skilld-dev/skilld

What it solves

skilld provides a curated, human-authored registry of "Skills"—standardized instructions and supporting files—that can be shared across different AI agents (such as Claude Code, Cursor, and Gemini CLI). It solves the problem of fragmented agent configuration and the difficulty of discovering and installing trusted, version-controlled instructions for specific tasks or tools.

How it works

The project consists of a CLI tool and a registry (skilld.dev). A "Skill" is a directory containing a SKILL.md file following the Agent Skills format. Users can search for skills, run them for a single session (printing instructions for the agent to follow), or install them permanently into their agent's configuration. The CLI handles version tracking via Git commits, verifies the integrity of skills through immutable artifacts and attestations, and manages installation across multiple agent targets.

Who it’s for

Developers and AI agent users who want to extend the capabilities of their AI coding assistants or CLI agents with curated, community-driven instructions without manually copying and pasting prompts.

Highlights

• Cross-Agent Compatibility: A single command installs a skill for multiple supported agent targets (e.g., Claude Code, Codex, Cursor).
• Human-Curated: Every skill is linked to a human author and a specific GitHub repository for transparency.
• Verified Delivery: Uses immutable artifacts and attestations to ensure the downloaded skill matches the source commit.
• Session-Based Execution: The run command allows users to preview and apply a skill for one session without making permanent changes to the system.
• Native Performance: Distributed as a native binary via npm to avoid runtime dependencies.
