Agent Skills

🕹️ Games (game-dev/)

Specialized skills for designing and building 2D games in Go with Ebitengine, chiptune DSP, and procedural generation.

• ebitengineer: Production-grade 2D game architecture, cycle timing, state machines, shaders, and audio sync for Go & Ebitengine (v2).
• game-design: Game concept ideation, interactive /grill-me design interviews, and Game Design Document (GDD.md) generation.
• procedural-art: Pure-code procedural 2D sprites, tilemaps, vector graphics, particle systems, and rasterization algorithms without external assets.
• procedural-composer: Pure-code procedural audio synthesis, sound effects (SFX), and chiptune/FM sound engine architecture.
• sprite-animation: 2D sprite sheets, frame durations, tag loops, and Aseprite (.ase/.aseprite) file validation and slicing.
• vibe-game-developer: Master orchestrator and request router for 2D Go game development, asset pipelines, and WebAssembly deployment.

🎨 GenAI (media/)

Audio and visual generation using Google AI models with ADC authentication.

• lyria: High-fidelity 44.1 kHz stereo music and soundtrack generation from text prompts and images using Google’s Lyria 3 models.
• nano-banana: Conversational image generation and editing using Google’s native Nano Banana models with character consistency support.

💻 Software Engineering (coding/)

Engineering workflow standards, compiler gates, package resolvers, architectural decision records, and language-specific tools.

• adr-template: Guidelines, best practices, and templates for authoring immutable Architecture Decision Records (ADRs).
• engineering-flow: Engineering workflow standards detailing semantic versioning (with 0.x zero-debt rules), broken window hygiene, RFC/ADR planning, and the 7-tier Evidence Hierarchy.
• godoctor: Go developer tooling and static analysis orchestrator with automatic compiler rollback gates, Selene mutation testing, and TestQuery analytics.
• google-oss: Apply and verify Google open-source compliance, Apache-2.0 license headers via addlicense, copyright attributions, and repository disclaimers.
• latest-version: Real-time package registry and Gemini model version resolver (NPM, PyPI, Go proxy, Cargo, RubyGems).

🤖 Agents (agents/)

Frameworks, multi-agent swarm orchestration, and skill authoring tools.

• double-diamond: Two-phase multi-agent orchestration for complex engineering initiatives separating problem space discovery from solution space implementation with human steering gates.
• intercom: Cross-session and cross-project agent communication in Antigravity using the native agentapi CLI and conversation_summaries.db, with automatic session discovery, projectId environment sanitization, and return-address framing.
• parallel: General-purpose task parallelization and agent scaling engine across concurrent subagents.
• show-me-the-money: Mine local conversation history, brain artifacts, and full session transcripts using parallel Flash/Flash-Lite agy CLI workers to recover high-value features lost to conversation drift or abandonment without burning frontier model quota.
• skill-optimizer: Meta-skill for authoring, auditing, and optimizing Agent Skills according to the official specification, trigger evaluation, and MCP setup (https://agentskills.io/mcp).
• swarm-coding: Parallelized multi-agent swarm task decomposition and coordination for complex full-stack features and refactorings.
• uno-reverse: Radical simplification, red-teaming, and Occam’s Razor devil’s advocate for software architecture, PRDs, agent workflows, and technical designs.
