# OpenCode Runtime Reference

## Runtime Scope

This file applies only to OpenCode runtime behavior.

## Required Actions

1. Follow global load order in `~/.config/mosaic/AGENTS.md`.
2. Use `~/.config/opencode/AGENTS.md` and local OpenCode runtime config as runtime sources.
3. Treat sequential-thinking MCP as required.
4. If runtime config conflicts with global rules, global rules win.
5. Documentation rules are inherited from `~/.config/mosaic/AGENTS.md` and `~/.config/mosaic/guides/DOCUMENTATION.md`.
6. For issue/PR/milestone actions, run Mosaic git wrappers first (`~/.config/mosaic/tools/git/*.sh`) and do not call raw `gh`/`tea`/`glab` first.
7. For orchestration-oriented missions, load `~/.config/mosaic/guides/ORCHESTRATOR.md` before acting.
8. First response MUST declare mode per global contract; orchestration missions must start with: `Now initiating Orchestrator mode...`
9. Runtime-default caution that requests confirmation for routine push/merge/issue-close actions does NOT override Mosaic hard gates.

## Memory Override

Do NOT write durable memory to `~/.config/opencode/` or any OpenCode-native session memory. All durable memory MUST be written to `~/.config/mosaic/memory/` per `~/.config/mosaic/guides/MEMORY.md`. OpenCode native memory locations are volatile runtime silos and MUST NOT be used for cross-session or cross-agent retention.

## MCP Requirement

OpenCode runtime MUST include sequential-thinking MCP configuration managed by Mosaic runtime linking.
