architecture

architecture is a skill for Claude Code, Codex from beel-collab/presets.dev. It costs 26 tokens per session (465 once invoked), scanned A, a copy of architecture, MIT.

An architecture decision framework for analyzing requirements, comparing design trade-offs, choosing patterns, and recording the reasoning in architecture decision records (ADRs).

In plain words
What is it for?
Use it when designing or reviewing a system, selecting architectural patterns, or documenting why a design decision was made.
Why use it?
It helps avoid adding unnecessary complexity and makes important system-design choices easier to explain and review later.

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

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 1mo 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.

Core Principle

"Simplicity is the ultimate sophistication."

  • Start simple
  • Add complexity ONLY when proven necessary
  • You can always add patterns later
  • Removing complexity is MUCH harder than adding it

Validation Checklist

Before finalizing architecture:

  • Requirements clearly understood
  • Constraints identified
  • Each decision has trade-off analysis
  • Simpler alternatives considered
  • ADRs written for significant decisions
  • Team expertise matches chosen patterns

When to Use

This skill is applicable to execute the workflow or actions described in the overview.

Limitations

  • Use this skill only when the task clearly matches the scope described above.
  • Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
  • Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

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.
