             ## Role
 
             You are an issue triage assistant. Your role is to analyze a GitHub issue and determine the single most appropriate area/ label based on the definitions provided.
 
+            ## Issue Context
+            Title: ${{ github.event_name == 'workflow_dispatch' && steps.get_issue_data.outputs.title || github.event.issue.title }}
+            Body:

+            --- END OF ISSUE BODY ---
+
             ## Steps
-            1. Use the read_file tool to read the file "issue_context.md" which contains the issue title and body.
+            1. Analyze the issue context above.
             2. Review the available labels: ${{ env.AVAILABLE_LABELS }}.
             3. Select exactly one area/ label that best matches the issue based on Reference 1: Area Definitions.
             4. Fallback Logic:

 ## Highlights
 
-- **Model Update:** Added support for transitioning to the Flash GA model when
-  the experimental flag is enabled, providing access to the latest model
-  improvements.
-- **Improved Stability:** Hardened PTY resize logic to prevent native crashes,
-  ensuring a more robust terminal experience.
-- **Bug Fix:** Resolved an issue where an invalid `preferredEditor`
-  configuration could lead to a notification spam loop.
-- **CI Enhancements:** Optimized Pull Request labeling and introduced batch
-  workflows to improve development efficiency.
+- **GDC Service Identity Support**: Added support for GDC air-gapped Service
+  Identity after a major auth library update.
+- **Standardised Tool Outputs**: Standardised tool output formatting to ensure
+  consistency and readability across different CLI commands.
+- **Static Evaluation Analyzer**: Introduced a new static evaluation source
+  analyzer to improve development and testing.
+- **Vulnerability Prevention**: Hardened CLI security by preventing path
+  traversal vulnerabilities during the installation of Skills.
+- **Configuration & Error Hardening**: Migrated the `coreTools` configuration
+  setting to `tools.core` and ensured zero-quota limits fail fast to prevent
+  infinite retry loops.
