+# Copilot Prompt Template
+
+Generate a prompt to send to GitHub Copilot on the Fidelity development machine.
+
+The prompt should be self-contained because Copilot will not have this workspace's memory unless the prompt includes it.
+
+Requirements:
+
+- Use precise senior-engineer language
+- Include only relevant context
+- Include Jira ID and approved title when available
+- Tell Copilot what to inspect before changing code
+- Make constraints explicit
+- Specify whether the desired result is:
+  - investigation
+  - implementation plan
+  - code change
+  - review
+  - test strategy
+  - PR/story text
+- Include expected output format
+- Include validation requirements
+- Avoid overloading the prompt with unrelated workspace history
+
+Default output format:
+
+```text
+Role:
+
+Project context:
+
+Task:
+
+Relevant ticket/context:
+
+Inspect:
+
+Constraints:
+
+Expected output:
+
+Validation:
