What it does

Ag2 Use Builtin Tools is an agent skill from ag2ai/build-with-ag2. Wire AG2 beta's shipped tools into an Agent — both provider-native server-side tools (web search, web fetch, code execution, MCP, image generation, memory) and locally-executed common toolkits (filesystem, DuckDuckGo, Exa, Tavily, skills). Use when the user wants capabilities AG2 already ships rather than writing custom Python. For shell commands see ag2-shell-tool; for custom Python tools see ag2-add-custom-tool.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/builtin_tools_matrix.md`).

It sits in Productivity & Automation, covering Web search and Image generation. It works with Python, Model Context Protocol, Tavily and OpenAI. The repository describes itself as: Sample code and application showcases to get you going with AG2 (formally AutoGen). The licence is Apache-2.0.

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

Common toolkits (autogen.beta.tools — FilesystemToolkit, DuckDuckSearchTool, ExaToolkit, TavilySearchTool, SkillsToolkit) — regular Python…

What it can do on your machine

Read from SKILL.md and the folder at commit 29eeac3. 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).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- EXA_API_KEY
- TAVILY_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ag2 Use Builtin Tools loads about 1.3k tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 111 tokens; SKILL.md has 289 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~111
When it runs · the whole SKILL.md, loaded when a task matches: ~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~2.7k

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.

Use AG2 beta's built-in tools

When to use

Reach for this skill when the user wants to add a capability that AG2 already ships. Two families:

Provider-native tools (autogen.beta.tools — WebSearchTool, CodeExecutionTool, etc.) — executed server-side by Anthropic / OpenAI / Gemini. No Python implementation on your side.
Common toolkits (autogen.beta.tools — FilesystemToolkit, DuckDuckSearchTool, ExaToolkit, TavilySearchTool, SkillsToolkit) — regular Python that runs in your process and works with every provider.

For shell commands, use ag2-shell-tool (it's important enough to live in its own skill). For custom Python tools, use ag2-add-custom-tool.

60-second recipes

Web search (provider-native)

python

from autogen.beta import Agent
from autogen.beta.config import AnthropicConfig
from autogen.beta.tools import WebSearchTool, UserLocation

agent = Agent(
    "researcher",
    config=AnthropicConfig(model="claude-sonnet-4-6"),
    tools=[
        WebSearchTool(
            max_uses=5,
            user_location=UserLocation(country="US"),
            allowed_domains=["github.com", "pypi.org"],
            blocked_domains=["pinterest.com"],
        ),
    ],
)

Web fetch (Anthropic / Gemini only)

python

from autogen.beta.tools import WebFetchTool

tools = [WebFetchTool(max_uses=3, max_content_tokens=50000, citations=True)]

Code execution

python

from autogen.beta.tools import CodeExecutionTool

agent = Agent("analyst", config=config, tools=[CodeExecutionTool()])

MCP server integration

python

from autogen.beta.tools import MCPServerTool

tools = [
    MCPServerTool(
        server_url="https://mcp.example.com/sse",
        server_label="my-tools",
        allowed_tools=["search", "summarize"],
    ),
]

Image generation (OpenAI Responses only)

python

from autogen.beta.config import OpenAIResponsesConfig
from autogen.beta.tools import ImageGenerationTool

agent = Agent(
    "designer",
    config=OpenAIResponsesConfig(model="gpt-4.1"),
    tools=[ImageGenerationTool(quality="high", size="1024x1024", output_format="png")],
)
reply = await agent.ask("Generate a logo for a coffee shop.")
images: list[bytes] = reply.images

Filesystem (sandboxed, any provider)

python

from autogen.beta.tools import FilesystemToolkit

fs = FilesystemToolkit(base_path="/tmp/workspace")
agent = Agent("worker", config=config, tools=[fs])

base_path is enforced — ../../etc/passwd raises PermissionError. Use read_only=True to expose only read_file and find_files. For ephemeral workspaces use tempfile.TemporaryDirectory() rather than hardcoding /tmp.

Web search via DuckDuckGo (no API key)

python

from autogen.beta.tools import DuckDuckSearchTool
# requires: pip install ag2[ddgs]

tools = [DuckDuckSearchTool(max_results=10, region="us-en", safesearch="moderate")]

Exa neural search

python

import os
from autogen.beta.tools import ExaToolkit
# requires: pip install ag2[exa]

tools = [ExaToolkit(api_key=os.environ["EXA_API_KEY"])]

Each tool is exposed as a factory method (exa.search(), exa.find_similar(), exa.get_contents(), exa.answer()) so you can pass only what you need with per-call config.

Tavily search

python

import os
from autogen.beta.tools import TavilySearchTool
# requires: pip install ag2[tavily]

tools = [TavilySearchTool(
    api_key=os.environ["TAVILY_API_KEY"],
    search_depth="advanced",
    include_answer=True,
)]

Going deeper

Per-tool provider support, every parameter, version pinning — references/builtin_tools_matrix.md.
Source docs — website/docs/beta/tools/builtin_tools.mdx (provider-native), website/docs/beta/tools/common_toolkits.mdx (common toolkits — also covers SkillsToolkit and SkillSearchToolkit).
Toolkits authoring — website/docs/beta/tools/toolkits.mdx.

Common pitfalls

Mismatch between tool and provider — WebFetchTool raises with OpenAI; MemoryTool is Anthropic-only; ImageGenerationTool is OpenAI Responses only. Check references/builtin_tools_matrix.md first.
Anthropic tool versions default to older revisions — pin version="web_search_20260209" etc. when you need dynamic filtering on Opus 4.6 / Sonnet 4.6.
FilesystemToolkit paths are sandboxed — by design. Don't try to bypass the path-traversal guard; choose a wider base_path instead.
Toolkits and individual tools mix freely — tools=[fs, exa, my_custom_tool] is fine.
Optional dependency missing — DuckDuckSearchTool, ExaToolkit, TavilySearchTool need their ag2[<extra>] install. Without it you get a clear ImportError from the config-fallback layer, not a confusing crash.

Can I use Ag2 Use Builtin Tools in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ag2ai/build-with-ag2 --skill ag2-use-builtin-tools -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ag2-use-builtin-tools, .gemini/skills/ag2-use-builtin-tools, .github/skills/ag2-use-builtin-tools and .opencode/skills/ag2-use-builtin-tools in your project.

What does Ag2 Use Builtin Tools need to run?

Going by SKILL.md and its folder, Ag2 Use Builtin Tools needs credentials named EXA_API_KEY and TAVILY_API_KEY. Our summary lists: Python 3; A credential in EXA_API_KEY; A credential in TAVILY_API_KEY.

Does Ag2 Use Builtin Tools access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Ag2 Use Builtin Tools safe to install?
