axio-tools-local

Core filesystem and shell tool handlers for axio.

Gives your agent the ability to read, write, and patch files, run shell commands, execute Python snippets, and browse directory trees — the essential toolkit for a coding assistant.

Tools

Tool	Entry point	Description
Shell	shell	Run any shell command with configurable timeout, cwd, and stdin
RunPython	run_python	Execute a Python snippet in a subprocess
ReadFile	read_file	Read a file, optionally with line range
WriteFile	write_file	Write or overwrite a file
PatchFile	patch_file	Apply a targeted string replacement (old → new)
ListFiles	list_files	List files matching a glob pattern

Installation

pip install axio-tools-local

Usage

Standalone (without TUI)

from axio import Agent
from axio.context import MemoryContextStore
from axio_transport_openai import OpenAITransport
from axio_tools_local.shell import Shell
from axio_tools_local.read_file import ReadFile
from axio_tools_local.write_file import WriteFile
from axio_tools_local.list_files import ListFiles
from axio.tool import Tool

tools = [
    Tool(name="shell",      description=Shell.__doc__ or "",     handler=Shell),
    Tool(name="read_file",  description=ReadFile.__doc__ or "",  handler=ReadFile),
    Tool(name="write_file", description=WriteFile.__doc__ or "", handler=WriteFile),
    Tool(name="list_files", description=ListFiles.__doc__ or "", handler=ListFiles),
]

agent = Agent(
    system="You are a coding assistant with access to the local filesystem.",
    tools=tools,
    transport=OpenAITransport(api_key="sk-...", model="gpt-4o"),
)

Via plugin (with axio-tui)

pip install "axio-tui[local]"
uv run axio   # Shell, ReadFile, WriteFile, PatchFile, ListFiles, RunPython appear automatically

Tool details

Shell

Shell(command="git log --oneline -5", cwd="/path/to/repo", timeout=30)
Shell(command="python -m pytest", stdin=None)

Parameters: command: str, timeout: int = 5, cwd: str = ".", stdin: str | None = None

PatchFile

Applies an exact string replacement — safe for surgical edits without rewriting the whole file:

PatchFile(
    file_path="src/main.py",
    old_string="def foo():",
    new_string="def foo(x: int) -> int:",
)

ListFiles

ListFiles(pattern="src/**/*.py")
ListFiles(pattern="tests/test_*.py")

RunPython

RunPython(code="import sys; print(sys.version)")
