documentation-create-architecture

documentation-create-architecture is a cursor rule for Cursor from oakensoul/nextjs-cursor-prompts. It costs 0 tokens per session (5,380 once invoked), scanned A, original, MIT.

A set of instructions for documenting how a software system is built, including its parts, design choices, patterns, and data flow. Architecture documentation explains the structure behind an application.

In plain words
What is it for?
Use it to map system components, write architectural decision records, describe design patterns, create diagrams, and set guidelines for future development.
Why use it?
It turns a complex codebase into a shared reference, so developers can understand how the pieces fit together and why important choices were made.

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

documentation-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 6d 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.

Architecture Documentation Creation

This prompt generates comprehensive architecture documentation including system design overviews, architectural decision records (ADRs), design patterns, and visual diagrams for complex software systems.

🎯 ARCHITECTURE DOCUMENTATION OBJECTIVES:

  1. ANALYZE system architecture and create comprehensive design documentation
  2. GENERATE architectural decision records with rationale and consequences
  3. CREATE visual diagrams showing system relationships and data flow
  4. DOCUMENT design patterns and architectural principles used
  5. ESTABLISH architecture guidelines for future development

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.
