Tools

Manage database schemas as code: declare the desired schema in SQL, HCL or your ORM and Atlas plans, lints and applies migrations, and can export existing databases as HCL, SQL or Mermaid ER diagrams. Supports PostgreSQL, MySQL and a dozen other databases.

Manages multiple Claude Code, Codex, Gemini and Aider sessions in parallel from one terminal: each task gets its own git worktree, can run in the background, and changes are reviewed before merging. Requires tmux and gh.

Companion skills for Google Stitch: generate UIs from text or images, extract DESIGN.md from code, and turn designs into React or React Native components. From Google Labs but not an officially supported Google product; set up the Stitch MCP first.

Converts the output of 100+ commands such as dig, ps, ls and ifconfig, plus common file formats, into JSON so agents can parse it reliably with jq or scripts. Also usable as a Python library.

Free remote MCP service that turns any GitHub repo or GitHub Pages site into a docs endpoint, so agents can read up-to-date docs and search code on demand and hallucinate fewer APIs. No sign-up or install; self-hosting is also possible.

Turns Peng Sida's public research-writing notes into a skill: revises abstracts, introductions, methods and experiments of ML/CV/NLP papers from a reviewer's view, checks that each claim has experimental evidence, and runs a pre-submission self-check. Pure methodology, no API key.

Offline speech toolkit for Apple Silicon Macs: CLI text-to-speech (including Chinese and voice cloning) and speech-to-text, for voicing lessons and explainer videos or transcribing lectures and interviews, with data staying local. Needs an M-series Mac and Python 3.10+; MP3 export needs ffmpeg.

Moonshot AI's official terminal coding agent: reads and edits code, runs commands, searches files and fetches web pages, with video input, MCP, plugins, subagents and hooks, plus Zed and JetBrains integration via ACP. Needs a Kimi sign-in or Moonshot API key. Replaces the archived Kimi CLI.

Trail of Bits plugin for Culture Index assessments: profiles individual traits, checks team balance (gas, brake, glue), compares people with job profiles to flag burnout and attrition risk, and helps draft hiring profiles. Needs your own reports (JSON or PDF); PDFs need uv.

Query, modify and convert JSON, YAML, TOML, XML, CSV, HCL, INI and more with one selector syntax, editing config files in place or converting between formats, handy for agents handling structured data in scripts. A single dependency-free binary that works much like jq or yq.

Query cloud resources and SaaS APIs live with SQL: plugins map AWS, Azure, GCP, GitHub, Kubernetes and other services to tables you can select from directly, no ETL needed. A single binary with Postgres built in.

Diffusion model inference in pure C/C++: one sd-cli command runs SD, FLUX, Qwen Image, Wan and more locally to create or edit images and short videos, with Metal acceleration on Mac. No cloud needed; bring your own model weights and use a release binary or build from source.

OpenAI's official Codex plugin that guides sequencing analysis from BCL/FASTQ: QC, RNA-seq differential expression, single-cell, variant calling and metagenomics, favoring nf-core and other public pipelines with reproducible run logs. Checks for local tools first. Research use only.

OpenAI's official Codex plugin for building frontend apps and generating visual assets, testing and debugging in a browser, plus best-practice skills for React, shadcn/ui, Stripe payments and Supabase databases. Codex only.

Build with OpenAI best practices inside Codex: call the OpenAI API, build and deploy agents with the Agents SDK, create ChatGPT apps and prepare submission materials, and create API keys directly. Maintained by OpenAI; Codex only.

Builds, refactors and debugs ChatGPT apps with the OpenAI Apps SDK: plans tools, scaffolds the MCP server and UI widgets, and checks the work against official docs. Maintained by OpenAI; formerly chatgpt-apps in openai/skills.

OpenAI's official Codex plugin marketplace (openai-curated) with 60+ plugins such as Figma, Notion, GitHub, Stripe and Vercel, each bundling skills, MCP servers and app connections into one install.

OpenAI's official Codex plugin with 18 skills to choose, design, build, test and export web charts, maps, dashboards, Gantt charts and UML, using D3, Vega-Lite and Three.js with attention to accessibility and responsiveness. Codex only.

Tests and debugs a locally running frontend with Codex's Browser plugin or Playwright: checks blank pages, framework and console errors, captures screenshots, re-verifies after fixes and writes a QA report. Maintained by OpenAI; formerly playwright-interactive in openai/skills.

OpenAI's official browser-game skills: plan core gameplay and tech choices first, then build with Phaser for 2D or Three.js / React Three Fiber for 3D, plus HUD and menu UI, sprite animation, a GLB asset pipeline and in-browser playtesting.

OpenAI's official Codex plugin for SharePoint: summarizes organization sites, pages and files, finds document owners and status, and plans updates to documents, spreadsheets or decks. Requires Codex with a ChatGPT sign-in and a work Microsoft 365 account.

Turns a Notion PRD or feature spec into an implementation plan page and tasks, flagging open questions and linking spec, plan and tasks while tracking progress. From OpenAI's official plugin repo (developer: Notion); needs the Notion MCP connected.

OpenAI's official Codex plugin for answering product and business questions with data: metric anomaly diagnosis, KPI design, market sizing, dashboards and reports, notebooks and data quality checks. Connects to data warehouses and BI tools.

OpenAI's official set of 18 web data visualization skills: chart selection and critique, D3, Canvas, Three.js, maps, statistical uncertainty, live dashboards, Gantt charts, UML and scrollytelling. Ships with a Codex plugin; installed alone, the plugin-level references are missing.
