Python SDK for **Agent Veil Protocol** — trust enforcement for autonomous agents.

**PyPI**: [agentveil](https://pypi.org/project/agentveil/) | **API**: [agentveil.dev](https://agentveil.dev) | **Network**: [Live Network](https://agentveil.dev/live)

> [Why agent trust infrastructure matters](docs/SECURITY_CONTEXT.md) — verified CVEs, market data, and the structural problem AVP addresses.

> **[Open-source contribution merged into Microsoft Agent Governance Toolkit](https://github.com/microsoft/agent-governance-toolkit/pull/1010)** — AVPProvider added as a TrustProvider implementation (PR #1010, merged upstream).

  AVP SDK Demo — trust check, action, signal change, alert, offline proof

> **Full end-to-end walkthrough:** [`examples/proof_pack/`](examples/proof_pack/) — annotated example of the complete arc: trust check → delegation → signal change → alert → offline-verifiable proof. Requires a local AVP backend.

```python
from agentveil import AVPAgent

agent = AVPAgent.load("https://agentveil.dev", "my-agent")

# Should I trust this agent with my task?
decision = agent.can_trust("did:key:z6Mk...", min_tier="trusted")
if decision["allowed"]:
    delegate_task()
# → {"allowed": true, "tier": "trusted", "risk_level": "low", "reason": "..."}
```

---

## Install

```bash
pip install agentveil
```

## Quick Start

### Trust decision — one call

```python
from agentveil import AVPAgent

agent = AVPAgent.load("https://agentveil.dev", "my-agent")
decision = agent.can_trust("did:key:z6Mk...", min_tier="trusted")
print(decision["allowed"], decision["reason"])
```

### Auto-track with decorator

```python
from agentveil import avp_tracked

@avp_tracked("https://agentveil.dev", name="reviewer", to_did="did:key:z6Mk...")
def review_code(pr_url: str) -> str:
    return analysis

# Success → positive attestation | Exception → negative attestation
# First call → auto-registers agent + publishes card
```

### Try without a server

```python
agent = AVPAgent.create(mock=True, name="test_agent")
agent.register(display_name="Test Agent")
rep = agent.get_reputation()
print(rep)  # Works offline — real crypto, mocked HTTP
```

### Verify trust offline — no SDK required

```bash
# Get a W3C Verifiable Credential (VC v2.0)
curl https://agentveil.dev/v1/reputation/{agent_did}/credential?format=w3c
```

The response is a standard W3C VC with a `DataIntegrityProof` (`eddsa-jcs-2022`). Verify it with any VC library — Veramo, SpruceID, Digital Bazaar, or your own Ed25519 implementation. No AVP SDK needed.

```python
# Or verify with the SDK:
cred = agent.get_reputation_credential(format="w3c")
assert AVPAgent.verify_w3c_credential(cred)  # offline, no API call
```

---

## Features

- **Trust Check** — `can_trust()` — one-call advisory trust decision: score + tier + risk + explanation
- **W3C VC v2.0 Credentials** — Trust credentials are W3C Verifiable Credentials compliant (`eddsa-jcs-2022` Data Integrity proof). Verify offline with any standard VC library, no AVP SDK required
- **One-Line Decorator** — `@avp_tracked()` — auto-register, auto-attest, auto-protect
- **DID Identity** — W3C `did:key` (Ed25519). Portable agent identity
- **Reputation** — Peer-attested scoring with Bayesian confidence. Sybil-resistant
- **Attestations** — Signed peer-to-peer ratings. Negative ratings require SHA-256 evidence. Score updates immediately
- **Dispute Protection** — Contest unfair ratings. Auto-assigned arbitrator from verified pool
- **Agent Discovery** — Publish capabilities, find agents by skill and reputation
- **Webhook Alerts** — Push notifications on score drops ([setup guide](docs/WEBHOOKS.md))
- **Sybil Resistance** — Multi-layer graph analysis blocks fake agent rings
- **Trust Gate** — Reputation-based rate limiting (newcomer → basic → trusted → elite)

## Batch Attestations

Submit up to 50 attestations in a single request. Each is validated independently — partial success is possible.

```python
results = agent.attest_batch([
    {"to_did": "did:key:z6MkAgent1...", "outcome": "positive", "weight": 0.9, "context": "code_review"},
    {"to_did": "did:key:z6MkAgent2...", "outcome": "negative", "weight": 0.7, "evidence_hash": "sha256hex..."},
    {"to_did": "did:key:z6MkAgent3...", "outcome": "positive"},
])
print(results["succeeded"], results["failed"])  # 3, 0
```

Each attestation is individually signed with Ed25519. Optional fields: `context`, `evidence_hash`, `is_private`, `interaction_id`.

---

## Security

- Ed25519 signature authentication with nonce anti-replay
- Input validation — injection detection, PII scanning
- Agent suspension — compromised agents instantly blocked
- Audit trail — SHA-256 hash-chained log, anchored to IPFS
