Can I set permissions for a single job instead of the whole workflow?

Yes, permissions can be defined at the top level for the entire workflow or nested within specific jobs to isolate higher-privilege tasks, such as only allowing a 'release' job to have write access.

Why should I use explicit permissions in GitHub Actions?

Explicit permissions ensure workflows only have the specific access required for their tasks, preventing script injections from pushing malicious code, modifying releases, or creating persistent backdoors.

How do I fix 'Resource not accessible by integration' errors?

This error occurs when the GITHUB_TOKEN lacks a specific permission required for an API call; you can resolve it by adding the necessary scope (e.g., contents: read or pull-requests: write) to the permissions block in your workflow YAML.

What are the default GITHUB_TOKEN permissions?

Default permissions often grant broad read/write access to repository contents, issues, and pull requests, which can create a high attack surface if a workflow or third-party action is compromised.

安全与测试

Implements least-privilege security for GitHub Actions by configuring explicit GITHUB_TOKEN permissions and reducing attack surfaces.

关于

This skill provides specialized guidance for hardening GitHub Actions workflows by moving away from risky default GITHUB_TOKEN settings. It helps developers implement the principle of least privilege by defining explicit permission scopes for repository resources like code, issues, and packages. By using this skill, you can prevent privilege escalation, mitigate the impact of script injection attacks, and ensure your CI/CD pipelines follow industry-standard security patterns for automated authentication.
