Implement game mechanic functions via worker dispatch. Covers risk-first then main implementation. Dispatches workers until PLAN is clean, then runs one verify+review pass; loops until convergence. Explicit invocation only — use /gm-build.
Skill Claude CodeCodex
Evaluate the current tag's quality: enforce the playable-closed-loop gate, maintain a single cross-tag e2e/ suite that always reflects the current game (add tests for new mechanics, prune tests for mechanics this tag deliberately removed), and reason about gameplay quality. Independent from the build process — fresh…
Skill Claude CodeCodex
Seal the current tag: snapshot the per-tag working docs into docs/tags/ /, write a CHANGELOG entry, run git tag, and reset per-tag runtime state for the next /gm-gdd round. Does NOT package a release — that lives in a separate skill. Explicit invocation only — use /gm-finalize.
Skill Claude CodeCodex
Fix gaps identified by the Evaluator. Generates GAP.md from evaluation.json, dispatches workers to address critical/major issues, then runs one final verify+review pass. Unlike gm-build (PLAN.md-driven), gm-fixgap is GAP.md-driven. Explicit invocation only — use /gm-fixgap.
Skill Claude CodeCodex
Game Design Document phase for one tag. On the first ever run, runs the full Socratic interview, produces GDD.md, and derives ROADMAP.md (split into SemVer-tagged release tags). On every subsequent run, focuses the conversation on the current tag (the earliest entry in ROADMAP.md without a git tag), optionally updates…

Self-diagnostic skill for godotmaker itself. Invoked when the main pipeline can't make progress (e.g. several fixgap rounds in a row failed to converge). NOT a "smarter fixgap" — does not modify game code, does not write files, only reports diagnosis to chat. If a godotmaker-side defect is the root cause, drafts an…
Skill Claude CodeCodex
Scaffold a new Godot project: project.godot + addons + base directories + e2e/conftest.py + initial git commit. Lifetime-once role — runs only on fresh projects. Explicit invocation only — use /gm-scaffold.
Skill Claude CodeCodex
Mechanical verification of the built game: headless build, unit tests, lint, static checks. Explicit invocation only — use /gm-verify.
Skill Claude CodeCodex
Look up Godot engine class APIs — methods, properties, signals, enums. Use when you need to find which class to use or look up specific API details. Supports version-specific docs — reads the correct API for the project's Godot version.
Skill Claude CodeCodex
Write and run E2E (end-to-end) game tests using the godot-e2e framework. Python controls a live Godot game over TCP — Locator-based semantic queries, expect() auto-retry assertions, and engine log capture make failures self-diagnosing. Use this skill whenever you need to: Test actual gameplay: player movement…
Skill Claude CodeCodex
Compile-check a Godot project using headless mode. Use after writing or modifying any GDScript or C# code to verify it compiles. Triggers: after code changes, before running tests, when build errors need diagnosis. Also use this when the user says "check if it compiles", "build check", "does this parse", or after any…
Skill Claude CodeCodex
Manage Godot input action mappings in project.godot. Use when adding input actions, changing key bindings, setting up controls for a new genre, or validating that all referenced actions exist. Called by project-scaffold (initial setup), workers (new mechanics), and the dispatching role (GDD changes requiring new…
Skill Claude CodeCodex
Runtime debugging and live project inspection via godot-mcp. Use when headless tools cannot diagnose the problem: code compiles but runtime behavior is wrong, tests pass but the game does not work as expected, or you need to inspect live state (node tree, console output, rendering). Escalation trigger: a task has…
Skill Claude CodeCodex
Guidance for using the optional Phantom Camera Godot addon in generated projects. Use when a Godot 4 game explicitly opts into Phantom Camera, already has the addon installed, or needs camera behavior that is cleaner with multiple virtual cameras than with a hand-written Camera2D script. Do not require this addon for…
Skill Claude CodeCodex
Generate a new Godot game project with standardized ECS structure and tooling. Use when starting a new game: "create a project", "set up a new game", "scaffold", "initialize", "new project", "start building", "let's make it". Triggers after game-planner produces a confirmed plan, or when the user provides a game name…
Skill Claude CodeCodex
Capture gameplay screenshots using godot-e2e for visual verification. Use when you need to: take a screenshot of the running game, capture multiple screenshots during an E2E scenario, generate reference.png, visually verify game state, or provide screenshots for VQA analysis. Triggers: "screenshot", "capture…
Skill Claude CodeCodex
Visual quality assurance: analyze game screenshots for defects, compare against reference, check motion in frame sequences. Supports runtime-native inspection plus Gemini or OpenAI API-backed VQA.
