Can be set with `GITHUB_TOKEN` env var. | 15 | **API reference** | [Tools](/reference/tools-api) | 16 | **GitHub link** | https://github.com/deepset-ai/haystack-core-integrations/tree/main/integrations/github | 17 18 ## Overview 19 20 `GitHubPRCreatorTool` wraps the [`GitHubPRCreator`](../../pipeline-components/connectors/githubprcreator.mdx) component, providing a tool interface for use in agent workflows and tool-based pipelines. 21 22 The tool takes a GitHub issue URL and creates a pull request from your fork to the original repository, automatically linking it to the specified issue. It's designed to work with existing forks and assumes you have already made changes in a branch. 23 24 ### Parameters 25 26 - `name` is _optional_ and defaults to "pr_creator". Specifies the name of the tool. 27 - `description` is _optional_ and provides context to the LLM about what the tool does. 28 - `github_token` is _mandatory_ and must be a GitHub personal access token from the fork owner. The default setting uses the environment variable `GITHUB_TOKEN`. 29 - `raise_on_failure` is _optional_ and defaults to `True`. If False, errors are returned instead of raising exceptions. 30 31 ## Usage 32 33 Install the GitHub integration to use the `GitHubPRCreatorTool`: 34 35 ```shell 36 pip install github-haystack 37 ``` 38 39 :::note 40 Repository Placeholder 41 42 To run the following code snippets, you need to replace the `owner/repo` with your own GitHub repository name. 43 ::: 44 45 ### On its own 46 47 Basic usage to create a pull request: 48 49 ```python 50 from haystack_integrations.tools.github import GitHubPRCreatorTool 51 52 tool = GitHubPRCreatorTool() 53 result = tool.invoke( 54 issue_url="https://github.com/owner/repo/issues/123", 55 title="Fix issue #123", 56 body="This PR addresses issue #123 by implementing the requested changes.", 57 branch="fix-123", # Branch in your fork with the changes 58 base="main", # Branch in original repo to merge into 59 ) 60 61 print(result) 62 ``` 63 64 ```bash 65 {'result': 'Pull request #16 created successfully and linked to issue #4'} 66 ``` 67 68 ### With an Agent 69 70 You can use `GitHubPRCreatorTool` with the [Agent](../../pipeline-components/agents-1/agent.mdx) component. The Agent will automatically invoke the tool when needed to create pull requests. 71 72 ```python 73 from haystack.components.generators.chat import OpenAIChatGenerator 74 from haystack.dataclasses import ChatMessage 75 from haystack.components.agents import Agent 76 from haystack_integrations.tools.github import GitHubPRCreatorTool 77 78 pr_tool = GitHubPRCreatorTool(name="github_pr_creator") 79 80 agent = Agent( 81 chat_generator=OpenAIChatGenerator(), 82 tools=[pr_tool], 83 exit_conditions=["text"], 84 ) 85 86 agent.warm_up() 87 response = agent.run( 88 messages=[ 89 ChatMessage.from_user( 90 "Create a pull request for issue https://github.com/owner/repo/issues/4 with title 'Fix authentication bug' and empty body using my fix-4 branch and main as target branch", 91 ), 92 ], 93 ) 94 95 print(response["last_message"].text) 96 ``` 97 98 ```bash 99 The pull request titled "Fix authentication bug" has been created successfully and linked to issue [#123](https://github.com/owner/repo/issues/4). 100 ```
