Skiller
A desktop application that installs, syncs and manages AI agent skills across many coding tools at once, so a skill added in one place propagates to every supported agent instead of being configured separately in each.
Skiller gives a single dashboard showing every detected agent, its installed skills and their status, and lets a skill be installed once and propagated to the rest of the agent stack with one click. Other functions include copying every skill from one agent to another or wiping them all per agent, pinning a skill to a specific repository without affecting the global setup, editing a SKILL.md file with immediate local visibility, and browsing marketplace sources such as skills.sh and ClawHub.
It natively supports 49 agents, including Claude Code, Codex, Gemini CLI, Copilot CLI, OpenCode, Cursor, Windsurf, Cline and Warp Terminal, auto-detecting any of them the moment they are installed with no separate setup. Project skills follow the shared .agents/skills/ convention wherever an agent supports it, and Skiller reads the Skills CLI's own global lock file strictly read-only, so that CLI remains the owner of update history.
It is built as an Electron desktop app in TypeScript, and its license is not asserted in its repository metadata.
