Screenshot Analyzer (Multi-Agent)

Extract product features from UI screenshots using a coordinated multi-agent analysis pipeline.

Core principle: Describe WHAT to build (features/interactions), NOT HOW (no tech stack).

Multi-Agent Architecture

This skill orchestrates 5 specialized agents for comprehensive analysis:

Process

Phase 1: Screenshot Collection

Gather all screenshots to analyze:

Read the screenshot file(s) provided by the user

For each screenshot, note the file path and any context provided

If multiple screenshots, determine if they are from the same product

Phase 2: Parallel Analysis

Launch THREE Task agents IN PARALLEL for each screenshot:

Agent 1: screenshot-ui-analyzer

Analyze this screenshot for UI components, layout structure, and design patterns.
Screenshot: [file path]
Return your analysis as JSON.

Agent 2: screenshot-interaction-analyzer

Analyze this screenshot for user interactions, navigation flows, and state transitions.
Screenshot: [file path]
Return your analysis as JSON.

Agent 3: screenshot-business-analyzer

Analyze this screenshot for business functions, data entities, and domain logic.
Screenshot: [file path]
Return your analysis as JSON.

IMPORTANT: Use the Task tool with THREE parallel calls in a single message to maximize efficiency.

Phase 3: Synthesis

After all parallel analyses complete, launch the synthesizer agent:

Agent 4: screenshot-synthesizer

Synthesize these analysis results into a unified development task list.

UI Analysis:
[paste UI analyzer result]

Interaction Analysis:
[paste Interaction analyzer result]

Business Analysis:
[paste Business analyzer result]

Product Name: [product name]
Output file: docs/plans/YYYY-MM-DD-<product>-features.md

Phase 4: Review

Launch the reviewer agent to validate the output:

Agent 5: screenshot-reviewer

Review this task list for completeness and quality.

Original screenshot(s): [file paths]
Task list: [synthesized output]

If issues found, provide corrections.

Phase 5: Output

Write final task list to docs/plans/YYYY-MM-DD-<product>-features.md

Use format from references/output-format.md

Present summary to user

Key Guidelines

Use - [ ] checkbox format for all tasks

Break features into small, executable subtasks

Focus on user interactions, not implementation details

For multiple screenshots: deduplicate features across all screens

For competitive analysis: highlight unique features and gaps

Benefits of Multi-Agent Approach

Thoroughness - Three specialized perspectives catch more details

Speed - Parallel analysis reduces total time

Quality - Synthesis + Review ensures coherent, complete output

Specialization - Each agent focuses on its domain expertise
