Built-in Tools

Huginn’s agentic loop has access to a suite of built-in tools for autonomous operation.

File Operations

Tool	Description
`read_file`	Read a file’s contents
`write_file`	Write content to a file (with diff preview)
`edit_file`	Apply targeted edits to an existing file
`list_dir`	List directory contents
`search_files`	Search file contents with grep-like patterns

Tool	Description
`bash`	Execute shell commands (configurable timeout)
`run_tests`	Run your test suite (e.g. `go test ./...`, `pytest`, `make test`)

Control which tools Huginn can use in ~/.huginn/config.json:

{
  "disallowed_tools": ["bash", "git_commit"]
}

Or use an allowlist:

{
  "allowed_tools": ["read_file", "search_files", "write_file"]
}
