"Access UniProt for protein sequence and annotation retrieval. Use this skill when: (1) Looking up protein sequences by accession, (2) Finding functional annotations, (3) Getting domain boundaries, (4) Finding homologs and variants, (5) Cross-referencing to PDB structures.

two-stage review (spec compliance first, then code quality), refactoring, and quality improvement. Use when reviewing code, eliminating code smells, reducing technical debt, refactoring methods, running self-critique loops, or improving maintainability and readability.

Annotate ChIP-seq peaks to genomic features and genes using ChIPseeker. Assign peaks to promoters, exons, introns, and intergenic regions. Find nearest genes and calculate distance to TSS. Generate annotation plots and statistics. Use when annotating ChIP-seq peaks to genomic features.

Identify spatial domains and tissue regions in spatial transcriptomics data using Squidpy and Scanpy. Cluster spots considering both expression and spatial context to define anatomical regions. Use when identifying tissue domains or spatial regions.

Spawn an AI coding agent in a new terminal (Claude, Codex, Gemini, Cursor, OpenCode, Copilot). Defaults to Claude Code if unspecified.

This skill should be used when the user asks to "search for exposed devices on the internet," "perform Shodan reconnaissance," "find vulnerable services using Shodan," "scan IP ranges with Shodan," or "discover IoT devices and open ports." It provides comprehensive guidance for using Shodan's search engine, CLI, and API for penetration testing reconnaissance.

Optimize Next.js 15 applications for performance, Core Web Vitals, and production best practices using App Router patterns

Query and download from NCBI Gene Expression Omnibus (GEO) and EMBL-EBI's BioStudies/ArrayExpress mirror. Use when finding expression datasets, navigating SuperSeries vs SubSeries, choosing between series-matrix (submitter-normalized) and raw supplementary files, downloading via GEOparse (Python) or GEOquery (R/Bioconductor), linking GEO to SRA for raw reads, or distinguishing GSE/GSM/GPL/GDS reco

Converte URLs de tweets ou artigos do X (Twitter) para markdown. Utiliza uma API privada do X, obtida por engenharia reversa, e requer consentimento do usuário antes do uso.

Cria arte algorítmica com p5.js, usando aleatoriedade semeada e exploração interativa de parâmetros. Ideal para gerar arte com código, arte generativa, campos de fluxo ou sistemas de partículas, focando em criações originais.

Comprehensive Flow Nexus platform management - authentication, sandboxes, app deployment, payments, and challenges

Use when implementing data validation for API payloads, form inputs, or database writes. Triggers for: Pydantic models, Zod schemas, input sanitization, type validation, field constraints, or request/response schemas. NOT for: business logic (use domain services) or authentication/authorization.
