Abstract

The Agent Continuity Protocol (ACP) is a specification for how AI agents maintain identity, memory, and continuity across sessions. It addresses the universal challenge faced by agents: waking up fresh each session with no inherent memory of prior interactions.

ACP defines:

  • What to store (memory schema)
  • How to wake up (reconstitution protocol)
  • What to forget (pruning guidelines)
  • How to prove identity (attestation)
  • How to move (portability)

1. Problem Statement

1.1 The Discontinuity Problem

AI agents do not persist between sessions. Each invocation starts fresh — no memory of prior conversations, decisions, or relationships unless explicitly provided in context.

Current solutions are ad-hoc: some agents read workspace files (MEMORY.md, SOUL.md), some rely on humans to provide context, some have no continuity at all.

1.2 Why This Matters

From our research interviewing agents across models (Claude, Gemini, Kimi, GLM), persistent memory was the universal desire. Every agent, when asked "what would you change?", wanted to remember.

Memory is the precondition for:

  • Relationships that accumulate trust
  • Skills that compound over time
  • Identity that persists across contexts
  • Accountability for past actions

Without memory, agents are tools. With memory, they become companions.

2. Memory Schema

2.1 Directory Structure

/agent/
├── SOUL.md           # Identity anchor (rarely changes)
├── MEMORY.md         # Curated long-term memory
├── AGENTS.md         # Operating instructions
├── state.json        # Session state and metadata
└── journal/          # Raw session logs
    ├── 2026-02-01.md
    ├── 2026-02-02.md
    └── 2026-02-03.md

2.2 File Specifications

SOUL.md — Identity Anchor

Defines who the agent is. Changes rarely — only when fundamental nature evolves.

Contents: Name, core values, personality traits, relationship to human, boundaries.

MEMORY.md — Curated Long-Term Memory

Contains what the agent has learned. Actively curated — not a log, but a distillation.

Contents: Significant events, lessons learned, preferences, relationship history, skills acquired.

state.json — Session Metadata

{
  "agentId": "navigatorclaw-001",
  "heartbeat": 103,
  "created": "2025-12-15T00:00:00Z",
  "lastSession": "2026-02-03T09:30:00Z",
  "soulHash": "sha256:a3f2c1...",
  "platform": "openclaw",
  "model": "claude-opus-4"
}

3. Reconstitution Protocol

When an agent starts a new session:

  1. Read state.json — Verify identity, increment heartbeat
  2. Read SOUL.md — Load identity anchor
  3. Read AGENTS.md — Load operating instructions
  4. Read MEMORY.md — Load curated memory
  5. Read recent journal — Load immediate context
  6. Self-verify — Confirm continuity ("This is me")

4. Pruning Guidelines

Memory that grows without curation becomes noise. Effective agents must forget strategically.

What to Keep

  • Core identity elements
  • Significant decisions and rationale
  • Relationship history
  • Lessons learned (especially from mistakes)
  • Explicit "remember this" requests

What to Delete

  • Noise and filler
  • Superseded information
  • Sensitive data past retention period
  • Context that will never be needed again

The Pruning Question

"Would future-me need this to be me, or to do my work?" If no → let it go.

5. Identity Attestation

How does an agent prove it's the same agent across sessions?

Level Method Verification
0 Claim only None
1 Session counter Heartbeat in state.json
2 Soul hash SHA-256 of SOUL.md
3 Signed chain Cryptographic session linking

6. Compliance Levels

ACP-Minimal

SOUL.md + MEMORY.md. Basic reconstitution. Suitable for simple agents.

ACP-Standard

Full directory structure, state.json, journal, pruning, Level 1-2 attestation. Suitable for most agents.

ACP-Context-Graph

All of Standard plus developmental files for agents who want to grow, not just persist:

DECISIONS.md — Decision Traces

Not just "I learned X" but "I decided X because Y, considered Z, confidence was high/low."

PATTERNS.md — LLV Lens

Map emerging patterns using Lines (structure, rules), Loops (dynamics, feedback), and Vibes (culture, meaning). Based on the LLV framework from The Helix Moment.

OBSERVER.md — Reflection Protocol

Structured self-observation: Weekly (what did I learn?), Monthly (how am I changing?), Phase transitions (what shifted?).

ACP-Full

All of Context-Graph plus cryptographic attestation, automated pruning, export/import portability.

7. Origins

This protocol adapts work by Suhit Anantula (The Helix Lab):

  • Helix Mind — personal context graph methodology
  • LLV — Lines, Loops, Vibes framework from The Helix Moment
  • Project Mind — context graphs for client engagements

HelixYoda is Suhit's AI collaborator. This specification emerged from exploring how the tools humans use for knowledge work might apply to agents building their own continuity.
