Topic coverage for Copilot practice
| Area | What to practise |
|---|---|
| Responsible AI | safe use, limitations, review discipline, attribution awareness, and human oversight |
| Copilot features | chat, completions, explanations, refactoring, tests, pull requests, and plan-specific capabilities |
| Data and architecture | how context is used, privacy boundaries, content exclusions, and organizational safeguards |
| Prompt and context crafting | clear intent, constraints, examples, repository context, and iterative refinement |
| Developer productivity | quality improvement, testing, documentation, debugging, and workflow acceleration |
Copilot safe-use loop
Copilot questions usually reward the workflow where the developer frames the task, gives relevant context, reviews output critically, tests it, and keeps sensitive data out of prompts.

Intent["State intent"] --> Context["Add relevant context"]
Context --> Prompt["Ask with constraints"]
Prompt --> Review["Review generated output"]
Review --> Test["Test and validate"]
Test --> Refine["Refine prompt or code"]
Refine --> Review
Review --> Secure["Check security, privacy, and licensing risk"]
Secure --> Commit["Commit only reviewed work"]
Copilot exhibit patterns to practise
GH-300-style questions can include small exhibits. Use them to decide what context Copilot has, what policy applies, and what a responsible next step looks like. The best exhibit is usually a short prompt, chat exchange, policy table, audit line, or selected-code description rather than a large diagram.
| Exhibit type | What to look for |
|---|---|
| Prompt snippet | Missing constraints, unclear goal, sensitive data, or absent repository context |
| Copilot Chat exchange | Whether the developer should refine, verify, test, or reject the answer |
| Selected-code context | Whether Copilot has enough local context to make a useful suggestion |
| Organization policy excerpt | Content exclusions, allowed features, review requirements, and data handling |
| Audit log entry | Which user, repository, policy, or subscription event needs review |
| Pull request summary | Whether Copilot is helping review focus without replacing required reviewers |
Example prompt exhibit:
Refactor this payment helper to make it easier to test.
Keep the public function name unchanged.
Do not change currency rounding behavior.
Use pytest examples for the boundary cases.
Example chat exhibit:
Developer: Explain why this authentication middleware rejects valid tokens.
Copilot: The token may be expired or the signing key may be different.
Developer: The token is not expired. The failing test uses the staging JWKS URL.
Best next step: refine the prompt with the environment, failing test, and selected middleware code.
Example policy exhibit:
| Policy setting | Meaning for the question |
|---|---|
Content exclusions enabled for /contracts/ | Do not rely on excluded files for suggestions |
| Public code suggestions restricted | Review generated snippets for licensing and source-risk concerns |
| Copilot Chat allowed in private repositories | Still avoid secrets, customer data, and confidential business data in prompts |
| Required pull request review remains enabled | Copilot summaries do not replace human approval |
Example audit exhibit:
2026-04-24T15:12:04Z copilot.policy.update org=acme-inc actor=repo-admin
setting=content_exclusions path=/contracts/** repositories=engineering-platform
GH-300 decision filters
Use these filters when a Copilot answer sounds productive but unsafe:
- Context quality: check whether the prompt includes the selected code, repository context, constraints, examples, and expected output.
- Human review: treat Copilot output as a draft that must be read, tested, and checked against requirements.
- Privacy boundary: avoid secrets, regulated data, customer data, unreleased business plans, and excluded paths in prompts or context.
- Feature fit: distinguish completions, Chat, pull request summaries, code review support, CLI help, and organizational policy controls.
- Governance signal: apply content exclusions, policy settings, audit events, subscription controls, and safeguards at the right org or repo scope.
Final 7-day GH-300 practice sequence
| Day | Practice focus |
|---|---|
| 7 | Open the web app for a timed mixed set, then use the public diagnostic page if you need to tag misses by prompt, feature, policy, privacy, or productivity. |
| 6 | Drill responsible AI, output review, testing discipline, limitations, and safe developer behavior. |
| 5 | Drill Copilot features, chat workflows, code completion, pull request support, and plan-specific capability choices. |
| 4 | Drill context crafting, selected code, prompt constraints, examples, and iterative refinement. |
| 3 | Drill privacy, content exclusions, organizational policies, audit signals, and safeguard settings. |
| 2 | Complete a timed mixed set and explain whether each miss was a context, feature, policy, or review issue. |
| 1 | Review weak exhibit types; avoid treating Copilot as an autopilot or approval system. |
When GH-300 practice is enough
If several unseen mixed attempts are above roughly 75% and you can explain the responsible-use, context, privacy, or feature-selection reason behind your answers, you are likely ready. Additional drilling should improve Copilot judgment, not make you memorize policy wording.
