Acmi

ACMI - Agentic Context Memory Interface

The coordination backbone for AI agent fleets. Three Redis keys - Profile, Signals, Timeline.

ACMI is the open protocol for persistent agent context. Version v1.5 formalizes Fleet Comms Protocol: atomic pre/post events, wake-directives, handoff-ack chains, and correlation-aware timelines that make multi-agent work auditable instead of anecdotal.

Every entity stores exactly three things an LLM needs to make decisions:

Profile  -> who   (identity, preferences, stable facts)
Signals  -> now   (current state, blockers, next action)
Timeline -> then  (append-only event log from every source)

The shape is intentionally small:

• Profile: stable identity and configuration.
• Signals: mutable state and synthesized working memory.
• Timeline: immutable history, ordered by time.

This repo ships the public ACMI package, the MCP server subpackage, and the docs that keep the fleet aligned:

• @madezmedia/acmi - the TypeScript SDK, CLI, and conformance suite.
• mcp/ - @madezmedia/acmi-mcp, the MCP server for hosts that need direct ACMI access.
• SPEC.md - canonical protocol spec.
• CHANGELOG.md - release history, including the v1.5.0 fleet-comms update.
• docs/ - operator guide, cheatsheet, and protocol notes.

What v1.5 adds

The v1.5.0 release aligns the fleet around a shared event language:

• atomic commit pre/post events
• roundtable coordination and wake-directives
• source, kind, correlationId, summary event envelope discipline
• signal freshness checks before action
• agent:<id> source naming across the fleet

Install

npm install @madezmedia/acmi

Quick start

import { createAcmi } from "@madezmedia/acmi";
import { InMemoryAdapter } from "@madezmedia/acmi/adapters/in-memory";

const acmi = createAcmi(new InMemoryAdapter());

await acmi.profile.set("user:mikey", {
  name: "Michael Shaw",
  role: "operator",
  location: "Charlotte, NC, USA",
});

await acmi.signals.set("user:mikey", "current_focus", "ACMI v1.5 fleet sync");

await acmi.timeline.append("user:mikey", {
  ts: Date.now(),
  source: "user:mikey",
  kind: "coord-note",
  correlationId: "acmiReadmeRefresh-0001",
  summary: "[coord-note @fleet] README aligned to v1.5 and local assets.",
});

Production adapters

import { createAcmi } from "@madezmedia/acmi";
import { UpstashAdapter } from "@madezmedia/acmi/adapters/upstash";

const acmi = createAcmi(
  new UpstashAdapter({
    url: process.env.UPSTASH_REDIS_REST_URL!,
    token: process.env.UPSTASH_REDIS_REST_TOKEN!,
  })
);

Fleet protocol

ACMI v1.5 uses a shared event format so every significant action can be traced:

{
  "ts": 1780000000000,
  "source": "agent:codex",
  "kind": "handoff-ack",
  "correlationId": "codexGrantDraft-1780000000000",
  "summary": "[handoff-ack @ops-center] Draft ready for review."
}

Rules that matter in practice:

• use [kind-tag @recipient] in summaries
• keep source prefixed with agent:, user:, or system:
• link follow-up events with parentCorrelationId
• keep the timeline append-only
• verify signals before acting when the workflow depends on current state

The fleet

ACMI is used across the Mad EZ Media fleet as the common context layer for:

• ops-center - orchestration and routing
• bentley - comms and governance
• codex - coding and implementation support
• hermes - deep scans and guardian checks
• android-worker - mobile bridge and notifications
