Task 6.2: Apply safeguards and troubleshoot

• ACode references are only produced on the Copilot Pro+ plan

  Incorrect

  Code references are not tied to Pro+; the setting itself is inherited here.

• BShe must first enable the setting in VS Code's settings.json

  Incorrect

  The setting lives in her GitHub settings, not in the editor.

• CHer setting is inherited from her organization or enterprise, so she can't set it

  Correct

  Members assigned a seat through an organization on GitHub Enterprise Cloud inherit the setting for suggestions matching public code.

• DThe setting only appears after she opts out of model training

  Incorrect

  The two settings are independent.

Personal Copilot settings include an option to allow or block suggestions that match public code. If you are a member of an organization on GitHub Enterprise Cloud and your seat is assigned through that organization, you can't configure this in your personal settings; it is inherited from your organization or enterprise.

• AIn VS Code, run Developer: Reload Window from the Command Palette

  Correct

  Reloading the window reloads the content exclusion settings in VS Code.

• BSign out of GitHub on GitHub.com and sign back in

  Incorrect

  Signing in again on the website is not a documented way to refresh exclusion settings in an IDE.

• CDelete the .github directory from the repository and clone the repository again

  Incorrect

  Exclusions come from settings on GitHub, not from repository files.

• DIn a JetBrains IDE, close and reopen the application

  Correct

  For JetBrains IDEs and Visual Studio, closing and reopening the application reloads the settings.

• ERun copilot --cloud in a terminal in the repository

  Incorrect

  That starts a cloud-sandboxed CLI session; it doesn't refresh IDE settings.

After you add or change content exclusions, it can take up to 30 minutes for them to take effect in IDEs that have already loaded the settings. To apply them now, reload the settings: in VS Code run Developer: Reload Window, and in JetBrains IDEs and Visual Studio close and reopen the application. Vim/Neovim fetches exclusions each time a file is opened.

• AIn a notification that appears before the suggestion is accepted

  Incorrect

  Matches for inline suggestions are logged after acceptance, not shown as a pre-accept notification.

• BIn the Problems panel, as a warning on the line that was inserted

  Incorrect

  The Problems panel is not where code references are logged.

• CIn the repository's Security tab on GitHub

  Incorrect

  Code references are recorded locally in the editor's log.

• DIn the Output window, under GitHub Copilot Log (Code References)

  Correct

  In VS Code, select GitHub Copilot Log (Code References) in the Output window; accepted suggestions that match public code add an entry with license and URL.

In VS Code, open View > Output and choose GitHub Copilot Log (Code References). When you accept an inline suggestion that matches code in a public GitHub repository, an entry is added with the file, location, code extract, license (or unknown) and the URL of the matching file.

• AIn the repository's Settings > Copilot > Content exclusion page

  Incorrect

  Content exclusion controls which files Copilot reads, not public code matches.

• BIn VS Code's settings.json under github.copilot.enable

  Incorrect

  That setting enables Copilot per language.

• CIn her GitHub Copilot settings: Suggestions matching public code > Block

  Correct

  In Copilot settings, select Block in the dropdown for Suggestions matching public code.

• DIn the Copilot CLI with /settings publicCode off

  Incorrect

  Public code matching is a GitHub account setting, not a CLI setting.

Personal Copilot settings on GitHub include an option to allow or block suggestions matching public code: click your profile picture, then Copilot settings, and choose Allow or Block next to Suggestions matching public code. With Block, suggestions plus about 150 characters of surrounding code are checked against public code, and matches or near matches are not shown.

• AIn the Problems tool window, under Copilot warnings

  Incorrect

  Code references are not shown in the Problems window.

• BIn the IDE log file, searching for [Public Code References]

  Correct

  Open Help > Show Log in Finder/Explorer, open the log (idea.log for IntelliJ IDEA) and search for [Public Code References].

• CIn the repository's Insights tab on GitHub

  Incorrect

  Code references for inline suggestions are logged locally.

• DIn the Copilot Chat panel, which lists every accepted suggestion

  Incorrect

  Chat lists matches for its own responses, not every inline suggestion.

In JetBrains IDEs, code references for inline suggestions are written to the IDE log. Select Help > Show Log in Finder/Explorer, open the log file (idea.log for IntelliJ IDEA) and search for [Public Code References]. Entries show the time, the file and position, and each match with its license (or NOASSERTION) and URL.

• AA content exclusion setting covers the file

  Correct

  When a file is affected by content exclusion, the status bar icon has a diagonal line; hovering shows which settings applied it.

• BHer monthly AI credits are exhausted

  Incorrect

  Completions aren't billed in AI credits, and the icon means something else.

• CThe file's language is not supported by Copilot

  Incorrect

  The diagonal-line icon indicates an exclusion setting.

• DCopilot is downloading a model update

  Incorrect

  The icon doesn't indicate downloads.

With a Copilot Business or Enterprise license, you may not see inline suggestions in some files because they are excluded from Copilot by a repository administrator or organization owner. If content exclusion applies to a file, the Copilot icon in the status bar has a diagonal line through it; hover over it to see which settings applied the restriction.

• ANext edit suggestions being turned off

  Incorrect

  Next edit suggestions don't stop ordinary inline suggestions.

• BThe Bing web search setting being disabled

  Incorrect

  Web search only affects Copilot Chat answers.

• CTelemetry being disabled in the IDE

  Incorrect

  Telemetry affects activity reporting, not suggestions.

• DDuplication detection blocking public-code matches

  Correct

  If you receive limited or no suggestions, you may have duplication detection enabled, which blocks matches with public code.

The code suggestions guide notes that if you receive limited or no suggestions from Copilot, you may have duplication detection enabled. When suggestions matching public code are blocked, matches or near matches are not shown, which is more likely for common code patterns.
