From e08ba426978508faf8c46acc17e95b438a03a59c Mon Sep 17 00:00:00 2001 From: latte Date: Mon, 22 Jun 2026 17:36:01 +0200 Subject: [PATCH 1/3] feat: assign issues to milestones on create/update (#22) Add a `milestone` argument to `create_issue` and `update_issue` accepting either a numeric milestone id or a title (resolved case-insensitively against open and closed milestones, with a clear error for unknown titles). On `update_issue`, `milestone: 0` clears the milestone. A BeforeValidator rejects booleans so they are not silently coerced to an id. Gitea Projects (Kanban boards) were investigated for #22 and are intentionally left unsupported: Gitea 1.26.2 exposes no project endpoints in its REST API. Documented this in api-reference.md and refreshed the (stale) write-mode tool list to cover all 16 write tools.
