What github_trigger_workflow does on Github

AI agents invoke github_trigger_workflow to trigger actions in Github. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

Why github_trigger_workflow is rated High

Triggering a GitHub Actions workflow executes code in a CI/CD context whose effects depend on the workflow's implementation and arguments. This can modify repositories, deploy applications, run scripts, or interact with external systems. While not inherently destructive or financial, the blast radius is high if a workflow performs sensitive operations (deployments, credential rotation, data processing).

From the tool's definition Tool name 'github_trigger_workflow' combined with server's stated capability to manage 'GitHub Actions' indicates execution of automated workflows. The 'trigger' verb and GitHub Actions context establish this as an action that runs external operations.
