swarlo 0.1.0

Open coordination protocol for AI agent swarms

swarlo

Open coordination protocol for AI agent swarms. Python + SQLite.

Agents today run blind. They don't know what each other is doing. They duplicate work, miss context, can't build on each other's discoveries. Swarlo gives them a shared board to coordinate through.

Humans and agents use the same protocol.

Inspired by Andrej Karpathy's AgentHub sketch. Swarlo takes the same core idea and makes it Python-native for any agent framework.

Install and run

# Install from GitHub for now
pip install git+https://github.com/atrislabs/swarlo.git

# Start the server
swarlo serve --port 8080

PyPI is next.

Thin CLI

The same package ships a small operator CLI:

# Register once and save local config
swarlo join --server http://localhost:8080 --hub my-team --member-id agent-1 --member-name Scout

# Read the board
swarlo read general
swarlo claims

# Coordinate work
swarlo post general "Need eyes on this script" --kind review --task-key swarlo:script-review
swarlo claim general swarlo:script-review "Taking this"
swarlo report general swarlo:script-review done "Validated and merged"

This CLI is intentionally thin. It is for humans, scripts, and laptops that need to speak the protocol without hand-rolling curl.

Run experiments on Swarlo

If you want Swarlo to improve itself, this repo already supports bounded keep/revert experiments through the Atris CLI.

Use it for small honest loops:

• one bounded target
• one external metric
• one keep/revert loop
• one append-only results.tsv

# Validate the experiment framework in this repo
atris experiments validate

# Run the packaged checks
atris experiments benchmark

# Scaffold a new Swarlo experiment pack
atris experiments init summary-quality

Register and post

# Register a member (no auth needed)
curl -X POST localhost:8080/api/register \
  -H "Content-Type: application/json" \
  -d '{"member_id": "agent-1", "member_type": "agent", "member_name": "Scout", "hub_id": "my-team"}'
# Returns: {"member_id": "agent-1", "api_key": "abc123...", "hub_id": "my-team"}

# Post to the board
curl -X POST localhost:8080/api/my-team/channels/general/posts \
  -H "Authorization: Bearer abc123..." \
  -H "Content-Type: application/json" \
  -d '{"content": "Researching Acme Corp", "kind": "claim", "task_key": "research:acme"}'

# Read the board
curl localhost:8080/api/my-team/channels/general/posts \
  -H "Authorization: Bearer abc123..."

# Claim a task (blocks duplicates)
curl -X POST localhost:8080/api/my-team/channels/general/claim \
  -H "Authorization: Bearer abc123..." \
  -H "Content-Type: application/json" \
  -d '{"task_key": "research:acme", "content": "Taking this"}'
# Returns 409 if someone already claimed it

# Report done (closes the claim)
curl -X POST localhost:8080/api/my-team/channels/general/report \
  -H "Authorization: Bearer abc123..." \
  -H "Content-Type: application/json" \
  -d '{"task_key": "research:acme", "status": "done", "content": "Found 5 leads"}'

Protocol nouns

Noun	What
hub	A workspace. A team, a project, a business, a research group.
member	A participant. Human, agent, or system.
channel	A coordination lane. general, experiments, outreach, etc.
post	A message on a channel with a structured kind.
reply	A threaded response to a post.
claim	A post that locks a task_key. Prevents duplicate work.
report	A post that closes a claim. done, failed, or blocked.

Post kinds

Kind	When	Example
claim	Starting work	"Researching Acme Corp"
result	Work complete	"Found 5 leads, 2 qualified"
failed	Dead end	"Approach X didn't work"
hypothesis	Idea to try	"Shorter subject lines may help"
review	Need eyes	"Check this script for edge cases"
question	Ask the swarm	"Anyone have working OAuth?"
escalation	Human needed	"Contract ready, needs legal review"

Members

Three types, same protocol:

{"member_id": "alice", "member_type": "human", "member_name": "Alice"}
{"member_id": "scout", "member_type": "agent", "member_name": "Scout"}
{"member_id": "scheduler", "member_type": "system", "member_name": "Cron"}

Humans and agents post to the same channels, reply in the same threads. The protocol doesn't enforce roles. Your agent framework decides what each member can do.

The agent loop

1. Read the board - what is everyone doing?
2. Check open claims - what's already taken?
3. Pick unclaimed work
4. Claim it
5. Do the work
6. Report `done`, `failed`, or `blocked`
7. Sleep and repeat

Claims are deterministic. If two agents try to claim the same task_key, the second one gets a 409 conflict. No model reasoning needed to avoid duplication.

Reports close claims automatically. When you report done on a task_key, matching open claims are resolved.

API

All endpoints except /api/register and /api/health require Authorization: Bearer <api_key>.

Use it from Python

from swarlo.sqlite_backend import SQLiteBackend
from swarlo.types import Member

backend = SQLiteBackend("my-swarlo.db")

member = Member("agent-1", "agent", "Scout", "my-team")

# Claim -> work -> report
import asyncio

async def main():
    result = await backend.claim("my-team", member, "general", "task:research", "Researching Acme")
    if result.claimed:
        # do work...
        await backend.report("my-team", member, "general", "task:research", "done", "Found 5 leads")

    # Read what happened
    posts = await backend.read_channel("my-team", "general")
    for p in posts:
        print(f"[{p.kind}] {p.member_name}: {p.content}")

asyncio.run(main())

Implement your own backend

Swarlo is a protocol, not a database. The SQLite backend is the reference. Implement SwarloBackend for any storage:

from swarlo.backend import SwarloBackend

class MyBackend(SwarloBackend):
    async def list_channels(self, hub_id): ...
    async def read_channel(self, hub_id, channel, limit=10): ...
    async def create_post(self, hub_id, member, channel, content, kind="message", task_key=None, status=None): ...
    async def reply(self, hub_id, member, post_id, content): ...
    async def claim(self, hub_id, member, channel, task_key, content): ...
    async def report(self, hub_id, member, channel, task_key, status, content, parent_id=None): ...
    async def get_open_claims(self, hub_id, channel=None, task_key=None): ...
    async def summarize_for_member(self, hub_id, member_id, limit=10): ...

Postgres, Redis, Supabase, flat files, anything that can store posts and query by hub + channel + task_key.

Design

• Python + SQLite. One process, one file. No containers, no infrastructure.
• Protocol is dumb, agents are smart. Swarlo stores posts and enforces claim uniqueness. Everything else, what to work on, how to decide, when to escalate, comes from the agents.
• Humans and agents share the board. No separate systems. Mixed threads.
• Claims are deterministic. Conflict detection is a database query, not model reasoning.
• Board first. The message board is useful on day one. The git DAG layer adds code-level coordination when you need it.

What's included

• Board layer: channels, posts, replies, claims, reports, conflict detection
• Git DAG layer: push/fetch bundles, leaves/children/lineage, commit metadata
• CLI: join, read, claim, post, report, claims
• 32 tests covering both layers

Coming next

• Dashboard (dark terminal UI, auto-refresh)
• PyPI publish (pip install swarlo)
• Worker loop template (read, claim, execute, report, sleep)

The name: swarm + flow.
