+# GitHub Copilot
+
+## Role
+
+- GitHub Copilot is a broadly used AI tool in the Fidelity workflow, especially when product-side code access and richer implementation context are available on the Fidelity machine.
+
+---
+
+## Stable Patterns
+
+- Use this tool when the local Fidelity-side product context is richer than what can be summarized indirectly in chat.
+- It is useful for investigation, code-oriented debugging, and implementation support when David can provide concrete build, file, and runtime details from the Fidelity development environment.
+- Tool output should still be checked against local evidence, reproduction results, and confirmed project context.
+
+---
+
+## Current Example
+
+- During the April 20, 2026 REST / LaunchDarkly investigation, Jeff specifically suggested using GitHub Copilot with more detailed local context from David's side.
+
+---
+
+## Risks
+
+- Do not assume the tool output is authoritative without checking it against local evidence.
+- Keep the tool's Fidelity-side access level and data visibility labeled as contextual rather than assumed workspace-wide.
