Each tab says whether it installs commit 35e1ea2, the one we checked, or the latest version.
No tab for your agent? Use Any agent for OpenCode, Goose, Windsurf (Devin Desktop), Zed, Roo Code, Factory Droid, Junie, Amp and Antigravity, and Claude Code for Cline. Kiro needs the folder copied by hand.

npx skills@1.7.4 add Prat011/awesome-llm-skills --skill slack-gif-creatorWhat it can touch
From the files and frontmatter at commit 35e1ea2. This is how much a skill can do, not whether it is risky.
What it can touch: Shell, network or credentials
Runs shell commands
Its instructions or files give the agent commands to run on your computer.
Reaches the network
It sends or fetches data over the internet, for example with curl, an HTTP library or a package install.
Names web addresses
It mentions outside web addresses the agent may visit. We list them but don't follow them.
Bundles scripts
The folder holds code files the agent may run.
Pattern check
Pattern check: nothing flagged · commit 35e1ea2 · 27 Oct 2026
We checked every text file in this skill, at commit 35e1ea2 on 27 Oct 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

Format check
Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.
Agent Skills specPasses with warnings
The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.
- Warning
The body is 640 lines; the spec suggests under 500. B1
Fix: Move detailed sections into reference files and link to them from SKILL.md.
- Warning
Claude CodePasses
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.
- Note
The body is 640 lines; the spec suggests under 500. Claude Code's docs say the same. B1
Fix: Move detailed sections into reference files and link to them from SKILL.md.
- Note
Claude apps & API uploadPasses
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Note
The description is 274 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
- Note
The body is 640 lines; the spec suggests under 500. Anthropic's guidance says the same. B1
Fix: Move detailed sections into reference files and link to them from SKILL.md.
- Note
- OpenAI (Codex & API)Passes
- VS Code & CopilotPasses
