Deterministic Sub-50µs Pre-Flight Invariant Gating for UserProxyAgent Code Execution

Problem Statement

When running autonomous code generation with AutoGen, UserProxyAgent and LocalCommandLineCodeExecutor execute generated code blocks directly on the host machine or container.

Current approaches to mitigate dangerous executions either:

1. Wrap execution in heavy virtualization/Docker containers (high resource overhead, cold start latency).
2. Use remote LLM evaluation proxies (adding 1,200ms to 2,500ms latency per code step).

Proposed Solution: Zero-Latency In-Memory AST Gating

We have built btp-guard (Bartholomew Trust Protocol), an open-source, deterministic compiler-level AST invariant gate that inspects proposed Python, Bash, and SQL code blocks directly in memory in under 50 microseconds before dispatch.

Drop-In AutoGen Integration Example

It plugs directly into AutoGen's custom code execution pipeline:

from autogen.coding import LocalCommandLineCodeExecutor
from btp_guard import guard, SecurityVetoException

class SecureCodeExecutor(LocalCommandLineCodeExecutor):
    def execute_code_blocks(self, code_blocks):
        for block in code_blocks:
            # Sub-50 microsecond in-memory AST and credential leak verification
            is_safe, reason = guard.evaluate(block.language, block.code)
            if not is_safe:
                return 1, f"[BTP Security Veto] Execution aborted: {reason}", None
                
        return super().execute_code_blocks(code_blocks)

Key Technical Properties:

• Execution Overhead: <50 microseconds (over 30,000x faster than cloud moderation proxies).
• Attack Coverage: Catastrophic filesystem wipes (rm -rf), DDL SQL purges (DROP TABLE), fork bombs, dynamic Python introspection (__subclasses__), and high-entropy secret leaks.
• Availability: Published on PyPI (pip install btp-guard) and npm (npm install btp-guard).
• Attestation: RFC 8785 canonical JSON Ed25519 cryptographic receipts for audit logging.

Would the AutoGen maintainers be interested in a cookbook example or extension recipe demonstrating pre-flight in-memory invariant gating for secure agent code execution?
