agentassert-typec-sdk 0.4.0

AgentAssert Type-C SDK wrapper — wrap(Anthropic(), 'contract.yaml') to enforce behavioral contracts on direct API clients.

agentassert-typec-sdk

One-line wrap. Your Anthropic/OpenAI clients, contract-enforced.

from anthropic import Anthropic
from agentassert_typec_sdk import wrap

client = wrap(Anthropic(), "contract.yaml")
# client.messages.create(...)  ← now contract-enforced
# Raises ContractBreachError on DENY
# Return type is UNCHANGED — same Anthropic response

Supported Clients

• anthropic.Anthropic / anthropic.AsyncAnthropic
• openai.OpenAI / openai.AsyncOpenAI

How It Works

1. wrap() detects client type by class name
2. Intercepts messages.create() / chat.completions.create()
3. Evaluates PreAction before forwarding
4. Raises ContractBreachError on DENY
5. Sends PostAction after response for drift/Θ updates

For Unsupported Clients

Use the proxy instead — no code change, just env vars.

pip install agentassert-typec-proxy
export ANTHROPIC_BASE_URL=http://localhost:9000/anthropic
