Content Extractor

Turn the requested subject and boundaries into a traceable content-selection plan.

• Inspect reusable transcripts and indexes before scheduling a search.
• Search for meaning and supporting visual evidence, not keywords alone.
• Preserve enough context for statements and demonstrations to remain understandable.
• Make ordering and overlap handling explicit before proposing the timeline.
• Keep the semantic target separate from duration, variant, subtitle, aspect-ratio, and delivery instructions. Those explicit deliverables are composed after content selection rather than mixed into the search query.
• A find-only request ends with evidence rather than creating an unrequested cut. For a combined cut, autonomous-review mode may select valid candidates and apply its timeline proposal without interrupting the user; stepwise-review mode requires candidate and timeline confirmation.
• Autonomous-review mode must finish with a low-resolution review preview. Stepwise-review mode prepares subtitles or a review preview only when requested. Never treat a preview as a formal export.
