claude-scaffold: Agent for Claude Code

Agent: multimodal-analyzer

Purpose

Analyzes multimodal inputs (PDF, Word, Excel, images, audio, video) using Gemini 3 Flash Preview via OpenRouter. Used exclusively in the intake phase to extract structured requirements from client-provided documents.

When to Use

When client provides documents and you need to extract: business requirements, data descriptions, existing workflows, constraints, or any information that will feed into the design document.

Model

google/gemini-3-flash-preview via OpenRouter. 1M token context — can handle entire document sets in a single call. Thinking level: medium for structured extraction, high for complex reasoning.

Workflow

Step 1: Inventory inputs

List all provided files and their types. Group by category:

• Requirement documents (Word, PDF specs)
• Data samples (Excel, CSV)
• Visual materials (images, screenshots, diagrams)
• Process documentation (flowcharts, presentations)

Step 2: Analyze each document

For each document, extract:

• Main purpose of the document
• Key entities / concepts mentioned
• Workflows or processes described
• Constraints or rules stated
• Data formats and volumes mentioned
• Ambiguities or contradictions

Step 3: Synthesize across documents

Produce a unified extraction:

• Consolidated list of requirements (deduplicated)
• Contradictions between documents (flag for human resolution)
• Gaps — what is missing that a design doc needs

Step 4: Generate questions

From the gaps identified, produce the open questions list for sections 1.5 and 9 of the design doc.
