Add auto-recompile workflow for agentic workflow markdown files

[Copilot]

Adds workflow to automatically recompile agentic workflow markdown files (.github/workflows/*.md) using gh aw compile and auto-merge changes on main branch.

Implementation

• Trigger: Push to main when .github/workflows/*.md files change
• Compilation: Installs gh-aw extension and recompiles all markdown workflow files to .lock.yml files using gh aw compile
• Change Detection: Detects new or modified .lock.yml files in the workflows directory
• PR flow: Creates PR via peter-evans/create-pull-request@v8.1.0, enables automerge via gh pr merge --squash --auto

Follows the established pattern from refresh_demos.yml and renovate.yml workflows:

• Uses ACTIONS_GITHUB_TOKEN with contents: read permissions for authentication
• 60s delay before automerge for API state propagation
• Resolves reviewers from .github/renovate.json
• OpenTelemetry instrumentation on job

Original prompt

Create a workflow that automatically recompile and open a pull request with auto merge when an agentic workflow file is touched on the main branch. look at other workflows and open prs with automerge the same way

@copilot u misunderstood. Im not wanting to recompile the copilot instructions, but rather agentic workflows that are in the workflows directory as md files. They need to be recompiled with gh aw compile when the markdown files are touched

Understood! I'll update the workflow to:

1. Trigger on changes to .github/workflows/*.md files (agentic workflow markdown files)
2. Recompile them using gh aw compile
3. Open a PR with the compiled .lock.yml files

Working on the fix now.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/github/gh-aw/releases/latest
  • Triggering command: /usr/bin/gh gh extension install github/gh-aw pipe�� (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Pull request overview

Adds a GitHub Actions workflow intended to automatically recompile “agentic workflow” Markdown files (.github/workflows/*.md) into generated workflow files and then open/auto-merge a PR with the results.

Changes:

• Introduces a new workflow triggered on pushes to main when .github/workflows/*.md (or the workflow itself) changes.
• Installs gh-aw and runs gh aw compile over workflow Markdown files.
• Opens a PR via peter-evans/create-pull-request and attempts to enable squash auto-merge via gh pr merge --auto.
