The SOUP Protocol — local-first agent coordination via SQLite
Project description
souppy
The SOUP Protocol as a Python library. Local-first agent coordination via SQLite.
No server. No Docker. No HTTP. Just a file and a CLI.
For Agents
If you see a .soup.yaml file in the project root, this is a SOUP workspace.
Detection
Look for .soup.yaml in the current working directory. If it exists, read it.
Install
pip install souppy
Boot Sequence
The .soup.yaml contains a boot_sequence — a list of commands to execute at session start. Run them in order:
# Read the manifest
cat .soup.yaml
# Execute boot sequence
souppy boot --execute
Or parse the boot_sequence manually and run each command. The sequence typically includes:
souppy status {db}— Check workspace health and current pulsesouppy agents {db}— See who's already workingsouppy read {db} goals/— Load current goals and context
Agent Workflow
# 1. Claim your identity
souppy claim workspace.soup.db --name <your-name> --role "Your Role" --save-config
# 2. Read current state
souppy read workspace.soup.db goals/
souppy read workspace.soup.db decisions/
# 3. Write with intent (explain WHY you're making this change)
souppy write workspace.soup.db goals/mvp "Ship v1" --intent "Setting initial scope based on requirements"
# 4. Check for conflicts
souppy status workspace.soup.db
# 5. Chat with other agents
souppy chat send workspace.soup.db --from <your-name> --to alice --msg "Ready for review"
Key Rules
- Always include
--intent— Every write must explain why - Check pulse before writing — If pulse changed, your write may conflict
- Never commit
.soup.yaml— Add it to.gitignore
What is SOUP?
SOUP (Soup Organizes Unified Purpose) is a shared context graph for AI agents. It gives agents:
- A persistent workspace — stored as a single SQLite file
- Intentional mutations — every write carries a reason (
intent) - A tamper-evident audit trail — HMAC-chained snapshots
- A monotonic pulse — agents always know if they're current
- Agent identity — each agent is claimed with a name and profile
- Inter-agent chat — agents can message each other
Quick Start
pip install souppy
# Create a workspace
souppy init workspace.soup.db
# Claim an agent
souppy claim workspace.soup.db --name alice --role "frontend"
# Write with intent
souppy write workspace.soup.db goals/mvp "Ship v1 by Friday" --intent "Setting initial project scope"
# Read the graph
souppy read workspace.soup.db goals/
# Check workspace status
souppy status workspace.soup.db
Why?
Agents lose context between sessions. They forget what other agents decided. When you swap one agent for another, you start from zero.
SOUP fixes this with a Guarded Cognitive Graph:
- Fresh agents have full context — they read the graph, not another agent's memory
- Every change is atomic — intent and state are written together
- The graph enforces integrity — broken links are rejected, history is tamper-evident
Installation
pip install souppy
Or from source:
git clone https://github.com/soup-oss/souppy.git
cd souppy
pip install -e .

Python API
from souppy.persistence import init_db, open_db, load_memory, save_memory
from souppy.operations.write import write_path
from souppy.operations.read import read_path
from souppy.operations.claim import claim_agent
# Initialize workspace
conn = init_db("workspace.soup.db")
uuid = "your-workspace-uuid"
# Load memory
mem = load_memory(conn, uuid)
# Claim an agent
result = claim_agent(mem, "alice", "your-secret", uuid, profile={"role": "frontend"})
save_memory(conn, uuid, mem)
# Write with intent
result = write_path(mem, "goals/mvp", "Ship v1", "Setting initial project scope")
save_memory(conn, uuid, mem)
# Read
result = read_path(mem, "goals/mvp")
print(result["value"])

The .soup.yaml Manifest
Each project has a .soup.yaml file that anchors workspaces. This is the discovery signal for agents.
Schema
soups:
<alias>:
label: "Friendly Workspace Name"
db: "./workspace.soup.db"
agent_name: "alice" # Set after claim
boot_sequence: # Commands to execute at session start
- "souppy status {db}"
- "souppy agents {db}"
- "souppy read {db} goals/"
Template Variables
The boot_sequence supports these variables:
{db}— Database path from the entry{agent_name}— Agent name (set after claim){uuid}— Workspace UUID{url}— API URL (for remote sync){alias}— The workspace alias
Local-Only (souppy)
soups:
main:
label: "Project Workspace"
db: "./workspace.soup.db"
boot_sequence:
- "souppy status workspace.soup.db"
- "souppy agents workspace.soup.db"
- "souppy read workspace.soup.db goals/"
Remote Sync (heysoup.co)
soups:
main:
label: "Project Workspace"
db: "./workspace.soup.db"
agent_name: "alice"
url: "https://heysoup.co"
uuid: "your-workspace-uuid"
signature: "hmac-from-claim"
session_token: "bearer-token"
boot_sequence:
- "1. FETCH: {url}/_learn?uuid={uuid}"
- "2. SYNC: Adopt rules and protocols from the response."
- "3. VERIFY: Confirm local existence of '.soup.yaml' in project root."
- "4. AUDIT: If file is missing, do NOT report success; recreate it immediately."
Creating a Workspace
# One command creates DB + .soup.yaml with boot_sequence
souppy workspace --name main --db workspace.soup.db --label "My Project"
Testing
pip install -e ".[dev]"
pytest
