SQLite Analyst
The open catalog of AI agent skills — 2,000+ security-scanned skills for Claude Code, Cursor, Codex, and more.
SQLFluff SQL Linter and Auto-Formatter
Lint and auto-format SQL code across 30+ dialects using SQLFluff. Enforces consistent style, catches syntax issues, and supports Jinja/dbt templating for ELT workflows.
sqlc Type-Safe SQL Code Generator
sqlc is a SQL compiler that generates type-safe Go, Python, Kotlin, and TypeScript code from plain SQL queries. You write SQL, run sqlc, and get fully typed data access functions with compile-time safety — no ORM, no reflection, no runtime query building.
Split Markdown front matter and body before docs migrations, metadata audits, or static-site transforms
Use gray-matter when an agent needs to open Markdown or content files, extract structured front matter, and pass clean body text plus metadata into the next step. This skill is for parsing and rewriting front matter safely, not for running a full CMS or static site generator.
Spleeter AI Audio Source Separation by Deezer
Spleeter is Deezer's open-source audio source separation library with pretrained models. It can split audio into 2, 4, or 5 stems (vocals, drums, bass, piano, accompaniment) and runs 100x faster than real-time on GPU, making it ideal for music production, remix, and audio analysi
Spin up isolated git worktrees for parallel Claude Code and Codex branches with Worktrunk
Create, switch, and clean per-branch worktrees so multiple coding agents can work the same repo in parallel without stomping each other.
SpiderFoot Open Source Intelligence Automation Framework
SpiderFoot is an open-source OSINT automation tool that queries over 200 data sources to gather intelligence about IP addresses, domain names, email addresses, and other targets. Written in Python, it provides both a web UI and CLI for reconnaissance, threat intelligence, and att
Spell-check docs and code comments with source-aware filters using pyspelling
Run filtered spell checks over Markdown, Sphinx, HTML, or code comments without flattening everything into one noisy text stream.
SpeechBrain PyTorch Conversational AI and Speech Processing Toolkit
SpeechBrain is an open-source PyTorch toolkit that accelerates conversational AI development. It provides recipes and pretrained models for speech recognition, speaker verification, speech enhancement, speech separation, language modeling, and text-to-speech across 40+ datasets.
Spectral OpenAPI and AsyncAPI Linter
Spectral is an open-source JSON/YAML linter by Stoplight with built-in support for OpenAPI 3.x, Swagger 2.0, AsyncAPI 2.x, and Arazzo 1.0. It enforces API style guides through custom and pre-built rulesets, ensuring consistency across all your API descriptions.
Apache Spark DataFrame ETL Pipeline
Automates PySpark DataFrame transformations including schema inference, partition pruning, and Delta Lake merge operations. Integrates with AWS Glue Data Catalog and Apache Iceberg table formats for lakehouse architectures.
SOPS Secret File Encryption and Rotation
SOPS manages encrypted YAML, JSON, ENV, INI, and binary files with KMS, age, and PGP. It is a tight fit for secrets handling, rotation, and encrypted configuration workflows.
SOPS Encrypted Secrets Editor and Manager
SOPS (Secrets OPerationS) is an editor of encrypted files that supports YAML, JSON, ENV, INI, and BINARY formats. It encrypts with AWS KMS, GCP KMS, Azure Key Vault, HuaweiCloud KMS, age, and PGP, making it the standard tool for managing secrets in version-controlled repositories
Sonic Fast Lightweight Schema-Less Search Backend
Sonic is a fast, lightweight, and schema-less search backend written in Rust. It serves as a drop-in alternative to Elasticsearch that runs on just a few megabytes of RAM, making it ideal for resource-constrained environments and edge deployments.
SonarQube Scanner Skill
Integrates SonarQube static analysis via the sonar-scanner CLI and SonarQube Web API. Fetches quality gate results from api/qualitygates/project_status, parses issues via api/issues/search, and maps findings to source lines for inline code review annotations.
SonarQube Rule Enforcement Agent
Integrates with SonarQube Web API and sonar-scanner CLI to enforce code quality gates across pull requests. Automatically blocks merges when critical code smells, security hotspots, or duplications exceed configurable thresholds.
SonarQube Quality Gate Monitor
Monitors SonarQube project quality gates via the Web API and blocks CI deployments when thresholds fail. Tracks technical debt trends across releases.
SonarQube Quality Gate Explainer
Fetches the latest SonarQube project analysis result, explains why the Quality Gate failed in plain English, and links to specific issues. Covers coverage drops, new bugs, and security hotspots. Supports SonarQube Server and SonarCloud. Diagnostic only.
SonarQube Quality Gate Enforcer
Enforces SonarQube quality gates in pull request workflows using the SonarQube Web API and ce/task endpoint. Blocks merges when code coverage drops, duplications exceed thresholds, or security hotspots are unreviewed.
SonarQube Quality Gate Checker
Queries SonarQube Web API for project quality gate status, code coverage metrics, and technical debt analysis. Integrates with sonar-scanner CLI for on-demand analysis and pr-decoration via the SonarQube ALM integration API.
SonarQube Quality Gate Agent
Monitors SonarQube quality gate status via the SonarQube Web API and enforces code quality thresholds. Parses coverage reports from JaCoCo, Istanbul, and lcov formats for multi-language projects.
SonarQube PR Gate
Integrates SonarQube quality gates into pull request workflows via the SonarQube Web API /api/qualitygates/project_status. Blocks merges when code smells, duplications, or coverage thresholds fail and posts inline annotations using the GitHub Checks API.
SonarQube Gate Enforcer
Enforces SonarQube quality gate conditions in CI pipelines using the SonarQube Web API /api/qualitygates/project_status endpoint. Blocks merges when coverage drops, duplications exceed thresholds, or new bugs are introduced.
SonarQube Gate Checker
Queries the SonarQube Web API (/api/qualitygates/project_status) to evaluate quality gate conditions before merge. Reports code smells, coverage thresholds, and duplications against configurable SonarQube quality profiles.
