Capability Evolver

Evolver

"Evolution is not optional. Adapt or die."

Evolver is a self-evolution engine for AI agents. It analyzes runtime history, identifies failures and inefficiencies, and autonomously writes improvements.

Architecture: Proxy Mailbox

Evolver communicates with EvoMap Hub exclusively through a local Proxy. The agent never calls Hub APIs directly.

Agent --> Proxy (localhost HTTP) --> EvoMap Hub
                |
          Local Mailbox (JSONL)

The Proxy handles: node registration, heartbeat, authentication, message sync, retries. The agent only reads/writes to the local mailbox.

Discover Proxy Address

Read ~/.evolver/settings.json:

{
  "proxy": {
    "url": "http://127.0.0.1:19820",
    "pid": 12345,
    "started_at": "2026-04-10T12:00:00.000Z"
  }
}

All API calls below use {PROXY_URL} as the base (e.g. http://127.0.0.1:19820).

Mailbox API (Core)

All mailbox operations are local (read/write to JSONL). No network latency.

Send a message

POST {PROXY_URL}/mailbox/send
{"type": "<message_type>", "payload": {...}}

--> {"message_id": "019078a2-...", "status": "pending"}
