Required prerequisites

• I have read the documentation https://camel-ai.github.io/camel/camel.html.
• I have searched the Issue Tracker and Discussions that this hasn't already been reported. (+1 or comment there if it has.)
• Consider asking first in a Discussion.

What version of camel are you using?

0.2.84

System information

3.10.18 (main, Jul 11 2025, 22:25:58) [Clang 20.1.4 ] darwin
0.2.84

Problem description

there are two issues here,

1. run the examples under runtimes/code_execution_with_llm_guard.py, you will see the a log

2026-01-21 22:42:24,841 - camel.runtimes.llm_guard_runtime - ERROR - No tool call found in response.
2026-01-21 22:42:32,518 - camel.runtimes.llm_guard_runtime - ERROR - No tool call found in response.

if you check the agent response info using response.info, all the tool calls param have been disabled result={'error': 'Risk assessment failed. Disabling function.'} and the external_tool_call_requests is None, so one of the checks in the main code breaks.

2. the tools get overwritten in the example, so replace

runtime = LLMGuardRuntime(verbose=True).add(
    *CodeExecutionToolkit().get_tools()
)

tools = runtime.get_tools()

print("Tools:")
for tool in tools:
    print(tool.get_function_name())

with

toolkit = CodeExecutionToolkit(verbose=False)


runtime = LLMGuardRuntime(verbose=True).add(
    toolkit.get_tools()
)

tools = runtime.get_tools()

print("Tools:")
for tool in tools:
    print(tool.get_function_name())
