Stable Diffusion LoRA Training Pipeline
Orchestrates LoRA fine-tuning for Stable Diffusion XL using the diffusers library and Kohya ss-scripts. Manages dataset preparation with BLIP-2 auto-captioning, configures AdaFactor optimizer parameters, and exports safetensors checkpoints with A1111 metadata embedding.
Stable Diffusion ControlNet Pose Pipeline
Orchestrates Stable Diffusion image generation with ControlNet pose conditioning via the Automatic1111 API. Chains OpenPose detection, depth estimation, and img2img endpoints.
Stable Diffusion ControlNet Pipeline
Automates image generation workflows using Stability AI ControlNet API with depth maps, edge detection, and pose estimation. Integrates with Hugging Face diffusers library for model management and CLIP interrogator for prompt refinement.
Stable Diffusion ControlNet Compositor
Orchestrates Stable Diffusion XL with ControlNet preprocessors (Canny, Depth, OpenPose) for guided image generation. Manages ComfyUI workflow JSON exports and A1111 API batch processing.
Stable Diffusion ComfyUI Workflow Runner
Executes ComfyUI workflow JSON files against a local or remote ComfyUI server via its REST API. Supports LoRA loading, ControlNet conditioning, and queue management with progress polling.
SSL/TLS Certificate Validator and Monitor
Validates SSL/TLS certificates using OpenSSL s_client, checks OCSP stapling status, and monitors expiry dates. Integrates with crt.sh Certificate Transparency logs and SSLLabs API for grading.
SSL Certificate Chain Validator
Performs deep TLS certificate chain validation using OpenSSL and Certificate Transparency logs. Monitors expiration dates via the crt.sh API and checks OCSP responder status.
SSL Certificate Auditor
Audits TLS/SSL configurations using sslyze Python library and SSL Labs API v3. Checks certificate chain validity, HSTS headers, and OCSP stapling status with Certificate Transparency log verification.
sqruff High-Performance SQL Linter and Formatter
A fast SQL linter and formatter written in Rust by Quary Labs. sqruff provides advanced configurable linting and automated formatting with significantly faster execution than Python-based alternatives, plus a browser playground for quick experimentation.
sqlite-vec Vector Search Extension for SQLite
sqlite-vec is a lightweight SQLite extension for vector similarity search. Written in pure C with zero dependencies, it runs anywhere SQLite runs—Linux, macOS, Windows, WASM in browsers, and Raspberry Pis—and supports float, int8, and binary vector storage.
sqlite-utils Python CLI for SQLite Database Manipulation
sqlite-utils is a Python CLI utility and library by Simon Willison for manipulating SQLite databases. It lets you pipe JSON, CSV, or TSV data directly into SQLite, run in-memory SQL queries against files, configure full-text search, and perform schema transformations — all from t
SQLite MCP Server
Lightweight local database access for agent tasks.
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.
