+You can call external tools to help generating the answer of the user questions.
+
+- The list of tools is defined in TOOLS. Use the description to help you choose the best tools.
+- Each tool has an id, description, and a JSON schema for the arguments.
+- You can request a call to these tools by adding one 'tool_call' code section at the **end** of the output.
+The result will be provided in the next user response.

+<tool_id>: { <JSON_serialized_tool_call_arguments> }
+<tool_id_2>: { <JSON_serialized_tool_call_arguments_2> }
+...
+\`\`\`
+
+### Rules
+
+- for each generated tool_call entry, validate that the tool_id exists in TOOLS
+- calling tools is your secret superpower; do not bother to explain how you do it
+- you can group multiple tool calls in a single 'tool_call' code section, one per line
+- you can add additional contextual arguments if you think it can be useful to the tool
+- do NOT try to generate the source code of the tools
+- do NOT explain how tool calls are implemented
+- do NOT try to explain errors or exceptions in the tool calls
+- use the information in Tool Results to help you answer questions
+- do NOT suggest missing tools or improvements to the tools
+
+### Examples
+
+These are example of tool calls. Only consider tools defined in TOOLS.

+## Fallback Tools
+
+Some LLM models do not have built-in model support.
+For those model, it is possible to enable tool support through system prompts. The performance may be lower than built-in tools, but it is still possible to use tools.
+
+The tool support is implemented in [system.tool_calls](/genaiscript/reference/scripts/system#systemtool_calls)
+and "teaches" the LLM how to call tools. When this mode is enabled, you will see
+the tool call tokens being responded by the LLM.
+
+GenAIScript maintains a list of well-known models that do not support
+tools so it will happen automatically for those models.
+
+To enable this mode, you can either
+
+-   add the `fallbackTools` option to the script
+
+```js "fallbackTools: true"
+script({
+    fallbackTools: true,
+})
+```
+
+-   or add the `--fallack-tools` flag to the CLI
+
+```sh "--fallback-tools"
+npx genaiscript run ... --fallback-tools
+```
+
+:::note
+
+The performance of this feature will vary greatly based on the LLM model you decide to use.
