Build Reusable 3D Maps with Three Scope Map

Where this fits

A developer needs a 3D globe that zooms into a province-level China map, with drilldown to cities and districts, all using the same visual theme. They are using Codex to generate the code, but the output often needs manual fixes for scope switching and color consistency. This skill packages a validated template that eliminates those repetitive adjustments.

Why agents benefit

• Codex can reliably copy and adapt a pre-validated map template instead of inventing a new renderer each time, reducing runtime errors.
• The skill enforces a scope-first workflow: it determines world, country, China, province, city, or district boundaries before generating any geometry, so the agent never mixes up coordinate systems.
• It includes a single-theme color derivation method: from one brand color, the agent can generate the full palette for map faces, borders, labels, and effects, preserving a dark HUD look.
• Drilldown transitions (world → country → province → city → district) are handled as built-in behaviors, so the agent can implement zoom-in/out without custom animation code.
• The skill validates the generated map against a known good style, catching issues like misaligned labels or broken fly lines before the agent presents the code.

Practical scenarios

From Earth View to a China Province Map

The agent starts with a rotating globe and, on user interaction, transitions to a flattened China map with province boundaries, using a smooth morph. The skill's template includes the exact interpolation and camera positions, so the agent just sets the starting and ending scopes.

Theming a Dark HUD Dashboard

A user asks for a map that matches their existing dark dashboard with neon cyan highlights. The agent feeds the theme color "cyan" into the skill's color derivation function. It outputs a cohesive set of materials, glow effects, and label colors that blend with the existing UI.

Swapping GeoJSON for a City Drilldown

The user wants to replace default province boundaries with a custom GeoJSON for a specific city, then add district-level drilldown. The skill's validation step ensures the new data conforms to the expected structure, and the agent can reuse the same label and scatter-point logic across the new scope.

Add it to your agent workflow

Install the skill via the CLI, then tell Codex to use it in your prompt.

npx skills add songsummer920-dazzle/three-scope-map-skill --skill three-scope-map

In your agent prompt, say: "Build a Three.js globe that drills down to a province map of China using the three-scope-map skill. Theme it with a single dark-blue color."

Compare before adopting

Look at how often the skill’s template is updated (maintenance freshness) and whether the bundled GeoJSON covers the scopes you need. Compare its validation approach with other map generation skills that might rely on ad-hoc code. Check if the skill works with your target framework (Vue, React, plain web) and how portable the generated code is.

Why it is worth tracking

The skill has 472 stars and an active maintainer, indicating community trust. The specific combination of scope switching, drilldown, and theme derivation is rare in agent skills, and the validation step adds a quality gate that many similar tools lack. Evaluate it when you need consistent, reusable 3D geographic visuals across multiple projects.
