What it does
Tool Creator is an agent skill from AgentTeam-TaichuAI/ScienceClaw. Create new tools or upgrade existing tools for the agent. MANDATORY: Use this skill whenever the user wants to create a custom tool, convert a script into a reusable tool, write a new tool function, upgrade or modify an existing tool, test and improve a tool in the sandbox, or asks things like 'make a tool for X', 'create a tool that does Y', 'improve the X tool', 'upgrade my tool', 'turn this script into a tool'. Even if the user doesn't use the word 'tool' explicitly, trigger this if they want to add a new…
Its SKILL.md is about 4.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in AI & LLM Engineering, covering Building AI agents. It works with LangChain. The repository describes itself as: ScienceClaw is a personal research assistant built with LangChain DeepAgents and AIO Sandbox infrastructure, adopting a completely new architecture beyond OpenClaw. It offers…
When your agent uses it
- The user wants to create a custom tool
- Convert a script into a reusable tool
- Write a new tool function
- Modify an existing tool
Example prompts
- “make a tool for X”
- “create a tool that does Y”
- “improve the X tool”
- “/tool-creator”
Requirements
- Python 3
- Docker
Workflow steps
10 steps, taken from the step headings in SKILL.md.
- Understand Requirements
- Write the Tool (as @tool from the start)
- Test the @tool in Sandbox
- Review with User
- Save the Tool (copy tested file, do NOT rewrite)
- Identify the Tool
- Copy to Workspace for Development
- Modify and Test
- Side-by-Side Comparison
- Propose Replacement (copy tested file, do NOT rewrite)
What it can do on your machine
Read from SKILL.md and the folder at commit 3817e56. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are python and bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
docs.newapi.com
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
Tool Creator loads about 4.7k tokens when it runs. Until then it costs about 147 tokens; SKILL.md has 1,896 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,896 words (~4,668 tokens).
“A skill for creating new agent tools and upgrading existing ones.”
