FAQ
Common questions about using SkillBin. Back to home
Getting Started
What is SkillBin?
A pastebin for agent skills. Upload markdown files that define behaviors, tools, and workflows for AI coding agents, then share them with a short link or a named URL.
Do I need an account?
No. Anonymous uploads get a short link (/s/abc123). Signing in with GitHub gives you a username, custom slugs (/u/alice/my-skill), visibility controls, and version history.
Is SkillBin free?
Yes. SkillBin is free and maintained by Wallfacer.
Uploading Skills
How do I upload a skill?
You can paste your skill content directly on the homepage, or use the terminal command to pipe a local file. If you're signed in, your API token is included automatically so uploads are linked to your account.
What's the terminal upload command?
Run curl -fsSL https://skillb.in/upload | sh to upload a skill from your terminal. If you're signed in, copy the authenticated command from the homepage — it includes your API token so the skill is linked to your account.
Is there an API?
Yes. Every skill has a raw endpoint (/s/{id}/raw or /u/{username}/{slug}/raw) that returns the plain markdown content, suitable for curl or any HTTP client. Authenticated uploads are supported via your API token.
Is there a size limit?
Skills are text documents and are intended to be reasonably sized. Extremely large uploads may be rejected. If you're hitting limits, consider splitting your skill into multiple focused skills.
Managing Skills
What are slugs?
Slugs are optional human-readable identifiers for your skills. Instead of /s/abc123, a slug gives you a clean URL like /u/yourname/my-skill. Slugs must be lowercase letters, numbers, and hyphens, up to 64 characters.
Does SkillBin support versioning?
Yes. Skills with slugs automatically track versions. You can view the version history and access any previous version via /u/username/skill-name/v/1, /v/2, etc.
How do I install a skill?
Each skill page shows an install command you can copy. Run it in your terminal and it will download the skill to your local Claude Code skill directories.
How is skill content rendered?
Skills are rendered as markdown with GitHub-flavored markdown support (tables, task lists, strikethrough, etc.). You can toggle between the rendered view and the raw source on any skill page. Frontmatter fields are displayed as structured metadata.
Can I delete a skill?
Yes. If you're signed in and own a skill, you can delete it from the skill page. Anonymous skills (uploaded without an account) cannot be deleted by users — use the abuse report process instead.
Privacy & Visibility
What visibility options are available?
Skills with a slug can be set to Public (visible to everyone and listed on your profile), Unlisted (accessible via direct link but not listed on your profile), or Private (only visible to you). Anonymous skills without a slug are always public.
Who can see my skills?
Public skills are visible to anyone and appear on your profile page. Unlisted skills are accessible to anyone with the link but won't appear in listings. Private skills are only visible when you're signed in to your own account.
Are public skills indexed by search engines?
Public skills may be crawled and indexed by search engines. If you don't want a skill to appear in search results, set its visibility to Unlisted or Private.
Safety & Content Policy
What's the safety evaluation on skill pages?
SkillBin runs both static analysis and LLM-based safety checks on uploaded skills. These flag potentially dangerous patterns like shell commands, file system access, or network calls so you can review a skill's behavior before installing it.
What content is not allowed?
SkillBin is for sharing agent skills and related technical content. Don't upload malware, credential dumps, personal data, copyrighted material, spam, or content designed to exploit or harm users or systems. Skills that attempt to bypass safety measures in AI agents may be removed.
How do I report abusive content?
If you find a skill that violates the content policy or contains harmful material, email abuse@wallfacer.ai with the skill URL and a description of the issue.
Account
How do I sign in?
Click "Sign in with GitHub" in the top right. SkillBin uses GitHub OAuth — no separate password to manage. Your GitHub username becomes your SkillBin profile URL.
Can I change my username?
Your SkillBin username is your GitHub username. If you change your GitHub username, it will be reflected the next time you sign in.
How do I delete my account?
Email team@wallfacer.ai from the email associated with your GitHub account and we'll remove your account and all associated skills.
Do skills stay online forever?
Skills remain available as long as your account is active. Anonymous skills without an account may be subject to cleanup over time. There is currently no auto-expiration setting.
