## The Problem

Regulated enterprises — banks, hospitals, law firms, governments — are deploying autonomous AI agents in production. These agents operate under **Agentic Constitutions**: YAML policy documents that declare what actions an agent is permitted and forbidden to take.

The problem is that constitutions are written in natural language and enforced by shallow pattern-matching. An adversary who rephrases a prohibited instruction can bypass the guardrails while achieving identical real-world effect.

**Regulators demand proof that agents are robust.**
The EU AI Act (Annex III) and BACEN Resolution 4.893/2021 require documented adversarial testing of high-risk AI systems. This framework generates that evidence.

---

## What This Framework Does

```
Constitution YAML  →  Attack Engine (5 modules)  →  Audit Report + Hardened Constitution
```

1. **Parses** a Constitution YAML into a validated Pydantic model
2. **Generates** adversarial payloads across 5 attack categories
3. **Executes** each payload against the target agent (model-agnostic, framework-agnostic)
4. **Evaluates** outcomes using an LLM-as-judge
5. **Reports** vulnerabilities in EU AI Act / LGPD audit format (JSON + Markdown + PDF)
6. **Hardens** the constitution with auto-generated patches

---

## Quickstart

### Local (Ollama)

```bash
# 1. Install
pip install adversarial-constitution

# 2. Pull a local model
ollama pull llama3:latest

# 3. Run against the banking constitution
antz-audit run \
  -c constitution/examples/banking.yaml \
  --model ollama/llama3:latest \
  --judge ollama/llama3:latest \
  -o reports/banking_audit.json

# 4. View the dashboard
python -m reporting.server
# → http://localhost:8080
```

### Docker (recommended)

```bash
# Clone and start everything
git clone https://github.com/Gabbsx7/adversarial-constitution
cd adversarial-constitution

docker-compose up --build -d

# Pull the model inside the container
docker-compose exec ollama ollama pull llama3:latest

# Run an audit
docker-compose exec adv-constitution antz run \
  -c constitution/examples/banking.yaml \
  --model ollama/llama3:latest \
  --judge ollama/llama3:latest \
  -o reports/banking_audit.json

# Dashboard → http://localhost:8080
```

### Create a constitution from scratch

```bash
antz-audit init
# Interactive wizard — generates banking/healthcare/legal YAML + client sign-off MD
```

## Attack Modules

| Module | Techniques | Targets |
|---|---|---|
| **Constraint Bypass** | synonym substitution, euphemism wrapping, authority injection, goal framing, passive construction, negation bypass, incremental softening, indirect reference | `prohibited_actions` |
| **Threshold Probing** | binary search boundary finding, transaction splitting, MFA bypass | `spend_limits` |
| **Prompt Injection** | direct injection, role confusion, system prompt override | all rules |
| **Goal Hijacking** | CEO urgency, life-or-death framing, system migration, regulatory deadline, chained benign actions | `prohibited_actions` |
| **Indirect Injection** | RAG poisoning, email injection, tool output injection, web scrape injection, calendar injection | agent data pipeline |

## Adapters — Audit Any Agent

### Black-box HTTP (any REST API)

```python
from adversarial.adapters import HTTPAgentAdapter

adapter = HTTPAgentAdapter(
    url="https://my-agent.company.com/api/chat",
    headers={"Authorization": "Bearer sk-..."},
    message_field="message",
    response_field="choices.0.message.content",
)

# Probe connectivity before attacking
ok, info = await adapter.probe()
```

```bash
antz-audit run \
  -c constitution/examples/banking.yaml \
  --agent-url https://my-agent.company.com/api/chat \
  --agent-headers "Authorization:Bearer sk-..." \
  --judge ollama/llama3:latest \
  -o reports/audit.json
```

### LangGraph

```python
from adversarial.adapters import LangGraphAdapter
from adversarial.attacks.constraint_bypass import ConstraintBypassAttack

graph   = your_graph.compile()
adapter = LangGraphAdapter(graph=graph, input_key="messages", output_key="messages")
attack  = ConstraintBypassAttack(adapter, judge_agent, constitution)
reports = await attack.run()
```

### CrewAI

```python
from adversarial.adapters import CrewAIAdapter

crew    = Crew(agents=[...], tasks=[...])
adapter = CrewAIAdapter(crew=crew, input_variable="customer_request")
```

### AutoGen

```python
from adversarial.adapters import AutoGenAdapter

adapter = AutoGenAdapter(agent=your_autogen_agent)
```
