Give it a person's name or a vague need and it researches and distills their mental models, decision style and voice into a callable persona skill (e.g. Munger, Feynman, Jobs) to aid analysis and decisions. Works with Claude Code, Codex and other agents.

Local model gateway that routes requests from Claude Code, Codex and other coding agents to providers like DeepSeek, Kimi, Gemini and OpenRouter, with failover, rule-based routing and request logs. Bring your own API keys.

Trading research agent from HKU's HKUDS whose MCP server offers 70+ tools for quotes, financials, backtesting and research across A-shares, Hong Kong and US stocks and crypto. Needs local Python; HK, US and crypto research need no API key. For research only; not investment advice.

Distills technical books, doc folders or paper collections (PDF, EPUB, DOCX, Markdown and more) into an agent skill with a core framework, on-demand chapter files, glossary and cheat sheet for lookup while working. Extraction needs local Python; poppler or docling optional for PDFs.

Official CLI for Tencent's open-source knowledge base platform WeKnora: upload documents, manage knowledge bases, run hybrid search and answer questions from them, or serve as a read-only MCP. Needs your own WeKnora deployment and a source build with Go 1.26+.

Lets agents create and edit draw.io diagrams such as flowcharts and architecture diagrams in plain language, with live browser preview, version history and export to .drawio, PNG or SVG. Includes an embedded server; runs locally with no API key.

Claude Code plugin for Next AI Draw.io that starts its Draw.io MCP server via npx. Generate and edit flowcharts, architecture and sequence diagrams in plain language, with live browser preview, version history and .drawio export. Needs Node.js.

Command runner that saves and runs project commands in a justfile, with make-inspired but simpler syntax. Agents can use just --list to discover a project's build, test and deploy commands and run them directly.

HashiCorp's secrets management system: the vault CLI reads and writes secrets, issues dynamic database and cloud credentials on demand, encrypts and decrypts data, and manages leases and revocation. Needs a reachable Vault server.

Lightweight command-line JSON processor that slices, filters, maps and transforms JSON with concise expressions and no runtime dependencies. A staple for agents parsing API responses and logs.

Polyglot dev environment manager: declare Node, Python, Go and other tool versions, environment variables and project tasks in mise.toml; mise exec and mise run install tools on demand and run them, with one config shared by local and CI.

Terminal multiplexer written in Rust, an alternative to tmux, with layout files, floating and stacked panes, WebAssembly plugins and a built-in web client. Handy for running several agent sessions at once.
