+# Below is the complete list of tools for convenience.
+# To make sure you have the latest list of tools, and to view their descriptions, 
+# execute `uv run scripts/print_tool_overview.py`.
+#
+#  * `activate_project`: Activates a project based on the project name or path.
+#  * `check_onboarding_performed`: Checks whether project onboarding was already performed.
+#  * `create_text_file`: Creates/overwrites a file in the project directory.
+#  * `delete_memory`: Delete a memory file. Should only happen if a user asks for it explicitly,
+#       for example by saying that the information retrieved from a memory file is no longer correct
+#       or no longer relevant for the project.
+#  * `edit_memory`: Replaces content matching a regular expression in a memory.
+#  * `execute_shell_command`: Executes a shell command.
+#  * `find_file`: Finds files in the given relative paths
+#  * `find_referencing_symbols`: Finds symbols that reference the given symbol using the language server backend
+#  * `find_symbol`: Performs a global (or local) search using the language server backend.
+#  * `get_current_config`: Prints the current configuration of the agent, including the active and available projects, tools, contexts, and modes.
+#  * `get_symbols_overview`: Gets an overview of the top-level symbols defined in a given file.
+#  * `initial_instructions`: Provides instructions Serena usage (i.e. the 'Serena Instructions Manual')
+#       for clients that do not read the initial instructions when the MCP server is connected.
+#  * `insert_after_symbol`: Inserts content after the end of the definition of a given symbol.
+#  * `insert_before_symbol`: Inserts content before the beginning of the definition of a given symbol.
+#  * `list_dir`: Lists files and directories in the given directory (optionally with recursion).
+#  * `list_memories`: List available memories. Any memory can be read using the `read_memory` tool.
+#  * `onboarding`: Performs onboarding (identifying the project structure and essential tasks, e.g. for testing or building).
+#  * `read_file`: Reads a file within the project directory.
+#  * `read_memory`: Read the content of a memory file. This tool should only be used if the information
+#       is relevant to the current task. You can infer whether the information
+#       is relevant from the memory file name.
+#       You should not read the same memory file multiple times in the same conversation.
+#  * `rename_memory`: Renames or moves a memory. Moving between project and global scope is supported
+#       (e.g., renaming "global/foo" to "bar" moves it from global to project scope).
+#  * `rename_symbol`: Renames a symbol throughout the codebase using language server refactoring capabilities.
+#       For JB, we use a separate tool.
+#  * `replace_content`: Replaces content in a file (optionally using regular expressions).
+#  * `replace_symbol_body`: Replaces the full definition of a symbol using the language server backend.
+#  * `safe_delete_symbol`:
+#  * `search_for_pattern`: Performs a search for a pattern in the project.
+#  * `write_memory`: Write some information (utf-8-encoded) about this project that can be useful for future tasks to a memory in md format.
+#       The memory name should be meaningful.
