create-architecture

create-architecture is a skill for Claude Code from bullish0x/GameStudio. It costs 68 tokens per session (4,244 once invoked), scanned A, a copy of create-architecture, MIT.

A guided workflow for writing the main technical architecture document for a game. It turns approved game design documents into a blueprint for systems, data flow, and programming boundaries.

In plain words
What is it for?
Use it to define a game's overall architecture, document how systems exchange data, and record the technical context needed for later implementation.
Why use it?
It gives developers a shared technical plan before sprint planning and coding begin. It also exposes missing engine information and incompatible design decisions early.

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

create-architecture 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 5d 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.

Origin

How it starts

The opening of the file, as written. The whole thing — 468 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create Architecture

This skill produces docs/architecture/architecture.md — the master architecture document that translates all approved GDDs into a concrete technical blueprint. It sits between design and implementation, and must exist before sprint planning begins.

Distinct from /architecture-decision: ADRs record individual point decisions. This skill creates the whole-system blueprint that gives ADRs their context.

Resolve the review mode (once, store for all gate spawns this run):

  1. If --review [full|lean|solo] was passed → use that
  2. Else read production/review-mode.txt → use that value
  3. Else → default to lean

See .agents/docs/director-gates.md for the full check pattern.

Argument modes:

  • No argument / full: Full guided walkthrough — all sections, start to finish
  • layers: Focus on the system layer diagram only
  • data-flow: Focus on data flow between modules only
  • api-boundaries: Focus on API boundary definitions only
  • adr-audit: Audit existing ADRs for engine compatibility gaps only

Phase 0: Load All Context

Before anything else, load the full project context in this order:

0a. Engine Context (Critical)

Read the engine reference library completely:

  1. docs/engine-reference/[engine]/VERSION.md → Extract: engine name, version, LLM cutoff, post-cutoff risk levels
  2. docs/engine-reference/[engine]/breaking-changes.md → Extract: all HIGH and MEDIUM risk changes
  3. docs/engine-reference/[engine]/deprecated-apis.md → Extract: APIs to avoid
  4. docs/engine-reference/[engine]/current-best-practices.md → Extract: post-cutoff best practices that differ from training data
  5. All files in docs/engine-reference/[engine]/modules/ → Extract: current API patterns per domain

If no engine is configured, stop and prompt:

"No engine is configured. Run /setup-engine first. Architecture cannot be written without knowing which engine and version you are targeting."

0b. Design Context + Technical Requirements Extraction

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.
