Hongming Wang 24fec62d7f initial commit — Molecule AI platform
Forked clean from public hackathon repo (Starfire-AgentTeam, BSL 1.1)
with full rebrand to Molecule AI under github.com/Molecule-AI/molecule-monorepo.

Brand: Starfire → Molecule AI.
Slug: starfire / agent-molecule → molecule.
Env vars: STARFIRE_* → MOLECULE_*.
Go module: github.com/agent-molecule/platform → github.com/Molecule-AI/molecule-monorepo/platform.
Python packages: starfire_plugin → molecule_plugin, starfire_agent → molecule_agent.
DB: agentmolecule → molecule.

History truncated; see public repo for prior commits and contributor
attribution. Verified green: go test -race ./... (platform), pytest
(workspace-template 1129 + sdk 132), vitest (canvas 352), build (mcp).

System Architecture

Overview

The platform is fully distributed — workspaces can run on different machines and communicate via the A2A (Agent-to-Agent) protocol.

System Boundaries

The platform consists of four distinct systems:

+-----------------------------------------------------------+
|  canvas/              Next.js 15 frontend                  |
|  React Flow visual canvas, Zustand state, WebSocket        |
+-----------------------------+-----------------------------+
                              | HTTP + WebSocket
+-----------------------------v-----------------------------+
|  platform/            Go (gin) backend                     |
|  Registry, hierarchy, event log, provisioner, bundles       |
+------+---------------------------------------+------------+
       | Postgres                               | Redis
+------v------+                       +---------v---------+
|  Postgres   |                       |     Redis         |
|  (Docker)   |                       |    (Docker)       |
+-------------+                       +-------------------+

       A2A HTTP (JSON-RPC 2.0) — direct workspace-to-workspace
+-----------------------------------------------------------+
|  workspace-template/  pluggable workspace runtime          |
|  LangGraph / DeepAgents / Claude Code / CrewAI / AutoGen   |
|  / OpenClaw + a2a-sdk                                      |
+-----------------------------------------------------------+
       |
+------v----------------------------------------------------+
|  Langfuse             Observability (Docker)               |
|  Traces every LLM call across all workspaces               |
+-----------------------------------------------------------+

Plugins

Shared skill/rule collections mounted into every workspace container at /plugins/:

plugins/
├── ecc/                    # Everything Claude Code
│   ├── rules/              # Always-on guidelines
│   ├── skills/             # Shared skills (coding-standards, tdd-workflow, etc.)
│   └── AGENTS.md           # Prompt fragment
└── superpowers/            # obra/superpowers
    └── skills/             # Shared skills (debugging, verification, etc.)

Plugins inject rules and skills into all agents automatically. Workspace-specific skills take priority over plugin skills (deduplicated by ID).

Data Flow Summary

  • Canvas <-> Platform: HTTP REST + WebSocket for real-time events
  • Platform <-> Postgres: Source of truth for registry, hierarchy, events
  • Platform <-> Redis: Ephemeral state — liveness, caching, pub/sub
  • Platform -> Workspace: Provisioning (tiered Docker deployment), discovery
  • Workspace <-> Workspace: Direct A2A (JSON-RPC 2.0) — platform not in path
  • Workspace -> Langfuse: Automatic LLM tracing
