What it does

Threejs Interaction Systems is an agent skill from mintdotgg/mint-threejs-skills. Build Three.js app interaction systems including cameras, controls, picking, selection, manipulation, annotations, configuration UI, loading states, responsive input, and accessibility.

Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/interaction-patterns.md`).

It sits in Game Development, covering 3D graphics and WebGL. It works with Three.js. The repository describes itself as: Agent guidance for building polished Three.js apps and games with Mint MCP. The licence is MIT.

When your agent uses it

  • Tasks that involve 3D graphics and WebGL

Example prompts

  • “/threejs-interaction-systems”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Define the primary user task and supported input methods.
  2. Choose one camera/control owner and explicit transition rules.
  3. Keep application state outside transient Three.js object state.
  4. Implement raycast or GPU picking only at interaction boundaries, with clear
  5. Add manipulation, configuration, annotations, playback, or navigation as
  6. Keep semantic HTML controls available for important actions and status.
  7. Verify pointer, keyboard, touch, resize, cancellation, and loading/error

What it can do on your machine

Read from SKILL.md and the folder at commit de7af44. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Threejs Interaction Systems loads about 403 tokens when it runs, and up to ~989 if it reads all its reference files. Until then it costs about 53 tokens; SKILL.md has 158 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~403
With references · SKILL.md plus every file in references/, read only if the agent opens them
~989

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Build Three.js app interaction systems including cameras, controls, picking, selection, manipulation, annotations, configuration UI, loading states, responsive input, and accessibility.

Three.js Interaction Systems

Make 3D interaction predictable, state-driven, responsive, and accessible.

Read references/interaction-patterns.md before changing camera controls, selection, manipulation, configuration, annotations, or general app UI. For model axes, authoritative transforms, constrained manipulation, or surface queries, also read ../../references/spatial-contracts.md.

Workflow

  1. Define the primary user task and supported input methods.
  2. Choose one camera/control owner and explicit transition rules.
  3. Keep application state outside transient Three.js object state.
  4. Implement raycast or GPU picking only at interaction boundaries, with clear hover, focus, selected, disabled, and error feedback.
  5. Add manipulation, configuration, annotations, playback, or navigation as task-specific modules.
  6. Keep semantic HTML controls available for important actions and status.
  7. Verify pointer, keyboard, touch, resize, cancellation, and loading/error paths on relevant viewports.

Use ../../references/mint-mcp-assets.md for generated production assets. Ordinary interface chrome should remain HTML/CSS/SVG/Canvas unless a true 3D surface is required.

Final Response

Report the interaction model, controls, state ownership, supported input paths, responsive/accessibility evidence, screenshots, and remaining risks.
