Review Details

Files:

• .changeset/hungry-lands-sin.md - Standard changeset file
• src/core/prompts/tools/native-tools/read_file.ts - Adds examples property to JSON Schema

Checked: Security, bugs, code quality, JSON Schema validity

Analysis:

• The examples property is a valid JSON Schema keyword that helps models understand expected input format
• The example correctly adapts based on partialReadsEnabled flag
• The conditional line_ranges: undefined will be omitted during JSON serialization, which is the correct behavior
• Code follows existing patterns in the codebase

Minor Note: When partialReadsEnabled is false, the example includes line_ranges: undefined. This works correctly because undefined properties are omitted during JSON serialization, but an alternative approach would be to conditionally include the property only when needed. This is a stylistic preference and not a bug.
