writing-game-plan

writing-game-plan is a skill for Claude Code from Simone-Tarantino/godot-superpowers. It costs 73 tokens per session (1,727 once invoked), scanned A, original, MIT.

A skill that turns an approved game design document, or GDD, into a milestone-based plan for building a Godot game. Godot is a game engine, and the plan connects work to specific reusable skills.

In plain words
What is it for?
Use it to plan a new game from its design document, create vertical slices, track milestones, and re-plan after a major scope change.
Why use it?
It gives a project a concrete order of work and shows where each planned feature fits before implementation begins.

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

writing-game-plan 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Writing a Game Plan

Convert an approved Game Design Document into an actionable, milestone-based implementation plan that uses the godot-superpowers skill catalog as its building blocks.

When to invoke

  • Immediately after game-brainstorming finishes (the standard handoff).
  • When picking up an existing project that already has a GDD but no plan.
  • When re-planning after a major scope change (write a NEW plan; do not edit the old one — keep the trail).

Inputs

  • The GDD (passed as argument, or located via docs/design/*-gdd.md). Read it fully before drafting.
  • Current project stategit status, ls, presence of project.godot, autoloads already registered, addons already installed. The plan must start from where the project actually is.

Plan structure

Save to docs/plans/<YYYY-MM-DD>-<slug>-plan.md. Required sections:

1. Header

# Implementation Plan — <Game Title>

- **GDD**: docs/design/<YYYY-MM-DD>-<slug>-gdd.md
- **Scope class**: jam / prototype / vertical slice / full game
- **Target platforms**: ...
- **Author**: <user> + Claude (godot-superpowers)
- **Date**: <YYYY-MM-DD>
- **Status**: Draft | Approved | In Progress | Done

2. Pillars + non-goals (copied verbatim from GDD)

So the plan can be read in isolation. If a milestone item conflicts with a pillar or hits a non-goal, the plan is wrong.

3. Milestones

Each milestone is a demo-able checkpoint — something the user could play / watch / show. Number them M0, M1, …

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.
