integrate-arcjet-guard-agent-framework-go

integrate-arcjet-guard-agent-framework-go is a skill for Claude Code from arcjet/arcjet-plugin. It costs 119 tokens per session (3,130 once invoked), scanned A, a copy of integrate-arcjet-guard-agent-framework-go, Apache-2.0.

A Go integration for Arcjet Guard, a service that checks whether agent actions or incoming text should be allowed. It connects those checks to Microsoft's Agent Framework for Go, including tools, agents, and ordinary Go functions.

In plain words
What is it for?
Use it to protect Go functions, function or MCP tools, and agent middleware with Arcjet Guard decisions.
Why use it?
It helps apply the same safety check before tools run or text is accepted, without writing separate checks for each integration point.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

integrate-arcjet-guard-agent-framework-go scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 29d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Integrate Arcjet Guard into Microsoft Agent Framework for Go

github.com/arcjet/arcjet-go/agentframework wraps the application's existing arcjet.GuardClient. Shared Guard fundamentals (client, rules, labels, decisions, capture) live in ../arcjet/references/guards_go.md. Load that reference for anything that is not framework-specific.

Three surfaces, one decision rule:

  • Any Go function → arcjet.GuardAction in the root module. No framework dependency. Returns *arcjet.GuardDeniedError or *arcjet.GuardUnavailableError.
  • A tool.FuncTool you can name at wiring time (from functool.New, mcptool.ListTools, or agenttool.New) → agentframework.GuardTool, or GuardTools for a list. The result is still a tool.FuncTool.
  • An agent whose tools the model picks, or user text to screen → agentframework.GuardMiddleware in agent.Config.Middlewares.

This is the Go framework. The .NET and Python Microsoft Agent Framework implementations have no Arcjet adapter. Do not import @arcjet/guard or arcjet.guard here.

Denials are tool results, never errors

The framework replaces a tool error with Error: Function failed. and allows three consecutive rounds of failing tool calls before the fourth ends the run. GuardTool therefore returns arcjet.GuardDenialResult as a successful result. Do not "fix" this by returning an error, and do not set IncludeDetailedErrors to make errors carry the denial.

Fail closed by default

GuardTool, GuardTools, GuardMiddleware, and arcjet.GuardAction deny when policy cannot be evaluated. That is a different outcome from a policy DENY, and the two return different results to the model.

  • Policy could not be evaluated: arcjet.NewGuardUnavailableResult(), reason ERROR, five second retry hint.
  • Policy denied the call, such as an exhausted rate limit or detected prompt injection: arcjet.NewGuardDenialResult(decision), or whatever ToolPolicy.OnDeny returns in its place.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
