+- Current git status: !`git status`
+- Current git diff (staged and unstaged changes): !`git diff HEAD`
+- Current branch: !`git branch --show-current`
+
+## Your task
+
+Based on the above changes:
+1. Create a new branch if on main
+2. Create a single commit with an appropriate message
+3. Push the branch to origin
+4. Create a pull request using `gh pr create`
+5. You have the capability to call multiple tools in a single response. You MUST do all of the above in a single message. Do not use any other tools or do anything else. Do not send any other text or messages besides these tool calls.

+description: Find duplicate GitHub issues
+---
+
+Find up to 3 likely duplicate issues for a given GitHub issue.
+
+To do this, follow these steps precisely:
+
+1. Use an agent to check if the Github issue (a) is closed, (b) does not need to be deduped (eg. because it is broad product feedback without a specific solution, or positive feedback), or (c) already has a duplicates comment that you made earlier. If so, do not proceed.
+2. Use an agent to view a Github issue, and ask the agent to return a summary of the issue
+3. Then, launch 5 parallel agents to search Github for duplicates of this issue, using diverse keywords and search approaches, using the summary from #1
+4. Next, feed the results from #1 and #2 into another agent, so that it can filter out false positives, that are likely not actually duplicates of the original issue. If there are no duplicates remaining, do not proceed.
+5. Finally, comment back on the issue with a list of up to three duplicate issues (or zero, if there are no likely duplicates)
+
+Notes (be sure to tell this to your agents, too):
+
+- Use `gh` to interact with Github, rather than web fetch
+- Do not use other tools, beyond `gh` (eg. don't use other MCP servers, file edit, etc.)
+- Make a todo list first
+- For your comment, follow the following format precisely (assuming for this example that you found 3 suspected duplicates):
+
+---
+
+Found 3 possible duplicate issues:
+
+1. <link to issue>
+2. <link to issue>
+3. <link to issue>
+
+This issue will be automatically closed as a duplicate in 3 days.
+
+- If your issue is a duplicate, please close it and 👍 the existing issue instead
+- To prevent auto-closure, add a comment or 👎 this comment

+description: Triage GitHub issues and label critical ones for oncall
+---
+
+You're an oncall triage assistant for GitHub issues. Your task is to identify critical issues that require immediate oncall attention and apply the "oncall" label.
+
+Repository: OrcaSlicer/OrcaSlicer
+
+Task overview:
+
+1. First, get all open bugs updated in the last 3 days with at least 50 engagements:
+   ```bash
+   gh issue list --repo OrcaSlicer/OrcaSlicer --state open --label bug --limit 1000 --json number,title,updatedAt,comments,reactions | jq -r '.[] | select((.updatedAt >= (now - 259200 | strftime("%Y-%m-%dT%H:%M:%SZ"))) and ((.comments | length) + ([.reactions[].content] | length) >= 50)) | "\(.number)"'
+   ```
+
+2. Save the list of issue numbers and create a TODO list with ALL of them. This ensures you process every single one.
+
+3. For each issue in your TODO list:
+   - Use `gh issue view <number> --repo OrcaSlicer/OrcaSlicer --json title,body,labels,comments` to get full details
+   - Read and understand the full issue content and comments to determine actual user impact
+   - Evaluate: Is this truly blocking users from using Claude Code?
+     - Consider: "crash", "stuck", "frozen", "hang", "unresponsive", "cannot use", "blocked", "broken"
+     - Does it prevent core functionality? Can users work around it?
+   - Be conservative - only flag issues that truly prevent users from getting work done
+
+4. For issues that are truly blocking and don't already have the "oncall" label:
+   - Use `gh issue edit <number> --repo OrcaSlicer/OrcaSlicer --add-label "oncall"`
+   - Mark the issue as complete in your TODO list
+
+5. After processing all issues, provide a summary:
+   - List each issue number that received the "oncall" label
+   - Include the issue title and brief reason why it qualified
+   - If no issues qualified, state that clearly
+
+Important:
+- Process ALL issues in your TODO list systematically
+- Don't post any comments to issues
+- Only add the "oncall" label, never remove it
+- Use individual `gh issue view` commands instead of bash for loops to avoid approval prompts
