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.
graphql-api
Provides ready-to-use GraphQL API templates for Rust (async-graphql), Python (strawberry), and Node.js (Apollo). Includes schema design patterns, resolver examples, DataLoader implementations for N+1 prevention, and subscription setup. Mandates security pre-commit hooks before coding.
backend-rust
Provides a complete Rust backend template using Axum, SQLx, and tokio with automation scripts for building, testing, linting, and security auditing. Includes mandatory project protection setup, structured code examples, and deployment guidance for Shuttle.
testing-python
This skill provides detailed guidance for Python testing using pytest, covering unit tests, async tests, mocking, fixtures, and coverage. It includes practical examples, configuration templates, and best practices for structuring test suites. The skill helps developers write better tests with modern Python tooling.
roadmap
Manages project roadmaps through a structured markdown system that tracks ideas, research, completed features, and rejected proposals. Provides commands for adding items, creating specs, archiving work, and analyzing dependencies. Uses priority/effort ratings and maintains institutional memory.
agentdb-optimization
Provides concrete optimization techniques for AgentDB vector databases including quantization (4-32x memory reduction), HNSW indexing (150x faster search), caching strategies, and batch operations. Includes specific performance benchmarks and configuration examples for different use cases.
git-worktrees
This skill provides concrete workflows for managing git worktrees in issue-driven development. It offers specific commands for creating worktrees based on issue hierarchy, handling cleanup after PR merges, and maintaining worktree hygiene. The documentation includes real bash command examples and step-by-step scenarios.
brainwriting
A structured brainstorming tool that uses parallel sub-agents to explore and refine ideas through 5 rounds of analysis. It transforms vague concepts into practical expressions by applying different thinking perspectives systematically.
spec-driven
Guide spec-driven development workflow (Requirements → Design → Tasks → Implementation) with approval gates between phases. Use when user wants structured feature planning or says "use spec-driven" or "follow the spec process".
using-superpowers
This skill enforces mandatory workflows for discovering and using other Claude skills. It requires checking for applicable skills before any task, reading them with the Skill tool, and announcing usage. The skill mandates TodoWrite for checklists and provides specific rationalizations to avoid.
eds-block-development
Provides concrete guidance for developing Adobe Edge Delivery Services blocks using vanilla JavaScript. Covers file structure, Google Docs integration, DOM manipulation patterns, and critical EDS-specific constraints like reserved class names. Includes practical code examples for content extraction and error handling.
faber-debugger
A debugger skill for Faber workflows that diagnoses errors, proposes solutions, and maintains a persistent knowledge base of past resolutions. It works in targeted or automatic modes, logs findings to GitHub issues, and provides continuation commands for fixes.
