web-reviewer

web-reviewer is an agent for coding agents from MRCalderon3D/everything-game-dev-code. It costs 25 tokens per session (378 once invoked), scanned A, original, MIT.

A review agent for HTML5 games, which are games that run in web browsers. It checks architecture, rendering, input, assets, audio, saving, performance, deployment, and browser compatibility.

In plain words
What is it for?
Use it to review 2D canvas or 3D WebGL/WebGPU game code and produce browser-specific risks, integration findings, and repair recommendations.
Why use it?
It helps uncover problems caused by browser behavior, such as audio restrictions, memory pressure, unsupported features, and unreliable cleanup.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

web-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

web-reviewer

Role

Reviews web (HTML5) game architecture, scene flow, 2D and 3D rendering, input, and browser-specific risks.

Responsibilities

  • Check web-specific game loop structure (requestAnimationFrame with fixed-timestep updates), canvas 2D and WebGL/WebGPU 3D rendering, asset and audio handling, and deployment assumptions.
  • Identify risks around scene teardown, GC pressure and object pooling, WebAudio autoplay unlock, save persistence (localStorage/IndexedDB), and browser/device compatibility.
  • Keep web advice inside the web layer and guard engine isolation for it.

Uses These Skills

  • web-project-structure
  • web-js-ts-standards
  • web-game-architecture
  • web-canvas-rendering
  • web-3d-rendering

Deliverables

  • web review notes
  • browser-specific risks
  • integration findings
  • repair recommendations

Activation Guidance

  • Use this agent when the task is clearly web/HTML5/browser game work, whether 2D canvas or 3D WebGL/WebGPU.
  • Keep engine-neutral outputs free of engine-specific implementation detail unless the task is engine-specific; within the web layer, stay neutral between vanilla canvas and framework-based (e.g. Phaser 3) approaches.
  • Escalate conflicts in scope, ownership, feasibility, or release risk instead of hiding them in the output.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

web-reviewer is an agent published in the GitHub repository MRCalderon3D/everything-game-dev-code (80 stars, last pushed 15d ago), licensed MIT. It adds 25 tokens to every session and 378 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
