+# Copilot Instructions
+
+Read this file before starting any task. These rules apply to every task without exception.
+
+---
+
+## Environment
+
+- `/workspace` is the project root and a git repo
+- Use whatever language/runtime the project requires
+- Never install packages globally unless the task explicitly asks
+- Always verify installs work before reporting done
+
+---
+
+## Running Services
+
+- Check if a service manager exists (systemd, start.sh, etc.) before starting anything manually
+- Use `systemctl` if services are managed by systemd
+- Check health after starting: `curl http://localhost:<port>/health` or equivalent
+- Logs: `journalctl -u <service> -f` or check the project's log location
+
+---
+
+## Git
+
+- `/workspace` is a git repo — use git for file tracking
+- Use `git status --porcelain` to check changed files
+- Use `git diff HEAD` for full diffs
+- Never commit build artifacts, `__pycache__`, `*.pyc`, `node_modules`, or secrets
+
+---
+
+## Task Scope
+
+- Do exactly what the task describes — nothing more, nothing less
+- Do not add extra endpoints, files, dependencies, or features unless explicitly asked
+- Do not refactor code from previous tasks unless asked
+- If something seems wrong, flag it — don't silently fix it
+
+---
+
+## Verification
+
+- Always run the verify command specified in the task before reporting done
+- Report the exact output of the verify command
+- If verification fails, fix the issue first — do not report partial completion
+
+---
+
+## Reporting Back
+
+When a task is complete, report:
+1. What was created or changed (file list)
+2. The exact output of the verify command
+3. Any assumptions made or issues encountered
