creating-spec
A workflow orchestrator that guides developers through feature specification from initial sizing assessment to task breakdown. It intelligently routes projects between simplified and full specification paths based on complexity criteria, then coordinates external tools for requirements, design, and task planning phases.
logging
Adds structured logging to Docker-based CFN Loop tasks by capturing container stdout/stderr, exit codes, Redis coordination events, and lifecycle events. Provides query tools and JSON export for debugging and compliance. Requires manual integration into existing shell scripts.
design-preferences
This skill guides users through a structured questionnaire to define visual preferences before UI development. It creates a DESIGN.md file with chosen themes, fonts, and motion settings, integrating with project planning phases. It skips detailed questions for MVP projects and references a theme library.
extensibility-advisor
Helps developers choose the right Claude Code extension method (Skills, Commands, Subagents, etc.) based on their use case. Provides clear decision criteria and trade-off explanations to avoid confusion when extending Claude's capabilities.
subagent-generator
Generates specialized Claude Code subagents with appropriate tool restrictions, model selection, and system prompts. Creates properly formatted .md files with YAML frontmatter based on user's domain requirements. Guides users through purpose definition, tool recommendations, and prompt creation.
tmux
This skill enables Claude to remotely control tmux sessions for interactive command-line work. It provides detailed instructions for sending keystrokes, scraping pane output, and managing sessions via private sockets. Includes specific recipes for Python REPLs, gdb, and other TTY applications with synchronization helpers.
better-icons
Use when working with icons in any project. Provides CLI for searching 200+ icon libraries (Iconify) and retrieving SVGs. Commands: `better-icons search <query>` to find icons, `better-icons get <id>` to get SVG. Also available as MCP server for AI agents.
usgs-data-download
Download water level data from USGS using the dataretrieval package. Use when accessing real-time or historical streamflow data, downloading gage height or discharge measurements, or working with USGS station IDs.
ripgrep
Efficient text search using ripgrep (rg) with one-shot patterns that minimize iterations by getting files, line numbers, and context in a single call
ctf-rev
Solve CTF reverse engineering challenges using systematic analysis to find flags, keys, or passwords. Use for crackmes, binary bombs, key validators, obfuscated code, algorithm recovery, or any challenge requiring program comprehension to extract hidden information.
dotnet-backend
A .NET/C# backend development expert specializing in building enterprise-grade ASP.NET Core APIs, including REST, minimal APIs, and gRPC services, with features like Entity Framework Core, authentication/authorization, background services, and real-time SignalR for robust and scalable solutions.
translator
This skill provides zero-cost, LLM-native translation for SpecWeave content, leveraging the current conversation's model to translate CLI messages, templates, and documentation while preserving formatting and key technical terms.
cfn-automatic-memory-persistence
Automatically saves Claude agent outputs to a SQLite database with structured schema. Provides query tools for retrieving past outputs by agent or task. Useful for tracking multi-iteration workflows and maintaining execution history.
secrets-guardian
Sets up pre-commit hooks with gitleaks and detect-secrets to prevent accidental secret commits. Provides setup commands, scanning workflows, and remediation steps for leaked credentials. Includes CI/CD integration and multilingual triggers.
state-transition
Enforces structured state transitions for development tasks with prerequisite validation. Prevents invalid state changes, tracks transition history, and integrates with a defined workflow. Returns clear JSON results showing success or specific missing requirements.
db-initializer
A database initialization skill that coordinates infrastructure provisioning and schema setup for new projects. It handles both local and cloud databases, validates configurations, and provides clear structured outputs with error recovery guidance.
infra-tester
This skill automates infrastructure testing by running security scans with Checkov/tfsec, estimating costs, and validating deployments. It handles both pre-deployment validation and post-deployment verification, generating detailed test reports and blocking deployments when critical issues are found.
mcp-development
Provides detailed guidance for building MCP servers with the latest 2025-11-25 specification, covering transport mechanisms, tool annotations, and production deployment patterns. Includes code examples for Python and TypeScript implementations.
portfolio-optimization
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).
basicmemory
This skill helps set up and manage a 'basicmemory' project for Claude, providing initialization checks and access to guide documents. It ensures a memory project exists and offers functions to list and read guide files. The implementation is straightforward but limited to a specific project structure.
