Anthropic Agent Tools
Anthropic's official tool use, computer use, and agent patterns. Reference implementation for Claude-based agents.
Viable option — review the tradeoffs
You need a reliable reference for building Claude-powered agents with tool use, computer use, and agent patterns without reinventing core patterns.
Excellent Claude-native performance with dynamic tool discovery and execution; quirks include 24-hour file retention for generated docs and nested response parsing.
You want agents that generate real files like Excel, PowerPoint, or PDFs without custom code interpreters.
Claude autonomously creates professional documents; files expire after 24 hours, custom Skills via SKILL.md upload extend capabilities.
Skills files expire after 24 hours
Generated documents via Skills API live in Anthropic's Files API for only 24 hours; must download immediately using provided helpers.
Anthropic API key + beta headers
Advanced features like Skills require specific beta flags (skills-2025-10-02, code-execution-2025-08-25) and code_execution tool.
Nested file ID extraction
Skills responses bury file IDs 4+ levels deep; use AnthropicSkillsResponseHelper's recursive search or manually parse to avoid missing generated files.
