Vault Transit Secrets Envelope Verifier
Verifies encryption workflows with HashiCorp Vault Transit endpoints like `/encrypt`, `/decrypt`, and `/rewrap`, plus key metadata inspection. Useful for agents reviewing whether application secrets handling is actually using envelope encryption correctly instead of assuming the
Vault Secrets Rotator
Manages secret lifecycle through the HashiCorp Vault HTTP API v1. Rotates database credentials via Vault dynamic secrets engine and syncs to Kubernetes via External Secrets Operator CRDs.
Vault Secrets Rotation Orchestrator
Automates HashiCorp Vault secret rotation using the Vault HTTP API and dynamic secrets engines. Manages database credential leases, PKI certificate renewal, and AWS STS token rotation with zero-downtime rollover.
Validate Python Docstrings Against Function Signatures with pydoclint
Check that Python docstrings stay consistent with parameters, returns, and raised exceptions as code evolves.
Validate lint bundle and unit-test JSON Schema repositories before release with JSON Schema CLI
Catch broken schemas, bad references, anti-patterns, and inconsistent formatting before a schema repo or contract bundle ships downstream.
Validate Kubernetes manifests against upstream schemas before cluster apply
Uses kubeconform to validate Kubernetes manifests against versioned schemas before anything touches a cluster. The agent can review rendered Helm output, raw manifests, or PR diffs and return invalid resources, missing schemas, and strict-mode failures without requiring live clus
Validate JSON data and config files against schemas with ajv-cli
Run schema checks from the shell or CI so malformed JSON, JSON5, or YAML inputs fail before they reach downstream tooling.
Validate, dry-run, and expose YAML agent runbooks as MCP tools with DeclarAgent
Turn YAML runbooks into auditable agent actions with validation, dry-runs, destructive-step approval, and optional MCP exposure.
Validate CloudFormation templates before deploy with cfn-lint
Catch CloudFormation schema, region, and intrinsic-function mistakes before a stack update fails in review or deployment.
Validate CI and app config files against upstream JSON schemas before merge
Use check-jsonschema when an agent needs to catch broken GitHub Actions, Renovate, Azure Pipelines, and other schema-backed config files before they hit CI. The agent picks the right schema hook, validates the changed files, and reports the exact key or structure that drifted fro
Vale Prose Linter for Technical Documentation
Vale is an open-source, markup-aware prose linter that enforces editorial style guides on technical documentation. This skill enables agents to run Vale against Markdown, AsciiDoc, reStructuredText, and HTML to catch style, grammar, and terminology issues.
uv Ultra-Fast Python Package and Project Manager
uv is an extremely fast Python package and project manager written in Rust by Astral (creators of Ruff). It replaces pip, pip-tools, pipx, poetry, pyenv, virtualenv, and twine with a single tool that resolves and installs packages 10-100x faster.
usql Universal Command-Line SQL Client for Multiple Databases
usql is a universal command-line interface for SQL databases including PostgreSQL, MySQL, SQLite, Oracle, SQL Server, and dozens more. It provides a consistent psql-like experience with syntax highlighting, tab completion, and cross-database copying.
Use RAGFlow as a retrieval and context layer for agent workflows
Build a supervised RAG context layer with RAGFlow so agents can index documents, retrieve grounded context, and answer with traceable source support.
Use an escalating scrape strategy in Claude Code before reaching for browser automation
Start with cheap static fetches, escalate to a browser only when needed, validate findings, and turn the result into a production-ready scraping approach.
Uptime Robot Status Page Webhook Alerter
Integrates with the Uptime Robot API to monitor status page changes and push webhook alerts to Slack or PagerDuty. Uses the UptimeRobot getMonitors endpoint to detect downtime transitions.
Uptime Robot Multi-Check Coordinator
Manages bulk uptime monitoring via the Uptime Robot API v2. Creates HTTP, keyword, and port monitors with alert contacts, maintenance windows, and status page synchronization.
Uptime Kuma Status Sync
Interfaces with the Uptime Kuma Socket.IO API to monitor service health checks. Syncs status page data to Statuspage.io via Atlassian REST API and triggers incident workflows in Rootly.
Uptime Kuma Self-Hosted Uptime Monitoring Platform
Uptime Kuma is an open source uptime monitor for HTTP, TCP, ping, DNS, Docker, and keyword checks. It gives agents a concrete way to create, update, and review monitors, incidents, notifications, and public status pages from a self-hosted monitoring stack.
Upstash MCP Server for Redis and QStash Management
An official MCP server from Upstash that lets AI agents manage Redis databases, QStash message queues, and Vector stores through natural language. Supports database creation, key operations, backups, and throughput analytics via the Model Context Protocol.
Upscayl Open Source AI Image Upscaler
Upscayl is a free, open-source AI image upscaler for Linux, macOS, and Windows. It uses Real-ESRGAN models with Vulkan GPU acceleration to enhance low-resolution images, supporting batch processing, custom models, and multiple output formats.
Upptime GitHub Actions Uptime Monitor and Status Page
An ASE skill built around Upptime, the open source uptime monitor and status page system powered by GitHub Actions, Issues, and Pages. It is a strong fit when an agent needs lightweight endpoint monitoring, incident issue tracking, and a public or internal status site without mai
Update repository docs automatically after code changes and open review PRs
Use GitHub Next's update-docs workflow when code changes should trigger documentation maintenance instead of waiting for humans to remember it later. The agent analyzes what changed, generates the missing docs updates, and opens a reviewable PR rather than silently rewriting the
Unstructured Document Partitioning and ETL Library for LLM Pipelines
Unstructured is an open-source library for ingesting and partitioning PDFs, HTML, Office documents, emails, and other unstructured inputs into structured elements and metadata. It is commonly used as a preprocessing layer for RAG, search, extraction, and downstream AI pipelines.
