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.
