What it does

Phaser4 Gamedev is an agent skill from chongdashu/vibejam-starter-pack. Build 2D browser games with Phaser 4: WebGL-first rendering, scenes, filters, lighting, shaders, DynamicTexture and RenderTexture, tilemaps, SpriteGPULayer, TilemapGPULayer, and Phaser 3 to 4 migration work.

Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/migration-hotspots.md`, `references/rendering-and-performance.md` and `references/spritesheets-and-textures.md`).

It sits in Game Development, covering Game development, Sprites and pixel art and 3D graphics and WebGL. The repository describes itself as: Free Vibe Jam starter pack — battle-tested ThreeJS and Phaser agent skills, starter projects, and prompts.

When your agent uses it

  • Tasks that involve Game development
  • Tasks that involve Sprites and pixel art
  • Tasks that involve 3D graphics and WebGL

Example prompts

  • “/phaser4-gamedev”

Workflow steps

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

  1. WebGL-first, not Canvas-first: Phaser 4 is designed around WebGL. Treat Canvas as legacy compatibility, not the default target.
  2. Measure assets before loader config: Sprite and tile bugs often start as incorrect frame metadata, not rendering bugs.
  3. Prefer the simplest rendering path: Use standard game objects until scale or effect requirements justify filters, GPU layers, or shader…
  4. Treat rendering features as architectural choices: Filters, lighting, shaders, and render textures affect coordinate systems, batching…
  5. Migration is selective redesign: Basic scene code may port cleanly, but masks, FX, custom pipelines, shaders, and texture workflows…

What it can do on your machine

Read from SKILL.md and the folder at commit 6793771. 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 (its code samples are typescript).

    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

Phaser4 Gamedev loads about 2.4k tokens when it runs, and up to ~4.7k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 975 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.7k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 975 words (~2,423 tokens).

“Build 2D browser games using Phaser 4's WebGL-first renderer, scene model, and updated rendering APIs.”
