Production-grade multimodal content analysis: explicit analysis pipeline (modality → decode → segment → extract → verify → report), evidence and provenance rules (page, time, region anchors), grounded vs inferred claims, failure modes (OCR error, sampling gaps, chart number invention, deepfakes, token limits, locked files), decision trade-offs (summary vs extract vs compare, full read vs stratified sample, human-in-the-loop for high-stakes), quality and anti-hallucination guardrails, structured reports with limitations and confidence — for documents, images, video, and audio. Not a replacement for legal, medical, or forensic experts. Use when the user supplies or points to content to summarize, extract, compare, or audit with traceable evidence. Combine with business-analysis-pro for BRD-style outputs, security-pro for PII/secrets, data-analysis-pro for tabular math on extracted data, web-research-pro for external fact-check, image-processing-pro for raster prep, testing-pro for extraction-regression tests.
System skill for automatic request analysis, prompt optimization, and intelligent routing to skills, workflows, or templates. Instead of calling skills individually, this skill analyzes user input, researches and improves the prompt for clarity and accuracy, identifies relevant skills, workflows, or templates, and coordinates execution. Use this skill when the user provides a general request that needs automatic decomposition, when the prompt needs optimization for better AI understanding, when appropriate skills or workflows need to be identified and executed, or when a template is needed for reports, issues, or other structured outputs. This is a **system skill** - it does not perform domain-specific work but routes to and coordinates **working skills** (chosen using **stack context** — see Stack context resolution; e.g. flutter-pro vs react-pro), **workflows** (/ticket, /debug, /release, etc.), and **templates** (reports, issues, prompts, etc.). Triggers: "route", "analyze", "plan", "break down", "how s

Expert-level orchestration of decentralized applications (dApps) and smart contracts. Focuses on the Ethereum ecosystem, security, and Web3 integration.
blockchain-pro covers Smart Contract development (Solidity), dApp frontend integration (ethers.js, viem), L2 scaling (Arbitrum, Optimism), and Security auditing. It does NOT cover building new L1 protocols or general cryptography theory.
