Welcome to the MCS Labs Bug Bash! Your goal is to work through the labs and report any issues you find — broken steps, unclear instructions, missing images, incorrect information, or anything else that doesn't work as expected.
Open the MCS Labs Portal and navigate to the lab you are testing. Each lab page has a red Report Issue button in the top navigation bar.
While you are on the lab page where you found the issue, click the Report Issue button in the navigation bar.
This will open a new GitHub Issue with the lab name and a bug report template automatically pre-filled for you — including the title format and description fields.
The issue title will be pre-filled with the lab name in brackets (e.g., [mcs-multi-agent]). Type a short description of the issue after the lab name.
Title examples:
[mcs-multi-agent] Step 12 screenshot does not match current UI[core-concepts-agent-knowledge-tools] Broken link in Use Case #2[agent-builder-m365] Missing image after "Create new agent" step
The description will be pre-filled with a template. Fill in each field:
- Use case / step number — Where exactly did you encounter the issue?
- What happened — Describe what went wrong or what was confusing.
- What I expected — Describe what you think should have happened.
- Screenshots — Attach screenshots if applicable (drag and drop into the description field).
- Browser / environment — Note your browser and any relevant environment details if the issue is technical.
The Report Issue button pre-fills the lab label and Bug type for you. For the bug bash event, you must also add the bug bash label manually:
- On the right-hand side of the issue form, find Labels
- Click the gear icon next to Labels
- Search for and select
bug bash
Your issue should have the following set:
| Field | Required Value |
|---|---|
| Labels | bug bash and lab |
| Type | Bug |
Important: Issues without both the
bug bashandlablabels andBugtype will not be reviewed by the team during the bug bash.
Click the green Create button to submit your issue.
- Specific — Point to the exact lab, use case, and step number.
- Reproducible — Include the steps you followed so the team can reproduce the issue.
- Visual — Attach screenshots or screen recordings when possible.
- One issue per report — File separate issues for separate problems so each can be tracked independently.
If you have questions about the bug bash process or need help filing an issue, reach out to your event facilitator.
Thank you for helping us improve MCS Labs!
