+# Copilot Coding Agent Configuration
+
+This repository includes a minimal opt-in configuration and CI workflow to allow the GitHub Copilot coding agent to open and validate PRs.
+
+- .copilot-agent.yml: opt-in config for automated agents
+- .github/workflows/dotnetcore.yml: CI runs on PRs touching the solution, source, or tests to validate changes
+- AGENTS.yml: general information for this project
+
+Maintainers can adjust the allowed paths or disable the agent by editing or removing .copilot-agent.yml.
+
+Notes:
+- Do not change any other files in the repository.
+- If build/test paths are different, update the workflow accordingly; this workflow targets SharpCompress.sln and the SharpCompress.Tests test project.
