+### Tools: Prompt Loader
+
+L2M2 provides an optional prompt-loading utility that's useful for loading prompts with variables from a file. Usage is simple:
+
+_prompt.txt_
+
+```
+Your name is {{name}} and you are a {{profession}}.
+```
+
+```python
+# example_prompt_loader.py
+
+from l2m2.tools import PromptLoader
+
+loader = PromptLoader()
+prompt = loader.load_prompt(
+    prompt_file="prompt.txt",
+    variables={"name": "Pierce", "profession": "software engineer"},
+)
+print(prompt)
+```
+
+```
+>> python3 example_prompt_loader.py
+
+Your name is Pierce and you are a software engineer.
+```
+
+You can also optionally specify a prompt directory or customize the variable delimiters if needed.
+
+_path/to/prompts/prompt.txt_
+
+```
+Your name is <<name>> and you are a <<profession>>.
+```
+
+```python
+# example_prompt_loader.py
+
+from l2m2.tools import PromptLoader
+
+loader = PromptLoader(
+    prompts_base_dir="path/to/prompts",
+    variable_delimiters=("<<", ">>"),
+)
+prompt = loader.load_prompt(
+    prompt_file="prompt.txt",
+    variables={"name": "Pierce", "profession": "software engineer"},
+)
+print(prompt)
+```
+
+```
+>> python3 example_prompt_loader.py
