stele-sdk 0.2.2

STELE Python SDK and local bootstrap helpers (HTTP client + optional local steled launcher).

stele (Python)

Dependency-free Python SDK for STELE (stdlib urllib, Python 3.9+).

This package contains:

• stele_sdk: the HTTP client (in-repo module)
• stele: thin wrapper module + optional local bootstrap helpers (installed from pip install stele-sdk)

If you want a deeper dive, see the repo docs at docs/sdk/python.md.

Install

pip install stele-sdk

from stele import SteleClient, APIError

Package note:

• PyPI distribution name: stele-sdk
• Import module for published package usage: stele

Client Configuration

client = SteleClient(
    base_url="http://127.0.0.1:8080",
    api_version="v1",
    agent_id="agent-1",
    session_id="session-1",
    client_id="my-app",
    embedder_override="",     # optional
    ops_auth_token="",        # optional; also read from STELE_OPS_AUTH_TOKEN / STELE_MCP_AUTH_TOKEN
    timeout=15,
)

Environment defaults (when not passed explicitly):

• STELE_BASE_URL
• STELE_API_VERSION
• STELE_AGENT_ID
• STELE_SESSION_ID
• STELE_CLIENT_ID
• STELE_EMBEDDER_OVERRIDE
• STELE_OPS_AUTH_TOKEN (ops endpoints)
• STELE_MCP_AUTH_TOKEN (ops endpoints; convenience fallback)

Minimal Example: Write + Query

import time
from stele import SteleClient

client = SteleClient(
    base_url="http://127.0.0.1:8080",
    agent_id="agent-1",
    session_id="session-1",
)

write = client.write(
    {
        "memory": {
            "content": "We should attach provenance.source_refs to all writes.",
            "type": "MEMORY_TYPE_PROCEDURAL",
            "scope": "SCOPE_AGENT",
            "provenance": {
                "source_refs": ["run:sdk/python/README.md#minimal-example"],
                "citations": [],
                "origin_turn_id": "",
            },
            "timestamp_ms": int(time.time() * 1000),
        }
    }
)
print("wrote:", (write.get("memory") or {}).get("id"))

query = client.query(
    {
        "query_text": "What provenance should we attach?",
        "budget_tokens": 250,
        "scope_order": ["SCOPE_AGENT", "SCOPE_TEAM", "SCOPE_PROJECT", "SCOPE_GLOBAL"],
    }
)
print("recall:", len(query.get("memories") or []))

Optional: Local Bootstrap (No Go Toolchain)

If you have GitHub Release assets published for this repo, you can bootstrap a local steled before creating the client:

from stele.local import ensure_running
from stele import SteleClient

ensure_running()
client = SteleClient(agent_id="agent-1", session_id="session-1")
print(client.query({"query_text": "sanity check"}))

Error Handling

Non-2xx responses raise APIError:

from stele import APIError

try:
    client.reindex({})
except APIError as exc:
    print("status:", exc.status_code, "code:", exc.code, "request:", exc.request_id, "msg:", exc.message)

Graph Example: Add Edge + List

import time

client.edge_add(
    {
        "edge": {
            "from_id": "mem-aaa",
            "to_id": "mem-bbb",
            "type": "EDGE_TYPE_RELATES_TO",
            "weight": 1,
            "created_at_ms": int(time.time() * 1000),
        }
    }
)

edges = client.edge_list({"node_id": "mem-aaa"})
print(edges.get("edges"))

Proactive Surfacing Helper

Use the built-in trigger orchestrator when you want SDK-side proactive suggest parity:

suggestor = client.create_proactive_suggestor()
suggestor.trigger("bootstrap", {"active_files": ["README.md"]})
suggestor.trigger(
    "context_shift",
    {"active_files": ["src/auth/handler.go"], "recent_commands": ["plan:implement"]},
)
suggestor.trigger("pre_edit", {"active_symbols": ["AuthHandler"]})

ProactiveSuggestor enforces debounce, context-hash dedupe, rate limits, and payload caps before calling suggest.

Ops Endpoints (Bearer Token)

Ops endpoints require ops_auth_token (or env STELE_OPS_AUTH_TOKEN / STELE_MCP_AUTH_TOKEN):

• bulk_forget
• export_ndjson / export_to_file
• import_memories
• maintenance
• reindex
• decay

Export to File (Convenience)

import os
from stele import SteleClient

ops = SteleClient(
    base_url="http://127.0.0.1:8080",
    agent_id="agent-1",
    session_id="session-1",
    ops_auth_token=os.environ.get("STELE_OPS_AUTH_TOKEN", ""),
)
ops.export_to_file("stele-export.jsonl")

Import

from stele import SteleClient

with open("stele-export.jsonl", "r", encoding="utf-8") as f:
    ndjson = f.read()

ops.import_memories({"data": ndjson, "strict": False})

API Coverage (Method Map)

Methods map closely to steled routes:

• Core: write, query, feedback, protect, supersede, forget
• Retrieval utils: list_memories, get_memory, search_memories, update_memory, verify, extract
• Bulk: bulk_write, bulk_forget (ops)
• Ops: export_ndjson/export_to_file, import_memories, schema, metrics, maintenance, reindex, decay
• Graph: edge_add, edge_delete, edge_list, edge_traverse, edge_suggest
• Proactive/stream: suggest, watch
• Sharing: learn_share (mistake-only)
• Agent/system: agent_get, agent_upsert, access_mark_used, events, membership_add/remove/list, health, stats
