+Ground evidence using `gh issue view {{issue_number}} --json number,title,body,author,createdAt,updatedAt,state,labels,milestone,reactions,comments,linkedPullRequests`, download images via MCP `github_issue_images` to better understand the issue context. Finally, use MCP `github_issue_attachments` to download logs with parameter `extractFolder` as `Generated Files/issueReview/{{issue_number}}/logs`, and analyze the downloaded logs if available to identify relevant issues. Locate the source code in the current workspace (use `rg`/`git grep` as needed). Link related issues and PRs.
+
+## When to call MCP tools
+If the following MCP "github-artifacts" tools are available in the environment, use them:
+- `github_issue_images`: use when the issue/PR likely contains screenshots or other visual evidence (UI bugs, glitches, design problems).
+- `github_issue_attachments`: use when the issue/PR mentions attached ZIPs (PowerToysReport_*.zip, logs.zip, debug.zip) or asks to analyze logs/diagnostics. Always provide `extractFolder` as `Generated Files/issueReview/{{issue_number}}/logs`
+
+If these tools are not available (not listed by the runtime), start the MCP server "github-artifacts" first.
