OpenCode LLM Provider Implementation Plan

Nicholai reviewed and approved a comprehensive plan to add OpenCode as a third extraction LLM provider for the Signet memory pipeline. Previously, only Ollama (HTTP API) and Claude Code (CLI subprocess) were available.

Design Overview

OpenCode v1.2.15 (installed at /home/nicholai/.opencode/bin/opencode) can run as a headless HTTP server and access any model it supports (Anthropic, Google, OpenAI, OpenRouter, local Ollama) through a unified REST API. The implementation will auto-start the OpenCode server on port 4096 when the daemon initializes, with automatic fallback to Ollama if unavailable.

Implementation Scope

Four files require modification:

packages/core/src/types.ts — add "opencode" to provider union
packages/daemon/src/pipeline/provider.ts — create createOpenCodeProvider() factory
packages/daemon/src/daemon.ts — wire provider selection and fallback logic
packages/daemon/src/memory-config.ts — recognize opencode in config resolution

Key Technical Decisions

Default model: anthropic/claude-haiku-4-5-20251001
Default timeout: 60s
Server management: daemon will spawn opencode serve --port 4096 as a child process, tracking it for cleanup on shutdown
Session reuse: single session created on first call, reused for all subsequent calls
Response handling: SSE (server-sent events) collected from /sessions/{id}/message endpoint until completion

Next Steps

Implementation work scheduled. First task: start OpenCode server and inspect actual response format at /doc endpoint to confirm SSE parsing approach.
