integrate-arcjet-guard-claude-managed-agents-py SKILL.md skillA
integrate-arcjet-guard-claude-managed-agents-py from arcjet/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it. Integrate Arcjet Guard into Python Claude Managed Agents — screen user.message with guard_events before sessions.events.send, and gate custom tools on agent.custom_tool_use with guard_custom_tool. Use when asked to add Arcjet to hosted Claude Managed Agents, anthropic beta sessions, rate limit custom tools, or block prompt injection on hosted sessions. Not Claude Agent SDK local query() / PreToolUse.

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 Python Claude Managed Agents `arcjet.guard.claude_managed_agents` 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 Managed Agents-specific. Official `anthropic>=0.92.0,<2` only — not `claude-agent-sdk`, not `arcjet.guard.claude_agent_sdk`, not the JS `@anthropic-ai/claude-agent-sdk` adapter, and not JS Claude Managed Agents (`@arcjet/guard/claude-managed-agents/v0`, docs https://docs.arcjet.com/guards/claude-managed-agents/). Importing `arcjet.guard.claude_managed_agents` does not load Claude Agent SDK, LangChain, or CrewAI. The extra is safe (no chromadb). This is the hosted Claude Managed Agents harness (`client.beta.sessions`). Anthropic runs the agent loop and the built-in toolset (`bash`, files, web_*). The agent toolset defaults to `always_allow`, so there is **no customer pre-exec** for bash/files — `agent.tool_use` / `agent.tool_result` fire after the built-in already …

How to install
mdr add arcjet/skills/integrate-arcjet-guard-claude-managed-agents-py@git:20261003.d9b5d6dmdr add arcjet/skills/integrate-arcjet-guard-claude-managed-agents-py@sha256:248a23d948435338Pin to a label like 1.0.0, or to a sha256 fingerprint for the exact contents. Either way, the exact version is written to mdr.lock. mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
