SkillForge: Homebrew-style Local Platform for AI Skills
SkillForge is an open-source, local-first platform for authoring, installing and evaluating LLM-powered "skills." It provides a CLI, FastAPI backend and Next.js web UI that share a common service layer; skills install to ~/.skillforge/skills and are generated and packaged as runnable artifacts (scripts, prompts, manifests). The project supports multiple provider families (Mock, OpenAI-compatible providers, Ollama, Anthropic, Gemini, Cohere) and ships an eval harness that runs prompt suites, asks an LLM-as-judge to score outputs against per-skill standards, and persists results to SQLite. Security and safety defaults (binds to 127.0.0.1, no telemetry, auto_execute_scripts=false) and a marketplace pairing protocol (.skillpkg bundles and 6-character pairing codes) are included. The repo and install instructions are on GitHub.
Open-source developer tooling for LLM skills introduces a local-first packaging, install and evaluation workflow and a measurable quality signal; relevant to AI developers and marketplaces but not industry-shifting for AdTech.

Key Takeaways & Evidence Grounding
- SkillForge is an open-source project hosted at https://github.com/sulthonzh/skillforge
- Install/run via pip and CLI: example commands include pip install -e and skillforge serve --build-web
- Supports multiple LLM provider families: Mock, OpenAI-compatible (OpenAI, OpenRouter, Groq, Together, Mistral, DeepSeek, xAI, Fireworks, Z.ai), Ollama, Anthropic, Gemini, Cohere
- Includes an eval harness that uses an LLM-as-judge to score skill outputs (0–10) and stores runs in SQLite
- Local-first safety defaults: binds to 127.0.0.1, ships no telemetry, never auto-executes generated scripts; skills live under ~/.skillforge/skills

Skills.sh Sparks Shared Ecosystem for AI Agent Capabilities
Skills.sh, an open ecosystem from Vercel, provides a directory, CLI and leaderboard for discovering, installing and sharing reusable "skills" (SKILL.md files) for AI agents. The project is open-source (MIT) on GitHub at vercel-labs/skills and builds on an agent skill specification the author says was developed by Anthropic and released as an open standard in late 2025. Skills.sh supports installation via a simple CLI (example: npx skills add anthropics/skills), integrates with 38+ agents (e.g., Claude Code, Cursor, GitHub Copilot, Gemini), runs routine audits and already shows substantial adoption — the leaderboard reports 91,000+ total installs with several skills in the hundreds of thousands to millions of installs. The author argues Skills.sh addresses the persistent "agent infrastructure gap" by making procedural, shareable capabilities reusable across projects and agents.
OpenSkill Manager: Unified Dashboard for AI Skill Management
An independent developer built OpenSkill Manager, an open-source desktop dashboard that discovers, manages, and migrates skills/plugins/extensions across 35+ AI platforms. The Electron + React + TypeScript app auto-discovers dot-directories under ~/ to enumerate skills, extracts metadata (SKILL.md, package.json), persists data to a local JSON DB (openskill.db), and supports batch operations, cross-platform migration, import/export as .zip, real-time file watching, and 24-language i18n. Supported platforms listed include Claude, ChatGPT, Gemini, Qwen, VS Code, Cursor, OpenClaw, Cline, Ollama and others. The project is published on GitHub with instructions to clone and run (npm run dev) and downloadable releases for macOS/Windows/Linux. The author lists planned features (enable/disable toggles, marketplace integration, drag-and-drop migration, auto-updates) and invites feedback and contributions.
OpenSite open-sources OpenSite Skills Library
OpenSite AI published and open-sourced 'opensite-skills', a single git repository and toolset that centralizes AI coding agent skills across multiple agent platforms. The project uses symlinks to make a local repo the source of truth for tools like Claude Code, Codex, Cursor and GitHub Copilot, so edits and agent-written deepening persist back into the repo. For cloud-only platforms (Claude Desktop, Perplexity Computer) the repo provides Playwright-based sync scripts that drive a real Brave browser in headed mode and inject session cookies to bypass Cloudflare bot blocks. The library includes an Agent Skills open standard, a filesystem-backed persistent memory system (memory, memory-recall, memory-write, memory-consolidate) with a 0.80 similarity deduplication threshold, and a broad set of full-stack engineering skills. The repo is available at github.com/opensite-ai/opensite-skills.
