 This document guides you on creating custom tools for the LLM Functions framework in Bash, JavaScript, and Python.
 
-## Definition via Comments
+## Defining Tool Parameters
 
-The key to defining the parameters your tool accepts is through specially formatted comments within your tool's source code.
+To define the parameters that your tool accepts, you will use specially formatted comments within your tool's source code.
-The `Argcfile.sh` uses these comments to automatically generate the function declaration used by the LLM.

+## Common tools
 
-## Quickly create tools
+Common tools can be found in `tools/<tool-name>.{sh,js,py}`. Each script defines a single tool.
+
+## Agent tools
+
+Agents can possess their own toolset scripts located under `agents/<agent-name>/tools.{sh,js,py}`, which can contain multiple tool functions.
+
+The following is an example of git agent:
+
+### Bash
+
+```sh file=agents/git/tools.sh
+# @cmd Shows the working tree status
+git_status() {
+    # ... your bash code ...
+}
+
+# @cmd Shows differences between branches or commits
+# @option --target!   Shows differences between branches or commits 
+git_diff() {
+    # ... your bash code ...
+}
+
+eval "$(argc --argc-eval "$0" "$@")"
+```
+
+> In `tools/<tool-name>.sh`, we use the `@describe` comment tag and a single `main` function, since it has only one function and no subcommands.
+> In `agent/<agent-name>/tools.sh`, we use the `@cmd` comment tag and named functions, since it can have multiple tool functions.
+
+### JavaScript
+
+```js file=agents/git/tools.js
+/**
+ * Shows the working tree status
+ */
+exports.git_status = function() {
+  // ... your JavaScript code ...
+}
+
+/**
+ * Shows differences between branches or commits
+ * @typedef {Object} Args
+ * @property {string} target - Shows differences between branches or commits 
+ * @param {Args} args
+ */
+exports.git_diff = function() {
+  // ... your JavaScript code ...
+}
+```
+
+### Python
+
+```py file=agents/git/tools.py
+def git_status():
+    """Shows the working tree status"""
+    # ... your Python code ...
+
+
+def git_diff(target: str):
