OpenCode 2.0: one local service, Code Mode MCP, background subagents

At a glance

Anomaly OpenCode 2.0 (Oct 12; changelog still shipping 2.0.x Oct 16): auto-started local background service shared by TUI/web/desktop; rewritten API + @opencode/client; @opencode/codemode turns MCP/OpenAPI into scriptable functions (all MCP servers default to Code Mode); background subagents + async shell; 80+ hot-reload plugins; @opencode/sdk for embed. Upgrade: `opencode upgrade --major`. This workflow is listed under coding-agents, MCP, Code-Mode, orchestration, open-source.

Prompt excerpt

Upgrade with opencode upgrade --major, add several MCP servers, then ask OpenCode to compose them in one Code Mode script while a background subagent reviews the diff.

Claustrum: harness-neutral architect that delegates to any coding agent via MCP

Claustrum (alpha, .NET NativeAOT) is a harness-neutral conductor: an architect in Claude Code, Cursor, Copilot CLI, opencode, or desktop delegates builds/reviews/tests to agents on any other harness/model and gets one normalized JSON receipt. Two doors — `claustrum run` CLI and `claustrum mcp` stdio server. Parallel builders on git worktrees, budget ledger, backends doctor. Role-based routing (strong model for architect/reviewer, cheap for builders) without locking the pipeline to one vendor.

Kerno: local runtime QA that verifies agent changes against your stack

MCP-connected runtime QA maps critical flows and entry points, then re-tests the blast radius of each Claude Code/Cursor/Codex change against live Postgres/Kafka/APIs/MCP tools—contracts, authz, OWASP, errors—before merge, with self-heal when behavior changes on purpose.

MuscleMemory: test-gated procedural memory for coding agents

Open-source local procedural memory that learns only after tests pass, then hands Claude Code/Codex/Cursor a short verified skill note on similar tasks (reported token/tool cuts in published benchmarks).
