effigy

Runtime-agnostic stack for autonomous agents. Plug any agent brain into generative tools, channels, hosting, and legal provenance — wired by default.

This repo is the developer SDK. Public surfaces:

• effigyguide.vercel.app — brand system
• effigydeck.vercel.app — master deck

Packages

Package	Purpose
@effigy/cai-spec	Common Agent Interface · 11-op TypeScript spec + Zod schemas
@effigy/adapter-hermes	Hermes runtime adapter implementing @effigy/cai-spec

Quickstart

pnpm install
pnpm -r build
pnpm --filter @effigy/examples quickstart

The quickstart runs a full init → invoke → stream → memory → shutdown round-trip against an offline fixture. No network, no model keys needed.

Develop

pnpm -r typecheck    # TypeScript strict across all packages
pnpm -r build        # tsc emits dist/ for each package
pnpm -r test         # vitest · 31 scenarios across all 11 CAI ops
