From a50cd989aee06ed0762e26027eadf35933eb52ac Mon Sep 17 00:00:00 2001 From: Julius Marminge Date: Wed, 21 Oct 2026 18:40:54 -0700 Subject: [PATCH 1/7] feat(server): webhook filters fan out over arrays with a [] path wildcard A filter path segment ending in [] resolves to the list of every element's value, so a task can run only when, say, an issue carries a given label: {path: 'body.issue.labels[].name', op: 'equals', value: 'needs more info'}. equals, in and startsWith match when any element does, notEquals only when none equals the value, exists when the list is not empty. Placeholders accept the same syntax and render the list. Before this, filters could only compare scalars and arrays satisfied exists alone, so a GitHub issue_comment hook had to wake the bound thread on every comment in the repository and let the agent discard the rest.
