Agent Governance Toolkit

Skill by ara.so — AI Agent Skills collection.

Microsoft's Agent Governance Toolkit (AGT) provides production-grade policy enforcement, zero-trust identity, execution sandboxing, and reliability engineering for autonomous AI agents. It addresses the core problem that prompt-level safety is probabilistic, while production systems require deterministic guarantees. AGT intercepts every tool call, message send, and delegation before execution, making policy violations structurally impossible rather than merely unlikely.

由ara.so提供的Skill — AI Agent Skills集合。

Microsoft的**Agent Governance Toolkit（AGT）**为自主AI Agent提供了生产级别的策略执行、零信任身份认证、执行沙箱以及可靠性工程能力。它解决了一个核心问题：提示级别的安全性是概率性的，但生产系统需要确定性的保障。AGT会在执行前拦截每一次工具调用、消息发送和委托操作，从结构上杜绝策略违规的可能性，而非仅仅降低其发生概率。

Core API: Simple Governance Wrapper

核心API：简易治理包装器

The fastest way to add governance is the

govern()

function wrapper:

python

from agentmesh.governance import govern

添加治理功能最快的方式是使用

govern()

函数包装器：

python

from agentmesh.governance import govern

Wrap any tool function

包装任意工具函数

def send_email(to: str, subject: str, body: str): # ... actual email sending logic return {"sent": True, "to": to}

def send_email(to: str, subject: str, body: str): # ... 实际邮件发送逻辑 return {"sent": True, "to": to}

Add governance with YAML policy

通过YAML策略添加治理

safe_send_email = govern(send_email, policy="email_policy.yaml")

Now all calls are checked against policy

现在所有调用都会经过策略检查

try: result = safe_send_email( to="user@example.com", subject="Report", body="Here is the report" ) print(f"Email sent: {result}") except GovernanceDenied as e: print(f"Policy blocked: {e}")


**Policy file** (`email_policy.yaml`):

```yaml
apiVersion: governance.toolkit/v1
name: email-policy
default_action: allow
rules:
  - name: block-external-domains
    condition: "not to.endswith('@mycompany.com')"
    action: deny
    description: "Only internal emails allowed"

  - name: require-approval-for-all
    condition: "to.startswith('exec-')"
    action: require_approval
    approvers: ["security-team"]
    description: "Executive emails need approval"

try: result = safe_send_email( to="user@example.com", subject="Report", body="Here is the report" ) print(f"邮件已发送: {result}") except GovernanceDenied as e: print(f"策略拦截: {e}")


**策略文件** (`email_policy.yaml`):

```yaml
apiVersion: governance.toolkit/v1
name: email-policy
default_action: allow
rules:
  - name: block-external-domains
    condition: "not to.endswith('@mycompany.com')"
    action: deny
    description: "仅允许发送内部邮件"

  - name: require-approval-for-all
    condition: "to.startswith('exec-')"
    action: require_approval
    approvers: ["security-team"]
    description: "发送给高管的邮件需要审批"

Policy Engine: Programmatic Control

策略引擎：程序化控制

For dynamic policies or runtime control:

python

from agent_os.policies import (
    PolicyEvaluator,
    PolicyDocument,
    PolicyRule,
    PolicyCondition,
    PolicyAction,
    PolicyOperator,
    PolicyDefaults
)

针对动态策略或运行时控制：

python

from agent_os.policies import (
    PolicyEvaluator,
    PolicyDocument,
    PolicyRule,
    PolicyCondition,
    PolicyAction,
    PolicyOperator,
    PolicyDefaults
)

Define policy programmatically

程序化定义策略

policy = PolicyDocument( name="tool-safety-policy", version="1.0", defaults=PolicyDefaults(action=PolicyAction.ALLOW), rules=[ PolicyRule( name="block-destructive-operations", condition=PolicyCondition( field="action_type", operator=PolicyOperator.IN, value=["delete", "drop", "truncate", "rm"] ), action=PolicyAction.DENY, priority=100, metadata={"risk_level": "critical"} ), PolicyRule( name="require-approval-for-external-api", condition=PolicyCondition( field="destination", operator=PolicyOperator.REGEX, value=r"^https?://(?!internal.)" ), action=PolicyAction.REQUIRE_APPROVAL, approvers=["security-team"], priority=50 ) ] )

Create evaluator

创建评估器

evaluator = PolicyEvaluator(policies=[policy])

Evaluate actions

评估操作

result = evaluator.evaluate({ "tool_name": "database_query", "action_type": "select", "table": "users" }) if result.allowed: print("Action allowed") else: print(f"Action denied: {result.reason}")

result = evaluator.evaluate({ "tool_name": "database_query", "action_type": "select", "table": "users" }) if result.allowed: print("操作已允许") else: print(f"操作已拒绝: {result.reason}")

Evaluate destructive action

评估破坏性操作

result = evaluator.evaluate({ "tool_name": "database_admin", "action_type": "drop", "table": "users" }) assert not result.allowed print(f"Blocked: {result.matched_rule.name}")

undefined

result = evaluator.evaluate({ "tool_name": "database_admin", "action_type": "drop", "table": "users" }) assert not result.allowed print(f"已拦截: {result.matched_rule.name}")

Agent Identity & Mesh

Agent身份与网格

Zero-trust identity for multi-agent systems:

python

from agent_mesh import AgentMeshClient, AgentIdentity

面向多Agent系统的零信任身份认证：

python

from agent_mesh import AgentMeshClient, AgentIdentity

Create agent with DID identity

创建带有DID身份的Agent

client = AgentMeshClient.create( agent_name="data-analyzer-agent", identity_type="did", # or "spiffe" for SPIFFE IDs policy_paths=["policies/data-access.yaml"] )

client = AgentMeshClient.create( agent_name="data-analyzer-agent", identity_type="did", # 或选择"spiffe"使用SPIFFE ID policy_paths=["policies/data-access.yaml"] )

Get agent's identity

获取Agent身份

identity = client.get_identity() print(f"Agent DID: {identity.did}") print(f"Public Key: {identity.public_key}")

identity = client.get_identity() print(f"Agent DID: {identity.did}") print(f"公钥: {identity.public_key}")

Execute tool with governance + identity attestation

结合治理与身份认证执行工具

result = client.execute_with_governance( tool_name="query_database", parameters={ "query": "SELECT * FROM users WHERE age > 18", "database": "production" }, caller_identity=identity )

if result.allowed: print(f"Query result: {result.output}") else: print(f"Denied: {result.denial_reason}")

undefined

result = client.execute_with_governance( tool_name="query_database", parameters={ "query": "SELECT * FROM users WHERE age > 18", "database": "production" }, caller_identity=identity )

if result.allowed: print(f"查询结果: {result.output}") else: print(f"已拒绝: {result.denial_reason}")

undefined

Execution Sandboxing

执行沙箱

Four privilege rings for defense in depth:

python

from agent_runtime import PrivilegeRing, SandboxedExecutor

用于深度防御的四个权限环：

python

from agent_runtime import PrivilegeRing, SandboxedExecutor

Create sandboxed executor with Ring-3 (untrusted)

创建Ring-3（非信任级）沙箱执行器

executor = SandboxedExecutor( privilege_ring=PrivilegeRing.RING_3, allowed_syscalls=["read", "write", "stat"], network_policy="deny", filesystem_policy="read-only:/data" )

Execute untrusted agent code

执行非信任Agent代码

async def untrusted_tool(): # This code runs in isolated sandbox import os return os.listdir("/data") # Allowed # os.system("rm -rf /") # Would be blocked

result = await executor.execute(untrusted_tool) print(f"Sandbox result: {result}")

async def untrusted_tool(): # 此代码在隔离沙箱中运行 import os return os.listdir("/data") # 允许操作 # os.system("rm -rf /") # 会被拦截

result = await executor.execute(untrusted_tool) print(f"沙箱执行结果: {result}")

Ring-0: Kernel operations (policy changes, identity rotation)

Ring-0: 内核级操作（策略变更、身份轮换）

Ring-1: Privileged agents (admin tools, cross-agent messaging)

Ring-1: 特权Agent（管理工具、跨Agent消息传递）

Ring-2: Standard agents (most business logic)

Ring-2: 标准Agent（多数业务逻辑）

Ring-3: Untrusted agents (external plugins, user-submitted code)

Ring-3: 非信任Agent（外部插件、用户提交代码）

Common Patterns

常见模式

Pattern: Policy-First Development

模式：策略优先开发

python

undefined

python

undefined

1. Write policy FIRST (before agent code)

1. 先编写策略（在Agent代码之前）

policy.yaml

""" rules:

name: allow-safe-tools condition: "tool in ['search', 'calculate']" action: allow
name: deny-all-else condition: "true" action: deny """

""" rules:

name: allow-safe-tools condition: "tool in ['search', 'calculate']" action: allow
name: deny-all-else condition: "true" action: deny """

2. Write agent code against policy

2. 基于策略编写Agent代码

def my_agent_tool(tool: str, **kwargs): # This will be governed pass

def my_agent_tool(tool: str, **kwargs): # 此函数会被治理管控 pass

3. Wrap with governance

3. 用治理包装函数

safe_tool = govern(my_agent_tool, policy="policy.yaml")

4. Test that policy works

4. 测试策略是否生效

try: safe_tool("search", query="test") # Allowed safe_tool("delete_database") # Raises GovernanceDenied except GovernanceDenied: print("Policy working correctly")

undefined

try: safe_tool("search", query="test") # 允许 safe_tool("delete_database") # 抛出GovernanceDenied异常 except GovernanceDenied: print("策略生效")

undefined

Pattern: Tiered Trust Levels

模式：分层信任级别

python

undefined

python

undefined

Different policies for different trust levels

为不同信任级别配置不同策略

untrusted_agent = AgentMeshClient.create( agent_name="user-submitted-plugin", policy_paths=["policies/untrusted.yaml"], # Very restrictive privilege_ring=PrivilegeRing.RING_3 )

standard_agent = AgentMeshClient.create( agent_name="business-logic-agent", policy_paths=["policies/standard.yaml"], # Moderate restrictions privilege_ring=PrivilegeRing.RING_2 )

privileged_agent = AgentMeshClient.create( agent_name="admin-agent", policy_paths=["policies/privileged.yaml"], # Minimal restrictions privilege_ring=PrivilegeRing.RING_1 )

undefined

untrusted_agent = AgentMeshClient.create( agent_name="user-submitted-plugin", policy_paths=["policies/untrusted.yaml"], # 限制严格 privilege_ring=PrivilegeRing.RING_3 )

standard_agent = AgentMeshClient.create( agent_name="business-logic-agent", policy_paths=["policies/standard.yaml"], # 中等限制 privilege_ring=PrivilegeRing.RING_2 )

privileged_agent = AgentMeshClient.create( agent_name="admin-agent", policy_paths=["policies/privileged.yaml"], # 限制极少 privilege_ring=PrivilegeRing.RING_1 )

Layer 1: Policy enforcement

第一层：策略执行

safe_tool = govern(tool, policy="policy.yaml")

Layer 2: Identity verification

第二层：身份验证

result = client.execute_with_governance( tool_name="query_db", parameters=params, caller_identity=agent_identity # Verifies caller )

result = client.execute_with_governance( tool_name="query_db", parameters=params, caller_identity=agent_identity # 验证调用者身份 )

Layer 3: Execution sandboxing

第三层：执行沙箱

executor = SandboxedExecutor(privilege_ring=PrivilegeRing.RING_3) sandboxed_result = await executor.execute(safe_tool)

Layer 4: Audit logging

第四层：审计日志

audit_logger.log(AuditEvent(...))

Layer 5: Kill switch monitoring

第五层：终止开关监控

if kill_switch.is_active(agent_id): raise AgentDisabledError()

undefined

if kill_switch.is_active(agent_id): raise AgentDisabledError()
