To create a standardized prompt template, use a predefined .prompt.md file with YAML frontmatter containing a description, followed by structured sections like Title, Task Description, Steps, and a Default Behavior block to ensure agent clarity.

A Default Behavior block is a mandatory section within .prompt.md prompt templates that specifies fallback actions or constraints, ensuring AI agents execute tasks predictably even when explicit instructions are missing or ambiguous.

You can enforce a consistent prompt authoring workflow by referencing shared instruction rules in prompt-spec.md and utilizing a blank template in prompt-template.md, ensuring all .prompt.md files adhere to the same structural and frontmatter standards.

No dependencies are required to use the prompt-template authoring workflow; it operates self-contained using internal references and blank template assets to generate standardized .prompt.md files without external packages.

A .prompt.md file requires YAML frontmatter with a description, followed by anchored sections including Title, Task Description, Steps, and a Default Behavior block to maintain structural consistency and provide clear agent instructions.

AI agents may fail to follow prompt instructions if the .prompt.md file lacks a mandatory Default Behavior block or structured sections, which are required to provide well-defined constraints and predictable execution paths.
