--- type: User Story title: "US-006: Announce tree unlocks" description: Celebrate each newly earned species and explain how to control or undo automatic felling. status: backlog --- # US-006: Announce tree unlocks As a **player**, I want visible and actionable feedback when I unlock a species so that I notice the achievement and understand Tree Feller's safety controls. ## Acceptance criteria - [ ] Earning a species unlock displays a configurable on-screen title and subtitle naming the species. - [ ] Earning a species unlock also sends a configurable chat message that explains that sneaking prevents automatic felling and names `/treefeller undo`. - [ ] Title text, subtitle text, fade-in time, display time, fade-out time, and chat text are configurable. - [ ] Messages support the project's chosen Spigot formatting convention and a documented species placeholder. - [ ] The boss bar for the newly unlocked species is removed when its unlock announcement is shown. - [ ] An earned species produces its unlock announcement exactly once unless an administrator later resets that species and the player earns it again. - [ ] An administrative grant clearly informs an online target that access was granted but does not falsely present it as a mined-block achievement. - [ ] Invalid or cancelled breaks never generate an unlock announcement. ## Related - [US-001: Earn tree-type unlocks](us-001-earn-tree-type-unlocks.md) - [US-002: View tree progress](us-002-view-tree-progress.md) - [US-007: Administer Tree Feller](us-007-administer-tree-feller.md) - [US-008: Configure and persist Tree Feller](us-008-configure-and-persist-tree-feller.md)
