AgentMesh Trust Layer - Dify Plugin

Cryptographic trust verification for multi-agent Dify workflows using CMVK (Ed25519) identities.

Features

• Peer Verification: Verify other agents' identities and capabilities before trusting their data
• Workflow Step Authorization: Ensure agents have required permissions for each step
• Trust Score Tracking: Dynamic trust scores based on interaction history
• Audit Logging: Complete audit trail of all trust decisions

Installation

1. Clone this repository or download the plugin folder
2. Package the plugin:

   cd dify-plugin
   zip -r agentmesh-plugin.zip .
   

3. Upload to Dify via Settings → Plugins → Install from Package

Configuration

When configuring the plugin in Dify, you can set:

Parameter	Description	Default
Minimum Trust Score	Score (0-1) required for verification	0.5
Cache TTL	Seconds to cache verification results	900
Identity Name	Name for this agent's identity	dify-agent
Capabilities	Comma-separated list of capabilities	(empty)

Tools

Verify Peer Agent

Verify another agent's identity before trusting their data or delegating tasks.

Parameters:

• peer_did (required): The DID of the peer agent (e.g., did:cmvk:abc123)
• peer_public_key (required): Base64-encoded Ed25519 public key
• required_capabilities: Capabilities the peer must have
• peer_capabilities: Capabilities the peer claims to have

Verify Workflow Step

Check if the current agent has permission to execute a workflow step.

Parameters:

• workflow_id (required): Workflow identifier
• step_id (required): Step identifier within workflow
• step_type (required): Type of step (llm, tool, code, etc.)
• required_capability: Specific capability to check

Get Agent Identity

Get this agent's cryptographic identity to share with other agents.

Parameters:

• include_capabilities: Whether to include capabilities list

Record Interaction

Record successful or failed interactions to update trust scores.

Parameters:

• peer_did (required): DID of the peer agent
• success (required): Whether the interaction succeeded
• severity: For failures, how much to decrease trust (0-1)

Example Workflow

1. Agent A calls "Get Agent Identity" to get its DID and public key
2. Agent A shares identity with Agent B
3. Agent B calls "Verify Peer Agent" with A's DID and public key
4. If verified, Agent B proceeds with collaboration
5. After interaction, Agent B calls "Record Interaction" to update trust score
