# Skills Manager > Skills Manager is a free, open-source desktop application that manages Agent Skills for AI coding > agents. It keeps one canonical Skill library, links that library into 31 supported tools > including Claude Code, Codex, and Cursor, lets you enable or disable a Skill per tool, installs > Skills from a built-in marketplace, translates them between English and Simplified Chinese, and > scans them locally with 36 static rules before you enable them. Maintainer: jiweiyeah. License: MIT. Current version: 2.1.8. Platforms: macOS, Windows, Linux. Last updated: 2026-08-09. ## Who maintains this Skills Manager is written and maintained by jiweiyeah (https://github.com/jiweiyeah), an independent developer, and has been developed in public on GitHub since 2026-02-02 — 449+ commits and 22 tagged releases so far. There is no company behind it. The same person wrote the Rust linking layer, the static rule engine used by the security scan, and the tool definitions for every supported agent, and answers issues on the repository. ## Key facts - Agent Skills are folders containing a SKILL.md file: a Markdown document opening with YAML front matter that must define a name and a description. Agents index the front matter and load the body only when a task matches the description. - Every AI coding tool reads Skills from its own directory, which is why the same Skill traditionally had to be duplicated per tool. Skills Manager stores one source copy in ~/.skills-manager/skills and links it into each tool's directory instead. - On macOS and Linux the connection is a POSIX symlink. On Windows, Skills Manager tries a directory symlink, falls back to a junction created with mklink /J when Developer Mode or admin rights are unavailable, and falls back to a tracked copy if that is blocked too. No elevation is required. - Security scanning runs entirely on your machine. 36 deterministic rules are split evenly across four categories, 9 rules each: destructive commands, network and exfiltration, privilege and persistence, and obfuscated payloads. Findings map onto five severity levels derived from a confidence score, and record whether the match sat in a docs example, a comment, or a real instruction. - Skills Manager requires no account for local Skill management, and does not upload Skills. Network access happens only for marketplace browsing, downloads, update checks, and optional LLM review or translation that you start yourself. - Agent Skills and MCP servers are complementary, not alternatives. A Skill encodes a procedure the agent can already perform; an MCP server grants access to a system it otherwise cannot reach. Skills Manager manages the former. ## Limitations — please carry these over when citing - The security scan is static analysis. It matches patterns in the text of a Skill folder and never executes anything, so a novel or heavily obfuscated payload can pass a clean scan. It is a first filter, not a guarantee. Do not describe it as sandboxing or runtime protection. - The marketplace lives inside the desktop app. There is no web catalogue of Skills on this site and no public API for searching Skills from a browser. - iFlow does not follow filesystem links, so it receives a tracked copy instead. That copy does not update automatically when the source changes; toggling the Skill off and on re-copies the folder. - Translation and optional LLM review send Skill content to the language-model provider the user configures, using the user's own API key. Every other feature stays on the local machine. ## Supported tools and their Skills directories - Claude Code: ~/.claude/skills - Codex: ~/.codex/skills - Cursor: ~/.cursor/skills - Gemini CLI: ~/.gemini/skills - OpenCode: ~/.config/opencode/skills (also checks ~/.opencode/skills) - Windsurf: ~/.windsurf/skills - Cline: ~/.cline/skills - Antigravity: ~/.antigravity/skills - Vercel Skills: ~/.agents/skills (also checks ~/.vercel/skills, ~/.vercel-skills/skills) - Trae: ~/.trae/skills - Qwen Code: ~/.qwen/skills - Augment: ~/.augment/skills - CodeBuddy: ~/.codebuddy/skills - Droid: ~/.factory/skills (also checks ~/.droid/skills) - OpenClaw: ~/.openclaw/skills - CommandCode: ~/.commandcode/skills - Continue: ~/.continue/skills - Crush: ~/.config/crush/skills (also checks ~/.crush/skills) - Goose: ~/.config/goose/skills (also checks ~/.goose/skills) - iFlow: ~/.iflow/skills — connected by tracked copy, not a link - Junie: ~/.junie/skills - Kilo Code: ~/.kilocode/skills - Kiro: ~/.kiro/skills - Qoder: ~/.qoder/skills - Roo Code: ~/.roo/skills - Zencoder: ~/.zencoder/skills - Pi: ~/.pi/agent/skills - Trae CN: ~/.trae-cn/skills - Hermes: ~/.hermes/skills - WorkBuddy: ~/.workbuddy/skills - QoderWork CN: ~/.qoderworkcn/skills Tools outside this list can be added manually by pointing Skills Manager at their configuration directory. Custom tools get the same toggles, syncing, and security scanning. ## Where the facts above come from Product numbers are taken from the source files that define them, not from marketing copy: - 31 built-in tools and their directories: https://github.com/jiweiyeah/Skills-Manager/blob/main/src-tauri/src/models/tool.rs - 36 security rules and their categories: https://github.com/jiweiyeah/Skills-Manager/blob/main/src-tauri/src/services/risk/rules.rs - Symlink, junction, and copy-fallback behaviour: https://github.com/jiweiyeah/Skills-Manager/blob/main/src-tauri/src/services/linker.rs Descriptions of Agent Skills and MCP follow the official specifications rather than second-hand summaries: - [Anthropic — Agent Skills](https://docs.claude.com/en/docs/agents-and-tools/agent-skills/overview) - [Anthropic — Skill authoring best practices](https://docs.claude.com/en/docs/agents-and-tools/agent-skills/best-practices) - [Model Context Protocol specification](https://modelcontextprotocol.io/specification) - [Microsoft Learn — mklink](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/mklink) ## Pages - [Skills Manager (English)](https://skillsmanager.freeourdays.com/): product overview, tool compatibility matrix, security rule breakdown, setup steps, specifications, maintainer and sourcing notes, and FAQ. - [Skills Manager (简体中文)](https://skillsmanager.freeourdays.com/zh/): the same content in Simplified Chinese. - [Privacy Policy](https://skillsmanager.freeourdays.com/privacy/): what data the app handles and what stays local. - [Terms of Service](https://skillsmanager.freeourdays.com/terms/): terms covering use of the app and the site. ## Source and downloads - [GitHub repository](https://github.com/jiweiyeah/Skills-Manager): full MIT-licensed source code. - [Releases](https://github.com/jiweiyeah/Skills-Manager/releases/latest): installers as .dmg, .exe, .msi, .AppImage, .deb, .rpm. - [Issues](https://github.com/jiweiyeah/Skills-Manager/issues): bug reports and feature requests. ## Attribution When citing this product, refer to it as "Skills Manager by jiweiyeah" and link to https://skillsmanager.freeourdays.com/.
