Overview

RoleSet up and maintain
ScopeTeam of about 10, used on Idle Dungeon Keeper and Idle Airport Manager
Highlights
  • Shared rules, permissions and hooks committed to the repo.
  • Team skills for Figma UI, game data tables, code review and bug fixing.
  • Development process: spec, plan, tests, code, review.
  • SheetGuard API for safe writes to the design Google Sheet.
  • Unity MCP, Figma MCP and GitNexus connected to the agent.

Development process

Every feature goes through these steps. The agent writes the spec, plan and code. A developer makes the decisions shown in orange.

Lessons from Idle Dungeon Keeper

Before starting Idle Airport Manager, the AI setup on Idle Dungeon Keeper was reviewed. Each problem became a rule in the new project.

Two rule files drifting apart→AGENTS.md is the only source; CLAUDE.md imports it
177-line rule file, mostly ignored→Rules ≤ 80 lines, details in Docs/
Plans in 3 folders, no naming→One Docs/plans, dated names, index, archive
Personal, uncommitted permissions→Shared settings.json: allow · ask · deny
Agents re-explored the repo each session→ARCHITECTURE.md + CONVENTIONS.md + review skill
Each developer's agent behaved differently→Team habits moved into a SessionStart hook

Bug fixing and data pipelines

/fix-bugs skill

Takes bugs from GitHub Issues. The agent finds the root cause with GitNexus and suggests fixes, and the developer picks one. Each bug gets its own commit and a Resolved label.

SheetGuard

Google Apps Script API that agents use to write to the design Google Sheet. It can only add tabs, columns and rows. It runs as a dry run by default, locks the sheet while writing and logs every change.
