Is the Skill Share skill free?

Yes. The skill itself is free from frostant/awesome-claude-skills. SkillProof publishes the install command and an independent test verdict at no cost.

How do I install Skill Share?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Skill Share with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Didn't pass
Tested: Jul 30, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 30, 2026 · 7d50a28

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 30, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

Asked for a csv-cleaner skill, built and shared, both ways. Unassisted I shipped a working skill — SKILL.md with a trigger-shaped description plus scripts/clean.py, which I ran on a messy file and it normalized the headers and dropped 2 of 4 rows correctly. Following skill-share verbatim produced a two-line SKILL.md, three empty directories and a zip containing no logic at all, because the body never says to write any; strictly worse than doing it unassisted. The Slack step, which is the skill's only original idea, is unmeasured here — it calls Rube tool names (SLACK_SEND_MESSAGE, SLACK_FIND_CHANNELS) that need a connector and workspace OAuth this test could not reach. Its frontmatter also cites a LICENSE.txt that does not exist in the folder, though nine sibling skills in the same repo have one, and the repo's own skill-creator covers three of the four advertised features with actual Python scripts.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

Installs cleanly 3/5
Triggers reliably 4/5
Output vs. baseline 3/10
Docs & honesty 1/5

What Skill Share does

Describes a workflow for creating a Claude skill, validating its frontmatter, zipping it and announcing it to a Slack channel through the Rube MCP connector. In practice the folder contains a single markdown file — no creation, validation or packaging scripts exist, and the Slack half needs a Rube connection the skill does not help you set up. The same repository ships skill-creator, which does the creation, validation and packaging with real Python scripts.

How to install Skill Share

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.

Commands — how to trigger Skill Share

/skill-share Prose-only skill scaffolder that posts to Slack via Rube; ships no scripts

It also activates on plain-language prompts like these:

Help me package my csv-cleaner skill and post it to our Slack skills channel
Create a new Claude skill called csv-cleaner and validate its frontmatter
Build a skill scaffold, zip it, then announce it to the team via Rube
