mubit-sdk 0.6.0

Public unified Mubit SDK with one Client facade

mubit-sdk

Canonical Python SDK for MuBit. Durable memory + continual learning for AI agents.

Full documentation: https://docs.mubit.ai

Install

pip install mubit-sdk

Quickstart

import os

from mubit import Client

client = Client(
    transport=os.getenv("MUBIT_TRANSPORT", "auto"),
    run_id="sdk-python-demo",
    api_key=os.environ["MUBIT_API_KEY"],
)

client.remember(
    session_id="sdk-python-demo",
    agent_id="sdk-quickstart",
    content="If the replay queue stalls, checkpoint before replaying recovery.",
    intent="lesson",
    lesson_type="success",
    lesson_scope="session",
)

answer = client.recall(
    session_id="sdk-python-demo",
    query="What should I do before replaying recovery?",
    entry_types=["lesson", "rule"],
)
print(answer.get("final_answer"))

Surface model

The SDK exposes two layers:

1. mubit.learn — zero-config LLM instrumentation (auto-ingest + auto-inject + auto-reflect).
2. Flat client surface — every control-plane operation lives directly on Client. High-level helpers (remember, recall, get_context, checkpoint, reflect, record_outcome, record_step_outcome, archive, dereference, memory_health, diagnose, register_agent, list_agents, handoff, feedback, surface_strategies, forget) are richer wrappers that resolve session_id and set sensible defaults; all other ops are called as client.<op>(...).

Admin and low-level storage ops still live under client.auth.* and client.core.* for clarity.

Helper APIs accept session_id as the ergonomic alias for run_id.

Managed MuBit resources

For teams and hosted deployments, configure agents declaratively as Projects + Agent Cards with versioned prompts and skills. See Projects, Agents, Skills, Prompts for the full guide.

Projects

project = client.create_project(
    name="triage-demo",
    description="Customer-support triage pilot",
)
project_id = project["project"]["project_id"]

projects = client.list_projects()

Agent Definitions

agent = client.create_agent_definition(
    project_id=project_id,
    agent_id="triage",
    role="customer triage agent",
    system_prompt_content="You are a concise, empathetic triage agent...",
)

Prompt version lifecycle

Every agent has exactly one active prompt version and any number of candidate versions awaiting review.

# Manual edit — activates immediately.
client.set_prompt(agent_id="triage", content="...", activate=True)

# Ask the control plane to propose a candidate from recent outcomes.
resp = client.optimize_prompt(agent_id="triage", project_id=project_id)
candidate = resp["candidate"]

# Review the diff, then promote the candidate.
diff = client.get_prompt_diff(
    agent_id="triage",
    version_a_id=active_version_id,
    version_b_id=candidate["version_id"],
)
client.activate_prompt_version(
    agent_id="triage",
    version_id=candidate["version_id"],
)

See the Prompt Optimization Lifecycle recipe for the full capture → optimize → review → activate workflow.

Skills

Same shape as prompts — create_skill, optimize_skill, activate_skill_version, get_skill_diff.

Learning loop

client.register_agent(
    session_id="sdk-python-demo",
    agent_id="planner",
    role="planner",
    read_scopes=["rule", "lesson", "fact"],
    write_scopes=["lesson", "trace"],
    shared_memory_lanes=["knowledge", "history"],
)

client.checkpoint(
    session_id="sdk-python-demo",
    label="pre-compaction-1",
    context_snapshot="Planner narrowed the failure to token refresh ordering.",
)

client.record_step_outcome(
    session_id="sdk-python-demo",
    step_id="2026-04-17-route",
    step_name="routing",
    outcome="partial",
    signal=0.3,
    rationale="Routed to billing but should have gone to compliance",
    directive_hint="Check billing AND compliance scopes before routing",
)

strategies = client.surface_strategies(
    session_id="sdk-python-demo",
    lesson_types=["success", "failure"],
    max_strategies=3,
)

Exact references

archived = client.archive(
    session_id="sdk-python-demo",
    artifact_kind="patch_fragment",
    content="--- a/query.py\n+++ b/query.py\n@@ ...",
    labels=["django", "retry"],
    family="patch-repair",
)

exact = client.dereference(
    session_id="sdk-python-demo",
    reference_id=archived["reference_id"],
)

Auto-capture

For zero-friction trace capture in MAS learning loops:

from mubit.auto import instrument, observe

instrument()

@observe(name="repair-attempt")
def run_attempt():
    ...

Endpoint resolution

transport defaults to auto (gRPC primary, HTTP fallback). Resolution order:

1. Explicit endpoint / http_endpoint / grpc_endpoint constructor args.
2. Env vars MUBIT_ENDPOINT, MUBIT_HTTP_ENDPOINT, MUBIT_GRPC_ENDPOINT.
3. Shared defaults https://api.mubit.ai and grpc.api.mubit.ai:443.

See SDK Configuration for full details.
