Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request integrates GitHub Agentic Workflows into the repository by introducing a new dispatcher agent. This agent is designed to intelligently route user requests to specialized prompts for various tasks, such as creating, updating, debugging, and upgrading workflows, as well as handling specific scenarios like Dependabot PRs and test coverage analysis. The changes also include necessary configuration for managing these agentic workflows.

Highlights

• New GitHub Agentic Workflows Agent: A new GitHub Agentic Workflows (gh-aw) dispatcher agent has been added, designed to route user requests to specialized prompts for various workflow-related tasks.
• Git Attributes Configuration: A .gitattributes entry was introduced to properly manage gh-aw lock files, marking them as generated and specifying an 'ours' merge strategy.
• Action Version Pinning: An actions-lock.json file was included to pin the github/gh-aw/actions/setup action to a specific version and SHA for consistency and security.

Changelog

• .gitattributes
  • Added a rule to treat github/workflows/*.lock.yml files as generated and to use the merge=ours strategy.
• .github/agents/agentic-workflows.agent.md
  • Added the definition for the GitHub Agentic Workflows dispatcher agent.
  • Detailed the agent's capabilities, including routing to specialized prompts for workflow creation, updates, debugging, upgrades, reporting, shared components, Dependabot PR fixes, and test coverage analysis.
  • Provided instructions on how to use the agent and a quick reference for gh aw CLI commands.
  • Outlined key features and important notes regarding gh-aw usage.
• .github/aw/actions-lock.json
  • Added a lock file to specify the exact version and SHA of the github/gh-aw/actions/setup action.

Code Review

This pull request introduces the foundation for using GitHub Agentic Workflows (gh-aw) by adding a central dispatcher agent configuration, a lock file for the setup action, and a git attribute for lock files. The changes are well-structured and clear. I've left a few minor suggestions to improve formatting consistency in the agent's markdown file.
