1. Production Architecture: Dual-LLM Privilege Separation, Input/Output Classifiers & Sandboxed Tool Execution

from dataclasses import dataclass

@dataclass(frozen=True)
class ToolCallPolicy:
    allowed_tools: frozenset[str]
    max_dollar_amount: int
    require_human_approval: bool

def verify_agent_tool_call(tool_name: str, args: dict, policy: ToolCallPolicy) -> bool:
    if tool_name not in policy.allowed_tools:
        raise PermissionError(f"Tool '{tool_name}' blocked by zero-trust guardrail policy.")
    if args.get("amount_cents", 0) > policy.max_dollar_amount * 100:
        raise PermissionError("Transaction exceeds autonomous agent limit; human approval required.")
    return True

2. Core Architectural Guarantees

• OWASP LLM01 Indirect Prompt Injection Defense: Isolating untrusted retrieved documents and emails from system instruction privileges.
• Deterministic Policy Enforcement: Validating every tool call against strict RBAC and dollar-threshold rules before execution.
• Automated Red-Teaming in CI/CD: Running adversarial jailbreak and exfiltration test suites on every prompt or model update.

3. Topical Category Hubs & Master Directory

• Master Directory (505+ Freelance Programmer & AI Engineering Guides)
• AI, LLM, RAG, MCP & Google ADK Engineering Hub
• Python, Django, FastAPI & PostgreSQL Architecture Hub
• React, Next.js 15 & TypeScript Frontend Performance Hub
