Copilot Studio — Authoring Tips

Practical tips and techniques learned from building agents with Copilot Studio. These enhance the current authoring experience or provide workarounds for platform limitations.

Only read the file relevant to the current task — do NOT read all files.

Date Context → date-context.md

Provides the current date to the orchestrator through agent instructions using Power FX ({Text(Today(),DateTimeFormat.LongDate)}). Enables accurate responses to date-related questions by giving the orchestrator explicit awareness of "today" for interpreting relative timeframes.

Read this tip when:

• Users ask date-relative questions ("What's next week?", "upcoming events", "recent announcements")
• The agent needs to filter time-sensitive knowledge sources
• Date interpretation is causing confusion or hallucinations
• The agent handles schedules, calendars, deadlines, or time-sensitive content

Dynamic Topic Redirect with Variable → Topic-redirect-withvariable.md

Uses a Switch() Power Fx expression inside a BeginDialog node to dynamically redirect to different topics based on a variable value. Replaces complex if/then/else condition chains with a single, maintainable YAML pattern.
