Category of the diagnostic message.
Indicates the severity and type of the compilation issue, enabling AI agents to prioritize fixes and understand the impact of each diagnostic. Errors must be resolved for successful compilation, while warnings and suggestions can guide code quality improvements.
TypeScript diagnostic code for the specific issue.
Provides the official TypeScript diagnostic code that identifies the specific type of compilation issue. This code can be used to look up detailed explanations and resolution strategies in TypeScript documentation or automated correction systems.
Source file where the diagnostic was generated.
Specifies the TypeScript source file that contains the issue, or null if the diagnostic applies to the overall compilation process rather than a specific file. This information helps AI agents target corrections to the appropriate source files during the refinement process.
Length of the text span covered by this diagnostic.
Indicates how many characters from the start position are affected by this diagnostic, or undefined if the diagnostic doesn't apply to a specific text span. This information helps AI agents understand the scope of corrections needed for each issue.
Human-readable description of the compilation issue.
Provides a detailed explanation of the compilation problem in natural language that AI agents can analyze to understand the issue and formulate appropriate corrections. The message text includes context and suggestions for resolving the identified problem.
Character position where the diagnostic begins in the source file.
Specifies the exact location in the source file where the issue starts, or undefined if the diagnostic doesn't apply to a specific location. This precision enables AI agents to make targeted corrections without affecting unrelated code sections.
Detailed diagnostic information for compilation issues.
Provides comprehensive details about specific compilation problems including file locations, error categories, diagnostic codes, and descriptive messages. This information is essential for AI agents to understand compilation failures and implement precise corrections during the iterative development process.
