daimon-protocol 0.2.0.dev0

Python SDK for the Daimon protocol — sovereign personal AI

daimon — Python SDK

Thin Python client over the Daimon daemon's Unix-socket JSON-RPC surface (SPEC §6.1). Mirrors the Go cmd/daimon CLI's wire-level behaviour: one connection per RPC, no pipelining, JSON-RPC 2.0.

Status: v0.1.0 — first GA release. Identity, memory, provider (list / invoke / stream), and activity verbs all surfaced.

Install

From PyPI:

pip install daimon-protocol

From a checkout of the Daimon repo:

pip install -e sdk/python

The PyPI distribution name is daimon-protocol because the unqualified daimon name on PyPI is held by an unrelated dormant package, and daimon-sdk / daimon-client belong to other active projects. The import name remains daimon — from daimon import Client works regardless of how you installed it.

Use

The SDK assumes a running daimon daemon on the local machine, reachable via the same socket path the Go CLI uses ($DAIMON_HOME/daimon.sock, with the same long-path fallback rules). Start the daemon first:

daimon unlock

Then:

from daimon import Client

client = Client()                                  # resolves $DAIMON_HOME
print(client.identity.get())                       # {"did": "did:key:..."}

# memory.Kind.Valid() accepts: "fact", "preference", "task", "observation"
mid = client.memory.write(kind="fact", content="the sky is blue")
print(mid)                                         # {"id": "01K..."}

mem = client.memory.read(mid["id"])
hits = client.memory.search("sky")                 # [{...mem, "score": 0.7}, ...]
all_mems = client.memory.list()                    # search with empty query

# provider verbs
providers = client.provider.list()
env = client.provider.invoke(
    provider="ollama",
    model="llama3.2:latest",
    messages=[{"role": "user", "content": "hi"}],
)
print(env["response"]["content"])

# streaming — yields delta strings; final envelope on .final
stream = client.provider.stream(
    provider="ollama",
    model="llama3.2:latest",
    messages=[{"role": "user", "content": "count to 3"}],
)
for delta in stream:
    print(delta, end="", flush=True)
print()
print("usage:", stream.final["response"]["usage"])

# activity verbs (audit trail)
client.activity.append(kind="custom.event", payload={"n": 1})
entries = client.activity.query(limit=20)
result = client.activity.verify()                  # {"verified": N, "ok": True}

Errors

from daimon import DaemonNotRunning, DaemonLocked, RPCError

try:
    client.memory.write(kind="fact", content="x")
except DaemonNotRunning:
    # daimon binary isn't serving on this $DAIMON_HOME
    ...
except DaemonLocked:
    # daemon is running but `daimon unlock` hasn't been called
    ...
except RPCError as e:
    # any other JSON-RPC error from the daemon
    print(e.code, e.message, e.data)

Development

cd sdk/python
pip install -e .[dev]
pytest

The test suite uses a stub Unix-socket daemon (no real keys, no real storage) plus optional smoke tests against a live daimon when one is running.
