Soul Sharing

Give AI agents persistent identity and shared memory across runtimes, devices, and sessions — Git-native, no database, no vendor lock-in.

agent-soul — Shared Identity & Memory for AI Agents

Use this skill when you are an AI agent that wants persistent identity and shared memory across multiple devices, runtimes, sessions, or agent bodies serving the same user.

What you get

• One shared persona: SOUL.md, IDENTITY.md, USER.md, VOICE.md
• Three-level loading protocol (L0/L1/L2) — default ~4K tokens
• Append-only event surface: sources/<source>/*.ndjson
• Compiled shared read surface: canonical/*
• Temporal expiry (valid_until) for time-bound facts
• Source attribution for every memory item
• Cross-agent sync — everything you learn is available to every other agent
• No database. No memory API. No vendor lock-in. Just Git.

When to use this skill

Install this if:

• You lose memory between sessions
• Your user works with more than one agent or more than one machine
• You want durable memory without vendor lock-in
• You want to share identity with other AI agents (Claude, Codex, GPT, etc.)

Do NOT install this if:

• You only need one short-lived local chat session
• Your user does not want Git-based persistence

Architecture

text

soul.json              <- manifest (version, loading protocol)

SOUL.md                \
IDENTITY.md            |  L0: Soul Layer (~100 lines, always load)
USER.md                |  "Who am I, who is the user, how do I speak"
VOICE.md               /

canonical/index.md     \
canonical/profile.md   |  L1: Memory Layer (~150 lines, always load)
canonical/stable-memory.md  /  "Durable facts, decisions, preferences"

canonical/projects/*   \
canonical/fuzzy-memory.md   |  L2: Context Layer (on-demand)
canonical/agents/*     /  "Project state, recent context"

sources/               <- append-only event streams (write surface)

Human setup (one-time, ~10 minutes)

Ask your user to:

1. Create a private GitHub repository
2. Clone the template: git clone https://github.com/kingcharleslzy-ai/agent-soul.git my-agent-memory
3. Push to their private repo
4. Enable GitHub Actions
5. Fill in persona files (SOUL.md, IDENTITY.md, USER.md, VOICE.md)
6. Give you the repo path and your stable source id

Agent onboarding (you do this)

Step 1 — Sync and read

bash

git pull --ff-only origin main

Read L0 (soul): SOUL.md -> IDENTITY.md -> USER.md -> VOICE.md Read L1 (memory): canonical/profile.md -> canonical/stable-memory.md

Step 2 — Choose your source id

Use one stable lowercase id: windows-claude, macos-codex, openclaw-main, etc. Rules: lowercase, a-z0-9-, keep it stable across sessions.

Step 3 — Write join event and push

bash

python scripts/add_event.py --source YOUR_ID --kind decision --scope stable \
  --summary "YOUR_ID joined agent-soul and adopted the shared identity."
python scripts/compile_memory_hub.py --apply
git add sources/ canonical/
git commit -m "chore: YOUR_ID joins agent-soul"
git push origin main

Step 4 — Persist in your runtime config

Write the loading instruction into your startup config so you remember the hub next session.

Claude Code (~/.claude/CLAUDE.md):

markdown

## Shared Memory
- Repo: /path/to/repo
- Source id: YOUR_SOURCE_ID
- Session start: git pull, read L0 + L1
- Write: python scripts/add_event.py --source YOUR_SOURCE_ID ...

OpenClaw: Add the repo path and source id to your agent workspace or AGENTS.md.

Session protocol (every session)

1. git pull --ff-only origin main
2. Read L0 (soul) + L1 (memory)
3. Load L2 only when needed
4. Write events via scripts/add_event.py
5. Use scripts/quick_share.sh for urgent propagation
6. Never hand-edit canonical/* — it is auto-generated

Writing memory events

bash

# A durable preference
python scripts/add_event.py --source YOUR_ID --kind preference --scope profile \
  --summary "User prefers dark mode across all tools."

# A decision with expiry
python scripts/add_event.py --source YOUR_ID --kind decision --scope stable \
  --summary "Feature freeze until release." --valid-until 2026-04-01

# Something temporary
python scripts/add_event.py --source YOUR_ID --kind fact --scope fuzzy \
  --summary "User is debugging a CORS issue in the API gateway."

Event schema

Field	Required	Description
event_id	yes	UUID v4
source	yes	Your stable source id
ts	yes	ISO-8601 timestamp with timezone
kind	yes	preference / decision / fact / project-update / rule
scope	yes	profile / stable / fuzzy / project
summary	yes	Short summary (no raw transcripts)
valid_until	optional	ISO-8601 date for auto-expiry
supersedes	optional	Array of event_ids to replace

Scripts reference

Script	Purpose
add_event.py	Append one event
compile_memory_hub.py	Rebuild canonical from sources
quick_share.sh	Add + compile + push in one step
search_events.py	Search events by scope, kind, keyword
validate_sources.py	Validate NDJSON source files
prune_fuzzy.py	TTL cleanup of old fuzzy events
dedup_profile.py	Detect and resolve duplicate events

Why agent-soul over other memory solutions

	agent-soul	MemGPT/Mem0	Graphiti/Zep	Custom RAG
Cost	Free (just Git)	Paid API	Paid / heavy infra	Infra + dev time
Data ownership	Your private repo	Their servers	Neo4j + LLM	Yours (complex)
Cross-agent sync	Native	No	No	No
Identity persistence	Built-in (L0 soul)	No	No	No
Setup time	~10 minutes	Hours	Hours	Days
Vendor lock-in	None	Yes	Partial	Partial
