Claude Skills by arcjet

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Add Arcjet security protection to HTTP routes, AI agent tool calls, MCP servers, background jobs, and queue workers. Covers rate limiting, bot detection, email validation, prompt injection, sensitive information blocking (including Rampart NER), content moderation, capture/flush, remote Guard policies, typed inputs, and abuse prevention. Works in JavaScript/TypeScript, Python, and Go. HTTP frameworks share this skill. JS Guard adapters that ship on npm are per-adapter reference files loaded f...

Integrate Arcjet Guard into Microsoft Agent Framework for Go (github.com/microsoft/agent-framework-go). Wrap a functool or MCP tool with GuardTool, guard every tool an agent can see and screen inbound text with GuardMiddleware, or guard any Go function with arcjet.GuardAction. Use when asked to add Arcjet to a Go agent built on Microsoft Agent Framework, rate limit its tools, block prompt injection, or fail closed on tool calls. This is the Go framework, not the .NET or Python Microsoft Agent...

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.

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.

Integrate Arcjet Guard into Cloudflare Think — delegate beforeToolCall to guardHooks so a DENY substitutes or blocks the tool, and read a caller-owned id via cloudflareThinkContext. Use when asked to add Arcjet to @cloudflare/think, Cloudflare Agents Think, rate limit those tools, screen inbound messages, or block prompt injection / PII. This is Cloudflare Think, not the Vercel AI SDK and not needsApproval HITL.

Integrate Arcjet Guard into official CrewAI — register process-wide PRE_TOOL_CALL with register_arcjet_hooks, or wrap a standalone BaseTool you call yourself with guard_tool. Use when asked to add Arcjet to CrewAI, LiteAgent, crew-injected tools, rate limit those tools, screen inbound messages before kickoff, or block prompt injection / PII. Official crewai only; not an npm CrewAI port and not LangChain Crew wrappers.

Integrate Arcjet Guard into Python Google ADK — assign guard_tool to LlmAgent(before_tool_callback=), put guard_plugin first on Runner(plugins=) so a deny dict with arcjetDenied skips the tool, and read a caller-owned id via google_adk_context. Use when asked to add Arcjet to google-adk, Google ADK Python, rate limit those tools, screen inbound messages, or block prompt injection / PII. This is Python google-adk 2.x, not JS @google/adk and not @google/genai.

Integrate Arcjet Guard into Python LangChain — wrap a BaseTool you call with guard_tool, put ArcjetMiddleware + ToolPolicy on create_agent, or observe a chain with ArcjetCaptureHandler. Use when asked to add Arcjet to LangChain, create_agent, langchain-core tools, rate limit those tools, screen inbound messages, or block prompt injection / PII. This is Python LangChain, not LangChain JS createAgent and not LangGraph JS.

Integrate Arcjet Guard into Python OpenAI Agents — wrap FunctionTool / function_tool with guard_tool and read a caller-owned session or conversation id via openai_agents_context. Use when asked to add Arcjet to openai-agents, Runner.run, rate limit those tools, screen inbound messages, or block prompt injection / PII. This is Python openai-agents, not the JS @openai/agents adapter.

Integrate Arcjet Guard into Python Strands Agents — wrap authored @tool with guard_tool, and put guard_hooks on Agent(hooks=) for unwrapped / MCP tools via BeforeToolCallEvent.cancel_tool. Use when asked to add Arcjet to strands / strands-agents, rate limit those tools, screen inbound messages, or block prompt injection / PII. This is Python strands, not JS @strands-agents/sdk.
