Get information about the current git repository: current branch, default branch, remote URL, and detected platform (github/gitlab).

List all available Pull Request / Merge Request templates found in the repository.

Gather all the data needed to create a Pull Request or Merge Request:

• Git diff between the current branch and the default branch

• Commit log

• List of changed files

• PR/MR template (if one exists in the repo)

• Repository metadata (platform, owner, repo)

The returned data is intended for the LLM to use when composing the PR/MR title and body. If a template is found, the LLM should fill it in. Otherwise, the LLM should generate appropriate content based on the diff and commit log.

Publish a Pull Request (GitHub) or Merge Request (GitLab) with the given title and body. The platform is auto-detected from the git remote URL. Auth tokens are read from environment variables: GITHUB_TOKEN or GITLAB_TOKEN.
