loomcycle 1.0 is here. Substrate complete. What's next.

Loomcycle 1.0, a feature-complete agentic runtime, is now available under Apache-2.0 license. The Go-based binary supports six LLM providers, 19 built-in tools, multi-replica high availability, and pause/snapshot/resume capabilities, validated by an 8-hour stability soak with 1.27 million circuits and 3.8 million agent runs. The release marks the completion of the substrate, with future plans focusing on plugins and integrations.

Two months from a JobEmber.ai VPS that ran out of memory at 3-5 parallel claude-print agents to a feature-complete agentic runtime. v1.0 ships today. Apache-2.0, one ~50 MB Go binary. The substrate is done: six LLM providers plus a deterministic code-js provider, 19 built-in tools with Claude Code parity, MCP on both sides, A2A on both sides, multi-replica HA on Postgres LISTEN/NOTIFY no Redis dep , pause/snapshot/resume even mid-run and across instances RFC X both phases , per-run credentials never reach the agent's view of its credentials map, a redact plugin in the run-loop that scrubs secrets before the model sees them, scheduled autonomous runs, signed inbound webhooks, content-addressed forkable AgentDefs with lineage. Production-grade validation: 8-hour stability soak 1.27M circuits, 3.8M agent runs, 100% completion across 468 waves, zero leaks plus a 133-minute autonomous run on local Qwen3.6:27b through ollama-local after the v0.34.3 to v0.37.0 robustness pass. Seven reproducible experiments in the repo exp1 to exp7 . Paca integration confirmed: direct agreement with the Paca maintainer Apache-2.0 AI-native Scrum / Trello / ClickUp alternative, 954 stars . The Paca maintainer is implementing the integration over gRPC - Paca's agent service calls loomcycle's gRPC surface directly to spawn runs, stream events, and route per-task agent credentials. Post-v1.0 plans: the context-compress plugin RFC Z Phase 2, LLMLingua-style ; SQL Memory RFC AA, per-scope SQL databases the runtime hosts for sandboxed agents ; capability-based memory interface with mem0 as the first MemoryLayer backend RFC K . Companion projects 4 : loomcycle, n8n-nodes-loomcycle, claude-code-plugin-loomcycle, and the Paca integration in flight. v1.0 is the first portable, durable, hardened version of the substrate. Everything from here is composition.
