A tool for creating, checking, packaging, and sharing Claude skills with a team through Slack. It creates the expected skill files and metadata, validates their format, and prepares a distributable package.

Use it to create a skill directory, package its files, validate the package, and announce it in a Slack channel for team discovery.

It reduces errors when making skills for other people to use and makes the team aware of new skills. Validation catches missing metadata and naming or structure problems before sharing.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add skillmds/skillmd --skill skill-share

Clone the repo

git clone --depth 1 https://github.com/skillmds/skillmd

Made for: Claude Code.

Or install create-agent-skills, the plugin that ships this one along with the rest of its 10 skills.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00027	$0.00607
Opus 5.5	$0.00011	$0.00243
Sonnet 5	$0.00005	$0.00121
Haiku 4.5	$0.00003	$0.00061

Security

Grade A, and why

skill-share scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

91% identical to skill-share — 17 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Use this skill when you need to:

Create new Claude skills with proper structure and metadata
Generate skill packages ready for distribution
Automatically share created skills on Slack channels for team visibility
Validate skill structure before sharing
Package and distribute skills to your team

Also use this skill when:

User says he wants to create/share his skill

This skill is ideal for:

Creating skills as part of team workflows
Building internal tools that need skill creation + team notification
Automating the skill development pipeline
Collaborative skill creation with team notifications

Key Features

1. Skill Creation

Creates properly structured skill directories with SKILL.md
Generates standardized scripts/, references/, and assets/ directories
Auto-generates YAML frontmatter with required metadata
Enforces naming conventions (hyphen-case)

2. Skill Validation

Validates SKILL.md format and required fields
Checks naming conventions
Ensures metadata completeness before packaging

3. Skill Packaging

Creates distributable zip files
Includes all skill assets and documentation
Runs validation automatically before packaging

4. Slack Integration via Rube

Automatically sends created skill information to designated Slack channels
Shares skill metadata (name, description, link)
Posts skill summary for team discovery
Provides direct links to skill files

How It Works

Initialization: Provide skill name and description
Creation: Skill directory is created with proper structure
Validation: Skill metadata is validated for correctness
Packaging: Skill is packaged into a distributable format
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"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
