What it does
Clawhub Manage is an agent skill from aws-samples/sample-host-openclaw-on-amazon-bedrock-agentcore, published by the product's own GitHub organization. Install, uninstall, and list ClawHub community skills. Use when the user asks to install a new skill, remove an existing skill, or see what skills are available. Installed skills are recorded per user and reinstalled automatically a few seconds after each new session starts.
Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files (for example `common.js`, `install.js` and `list.js`).
It sits in Agent Workflows, covering Skill management. It works with Reddit. The licence is MIT-0.
When your agent uses it
- The user asks to install a new skill
- Remove an existing skill
- See what skills are available
Example prompts
- “/clawhub-manage”
Requirements
- Node.js
- Pre-approved tools (allowed-tools): Bash(node:*)
What it can do on your machine
Read from SKILL.md and the folder at commit b0c427f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash(node:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
node
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Clawhub Manage loads about 593 tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 246 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Usage
install_skill
Install a community skill from the ClawHub marketplace.
node {baseDir}/install.js <skill_name>skill_name(required): The skill name from ClawHub (e.g.,baidu-search,reddit-readonly)
uninstall_skill
Remove a previously installed skill.
node {baseDir}/uninstall.js <skill_name>skill_name(required): The skill name to remove
list_skills
List all installed ClawHub skills.

transcript - "What skills are installed?" -> list_skills
- "Show me available skills" -> list_skills
Notes
- Installs go to
/skillsand are recorded, with the installed version pinned, in the user's persistent state (~/.openclaw/runtime-skills.json)./skillsitself does not survive a cold start, so a few seconds after a new session starts the bridge reinstalls every recorded skill in the background. Until that finishes (a few seconds per skill) a recorded skill may briefly be missing;list_skillsshows any that are still pending or whose reinstall failed. - OpenClaw picks a newly installed or removed skill up when it next refreshes its skill list (on file change, or at the latest at the next session start).
- Installs never bypass ClawHub's security review: a skill flagged as suspicious or malicious is refused with an explanation rather than installed. Tell the user why and do not retry with other flags.
- Only valid ClawHub skill names are accepted (letters, numbers, hyphens; no
@owner/prefix). - Pre-installed skills (
jina-reader,deep-research-pro,telegram-compose,transcript,task-decomposer) ship with the container image and cannot be uninstalled persistently.
