Built-in Tools

Ruri's AI isn't just a chatbot — it can take action on your behalf. Built-in tools let the AI read files, write code, search the web, and even run commands on your system.

What Can the AI Do?

Here's a quick overview of the tools available to the AI:

Tool	What It Does
Read File	Read the contents of any file
Write File	Create or overwrite files
Create File	Create a brand new file with content
Edit File	Make precise edits to existing files
List Directory	Browse folders and see what's inside
Search Files	Find files by name or search within file contents
Bash	Run shell commands (requires Computer Use)
Web Search	Search the web for up-to-date information

Practical Examples

Working with Code

You can ask the AI to help with your code projects, and it will use tools to get the job done:

• "Read my main.rs file and explain what it does" — The AI uses Read File to inspect your code
• "Fix the typo in config.toml on line 42" — The AI uses Edit File to make a precise change
• "Create a new Python script that processes CSV files" — The AI uses Create File to write a brand new file
• "Show me what's in my project directory" — The AI uses List Directory to browse your folders
• "Find all files that import axios" — The AI uses Search Files to scan your project

Searching the Web

• "What's the latest version of React?" — The AI uses Web Search to find current information
• "Look up how to configure nginx as a reverse proxy" — The AI searches the web and gives you a summary

信息

Web Search must be enabled in your Config Profile and requires a search provider to be configured.

Running Commands

• "Run my test suite" — The AI uses Bash to execute your tests
• "Install the dependencies for this project" — The AI runs npm install or cargo build
• "Check my disk usage" — The AI runs df -h and explains the output

警告

Command execution requires Computer Use to be enabled, and the AI can run any command your system allows. See Computer Use for safety details.

When the AI Uses Tools

You don't need to tell the AI which tool to use — it decides automatically based on your request. Here's what the experience looks like:

1. You send a message — For example, "What does my package.json look like?"
2. The AI reads the file — You'll see a tool call appear in the chat, showing that the AI is reading package.json
3. The AI responds — It shares the file contents and may add context or suggestions

The AI might use multiple tools in sequence to answer your question. For example, if you ask "Are there any bugs in my code?", it might:

1. List your directory to find source files
2. Read each file to understand the code
3. Search for common bug patterns
4. Respond with its findings

提示

You can see every tool call the AI makes right in the conversation. This gives you full visibility into what the AI is doing on your behalf.

Controlling Tool Access

By default, the AI has access to all file tools. You can control what's available:

• Web Search — Enable or disable in your Config Profile
• Bash / Command Execution — Enable through Computer Use settings
• Per-skill restrictions — When creating Skills, you can limit which tools the AI can use for that specific skill

Tips

• Be specific — Instead of "help with my code", say "read my src/main.rs and find potential bugs". The AI will know exactly which tools to use.
• Review tool calls — Always check what the AI is doing, especially when it writes files or runs commands
• Use Computer Use wisely — Only enable command execution when you need it. Keep it off for simple chat sessions.
