 'write_file'], disallowedTools: ['read_file'], // Conflict! }); // Good: clear permissions const agent = new Agent({ allowedTools: ['read_file'], }); ``` ## Related Skills - **tool-integration**: Working with tools and MCP servers - **context-management**: Managing agent context and memory --- Source attribution: TheBushidoCollective Original project: https://github.com/TheBushidoCollective/han/blob/19caa51d5fd144ef6b2764f2332f4c856aa5d1af/plugins/specialized/claude-agent-sdk/skills/agent-creation/SKILL.md License: Apache-2.0 License information: https://www.apache.org/licenses/LICENSE-2.0 Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice # Functional Source License, Version 1.1, ALv2 Future License ## Abbreviation FSL-1.1-ALv2 ## Notice Copyright 2025 The Bushido Collective ## Terms and Conditions ### Licensor ("We") The party offering the Software under these Terms and Conditions. ### The Software The "Software" is each version of the software that we make available under these Terms and Conditions, as indicated by our inclusion of these Terms and Conditions with the Software. ### License Grant Subject to your compliance with this License Grant and the Patents, Redistribution and Trademark clauses below, we hereby grant you the right to use, copy, modify, create derivative works, publicly perform, publicly display and redistribute the Software for any Permitted Purpose identified below. ### Permitted Purpose A Permitted Purpose is any purpose other than a Competing Use.
