plurigrid OpenClaw → Goblins Adapter
Study: elizaOS/openclaw-adapter
The openclaw-adapter bridges ElizaOS plugins into OpenClaw via:
| File | ElizaOS → OpenClaw |
|---|---|
action-to-tool.ts |
Action → Tool (params: JSON Schema → TypeBox) |
provider-to-hook.ts |
Provider → before_agent_start hook |
service-adapter.ts |
Service → Service (eager start) |
evaluator-to-hook.ts |
Evaluator → lifecycle hooks |
runtime-bridge.ts |
IAgentRuntime → RuntimeBridge shim |
in-memory-store.ts |
IDatabaseAdapter → LRU InMemoryStore (10K cap) |
schema-converter.ts |
JSON Schema → TypeBox + known wallet schemas |
Critical pattern: RuntimeBridge is a shim, not a full runtime embed.
This Adapter: ElizaOS → Goblins OCapN
| ElizaOS | Goblins | Why |
|---|---|---|
| Action | ^action-actor | Caps = authority (not ACL) |
| Provider | ^provider-cap | Read-only attenuated ref (POLA) |
| Service | ^service-actor in vat | Isolation via event loop |
| Evaluator | ^guard-actor | Proxy composition |
| IAgentRuntime | ^vat-bridge | Transactional actor state |
| IDatabaseAdapter | Actor state (bcom) | Automatic rollback |
| JSON Schema | Syrup record descriptor | Wire-native |
| OAuth session | CapTP session (Ed25519) | Structural authority |
| /eliza route | Bootstrap object (pos 0) | Single entry point |
| Tool schema | Syrup record | ^schema-bridge |
Security Model Upgrade
MCP/ElizaOS: ambient authority
token → role → permissions → action
(confused deputy attacks possible)
Goblins/OCapN: structural authority
ref = authority (POLA)
(confused deputy impossible by construction)

GF(3)
Actions = +1 (generative — create capabilities)
Providers = -1 (constraining — read-only attenuation)
Services = 0 (ergodic — background transport)
Adapter enforcer: registration sum ≡ 0 (mod 3).
Usage
(define-values (vat bridge schema session gf3)
(spawn-goblins-adapter "my-agent" settings))
;; Register ElizaOS-shaped plugin
($ bridge register-plugin plugin-spec)
;; Invoke tool (CapTP bootstrap)
($ bridge invoke "tool-name" params)
;; Bridge MCP call → CapTP deliver
($ session mcp-call->deliver sid "tool" params)
