You can now read the parent issue or pull request when your bot is mentioned in a Linear or GitHub comment. message.subject resolves to that parent with title, status, URL, and the full typed payload.
bot.onNewMention(async (thread, message) => {
const subject = await message.subject;
if (subject) {
await thread.post(
`This is about: ${subject.title} (${subject.status})\n${subject.url}`
);
}
});
Reply to a mention with the parent issue's title, status, and URL
message.subject is cached per message, so repeated access only hits the API once. It resolves to null on Slack and other chat platforms, where there's no parent resource.

The GitHub, Linear, and Slack adapters now expose their underlying platform SDKs. Use them to extend your bot by calling provider APIs directly.
// Add a "triaged" label to issue #42
const { octokit } = bot.getAdapter("github");
await octokit.rest.issues.addLabels({ owner: "vercel", repo: "chat", issue_number: 42, labels: ["triaged"] });
// Create a new issue in a team
const { linearClient } = bot.getAdapter("linear");
await linearClient.createIssue({ teamId: "TEAM_ID", title: "Investigate flaky test" });
// Pin a message in a channel
const { webClient } = bot.getAdapter("slack");
await webClient.pins.add({ channel: "C123ABC", timestamp: "1234567890.123456" });
Add a GitHub label, create a Linear issue, or pin a Slack message
The previous .client getter remains as a @deprecated alias on the adapters.
