clawhub is a skill for Claude Code, Codex from HKUDS/OpenOPC. It costs 37 tokens per session (434 once invoked), scanned A, original, MIT.

A tool for searching and installing skills from ClawHub, a public registry of reusable instructions for AI agents. It can also list installed skills and update them.

In plain words
What is it for?
Search for a skill by describing the needed capability, install it into a project, list installed skills, and update them.
Why use it?
It helps when a task needs knowledge or a workflow that is not already available in the project. It avoids having to create every specialized skill from scratch.

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 6d 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.

What it actually says

ClawHub

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

When to use

  • You encounter an unfamiliar domain or technology and need guidance
  • The user asks to find, search, install, or update skills
  • You need specialized knowledge that existing skills don't cover
  • A task requires capabilities beyond your current skill set
npx --yes clawhub@latest search "web scraping" --limit 5

Install

Install skills into the current project's skill directory:

npx --yes clawhub@latest install <slug> --workdir .opc/projects/<project_id>

Replace <slug> with the skill name from search results and <project_id> with the current project ID. This places the skill into .opc/projects/<project_id>/skills/<slug>/SKILL.md.

After install, read the installed SKILL.md with file_read to apply its guidance immediately.

Update

npx --yes clawhub@latest update --all --workdir .opc/projects/<project_id>

List installed

npx --yes clawhub@latest list --workdir .opc/projects/<project_id>

Workflow

  1. Search for relevant skills with a descriptive query
  2. Review search results and pick the best match
  3. Install the skill into the project directory
  4. Read the installed SKILL.md with file_read
  5. Follow the skill's instructions for the current task

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 must point to the project directory so skills install correctly.
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.
