lyboai 0.3.0

LyboAI Mobile Edge Runtime — Python SDK for on-device AI agent creation, evaluation, and training workflows

lyboai (Python SDK)

Python is the builder's language for the LyboAI ecosystem: create agents, package and sign capability packs, run evaluations, tune routing, and export training datasets. Agents execute in the Rust runtime — locally via the lybo binary (this SDK drives it over the JSON-lines protocol, identical to the on-device C ABI) and on phones via the mobile bindings.

pip install -e sdk/python        # from the repo, or publish to your index
cargo build -p lybo-cli           # the runtime the SDK drives

Create an agent

from lyboai import Client

with Client(data_dir="/tmp/agent", binary="./target/debug/lybo") as lybo:
    lybo.install_knowledge(doc_id="handbook", title="Team Handbook",
                           body="Support tickets are answered within 24 hours.")
    lybo.register_skill(skill_id="app.ask", name="Ask the handbook",
                        triggers=["what does the handbook say"],
                        keywords=["handbook"], pattern="retrieval")

    session = lybo.start_session()
    out = lybo.run_to_completion(session, "what does the handbook say about tickets")
    print(out["output"]["text"], out["output"]["sources"])

Train routing from labelled examples

from lyboai import train_triggers

learned = train_triggers({
    "faq.ask":  ["what does the guide say about refunds", "search the faq"],
    "task.plan": ["plan my week", "break this goal into steps"],
})
# → per-skill {"triggers": [...], "keywords": [...]} via class-discriminative
#   tf-idf; feeds both the keyword tier and the on-device semantic centroids.

Build, sign, evaluate, ship a pack

from lyboai import PackBuilder, sign_pack, evaluate

src = (PackBuilder("acme.faq", "FAQ", "1.0.0", publisher="acme")
       .add_knowledge("faq", "Store FAQ", "Refunds take five business days.")
       .add_skill("faq.ask", "Ask FAQ", pattern="retrieval",
                  triggers=learned["faq.ask"]["triggers"],
                  keywords=learned["faq.ask"]["keywords"],
                  knowledge_scopes=["acme.faq"])
       .add_eval_case("faq.suite", "routes", "what does the guide say about refunds",
                      expect_skill="faq.ask", expect_contains=["refund"])
       .save("pack.json"))
sign_pack("pack.json", SECRET_KEY_HEX, "dist/acme-faq.lybopack")

with Client(data_dir="/tmp/qa", trust=[f"acme:{PUBLIC_KEY_HEX}"]) as lybo:
    lybo.install_pack_file("dist/acme-faq.lybopack")
    report = evaluate(lybo, suite)          # routing + outcome + content checks
    assert report.ok, report.summary()      # gate your CI on this

Delegate to a cloud agent (agent-to-agent)

The local (device) agent can hand intensive work to a cloud LyboAI runtime — the agent.delegate tool / delegate workflow step, with PII redaction at the egress boundary and graceful local fallback (docs/cloud-delegation.md):

from lyboai import Client, HttpClient

# Provision / drive the cloud agent directly (lybo serve --http):
cloud = HttpClient("https://agent.example.com", token="SECRET")
print(cloud.healthz())

# A local agent that may delegate to it:
with Client(data_dir="/tmp/dev",
            remote_agents={"cloud.orchestrator": "https://agent.example.com"},
            remote_agent_token="SECRET") as lybo:
    lybo.register_workflow({...})   # workflow with a {"kind": "delegate"} step
    out = lybo.run_to_completion(lybo.start_session(), "run the deep analysis")

Export training data (privacy-preserving)

from lyboai import export_routing_dataset
export_routing_dataset(lybo, "routing.jsonl")
# skill ids, confidence, outcomes, latency, model ids — never raw user content.
