+# Repository Copilot customizations
+
+The reusable bundle was promoted from DriverAutomationTool and originally
+installed from [github/awesome-copilot](https://github.com/github/awesome-copilot)
+at commit `82701c24b99488536ca399ff4789a458b7a05db7`. Its MIT license is
+retained in [AWESOME-COPILOT-LICENSE](AWESOME-COPILOT-LICENSE).
+
+| Customization | Location | Purpose |
+|---|---|---|
+| Repository guidance | [Copilot instructions](copilot-instructions.md) | Project architecture, safety boundaries, and validation contract |
+| Terminal helper | [Agent profile](agents/terminal-helper.agent.md) | PowerShell and Bash command assistance |
+| Microsoft Learn contributor | [Agent profile](agents/microsoft_learn_contributor.agent.md) | Documentation structure, accessibility, and Microsoft writing style |
+| PowerShell guidance | [Instructions](instructions/powershell.instructions.md) | Applies to `*.ps1` and `*.psm1` |
+| Pester 6 guidance | [Instructions](instructions/powershell-pester-6.instructions.md) | Applies to `*.Tests.ps1` |
+| Copilot PR autopilot | [Skill](skills/copilot-pr-autopilot/SKILL.md) | Explicitly requested PR review and feedback loops |
+
+The imported bundle contains 29 files. Its seven PowerShell scripts retain the
+UTF-8 byte-order mark required for reliable Windows PowerShell 5.1 parsing.
+Installing these files does not start an agent, execute a skill, or change the
+application. Preserve Windows PowerShell 5.1 compatibility and existing public
+contracts when applying general guidance.
+
+The PR skill requires an explicitly selected pull request, authenticated GitHub
+CLI, and the permissions documented in the skill. It can commit, push, reply,
+and resolve review threads when invoked; installation performs none of those
+operations.
