documentation-update-architecture

documentation-update-architecture is a cursor rule for Cursor from oakensoul/nextjs-cursor-prompts. It costs 0 tokens per session (2,374 once invoked), scanned A, original, MIT.

A guide for updating architecture documentation, which describes how a software system is structured and how its major parts fit together. It keeps system descriptions, design decisions, diagrams, and technology details aligned with the implementation.

In plain words
What is it for?
Use it to inspect project structure, update architecture and design records, refresh diagrams, verify technologies, and check consistency across technical documents.
Why use it?
It prevents architecture documents from describing an older system or conflicting with the code and recorded design decisions.

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-update-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 7d 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 Update Guide

This prompt systematically updates architecture documentation to reflect current system design, architectural decisions, and technical evolution while maintaining comprehensive technical documentation standards.

🎯 OBJECTIVES:

  1. UPDATE system architecture to reflect current design and implementation
  2. MAINTAIN architectural decision records with current context and rationale
  3. SYNCHRONIZE technical diagrams with actual system implementation
  4. ENSURE design consistency across architecture documentation
  5. VALIDATE architectural alignment with current development practices

📋 ARCHITECTURE UPDATE PROCESS:

STEP 1: Current Architecture Assessment

System State Analysis:
echo "🏗️ Current Architecture Assessment"
echo "================================"

# Analyze current system structure
echo "Project Structure Analysis:"
find src/ -type d -maxdepth 3 | sort

# Check architecture-related files
echo "Architecture Documentation:"
find docs/ -name "*architecture*" -o -name "*design*" -o -name "*adr*"

# Verify technology stack
echo "Current Technology Stack:"
grep -E "(dependencies|devDependencies)" package.json -A 20

# Check for architectural patterns
echo "Architectural Patterns in Use:"
find src/ -name "*.ts" -o -name "*.tsx" | head -10 | xargs grep -l "interface\|class\|type"
Architecture Change Detection:
  • New system components added since last documentation update
  • Technology stack changes affecting architectural decisions
  • Design patterns that have evolved or been introduced
  • Integration points that have been added or modified
  • Performance considerations that have changed system design
Documentation Gap Analysis:
  • Missing architectural decisions not yet documented
  • Outdated diagrams not reflecting current system design
  • Incomplete component descriptions missing current functionality
  • Broken architectural patterns no longer accurately described
  • Integration documentation not reflecting current connections

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.
