What problem does it solve? Contributors to the kami-kakushi incremental RPG codebase need to know exactly which files to touch, in what order, and which gates to run when adding new game content, and this Skill provides that cookbook so changes land without breaking generated artifacts, golden pins, or verification gates. ## Core Features & Use Cases - Ten numbered recipes: Covers adding player actions/intents, quests, map zones, narrative beats, balance constants, UI surfaces, fixture scenarios, DEV panel tabs, config flags, and tests, each listing files in order, known traps, routing, and verification steps. - Change-control routing: Each recipe names the mandatory companion skill or gate (tdd, narrative-diverge, map-sheets, diverge, review-link) so work follows the project's ADR-driven process. - Use Case: When asked to add a new quest, the Skill directs you to append a QuestDef in src/core/content/quests.ts, author prose in flavor.md, confirm event tokens are emitted, run narrative-diverge for fiction text, and verify via vitest plus a live fixture load. ## Quick Start Ask the assistant to add a new player action to the kami-kakushi game and follow the recipe's ordered file list, trap warnings, and verification commands.
