Docs · Arkloop

Arkloop agents operate through tools — callable capabilities that let them read files, search the web, execute code, and more. Tools come from three sources: built-in tools available to every agent, MCP tools connected through external servers, and skill packages that extend the agent with specialized abilities.

Built-in Tools

Built-in tools are available to every agent without configuration. They are grouped by purpose.

File Operations

Tool	Purpose
`read`	Read file contents
`write_file`	Create or overwrite a file
`edit`	Apply targeted edits to an existing file
`glob`	Find files by name pattern
`grep`	Search file contents by pattern

Web

Tool	Providers
`web_search`	Basic / Tavily / Exa / SearXNG
`web_fetch`	Basic / Jina / Firecrawl

Search provider is configured in Settings → Providers. Fetch provider determines how web pages are retrieved and parsed.

Code Execution

Tool	Purpose
`sandbox`	Run code in an isolated execution environment

The sandbox provides a secure, ephemeral container for running user or agent-generated code. Output and errors are returned to the conversation.

Task Management

Tool	Purpose
`todo_write`	Create or update a task checklist
`enter_plan_mode`	Switch the agent to planning mode — outline steps before executing
`exit_plan_mode`	Return the agent to execution mode

Sub-agents

Tool	Purpose
`spawn_agent`	Delegate a sub-task to a child agent that runs in parallel

Sub-agents appear in the conversation as SubAgentBlocks, showing their status from spawn through completion.

User Interaction

Tool	Purpose
`askuser`	Agent asks for your input mid-task
`show_widget`	Render an interactive widget in the conversation

Other

Tool	Purpose
`summarize_thread`	Generate a summary of the current conversation
`arkloop_help`	Look up Arkloop product documentation and help articles

MCP Tools

MCP (Model Context Protocol) tools are third-party capabilities connected through MCP servers. They are not available by default — you add them through Settings → MCP.

Once an MCP server is configured, every tool it exposes becomes available to your agent automatically. The agent decides when to call them based on the conversation context.

See MCP Settings for configuration details.

Skills (Skill Packages)

Skills are installable tool packages that give your agent new capabilities. They bundle prompts, tools, and sometimes data into a single unit.

ClawHub Marketplace

Browse and install community-published skills from the ClawHub registry. Skills range from niche utilities to full workflow integrations.

Local Skills

Import skills from a GitHub repository or upload them directly from your file system.

Built-in Skills

Several skills ship with Arkloop:

Skill	Capability
`opencli`	OpenCLI command execution
`geogebra-drawing`	GeoGebra interactive math figures

Once a skill is installed, the agent automatically gains the corresponding tool capabilities. No manual wiring is needed.

Platform Management

The platform_manage tool is exclusive to the Platform Agent. It provides 40+ management actions covering projects, personas, threads, billing, and administrative operations. Regular agents do not have access to this tool.
