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.
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 Cloudflare Think `@arcjet/guard/cloudflare-think/v0` 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_javascript.md](../arcjet/references/guards_javascript.md). Load that reference for anything that is not Think-specific. Official `@cloudflare/think` `>=0.3.0 <1` only — that is the first release whose `beforeToolCall` returns a functional `ToolCallDecision` (`allow` / `block` / `substitute`) and wraps every server-side tool's `execute` so the hook runs first. There is no `/v1` until Think ships 1.x. This is **not** the Vercel AI SDK (`ai` / `@arcjet/guard/vercel-ai/v7`). Think owns `streamText` internally; do not also wrap its tools with the AI SDK mix-in. Not TanStack Start HTTP `protect()`. Not Cloudflare Workers HTTP `protect()` (`@arcjet/node` / request-based). Exports: `guardHooks`, `cloudflareThinkContext`. There is **no `guardTool`** and no `guardThink` mixin. Skip is the `beforeToolCall` return, not throw-from-execute. There is no `guardInbound` and no `guardApproval`. No unversioned …

How to install
mdr add arcjet/skills/integrate-arcjet-guard-cloudflare-think@sha256:bdf74ae951484e99The line at the top of this page pins the label git:20260922.4ae5d84, 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.
