clawhub

A public registry for finding and installing skills for AI agents.

In plain words
What is it for?
Use it to search for skills, install a skill by name, list installed skills, or update all installed skills.
Why use it?
It helps when you need an existing skill but do not know where to find one, and avoids installing it into the wrong workspace.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

clawhub scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

88% identical to clawhub — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

ClawHub

Public skill registry for AI agents. Search by natural language (vector search).

When to use

Use this skill when the user asks any of:

  • "find a skill for …"
  • "search for skills"
  • "install a skill"
  • "what skills are available?"
  • "update my skills"
npx --yes clawhub@latest search "web scraping" --limit 5

Install

npx --yes clawhub@latest install <slug> --workdir ~/.PhyAgentOS/workspace

Replace <slug> with the skill name from search results. This places the skill into ~/.PhyAgentOS/workspace/skills/, where PhyAgentOS loads workspace skills from. Always include --workdir.

Update

npx --yes clawhub@latest update --all --workdir ~/.PhyAgentOS/workspace

List installed

npx --yes clawhub@latest list --workdir ~/.PhyAgentOS/workspace

Notes

  • Requires Node.js (npx comes with it).
  • No API key needed for search and install.
  • Login (npx --yes clawhub@latest login) is only required for publishing.
  • --workdir ~/.PhyAgentOS/workspace is critical — without it, skills install to the current directory instead of the PhyAgentOS workspace.
  • After install, remind the user to start a new session to load the skill.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
