What it does

Threejs QA Release is an agent skill from mintdotgg/mint-threejs-skills. Verify and release Three.js apps and games through primary-journey QA, desktop/mobile visual checks, canvas metrics, visual regression, optional game bot playtests, production previews, and release-risk reporting.

Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `references/game-playtest-bot.md`, `references/qa-release-checklists.md` and `references/visual-test-harness.md`).

It sits in Game Development, covering 3D graphics and WebGL and Visual regression testing. 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
  • Tasks that involve Visual regression testing

Example prompts

  • “/threejs-qa-release”

Requirements

  • Node.js

Workflow steps

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

  1. Confirm the approved scope, then start the intended dev or production
  2. Capture console, page, and relevant network errors.
  3. Verify nonblank canvas pixels and the approved active desktop view.
  4. Exercise the primary user journey and changed risky paths.
  5. Test loading, empty, unsupported, and error states when applicable.
  6. Check desktop UI fit, input cancellation, and resize.
  7. If audio changed, verify gesture unlock, decode/load, triggers, loops,
  8. Add deterministic screenshot baselines only when separately approved;
  9. Run canvas diagnostics, profiling, production-preview checks, or game bot
  10. Record commands, artifacts, issues, and remaining risks.

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

    Ships 1 file in scripts/ (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node

    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 QA Release loads about 856 tokens when it runs, and up to ~4.4k if it reads all its reference files. Until then it costs about 58 tokens; SKILL.md has 404 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~856
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.4k

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); the scripts in this folder are not scanned.

description
Verify and release Three.js apps and games through primary-journey QA, desktop/mobile visual checks, canvas metrics, visual regression, optional game bot playtests, production previews, and release-risk reporting.

Three.js QA Release

Prove the app or game works as its user encounters it and that the production build is shippable.

Read ../../references/verification-policy.md first. Do not start browser, Playwright, canvas, screenshot, diagnostics, release-preview, or mobile work without approval for that scope.

Read By Need

  • Core QA, responsive behavior, performance, evidence, and release: references/qa-release-checklists.md.
  • Screenshot baselines or visual regression: references/visual-test-harness.md.
  • Game-only scripted play, difficulty, fairness, or softlocks: references/game-playtest-bot.md.

Default Minimum

Without additional approval, run only the policy's automatic minimum: the smallest build/typecheck gate, focused existing non-browser tests, and local asset/import-path checks. Fix owned failures, then state that extended browser QA was not run and offer a concrete desktop QA pass.

Approved Desktop QA Workflow

  1. Confirm the approved scope, then start the intended dev or production preview.
  2. Capture console, page, and relevant network errors.
  3. Verify nonblank canvas pixels and the approved active desktop view.
  4. Exercise the primary user journey and changed risky paths.
  5. Test loading, empty, unsupported, and error states when applicable.
  6. Check desktop UI fit, input cancellation, and resize.
  7. If audio changed, verify gesture unlock, decode/load, triggers, loops, cleanup, mute, and volume.
  8. Add deterministic screenshot baselines only when separately approved; otherwise record that they were not run.
  9. Run canvas diagnostics, profiling, production-preview checks, or game bot playtests only when the user approved those checks.
  10. Record commands, artifacts, issues, and remaining risks.

After desktop QA, offer mobile as a separate second step. Do not infer mobile approval from desktop approval.

Canvas Inspector

After canvas-inspector approval, run from the target project so its @playwright/test and pngjs dependencies are used:

bash
node <this-skill-dir>/scripts/inspect-threejs-canvas.mjs --url http://127.0.0.1:5188

Add --mobile, --state <name>, and --seed <n> as needed. The JSON contains canvas metrics and renderer-budget comparisons. Blank/error conditions exit nonzero.

The game scaffold creator copies this canonical inspector into generated games, so they remain self-contained without duplicated source.

Approved Release Workflow

  1. Inspect scripts, Vite base, public assets, and deployment assumptions.
  2. Gate debug UI, verbose logging, and test helpers.
  3. Run production build and preview.
  4. Recheck desktop/mobile interaction and asset paths in built output.
  5. Review bundle size, large assets, and third-party asset notices.
  6. Report deployment commands and residual risks.

Final Response

Lead with pass/fail. Include commands, URL, primary journey or game loop, controls, screenshots/artifacts, issues, canvas/performance evidence, visual harness and game-bot decisions when relevant, deployment notes, and risks. Always disclose extended browser QA that was not run and whether mobile still requires approval.
