HTTP forwarding proxy — formal behavioral contracts middleware with zero code change.

This is the flagship. Drop it between any agent harness and any LLM API. Set one env var. Done.

Quickstart

pip install agentassert-typec-proxy
agentassert-proxy proxy start --contract contract.yaml

Then in your agent environment:

export ANTHROPIC_BASE_URL=http://localhost:9000/anthropic
export OPENAI_BASE_URL=http://localhost:9000/openai

Supported Providers

Provider	Route Prefix	Env Var
Anthropic	/anthropic	ANTHROPIC_BASE_URL
OpenAI	/openai	OPENAI_BASE_URL
Gemini	/gemini	GEMINI_BASE_URL
OpenRouter	/openrouter	OPENROUTER_BASE_URL

Endpoints

Method	Path	Description
GET	/health	Health check, returns contract name and Θ
GET	/status	Full status: Θ, JSD, violation count
POST	/admin/reload	Trigger contract hot-reload

Performance

• p99 overhead < 30ms (excluding provider RTT)
• All regex patterns pre-compiled at startup
• Hot-reload via SHA256 file polling (500ms interval)
• Fail-safe: invalid contract → keeps old monitor
