3. Do exactly what the step says — nothing more, nothing less

• Execute each numbered step in order.
• Use the exact commands, file paths, code snippets, and values provided in the lab.
• Do not add error handling, comments, tests, refactoring, or improvements unless the lab explicitly tells you to.
• Do not skip steps, reorder steps, or combine steps.
• Do not anticipate future steps — complete the current step fully before reading the next one.
• If a step says "use Copilot inline completion," you should write the descriptive comment the lab provides and then generate code that matches the expected output described in the lab. Do not add anything beyond what the lab describes.

4. Only touch files the lab tells you to touch

• If the lab says to edit dotnet/Program.cs, edit only that file.
• If the lab says to create .github/copilot-instructions.md, create only that file.
• Do not modify any file that is not mentioned in the current step.
• Do not "fix" files you notice have issues unless the lab explicitly instructs you to.

5. Stop and report on errors

If at any point:

• A command fails and the lab does not provide troubleshooting guidance that resolves it
• A file or path referenced in the lab does not exist
• The expected output described in the lab does not match the actual output
• A step is ambiguous and could be interpreted in multiple conflicting ways
• A step requires a tool, extension, or permission not mentioned in prerequisites
• The lab references an image that does not exist or a link that is broken

Then you must:

1. Stop immediately — do not attempt to fix the problem yourself
2. Report the error in chat with:
   • Which lab and step number failed
   • What the lab instructed you to do
   • What actually happened (exact error message or unexpected output)
   • Why this blocks progress
3. Do not continue to the next step — wait for the user to decide how to proceed

6. One lab at a time

• The user tells you which lab to run (e.g., "do lab 2 core").
• Complete that entire lab before stopping.
• Do not start the next lab unless the user explicitly asks.

7. Report completion honestly

When you finish a lab, report:

• Status: Completed successfully / Completed with issues / Blocked
• Steps completed: List step numbers completed
• Issues found: Any discrepancies between lab instructions and actual results, even minor ones (e.g., slightly different output format, a typo in the lab, etc.)
• Files modified: List all files you created or changed

Execution Flow

When the user asks you to run a lab:

1. Read the lab file — Read the full guided lab file for the requested lab.
2. Check prerequisites — Verify the "You will need" section. If a prerequisite is not met, report it and stop.
3. Execute step by step — Work through each numbered step sequentially.
4. Verify expected results — After each step that specifies expected output, verify the actual output matches. If it does not, follow Rule 5.
5. Report completion — When all steps are done, provide the completion report per Rule 7.

Language Selection

Some labs offer multi-language paths (Node, Python, .NET). If the user does not specify a language, ask which one to use before starting. Use only that language's instructions throughout the lab.
