Customer-centric conversion rate optimization methodology based on "Making Websites Win" by Karl Blanks and Ben Jesson (Conversion Rate Experts). Use when optimizing websites, landing pages, funnels, improving conversion rates, analyzing why visitors don't convert, creating persuasive copy, designing A/B tests, auditing UX, or building customer-centric websites. Provides systematic CRO process, objection/counter-objection framework, and evidence-based optimization techniques.
Configure Qdrant vector database for GrepAI. Use this skill for high-performance vector search.
Lead generation system using quiz/assessment funnels (Scorecard Marketing). Use when creating landing pages for lead generation, quiz funnels, online assessments, questionnaires that qualify leads, or any "lead magnet" that collects data while providing value. Based on Daniel Priestley's methodology that converts 30-50% vs 3-10% for traditional PDF lead magnets.
Guides the creation of self-signed SSL/TLS certificates using OpenSSL, including key generation, certificate creation, combined PEM files, and verification scripts. This skill should be used when tasks involve generating self-signed certificates, creating SSL certificate infrastructure, or writing certificate verification scripts.
Guide for setting up local PyPI servers to host and serve Python packages. This skill should be used when tasks involve creating a local PyPI repository, serving Python packages over HTTP, building distributable Python packages, or testing pip installations from a custom index URL.
Search messages, read threads, and send messages in Slack. Use when looking up discussions, finding context about a topic, or sending notifications to channels.
Guide for recovering lost Git commits, resolving detached HEAD states, and fixing common Git repository issues. This skill should be used when users need help recovering from Git mistakes such as lost commits, detached HEAD situations, accidental resets, or when commits appear to be missing from branches.
Guidance for bypassing HTML/JavaScript sanitization filters in security testing contexts. This skill should be used when tasked with finding XSS filter bypasses, testing HTML sanitizers, or exploiting parser differentials between server-side filters and browsers. Applies to CTF challenges, authorized penetration testing, and security research involving HTML injection and JavaScript execution through sanitization bypasses.
Guidance for counting tokens in datasets, particularly from HuggingFace or similar sources.

Triggers on requests for font selection, readable text, typographic hierarchy, font pairing, or "making text look better."
Guidance for implementing high-performance portfolio optimization using Python C extensions. This skill applies when tasks require optimizing financial computations (matrix operations, covariance calculations, portfolio risk metrics) by implementing C extensions for Python. Use when performance speedup requirements exist (e.g., 1.2x or greater) and the task involves numerical computations on large datasets (thousands of assets).
