Can be set with `GITHUB_TOKEN` env var. | 17 | **API reference** | [Tools](/reference/tools-api) | 18 | **GitHub link** | https://github.com/deepset-ai/haystack-core-integrations/tree/main/integrations/github | 19 20 </div> 21 22 ## Overview 23 24 `GitHubPRCreatorTool` wraps the [`GitHubPRCreator`](../../pipeline-components/connectors/githubprcreator.mdx) component, providing a tool interface for use in agent workflows and tool-based pipelines. 25 26 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. 27 28 ### Parameters 29 30 - `name` is _optional_ and defaults to "pr_creator". Specifies the name of the tool. 31 - `description` is _optional_ and provides context to the LLM about what the tool does. 32 - `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`. 33 - `raise_on_failure` is _optional_ and defaults to `True`. If False, errors are returned instead of raising exceptions. 34 35 ## Usage 36 37 Install the GitHub integration to use the `GitHubPRCreatorTool`: 38 39 ```shell 40 pip install github-haystack 41 ``` 42 43 :::info[Repository Placeholder] 44 45 To run the following code snippets, you need to replace the `owner/repo` with your own GitHub repository name. 46 ::: 47 48 ### On its own 49 50 Basic usage to create a pull request: 51 52 ```python 53 from haystack_integrations.tools.github import GitHubPRCreatorTool 54 55 tool = GitHubPRCreatorTool() 56 result = tool.invoke( 57 issue_url="https://github.com/owner/repo/issues/123", 58 title="Fix issue #123", 59 body="This PR addresses issue #123 by implementing the requested changes.", 60 branch="fix-123", # Branch in your fork with the changes 61 base="main", # Branch in original repo to merge into 62 ) 63 64 print(result) 65 ``` 66 67 ```bash 68 {'result': 'Pull request #16 created successfully and linked to issue #4'} 69 ``` 70 71 ### With an Agent 72 73 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. 74 75 ```python 76 from haystack.components.generators.chat import OpenAIChatGenerator 77 from haystack.dataclasses import ChatMessage 78 from haystack.components.agents import Agent 79 from haystack_integrations.tools.github import GitHubPRCreatorTool 80 81 pr_tool = GitHubPRCreatorTool(name="github_pr_creator") 82 83 agent = Agent( 84 chat_generator=OpenAIChatGenerator(), 85 tools=[pr_tool], 86 exit_conditions=["text"], 87 ) 88 89 response = agent.run( 90 messages=[ 91 ChatMessage.from_user( 92 "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", 93 ), 94 ], 95 ) 96 97 print(response["last_message"].text) 98 ``` 99 100 ```bash 101 The pull request titled "Fix authentication bug" has been created successfully and linked to issue [#123](https://github.com/owner/repo/issues/4). 102 ```
