+# Example Fleet Goal
+
+Analyze the codebase for potential improvements and create
+issues for the engineering team.
+
+## Tools
+- Test Coverage: `npx vitest --coverage --json`
+
+## Assessment Hints
+- Focus on missing error handling in API routes
+- Look for hardcoded configuration values
+
+## Insight Hints
+- Report on overall test coverage metrics
+- Note any unusually complex functions (cyclomatic complexity)
+
+## Constraints
+- Do NOT propose changes already covered by open issues
+- Do NOT propose changes rejected in recently closed issues
+- Keep tasks small and isolated — one logical change per issue
