Integrate Arcjet Guard into the Python Claude Agent SDK — wrap authored @tool with guard_tool, and use guard_hooks for UserPromptSubmit inbound plus PreToolUse on unwrapped built-ins / MCP. Use when asked to add Arcjet to claude-agent-sdk, rate limit those tools, screen inbound prompts, or block prompt injection / PII. This is Python claude-agent-sdk, not the JS adapter and not Claude Managed Agents hosted sessions.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Integrate Arcjet Guard into the Python Claude Agent SDK `arcjet.guard.claude_agent_sdk` wraps the agent's existing Arcjet client. It never talks to the Arcjet API itself. Shared Guard fundamentals (client, rules, labels, decisions, capture, registration) live in [../arcjet/references/guards_python.md](../arcjet/references/guards_python.md). Load that reference for anything that is not Claude Agent SDK-specific. Official `claude-agent-sdk>=0.2.127,<1` only — not the JS `@anthropic-ai/claude-agent-sdk` adapter (`@arcjet/guard/claude-agent-sdk/v0`, docs https://docs.arcjet.com/guards/claude-agent-sdk/), not Vercel AI, not community forks, and not Claude Managed Agents hosted `client.beta.sessions` (`arcjet.guard.claude_managed_agents`). Importing `arcjet.guard.claude_agent_sdk` does not load LangChain, CrewAI, or the JS adapter. The extra is safe (no chromadb). Exports: `guard_tool`, `guard_hooks`, `claude_agent_context`. Authored `@tool` + `create_sdk_mcp_server` for tools you own; `guard_hooks` for inbound `UserPromptSubmit` and unwrapped built-ins / MCP `PreToolUse`. There is no inbound helper and no `guard_can_use_tool`. Three surfaces, one decision rule: …

How to install
mdr add arcjet/skills/integrate-arcjet-guard-claude-agent-sdk-py@sha256:51cd8b58ffa622f4The line at the top of this page pins the label git:20260916.f8959e1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
