Mention in PR¶

AI assistant for PRs — review, fix code, and push changes on demand.

How it works¶

Activated by a comment on a pull request or inline review thread (the example trigger uses /ai, but the prefix is configurable). Reads the PR diff and codebase, then reviews code, answers questions, pushes fixes to the PR branch, or resolves review threads.

Quick Install¶

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

Trigger¶

Event	Types	Condition
`issue_comment`	`created`	Comment on a PR; the example trigger filters on `/ai` prefix
`pull_request_review_comment`	`created`	Inline review comment; the example trigger filters on `/ai` prefix

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¶

add-comment — reply to the PR conversation
create-pull-request-review-comment — inline review comments
submit-pull-request-review — submit a review
push-to-pull-request-branch — push code changes to the PR branch
resolve-pull-request-review-thread — resolve review threads
