+# Smoke Test: OpenCode Custom Engine Validation
+
+**IMPORTANT: Keep all outputs extremely short and concise. Use single-line responses where possible. No verbose explanations.**
+
+## Test Requirements
+
+1. **GitHub MCP Testing**: Review the last 2 merged pull requests in ${{ github.repository }}
+2. **Serena Go Testing**: Use the `serena-go` tool to run a basic go command like "go version" to verify the tool is available
+3. **Playwright Testing**: Use playwright to navigate to https://github.com and verify the page title contains "GitHub"
+4. **File Writing Testing**: Create a test file `/tmp/gh-aw/agent/smoke-test-opencode-${{ github.run_id }}.txt` with content "Smoke test passed for OpenCode at $(date)" (create the directory if it doesn't exist)
+5. **Bash Tool Testing**: Execute bash commands to verify file creation was successful (use `cat` to read the file back)
+
+## Output
+
+1. **Create an issue** with a summary of the smoke test run:
+   - Title: "Smoke Test: OpenCode - ${{ github.run_id }}"
+   - Body should include:
+     - Test results (✅ or ❌ for each test)
+     - Overall status: PASS or FAIL
+     - Run URL: ${{ github.server_url }}/${{ github.repository }}/actions/runs/${{ github.run_id }}
+     - Timestamp
+
+2. Add a **very brief** comment (max 5-10 lines) to the current pull request with:
+   - PR titles only (no descriptions)
+   - ✅ or ❌ for each test result
+   - Overall status: PASS or FAIL
+
+If all tests pass, add the label `smoke-opencode` to the pull request.
