+# OpenCode
+
+## Goal
+
+Use this repository as the instruction pack for building n8n workflows conversationally through MCP.
+
+## Suggested setup
+
+- configure the n8n MCP server in OpenCode
+- provide `templates/system-prompt.md` as the primary behavior file
+- optionally pin `docs/skill-spec.md` for extra grounding
+
+## Good defaults
+
+For most users:
+- mode: balanced
+- assumptions: explicit
+- plan required before build: yes
+- final report: concise but complete
+
+See `config-snippets.md` for example `opencode mcp add` and `opencode.jsonc` setup.

+# OpenCode config snippets
+
+These snippets are examples. Replace placeholder URLs and names with your real n8n MCP configuration.
+
+## Guided setup
+
+```bash
+opencode mcp add
+opencode mcp list
+```
+
+## Example `opencode.jsonc`
+
+```jsonc
+{
+  "$schema": "https://opencode.ai/config.json",
+  "mcp": {
+    "n8n": {
+      "type": "remote",
+      "url": "https://YOUR-N8N-MCP-ENDPOINT",
+      "enabled": true
+    }
+  }
+}
+```
+
+## Suggested agent instruction
+
+```text
+When the task is about n8n workflows, use the n8n MCP server and follow the Vibeflow n8n repository contract. Produce a normalized plan first, then build, validate, and report.
