Potential fix for code scanning alert no. 3: Workflow does not contain permissions

[ajm19826]

Potential fix for https://github.com/houselearning/Clean/security/code-scanning/3

In general, the fix is to explicitly add a permissions: block to the workflow or job so that the GITHUB_TOKEN granted to this workflow is limited to the minimal scopes required. For this particular workflow, it only needs to read repository contents to check out code and run a script, so contents: read at the workflow or job level is sufficient.

The best fix without changing existing functionality is to add a permissions: block near the top of the file so it applies to all jobs. Insert it after the on: trigger block and before jobs:. This will ensure that the typo-check job runs with a token that has read-only access to repository contents, avoiding unnecessary write permissions. No imports, methods, or other definitions are required; this is purely a YAML configuration change within .github/workflows/pr-typo-fixes.yml.

Concretely:

• Edit .github/workflows/pr-typo-fixes.yml.
• After line 5 (the last line of the on: block), add:

  permissions:
    contents: read

This documents and enforces the intended minimal permissions for the workflow.
