* fix: harden Discord bot against gateway disconnects and SSE failures - Isolate Discord API failures from SSE stream — _on_ws_event exceptions no longer kill the SSE connection and cause missed events - Fix broken exponential backoff on 4xx/5xx (delay was reset on every attempt); skip aiter_sse() on error responses - Add read timeout (90s) to SSE httpx client so half-open TCP connections are detected and recovered - Re-resolve node URL on each SSE reconnect attempt - Add on_resumed handler to recover SSE tasks that died during brief gateway disconnects (on_ready is not called on session resume) - Sync slash commands only on first on_ready to avoid Discord rate limits * fix: SSE backoff on 4xx/5xx and retrieve dead task exceptions - Replace `continue` with raise+catch so 4xx/5xx errors hit the exponential backoff path instead of tight-looping - Retrieve task exceptions in _purge_dead_sse_tasks to suppress "Task exception was never retrieved" warnings and log the cause
Turnstone
Multi-node AI orchestration platform. Deploy tool-using AI agents across a cluster of servers with direct HTTP routing, interactive interfaces, and enterprise governance.
Beta — Use at your own risk. APIs, configuration formats, and database schemas may change between versions without migration paths.
Named after the Ruddy Turnstone (Arenaria interpres) — a shorebird that flips stones to discover what's hiding underneath.
What it does
Turnstone gives LLMs tools — shell, files, search, web, planning — and orchestrates multi-turn conversations where the model investigates, acts, and reports.
- Interactive sessions — terminal CLI or browser UI with parallel workstreams
- Cluster dashboard — real-time view of all nodes and workstreams with console routing proxy
- Intent validation — LLM judge evaluates every tool call with risk assessments and evidence
- Governance — RBAC, OIDC SSO, tool policies, skills, usage tracking, audit logs
- Multi-provider — OpenAI-compatible APIs (vLLM, llama.cpp, NIM) and Anthropic Messages API
- MCP support — external tool servers with native deferred loading (Anthropic/OpenAI) or BM25 fallback
Quickstart
pip install turnstone
# Terminal REPL
turnstone --base-url http://localhost:8000/v1
# Browser UI
turnstone-server --port 8080 --base-url http://localhost:8000/v1
# Cluster dashboard
pip install turnstone[console]
turnstone-console --port 8090
Docker
cp .env.example .env # edit LLM_BASE_URL, OPENAI_API_KEY, etc.
docker compose --profile production up
See QUICKSTART.md for the bootstrap wizard and docs/docker.md for Docker configuration and profiles.
Programmatic (SDK)
from turnstone.sdk import TurnstoneServer
with TurnstoneServer("http://localhost:8080", token="tok_xxx") as client:
ws = client.create_workstream(name="demo")
result = client.send_and_wait("Analyze the error logs", ws.ws_id, auto_approve=True)
print(result.content)
Tools
Built-in tools for shell, files, search, web, memory, notifications, and autonomous sub-agents — plus external tools via MCP with native deferred loading. See docs/tools.md for the full reference and docs/mcp.md for MCP configuration.
Architecture
Single-node: Client → Server (direct HTTP + SSE). No external dependencies beyond the database.
Multi-node: Client → Console (hash ring routing proxy) → Server nodes. The console maintains a 65536-entry bucket cache for O(1) workstream routing. A rebalancer daemon redistributes buckets when nodes join or leave.
