+### Task 138 — Discord Rules Mod (CurseForge Release)
+**Goal:** Fork the Firefrost-specific rules mod into a generic version and publish on CurseForge.
+
+**What to do:**
+- Create `services/rules-mod/discord-rules/` directory (fork from 1.21.1 code)
+- Mod name: "Discord Rules" (not "Firefrost Rules")
+- Remove Fire/Frost/Arcane color detection — replace with configurable header_color and body_color in TOML config
+- Remove emoji-to-bracket conversion (or make it a config toggle)
+- Generic branding in mods.toml, MIT license
+- Compile all 3 versions (1.21.1, 1.20.1, 1.16.5)
+- Draft CurseForge project page description and changelog
+
+**Source code:** `services/rules-mod/1.21.1/`, `1.20.1/`, `1.16.5/`
