A comprehensive guide for developers implementing robust data persistence and file handling within Obsidian plugins. It covers best practices for saving plugin configurations, reliable vault file I/O (read, write, append), safe manipulation of YAML frontmatter via metadata cache, and registering event listeners for file renames and deletions. Essential for building stable, data-intensive plugins.

An expert guide for performing complex data analysis, cleaning, and transformation using pandas DataFrames. This skill covers advanced techniques such as vectorized operations, efficient merging, time series resampling, group-by aggregations, and memory optimization, ensuring production-grade code and robust data validation.

Biopython provides Python APIs for sequence manipulation, database access, BLAST automation, structural bioinformatics, and phylogenetics, making it ideal for scripting custom pipelines and batch processing in computational molecular biology workflows.

This guide provides a quick reference for 'pipe' and 'flow' utilities in fp-ts. The `pipe` function is used to chain multiple operations to transform a specific value, while `flow` allows you to create reusable, composed functions (pipelines). It is essential for implementing clean, declarative data manipulation and functional composition in TypeScript.

Master the creation and manipulation of 3D geometry within the Three.js framework. This guide covers built-in primitive shapes (Box, Sphere, Cylinder), advanced procedural geometries (Extrude, Tube, TorusKnot), and text visualization. Crucially, it details the use of BufferGeometry, allowing developers to store vertex, normal, UV, and color data in optimized typed arrays for high-performance rendering and custom mesh construction.

Guide for performing Android and iOS mobile application penetration testing with OWASP MASTG/MASVS, covering static/dynamic analysis, data storage checks, API abuse, and runtime manipulation using Frida, Objection, and MobSF.

A specialized Python detector designed to monitor Operational Technology (OT) historian servers (such as OSIsoft PI, Ignition, etc.). It identifies critical indicators of compromise (IOCs), including unauthorized network connections, data manipulation attempts, and lateral movement activities that bridge IT and OT zones. Use this skill when validating data integrity and investigating potential cyber breaches in industrial environments.

This skill provides methods and tools for detecting sophisticated cyber attacks targeting Supervisory Control and Data Acquisition (SCADA) and Industrial Control Systems (ICS). It focuses on detecting anomalies like unauthorized command injection, Man-in-the-Middle attacks on industrial protocols (Modbus, DNP3), and data manipulation, which traditional IT security tools often miss. Usage involves establishing deterministic communication baselines and monitoring network traffic for deviations.

This script automates the testing of API endpoints for mass assignment (over-posting) vulnerabilities, adhering to OWASP API3:2023 guidelines. It systematically injects undocumented, privileged fields (like 'role', 'isAdmin', 'balance', 'price') into request bodies of typical endpoints (e.g., profile updates, order creation). It checks if the server binds these unexpected fields to the data model without proper filtering, potentially allowing unauthorized privilege escalation or data manipulation.

PDFtk Server is a powerful command-line tool designed for comprehensive manipulation and processing of PDF documents. It allows users to programmatically merge, split, rotate, secure (encrypt/decrypt), fill forms, apply watermarks, extract metadata, repair corrupted files, and much more. Ideal for automation scripts, batch processing, and any scenario requiring robust, scripted PDF handling from the terminal.

Process and resize images using ImageMagick across Windows, Linux, and macOS, including metadata inspection, format conversion, thumbnail creation, and batch workflows for wallpapers or mass photo adjustments.

Anndata is a Python package for handling annotated data matrices, storing experimental measurements alongside observation and variable metadata. It supports single-cell genomics analysis, managing h5ad and Zarr files efficiently. Users can read, write, concatenate, and subset data with sparse matrix support. It integrates with the scverse ecosystem including Scanpy and scvi-tools. Ideal for biological data workflows requiring efficient storage and manipulation.
