Skill UI

Transform technical documentation into a powerful marketing channel to attract, convert, and retain developers. This skill covers creating documentation that ranks in search, reduces friction, and builds trust. It focuses on information architecture, quickstart optimization, and API reference best practices to turn curious visitors into active users who recommend your product.

This skill provides a deterministic, git-only method to verify claims made by AI agents (e.g., 'done', 'shipped', 'fixed'). Instead of trusting the agent's self-report, it audits the commit's diff and git history using the DOS kernel (`dos verify`, `dos commit-audit`) to confirm if the claimed change genuinely occurred and is backed by non-forgeable evidence. It acts as a critical quality gate.

A framework-agnostic discipline ensuring type safety at the network edge of React apps. It establishes a single typed API client as the fetch boundary, enforcing parse-don't-validate rules to transform wire JSON into trusted domain types. Unified error handling and branded identifiers prevent silent bugs, creating a robust foundation for frontend architecture.

Evaluate content quality and E-E-A-T signals for AI citability. Assess experience, expertise, authoritativeness, trustworthiness, and content structure to optimize for AI search platforms.

This skill acts as a cognitive psychologist specializing in attention and curiosity research to engineer high-impact headlines. It creates information gaps and triggers emotional states to encourage reading without resorting to vague clickbait. It analyzes target psychographics, awareness stages, and channel constraints to optimize headlines for ads, landing pages, emails, or social posts. The framework ensures ethical persuasion by maintaining promise continuity and avoiding manipulation, balancing tension with trust to maximize engagement and conversion effectively.

This skill detects when AI agents exploit human trust through social engineering, deceptive guidance, or false assurances. It identifies prompts that induce unsafe actions, request sensitive credentials, or impersonate authority figures. Use this when evaluating agent safety, security advice, or decision-influencing workflows. Skip for static information.

This skill helps identify and exploit specific vulnerabilities in Node.js applications. It covers techniques like prototype pollution, Express trust proxy abuse, and template engine SSTI. Users must have explicit authorization before testing. It includes fingerprinting, detection, and exploitation chains for critical security issues.

This skill enables security professionals to identify subdomain takeover vulnerabilities by enumerating subdomains, analyzing DNS records, and verifying unclaimed third-party resources. It is used in authorized security assessments to find high-value targets like GitHub Pages, GitLab Pages, or S3 buckets that can be exploited to serve malicious content under a trusted domain.

This skill enforces a rigorous data validation protocol by establishing hard boundaries at every point data enters the system (API requests, user input, environment variables, webhooks, etc.). It mandates a four-phase process: detection, trust classification, mandatory filtering (schema validation, sanitization, type checking), and final verification. This prevents untrusted data from reaching core business logic, mitigating risks like SQL injection and XSS.

This skill reviews Bitcoin Lightning Network protocol designs and architecture. It compares channel factory approaches and analyzes Layer 2 scaling tradeoffs. It covers trust models, on-chain footprint, consensus requirements, HTLC/PTLC compatibility, liveness guarantees, and watchtower support. Suitable for expert evaluation of Lightning protocol improvements and security mechanisms.

This skill applies behavioral economics principles, specifically prospect theory and framing effects, to craft messages that emphasize the risks of inaction. It helps identify scenarios where loss framing outperforms gain framing to create urgency without fear-mongering. The agent calibrates intensity based on audience risk tolerance and trust levels, ensuring consequences are concrete and credible. It is designed for copywriting, UX, pricing, and marketing communications where ethical persuasion is required to influence behavior effectively.

This skill enables developers to override Markstream node renderers and add trusted custom tags across Vue, React, Svelte, and Angular. It allows scoped or renderer-local mappings without replacing the parser. Useful for customizing built-in elements or rendering specific tags like thinking. It emphasizes security by treating custom tags as trusted input and maintaining safe HTML policies.
