This skill provides guidance for exactly that: creating a skill, adding it to a plugin, organizing its content, and improving its description. Reach for it any time you are building a skill or tidying one up. ### Top 3 things it does for you - Create a new skill for a plugin - Improve a skill's description - Organize what goes inside a skill ## Information **Skill Development at a glance** | | | | --- | --- | | Kind | Skill | | Publisher | [Anthropic](/@anthropics) | | Category | [Developer Tools](/category/devtools) | | Works with | Agent Skills - an open standard supported by 40+ agents | | Languages | en | | Version | 0.1.0 | | Size | 34 KB | | Licence | _Not recorded_ | | Repository | [anthropics/claude-code](https://github.com/anthropics/claude-code/tree/cc898dc3692fb583f36ab327942aad20b7d3dbd0/plugins/plugin-dev/skills/skill-development) | | GitHub stars | 155,070 (as of Nov 2026) | | Installs | 19,661, counted by skills.sh (Nov 2026) | ## Security report **Verified.** AIR scanned this exact version of Skill Development and flagged nothing.

A different version is a different artifact, and nothing here applies to a version AIR has not scanned. [Read the full security report for Skill Development](/security/skill-development) ## About Skill Development Reach for this when you sit down to create a new skill for Claude Code, or to add a skill to an existing plugin. It offers guidance on the shape of the thing: how to structure a skill, how to organize its content, and where ideas like progressive disclosure fit in. Skill development best practices for Claude Code plugins run through all of it. It also earns its place after a skill already exists. If the description no longer serves, this helps you improve it, and if the content has lost its arrangement, it helps you organize it again. ## What's inside - SKILL.md - instructions - references/skill-creator-original.md - reference ## Questions ### Is Skill Development safe to install? AIR scanned this exact version of Skill Development and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit cc898dc3692f, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/skill-development. ### How do I install Skill Development? Open https://airmarket.ai/app/skill-development on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up.
