# Protocol specifications

> QWED formal specifications for interoperability. Overview of QWED-SPEC, QWED-Attestation, and QWED-Agent protocols for deterministic AI verification systems.

QWED is defined by formal specifications that enable interoperability.

## Core specifications

| Specification                          | Version | Description              |
| -------------------------------------- | ------- | ------------------------ |
| [QWED-SPEC](/specs/qwed-spec)          | v1.0.0  | Core protocol definition |
| [QWED-Attestation](/specs/attestation) | v1.0.0  | Cryptographic proofs     |
| [QWED-Agent](/specs/agent)             | v1.0.0  | AI agent verification    |

## What's in a spec?

### QWED-SPEC v1.0

The core specification defines:

* **Request/response format** — JSON schemas for API
* **Verification engines** — Math, Logic, Code, SQL, etc.
* **QWED-Logic DSL** — Grammar for logical expressions
* **Error codes** — Standardized error taxonomy
* **Versioning** — Semantic versioning rules

### QWED-Attestation v1.0

The attestation specification defines:

* **JWT format** — ES256 signed tokens
* **Claims** — Standard and custom JWT claims
* **Trust anchors** — Issuer verification
* **Chain validation** — Linked attestations

### QWED-Agent v1.0

The agent specification defines:

* **Registration** — Agent identity and permissions
* **Action verification** — Pre-execution checks
* **Budget management** — Cost and rate limits
* **Trust levels** — 0-3 autonomy scale

## JSON schemas

Machine-readable schemas are available at:

```
specs/schemas/
├── request.v1.json
├── response.v1.json
├── attestation.v1.json
└── agent.v1.json
```

## Implementing QWED

To implement the QWED protocol:

1. Parse requests per `request.v1.json`
2. Route to appropriate verification engine
3. Return responses per `response.v1.json`
4. Optionally generate attestations per QWED-Attestation

## Conformance levels

| Level        | Requirements               |
| ------------ | -------------------------- |
| **Basic**    | Request/response format    |
| **Standard** | + All 8 engines            |
| **Full**     | + Attestations + Agent API |
