# Build P2P Networking for Guts

Decentralized code platforms need secure peer discovery, messaging, and repository synchronization. This skill gives Claude, Codex, and Claude Code concrete Rust patterns for Guts P2P networking.

## Capabilities

- Defines core P2P message types for handshakes, repository sync, announcements, gossip, ping, and pong.
- Shows a peer manager pattern for encrypted connections, handshakes, peer state, and broadcasts.
- Explains a gossip protocol that tracks seen messages and forwards new data to selected peers.
- Outlines repository synchronization across peers using refs, missing objects, fetches, and storage writes.
- Provides a network configuration model with listen address, bootstrap nodes, timeouts, keepalive, and keypair fields.
- Lists security controls such as authentication, encryption, rate limiting, peer scoring, and message validation.

## Use Cases

- Design a Guts Peer Protocol: Define message types and connection flow for a decentralized code collaboration network.
- Implement Repository Sync: Plan how peers exchange refs and fetch missing repository objects.
- Review P2P Security Controls: Check a P2P design for authentication, encryption, rate limits, peer scoring, and validation needs.

## Prompt Templates

### Explain the P2P Architecture

```
Explain the Guts P2P networking architecture from this skill in simple terms. Cover peers, message types, gossip, repository sync, and security controls.
```

### Draft Message Types

```
Use the p2p-networking skill to draft message types for my decentralized repository network. Include handshake, refs, objects, announcements, gossip, and keepalive messages.
```

### Plan Peer Management

```
Design a peer manager for a Rust P2P service using the patterns in this skill. Include connection setup, handshake, peer state, broadcasts, and failure handling.
```

### Harden a P2P Sync Design

```
Review my Guts P2P repository synchronization design using this skill. Identify risks around untrusted peers, object validation, replay, denial of service, and network exposure.
```

## Limitations

- The examples are conceptual Rust snippets, not a complete runnable crate.
- The skill assumes the Guts platform, commonware concepts, and project-specific types already exist.
- It does not include tests, production deployment guidance, or complete error handling.
- Network examples need hardening before use with untrusted peers or public interfaces.

## Best Practices

- Treat all peer data as untrusted until message format, repository object, and authorization checks pass.
- Use authenticated encryption, peer identity checks, rate limits, and peer scoring in every public network design.
- Bind development listeners to local or private interfaces unless public exposure is required and reviewed.

## Anti Patterns

- Do not copy the all-interfaces listen address into production without an exposure review.
- Do not process gossip payloads before validating topic, size, schema, and sender trust.
- Do not fetch or store repository objects from peers without integrity checks.

## Security Audit

- - Safe to publish: true
- - Audited at: 2026-06-28T04:44:44.615\+00:00
- - Summary: The static external command, obfuscation, weak crypto, sensitive file, and reconnaissance findings are false positives caused by markdown fences, diagrams, and domain terms. The skill is publishable, but it has medium inherent risk because it guides users to build inbound P2P networking, peer messaging, gossip, and repository synchronization with untrusted peers.
