FAQ

What is a CLAUDE.md file?
A CLAUDE.md file is a project-level instruction file for Claude Code. Claude Code reads it to understand repository context, coding standards, commands, and rules before helping with work in that project.
What's the difference between a skill and an agent prompt?
A skill is a reusable Claude Code subtask template for a specific workflow. An agent prompt is a role or behavior instruction that tells an AI how to act, reason, and respond.
Can I share MCP server configs?
Yes. MCP server configs are welcome, but always remove API keys, tokens, private file paths, hostnames, and other secrets before publishing.
Are pastes public by default?
Yes. Pastes are public by default so others can discover and reuse them. You can choose login_required when you want viewers to sign in first.
How do I embed images in a paste?
Use standard Markdown image syntax: ![alt](url). The image URL must be publicly reachable so browsers can display it.
Is there a size limit?
Yes. Each paste can contain up to 200,000 characters.
