GitHub Bot

The Mastra GitHub bot receives GitHub webhook events and routes them through Code Assist workflows.

Supported Event Inputs

The dispatcher handles:

• issue_opened
• issue_labeled
• issue_comment_created
• pr_comment_created
• pr_review_comment_created
• pr_review_submitted
• pr_checks_completed
• pull_request_closed
• promotion_workflow_completed

Labels

The bot manages these labels:

Label	Meaning
planning	Code Assist is preparing a plan.
needs-answer	The planner needs clarification.
plan-ready	The final implementation plan is posted.
plan-error	Planning failed.
implementation-ready	Trusted actor approved implementation.
auto-merge-when-green	Bot may auto-merge after checks pass.
implementing	Implementation is active.
implementation-blocked	Bot stopped for human review.
pr-open	Draft PR is open.

Trust Model

Implementation starts only from trusted actors or approved autonomy policy. The service checks collaborator permission and ignores generated bot comments to avoid self-trigger loops.

PR Follow-Up Sources

The PR follow-up workflow can be triggered by:

• trusted PR comments;
• review comments;
• submitted reviews;
• failed check events;
• successful checks that may enable merge;
• PR close events;
• promotion workflow completion events.
