"The `Gitlab` toolkit contains tools that enable an LLM agent to interact with a gitlab repository. \n",
"The tool is a wrapper for the [python-gitlab](https://github.com/python-gitlab/python-gitlab) library. \n",
"\n",
"## Quickstart\n",
"1. Install the python-gitlab library\n",
"2. Create a Gitlab personal access token\n",
"3. Set your environmental variables\n",
"4. Pass the tools to your agent with `toolkit.get_tools()`\n",
"\n",
"Each of these steps will be explained in greate detail below.\n",
"\n",
"1. **Get Issues**- fetches issues from the repository.\n",
"\n",
"2. **Get Issue**- feteches details about a specific issue.\n",
"\n",
"3. **Comment on Issue**- posts a comment on a specific issue.\n",
"\n",
"4. **Create Pull Request**- creates a pull request from the bot's working branch to the base branch.\n",
"\n",
"5. **Create File**- creates a new file in the repository.\n",
"\n",
"6. **Read File**- reads a file from the repository.\n",
"\n",
"7. **Update File**- updates a file in the repository.\n",

"* **GITLAB_PERSONAL_ACCESS_TOKEN**- The personal access token you created in the last step\n",
"* **GITLAB_REPOSITORY**- The name of the Gitlab repository you want your bot to act upon. Must follow the format {username}/{repo-name}.\n",
