skill-share is an agent skill that creates validated Claude skill packages with SKILL.md scaffolds and posts announcements to Slack channels via Rube.

About

skill-share is a Composio skill for creating and distributing Claude skills with automatic Slack team notifications through Rube. It activates when users want to create or share a skill, building properly structured directories with SKILL.md, scripts/, references/, and assets/ folders plus hyphen-case naming conventions. Validation checks SKILL.md format, required metadata fields, and naming rules before packaging. Packaging produces distributable zip files that include all assets and documentation after validation passes. Slack integration via Rube posts skill metadata including name, description, and links to designated channels using SLACK_SEND_MESSAGE, SLACK_POST_MESSAGE_WITH_BLOCKS, and SLACK_FIND_CHANNELS. The five-step flow initializes with a skill name and description, creates the directory scaffold, validates metadata, packages the zip, and posts a team announcement. Example usage creates skill-pdf-analyzer with template directories and posts New Skill Created to Slack. Requirements include a Slack workspace via Rube, write access to the skill directory, and Python 3.7 or newer for creation scripts.

Create structured Claude skills with validated SKILL.md metadata, package them as zip files, and announce new skills to Slack via Rube.

Who is it for?

Skip if: Skip when you only need to edit an existing skill without packaging or when Slack via Rube is not connected.

When should I use this skill?

User creates a new Claude skill, packages skills for distribution, or wants automatic Slack announcements for skill discovery.

How It Works

1. Initialization: Provide skill name and description 2. Creation: Skill directory is created with proper structure 3. Validation: Skill metadata is validated for correctness 4. Packaging: Skill is packaged into a distributable format 5. Slack Notification: Skill details are posted to your team's Slack channel

Example Usage

When you ask Claude to create a skill called "pdf-analyzer":
1. Creates /skill-pdf-analyzer/ with SKILL.md template
2. Generates structured directories (scripts/, references/, assets/)
3. Validates the skill structure
4. Packages the skill as a zip file
5. Posts to Slack: "New Skill Created: pdf-analyzer - Advanced PDF analysis and extraction capabilities"
