+### Requirement: Prompt Lineage History

+
+#### Scenario: New task has prompt metadata
+- **WHEN** a generation task is created from AI input
+- **THEN** the task stores lightweight prompt metadata with initial prompt, sent prompt, category, and optional Skill identifiers
+
+#### Scenario: Old task has no prompt metadata
+- **WHEN** an older task is shown in prompt history
+- **THEN** the initial prompt falls back to `sourcePrompt`, then `rawInput`, then `prompt`
+- **AND** the sent prompt falls back to `prompt`
+
+### Requirement: Prompt History Filtering
+The prompt history tool SHALL support filtering by image, video, audio, text, and Agent categories, with optional Skill tag filtering.
+
+#### Scenario: User filters prompt records
+- **WHEN** the user selects a category, Skill tag, or search query
+- **THEN** the tool shows only matching prompt history records in reverse chronological order
+
+### Requirement: Prompt Hover Details
+Prompt list items SHALL optionally show prompt titles in the list while keeping sent prompt as the selectable content.
