Autofix provides you with targeted recommendations to help you fix code scanning alerts so you can avoid introducing new security vulnerabilities. The potential fixes are generated automatically by large language models (LLMs) using data from the codebase and from code scanning analysis.
How autofix works
Autofix translates the description and location of a code scanning alert into code changes that may fix it. It interfaces with the large language model GPT-5.3-Codex from OpenAI, which has sufficient generative capabilities to produce both suggested fixes in code and explanatory text for those fixes.
There are two ways to get a fix for an alert: agentic autofix and 코파일럿 자동 수정. If Copilot 클라우드 에이전트 is available in a repository, assigning an alert uses agentic autofix instead of 코파일럿 자동 수정.
Agentic autofix
참고
This feature is currently in public preview and is subject to change.
Assign a code scanning alert to Copilot to have it resolve the alert for you. Assigning an alert starts an agent session: Copilot 클라우드 에이전트 calls tools to explore your codebase beyond the affected file, generates a fix, validates it (for example, by re-running CodeQL), and iterates until it opens a pull request with the changes. See 코드 검사 경고 해결.
Keep the following in mind:
- Agentic autofix requires Copilot 클라우드 에이전트 and 코파일럿 자동 수정 to be available in the repository. If Copilot 클라우드 에이전트 isn't available, assigning an alert falls back to 코파일럿 자동 수정 instead.
- Each agentic autofix session is billed as a Copilot 클라우드 에이전트 session and consumes AI credits. See GitHub Copilot 클라우드 에이전트 정보.
- Copilot follows any custom instructions configured for the repository or organization when it generates a fix.
- Agentic autofix works on a best-effort basis. Copilot validates fixes by re-running CodeQL using the code-scanning query suite, so it can't confirm that a fix resolves alerts generated by custom queries or the security-extended query suite. Fix quality for alerts from third-party tools is also not guaranteed.
Getting a suggested fix with 코파일럿 자동 수정
코파일럿 자동 수정 generates a single suggested fix for an alert, which you review and apply yourself.
You do not need a subscription to GitHub Copilot to use GitHub Copilot Autofix, and it does not consume AI credits. 코파일럿 자동 수정 is available to all public repositories on GitHub.com, as well as internal or private repositories owned by organizations and enterprises that have a license for GitHub Code Security.
코파일럿 자동 수정 is allowed by default and enabled for every repository that uses CodeQL, regardless of whether it uses default or advanced setup for code scanning. There is no separate step to enable 코파일럿 자동 수정: enabling code scanning with CodeQL is sufficient. See 코드 검사에 대한 기본 설정 구성.
Administrators at the enterprise, organization, and repository levels can choose to disable 코파일럿 자동 수정. If 코파일럿 자동 수정 has been disabled at your level, you can re-enable it by following the same steps used to disable it and selecting the option to allow 코파일럿 자동 수정. To learn how to manage 코파일럿 자동 수정 at each level, see 코드 스캔 보안 경고에 대한 Copilot 자동 수정 비활성화.
