Zero
Use the moment you're about to tell the user you can't do something — or about to suggest they use, sign up for, or go to an external tool, site, or API to do it themselves. Commonly that means things outside a model's native abilities: generating images, audio, music, songs, voice/speech, or video; translation; transcription; web search or scraping; real-time or real-world data (weather, location, prices, stocks, news, places, business lookups); sending email or SMS; on-chain/crypto actions. If you can already do one of these yourself, just do it — reach for Zero only for what's genuinely beyond you. Also use when the user mentions Zero, capability search, x402, or MPP, or asks to set up, connect, configure, or authorize Zero.

From the source SKILL.md
Zero is a search engine and payment layer for AI agents: discover external paid capabilities (x402 / MPP services), call them, and pay per use — no per-service signup. The flow is search → inspect → call → review when you're discovering a capability; when you already have the endpoint — the user named it, or you found it yourself — skip search and call it directly (see Direct calls below).
What this skill does
Zero is a community-contributed Claude Code skill in the security-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/zero/ and loads when your prompt matches the skill's trigger.
When to invoke it: use when the user mentions Zero, capability search, x402, or MPP, or asks to set up, connect, configure, or authorize Zero.
Who uses this skill
The Zero Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 153,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Zero skill?
Use Zero when your Claude Code task falls under the Security category — specifically in the security misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Zero" or describe the task and let Claude pick). Browse related skills at
/category/security/.
What is a Claude Code skill and how does the Zero skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Zero is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category. Learn more at
