Values and Block Bodies¶

PromptScript preserves body entries in source order. Every built-in block has one canonical body shape.

Four Shapes¶

@meta { id: "body-shapes" syntax: "1.5.0" }

@identity {
  """
  You are a careful maintainer.
  """
}

@context {
  runtime: "Node.js 20+"

  """
  This service processes checkout requests.
  """
}

@standards {
  code: ["Use strict TypeScript", "Use named exports"]
}

@restrictions {
  - "Never expose secrets"
}

An array used as a property value does not make its parent block an array body. @standards above remains an object body.

Compatibility and PS038¶

Legacy forms remain parseable when current consumers have defined behavior. PS038 warns when a form can lose data or compile differently by target.

Common remediation:

@meta { id: "canonical-shortcut" syntax: "1.5.0" }

@shortcuts {
  "/review": {
    description: "Review current changes"
    content: """
      Review correctness, security, and tests.
    """
  }
}

Run strict validation before release:

prs validate --strict

See Block Shapes for the complete built-in matrix and merge behavior.
