 ### Limitations in Copilot's compatibility with other features
 
 * **{% data variables.product.prodname_copilot_short %} does not sign its commits**. If you have the "Require signed commits" rule or branch protection enabled, you must rewrite the commit history in order to merge {% data variables.product.prodname_copilot_short %}'s pull requests. See [AUTOTITLE](/repositories/configuring-branches-and-merges-in-your-repository/managing-rulesets/available-rules-for-rulesets#require-signed-commits).
-* **{% data variables.product.prodname_copilot_short %} does not work with self-hosted {% data variables.product.prodname_actions %} runners**. {% data variables.product.prodname_copilot_short %} has access to its own development environment, running in {% data variables.product.prodname_actions %}, and must use {% data variables.product.prodname_dotcom %}-hosted runners. See [AUTOTITLE](/copilot/customizing-copilot/customizing-the-development-environment-for-copilot-coding-agent#upgrading-to-larger-github-hosted-github-actions-runners).
 * **{% data variables.copilot.copilot_coding_agent %} does not work in personal repositories owned by {% data variables.enterprise.prodname_managed_users %}**. This is because {% data variables.copilot.copilot_coding_agent %} requires {% data variables.product.company_short %}-hosted runners, which are not available to repositories owned by {% data variables.enterprise.prodname_managed_users %}. See [AUTOTITLE](/actions/using-github-hosted-runners/using-github-hosted-runners/about-github-hosted-runners).
 * **{% data variables.copilot.copilot_coding_agent %} doesn't account for content exclusions**. Content exclusions allow administrators to configure {% data variables.product.prodname_copilot_short %} to ignore certain files. When using {% data variables.copilot.copilot_coding_agent %}, {% data variables.product.prodname_copilot_short %} will not ignore these files, and will be able to see and update them. See [AUTOTITLE](/copilot/managing-copilot/configuring-and-auditing-content-exclusion/excluding-content-from-github-copilot).
 * **{% data variables.copilot.copilot_coding_agent %} only works with repositories hosted on {% data variables.product.github %}**. If your repository is stored using a different code hosting platform, {% data variables.product.prodname_copilot_short %} won't be able to work on it.
