Routing guide for Cherry Studio's first-party MCP tools: knowledge bases, memory, schedules, sessions, skills, MCP servers, web search, and bundled bun/uv/rg runtimes. Read it before attempting shell workarounds.

Guides reviewing GitHub SpecKit updates on Windows 11 with PowerShell while preserving local templates and customizations.

Authorized security assessment of PostgreSQL, MySQL, MSSQL, MongoDB, and Redis: exposure and TLS review, account role and grantee analysis, dangerous configuration checks (file_priv, xp_cmdshell, COPY PROGRAM, UDF), NoSQL injection, and audit log posture.

Offensive security skill for hunting insecure deserialization flaws in Java, PHP, Python, .NET and Ruby. Covers ysoserial gadget chains, PHP object injection, pickle payloads, ViewState and JNDI/Log4Shell, with strict authorization gates.

Automate binary reverse engineering with IDA Pro using MCP. Includes decompilation, disassembly, data-flow tracking, and cross-references. Features PowerShell scripts for server management and file handling to bypass schema validation and permission issues. Supports PE/ELF/Mach-O targets.

`jq` is the standard and powerful CLI tool for querying, filtering, and reshaping JSON data. This skill provides expert-level practical patterns for working with deeply nested structures, handling complex transformations (like flattening, renaming, and grouping), and integrating JSON logic into shell pipelines. Essential for parsing API outputs (AWS, GitHub), log files, and building robust Bash scripts.

This skill provides production-ready shell script templates for common Linux system administration tasks such as backups, monitoring, user management, and log analysis. It serves as a foundation for security operations and penetration testing environments, requiring basic bash knowledge and appropriate system permissions.

A comprehensive workflow bundle designed for system administrators and developers. It guides users through the entire lifecycle of system management and shell scripting across Linux, macOS, and Windows. Key phases include environment assessment, writing robust Bash scripts, advanced debugging techniques, linting with ShellCheck, and rigorous test automation using Bats, ensuring scalable and reliable automation.

This skill provides expertise in writing strict POSIX-compliant shell scripts for maximum portability across Unix-like systems. It focuses on shell-agnostic scripting compatible with dash, ash, sh, and bash in POSIX mode. Key areas include defensive programming, portable error handling, safe argument parsing, and cross-platform compatibility. It ensures scripts run on Linux, BSD, Solaris, AIX, and macOS without relying on GNU-specific features or bash extensions.

This skill generates Newman CLI commands, configuration files, Jenkins pipeline scripts, and shell automation for running Postman collections in CI/CD or local environments. It helps automate API testing workflows by creating reusable scripts and pipeline configurations that integrate seamlessly with development and deployment processes, ensuring consistent test execution.

This skill covers critical PowerShell Windows patterns including operator syntax rules, null checks, error handling, and file path management. It emphasizes avoiding common pitfalls like missing parentheses, Unicode characters, and type mismatches to ensure robust script execution.
