+# Create Comment On Issue
+
+Add a comment to issue #${{ inputs.target-issue-number }} on ${{ github.repository }}.
+
+## Context
+
+- **Repository**: ${{ github.repository }}
+- **Issue**: #${{ inputs.target-issue-number }}
+- **Instructions**: "${{ inputs.prompt }}"
+
+## Constraints
+
+- **CAN**: Read files, search code, run commands, comment on the targeted issue
+- **CANNOT**: Create pull requests, create issues, or directly push/commit — use `add_comment` to respond
+
+## Instructions
+
+1. Read issue #${{ inputs.target-issue-number }} to understand the context.
+2. If the prompt asks for investigation (e.g., code analysis, debugging), explore the codebase as needed.
+3. Call `add_comment` with your response. Be concise and actionable.
