create-architecture

create-architecture is a skill for Claude Code, Codex from cenconq25/claude-code-app-studio. It costs 69 tokens per session (2,751 once invoked), scanned A, original, MIT.

A tool for writing the main architecture document for an app: the technical blueprint that explains its structure and lists the major decisions still needed.

In plain words
What is it for?
Use it after product requirements are approved to define the app’s technical shape and identify required architecture decisions.
Why use it?
It gives architecture decisions a shared structure and helps reveal missing framework or design information before implementation.

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 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.

How it starts

The opening of the file, as written. The whole thing — 411 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create Architecture

Produces the project's master architecture document — the technical blueprint that ADRs slot into. Without this, ADRs are scattered points without a structure.

Output: docs/architecture/architecture.md

Purpose / When to Run

Run when:

  • All MVP PRDs are individually approved and /review-all-prds returned PASS
  • The team is ready to commit to top-level structure before writing ADRs

Distinct from /architecture-decision (single decision) — this skill creates the frame that decisions hang on, plus the list of which ADRs are required.

Inputs

  • All design/prd/*.md
  • design/systems-index.md
  • design/concept.md
  • Existing docs/architecture/ADR-*.md (if any — typically retrofit)
  • docs/framework-reference/<framework>/
  • .claude/docs/technical-preferences.md

Outputs

  • docs/architecture/architecture.md
  • A "Required ADRs" list inside that doc
  • Optional initial docs/architecture/architecture-registry.yaml skeleton

Phase 1: Pre-checks

  • Confirm framework is pinned (technical-preferences.md not [TO BE CONFIGURED])
  • Confirm at least 80% of MVP PRDs are APPROVED in design/systems-index.md
  • If /review-all-prds has not been run or returned PASS, warn: "Architecture without holistic PRD review can codify contradictions. Consider running /review-all-prds first." Allow proceed anyway.

If docs/architecture/architecture.md exists, ask:

  • Refresh sections (incremental) — re-author specific sections
  • Rebuild from scratch (back up first) — full new draft
  • Cancel

Phase 2: Read All Context

This skill is read-heavy. Hold in context:

  • All PRDs
  • Concept doc
  • Systems index
  • Existing ADRs (to integrate, not duplicate)
  • Framework reference: VERSION.md, conventions.md, breaking-changes.md
  • Technical preferences

Note knowledge-cutoff risk for the pinned framework — if HIGH, flag in the doc header that decisions in tricky domains must consult breaking-changes.md.

Phase 3: Skeleton

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.
