Using GodotPrompter

Related skills: godot-project-setup for scaffolding a new project, godot-grill for settling open design decisions first, godot-brainstorming for design exploration, godot-code-review for reviewing finished code, godot-debugging for diagnosing runtime issues.

GodotPrompter provides Godot 4.x domain-specific skills for AI coding agents. Skills cover project setup, architecture patterns, gameplay systems, UI, multiplayer, testing, and deployment — for both GDScript and C#.

How to Access Skills

In Claude Code: Use the Skill tool with the skill name (e.g., Skill: "godot-prompter:state-machine").

In Copilot CLI: Use the skill tool. Skills are auto-discovered from installed plugins.

In Gemini CLI: Deprecated (succeeded by Antigravity CLI).

In Cursor: Skills are loaded via custom instructions / rules system.

In Codex: Skills load natively via the AGENTS.md re-export. Follow skill instructions directly; see references/codex-tools.md for tool mapping.

In OpenCode: Skills are discovered from the installed plugin. Use the /skills command to browse or invoke skills directly. See .opencode/INSTALL.md for setup.

In Antigravity (2.0, IDE, CLI): Skills activate automatically when your prompt matches a skill's description frontmatter — no tool call needed. Install the plugin using:

agy plugin install https://github.com/jame581/GodotPrompter

For manual, workspace, or cross-project installations:

Installing GodotPrompter for Antigravity

Workspace (project-scoped) — recommended for active development:

# Linux / macOS — from your Godot project root:
mkdir -p .agents
ln -s /path/to/GodotPrompter/skills .agents/skills

# Windows (PowerShell, Developer Mode or run as admin):
New-Item -ItemType Directory -Force .agents | Out-Null   # junction won't create the parent
New-Item -ItemType Junction -Path .agents\skills -Target D:\Godot\GodotPrompter\skills

Legacy path note: .agent/skills/ (singular) was the early CLI convention; .agents/skills/ (plural) is the current standard for all Antigravity products.

Global (cross-project):

# Official path (Google Codelabs): ~/.gemini/config/skills/
# Symlink individual skill folders so each is a direct child (recommended):
mkdir -p ~/.gemini/config/skills/
ln -s /path/to/GodotPrompter/skills/* ~/.gemini/config/skills/

~/.gemini/skills/ is a community-verified alias but not the path the official Codelabs docs name. Prefer ~/.gemini/config/skills/ for new installs.

Nesting caveat: Prefer ln -s skills/* over cloning the repo directly into the skills dir, so each skill is an immediate child (<skills-dir>/<skill-name>/SKILL.md). Confirm nested discovery works before relying on the clone approach.

See references/antigravity-tools.md for the full tool mapping and SKILL.md frontmatter details.

Coexistence with Other Plugins (e.g., Superpowers)

<!-- SESSION-CARD-START -->

GodotPrompter is active in this Godot project.

Workflow plugins decide how you work; GodotPrompter decides what you build. Both apply.

RULE: before implementing any Godot system, invoke the matching godot-prompter:* skill. Applies to subagents writing Godot code too.

Situation	Start with
New system, or the requirements are unclear	godot-grill — settle decisions, then design and build
Known change, explicit ask, bug fix	the domain skill below — build

Then report before you build: name the pattern you picked, the alternative you rejected, and why. Skills carry trade-offs — surface them. The choice is the developer's.

Building…	Start with
Movement, input, cameras	player-controller, input-handling, camera-system
Architecture	state-machine, event-bus, scene-organization, component-system, resource-pattern, dependency-injection
Gameplay systems	inventory-system, dialogue-system, ability-system, save-load
Enemy AI	ai-navigation
UI, HUD, i18n	godot-ui, hud-system, responsive-ui, localization
Animation, tweens, audio	animation-system, tween-animation, audio-system
Physics, 2D, 3D	physics-system, 2d-essentials, 3d-essentials
Shaders, VFX, procgen, math	shader-basics, particles-vfx, procedural-generation, math-essentials
Multiplayer	multiplayer-basics, multiplayer-sync, dedicated-server
Mobile, XR, native, threads	mobile-development, xr-development, gdextension, multithreading
Editor tools, assets	addon-development, assets-pipeline
GDScript / C# idioms	gdscript-patterns, gdscript-advanced, csharp-godot, csharp-signals
Test, debug, profile, review	godot-testing, godot-debugging, godot-optimization, godot-code-review
Setup, design, export	godot-project-setup, godot-grill, godot-brainstorming, export-pipeline
Teaching while building	godot-mentor
Addons (if installed)	limboai, beehave, popochiu, dialogue-manager, phantom-camera

Full index: invoke godot-prompter:using-godot-prompter.

Red flags — you are rationalizing:

Thought	Reality
"I know how CharacterBody2D works"	Knowing the class ≠ knowing the pattern. Invoke.
"It's a two-line script"	Two-line scripts still pick node types. Invoke.
"The plan says what to build"	The plan says what. The skill says how. Invoke.
"I loaded a Godot skill already"	Different system, different skill.
"The user wants a quick fix"	Quick fixes set architecture. Invoke — then say what you picked.
"The skill shows one pattern, so it's settled"	Skills carry trade-offs. Surface them; don't decide alone.
"I'll explain it once it works"	A choice reported after the code is a fait accompli, not a choice.

Workflow: From Idea to Working Game

GodotPrompter handles the full development workflow. No other plugins required.

1. Design Phase

Load godot-prompter:godot-grill first when design decisions are open — it settles them in rounds and records them. Then godot-prompter:godot-brainstorming guides you through:

• Proposing architectural approaches with trade-offs
• Designing scene trees, signal maps, and data flow
• Creating an implementation plan with ordered tasks

2. Implementation Phase

For each task in the plan, load the relevant domain skill:

• Building a player? Load godot-prompter:player-controller and godot-prompter:state-machine
• Adding inventory? Load godot-prompter:inventory-system
• Need save/load? Load godot-prompter:save-load

Each skill provides complete code examples, Godot best practices, and a checklist.

3. Review Phase

Load godot-prompter:godot-code-review to review the code against Godot-specific checklists.

Agents

• godot-game-architect — Designs systems, plans scene trees, chooses patterns
• godot-game-dev — Implements features guided by skills
• godot-code-reviewer — Reviews code against Godot best practices
• godot-shader-author — Authors custom shaders, post-processing, Compositor effects
• godot-performance-profiler — Diagnoses performance issues from profiler data
• godot-animator — Designs animation graphs, blend trees, IKModifier3D, BoneConstraint3D, retargeting
• godot-csharp-engineer — C#-first development; parity mode for closing this repo's C# debt
• godot-ui-designer — Builds Control-tree UI — themes, responsive layouts, localization-aware
• godot-tools-engineer — Editor plugins, custom inspectors, gizmos, @tool scripts, plugin distribution

Plan Storage

GodotPrompter has no plans folder of its own. Save implementation plans where this project keeps them, checking in order: the user's instructions or the project's agent instructions file (CLAUDE.md, AGENTS.md, …); then the planning skill's convention; then an existing plans directory. If none applies, ask the user, suggesting docs/plans/, or use docs/plans/ when you cannot ask (a subagent or non-interactive run). Per-scene designs from godot-brainstorming stay next to the scene, in the root script's comment block or a DESIGN.md.

Implementation Checklist

• Identified the matching domain skill via the table above before writing any system code
• Invoked the identified skill with the Skill tool (or platform equivalent) before implementation
• When a workflow plugin is also active (Superpowers, etc.), still invoked the relevant godot-prompter domain skill during implementation — they are complementary, not exclusive
• After implementation, ran godot-prompter:godot-code-review to validate against Godot best practices
• Logged any newly-discovered domain gap that no current skill covers, so it can become a future skill
