What it does

Test Playable Web Games is an agent skill from nirholas/three.ws. Test a playable browser game end to end with deterministic fixtures and real browser evidence. Use for gameplay QA, regression testing, controls, accessibility, responsive/mobile testing, save flows, console checks, performance smoke tests, and release verification.

Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Testing & QA, covering QA and bug reports, Mobile testing and debugging and Game development. The repository describes itself as: Open-source platform for 3D AI agents. Turn text or a photo into a rigged, animated GLB avatar, give it an LLM brain, memory and a wallet, and embed it anywhere with one web… The licence is Apache-2.0.

When your agent uses it

  • Regression testing
  • Responsive/mobile testing
  • Performance smoke tests
  • Release verification

Example prompts

  • “/test-playable-web-games”

What it can do on your machine

Read from SKILL.md and the folder at commit ec8d1d2. 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

Test Playable Web Games loads about 429 tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 179 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~73
When it runs · the whole SKILL.md, loaded when a task matches
~429

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.

Test a playable browser game end to end with deterministic fixtures and real browser evidence. Use for gameplay QA, regression testing, controls, accessibility, responsive/mobile testing, save flows, console checks, performance smoke tests, and release verification.

Test Playable Web Games

Combine deterministic tests with short real playthroughs. Do not treat a green build as gameplay proof.

Start with a test matrix

Map the player journey: launch, new game, controls, core action, enemy encounter, reward, inventory/progression, save/continue, loss/retry, pause, settings, and completion. Add device variants for desktop keyboard/mouse, touch portrait, touch landscape, and reduced motion.

Prefer deterministic review states

Create seedable fixtures, debug routes, or query parameters for combat phase, inventory loadout, boss phase, tutorial step, save migration, low health, and error states. Test important transitions directly rather than grinding through the campaign.

Verify the player experience

Use the repository-approved browser surface and honor local browser restrictions. Confirm screen-visible feedback after each meaningful action: control response, target state, damage/resource state, UI update, and navigation. Inspect console warnings/errors and sample performance only on a representative live scene.

Report actionable evidence

Record reproduction steps, expected versus actual result, severity, device/viewport, and the shortest useful proof. Separate new regressions from pre-existing baseline issues. After testing, close idle browser pages, dev servers, and benchmarks while leaving active task resources alone.
