Persistent memory, BM25 code search, MCP tools, and hook guardrails for AI coding agents — Claude Code, Codex CLI & Antigravity. One local-first .ai/ layer per repo. No SaaS, no network on hot paths.
This repository also configures its own agents. See what code-brain tells them →
Skill Claude Code
Build, install, run, and verify a reusable image-to-game-ready-3D pipeline for Unity with controlled ImageGen references, approved AI mesh providers, Blender MCP/CLI, modular era catalogs, Blender retopology/LOD/pivot processing, and Unity import/render proof. Use for 2D-to-3D assets, vehicles, aircraft, ships…
Skill Claude Code
A checklist and audit guide for in-app purchases, subscriptions, and quota billing. It covers store verification, user entitlements, webhooks, reconciliation, and an append-only ledger, which is a record where entries are added rather than rewritten.
Skill Claude Code
A checklist for reviewing code changes before they are merged into a shared codebase. It checks whether the changes match the request and follow project rules.
Skill Claude Code
A bug-diagnosis workflow that uses records of earlier failures, decisions, and lessons. It checks whether past findings still apply to the current version and environment before investigating the code.
Skill Claude Code
A workflow for reproducing a software bug, identifying its cause, and applying the smallest fix. It includes focused verification and optional failure-first tests.
Skill Claude Code
A process for implementing a requested software feature with the smallest necessary change.
Skill Claude Code
A read-only scanner for intentional simplification markers in a code repository. These markers record code that has a known limit and should be revisited when a stated condition occurs.
Skill Claude Code
A review focused only on code that may be more complicated than needed. It identifies candidates for deletion, standard-library or built-in replacements, and shorter equivalent code.
Skill Claude Code
A small-step refactoring workflow that keeps existing behavior unchanged. Refactoring means improving code structure without intentionally changing what the software does.
Skill Claude Code
A test-first implementation workflow that recalls past decisions, conventions, and lessons before coding. TDD, or test-driven development, means writing a failing test first, then implementing the code and finally cleaning it up.
