gsp-polished-prototype

gsp-polished-prototype is a skill for Claude Code, Codex from mike007jd/game-superpowers. It costs 25 tokens per session (287 once invoked), scanned A, original, MIT.

A game-development checklist and workflow for building a coherent, demo-ready prototype rather than a barely playable test version.

In plain words
What is it for?
Use it to build the core game loop, menus, HUD, feedback, visual direction, fail-and-retry flow, and production-ready code structure, then verify the result.
Why use it?
It prevents important requested features and finishing details from being cut just to get something playable. It also checks that the game is readable, complete enough to try, and structured for continued development.

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

gsp-polished-prototype 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 9d ago.

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

Game Polished Prototype

Goal

Produce a polished prototype, not just a barely playable vertical slice.

Required quality bar

A valid polished prototype should usually include:

  • the requested core loop,
  • core requested features in scope,
  • a coherent menu / start / retry / pause flow when relevant,
  • readable HUD and affordances,
  • meaningful feedback and feel,
  • clear visual direction,
  • production-grade code structure for the critical path.

Use:

  • ./shared/checklists/polished-prototype-rubric.md
  • ./shared/checklists/production-code-checklist.md
  • ./shared/checklists/game-feel-pillars.md

Workflow

  1. Protect the user’s real ask. Do not cut away defining features merely to move faster.
  2. Build a strong first minutes experience.
  3. Implement the requested feature set for this pass, not just one isolated mechanic.
  4. Make the build feel deliberate: feedback, transitions, fail/retry, readability.
  5. Keep architecture clean enough to continue development.
  6. Verify and repair before calling it done.

Important

If the user asked for a strong prototype, first-playable is not enough. This skill exists to resist that accidental down-scoping.

Files

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
