Breaking Change Detect¶

Detect undocumented breaking changes in public interfaces.

How it works¶

Scans recent commits (1-day lookback, 3-day on Mondays) for public interface or behavioral changes. Cross-references each commit against its PR description, changelog, and documentation before concluding a change is undocumented.

Quick Install¶

mkdir -p .github/workflows && curl -sL \
  https://raw.githubusercontent.com/elastic/ai-github-actions/v0/gh-agent-workflows/breaking-change-detect/example.yml \
  -o .github/workflows/breaking-change-detect.yml

Trigger¶

Event	Schedule
`schedule`	Weekdays
`workflow_dispatch`	Manual

Inputs¶

Input	Description	Required	Default
`additional-instructions`	Repo-specific instructions appended to the agent prompt	No	`""`
`setup-commands`	Shell commands run before the agent starts	No	`""`
`allowed-bot-users`	Allowlisted bot actor usernames (comma-separated)	No	`github-actions[bot]`

Safe Outputs¶

create-issue — file a breaking change report (max 1, auto-closes older reports)
