ADDED Requirements

Requirement: Agent Skill Media Model Selectors

The AI input bar SHALL show additional media model selectors when Agent mode has an explicitly selected Skill that is known to invoke media generation.

Scenario: Image or PPT Skill selected

• GIVEN the user is in Agent mode
• AND the selected Skill is classified as image or PPT output
• WHEN the input bar renders
• THEN it SHALL keep the text model selector for Agent analysis
• AND it SHALL show an image model selector for the Skill's media generation

Scenario: Video Skill selected

• GIVEN the user is in Agent mode
• AND the selected Skill is classified as video output
• WHEN the input bar renders
• THEN it SHALL keep the text model selector for Agent analysis
• AND it SHALL show a video model selector for the Skill's media generation

Scenario: Audio Skill selected

• GIVEN the user is in Agent mode
• AND the selected Skill is classified as audio output
• WHEN the input bar renders
• THEN it SHALL keep the text model selector for Agent analysis
• AND it SHALL show an audio model selector for the Skill's media generation

Scenario: Auto Skill selected

• GIVEN the user is in Agent mode
• AND the selected Skill is Auto
• WHEN the input bar renders
• THEN it SHALL NOT show additional media model selectors

Requirement: Agent Skill Media Model Routing

Agent and Skill workflows SHALL pass selected media model IDs and model references to downstream media generation tools.

Scenario: Dynamic media tool call

• GIVEN Agent analysis emits a media generation tool call without a model
• WHEN the execution context contains a selected model for that media type
• THEN the generated workflow step SHALL include that selected model
• AND it SHALL include the matching modelRef when available

Scenario: Parsed Skill workflow step

• GIVEN a Skill DSL resolves directly to a media generation workflow step
• WHEN the execution context contains a selected model for that media type
• THEN the workflow step SHALL use the selected media model
• AND it SHALL include the matching modelRef when available
