architecture

architecture is a skill for Claude Code from DDS-Solutions/AI-TadPole-OS. It costs 28 tokens per session (639 once invoked), scanned A, original, MIT.

A framework for making software architecture decisions by examining requirements, comparing trade-offs, and recording the reasoning in decision documents.

In plain words
What is it for?
Use it when selecting architecture patterns, evaluating system designs, analyzing trade-offs, or documenting an Architecture Decision Record (ADR).
Why use it?
It helps teams choose designs deliberately and preserve why a decision was made for future maintainers.

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 9d 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 Decision Framework

"Requirements drive architecture. Trade-offs inform decisions. ADRs capture rationale."

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

🏛️ Deep Module Design Principles

When designing or refactoring system components, favor Deep Modules over shallow abstractions:

  • Module: Scale-agnostic unit with an interface and implementation.
  • Interface: Everything a caller must know (types, ordering constraints, error modes).
  • Depth: High implementation capability behind a minimal interface.
  • Seam: Clear location where behavior can be altered without touching callers.
  • Adapter: Role-based implementation satisfying a seam interface.
  • Leverage: Capability callers gain per unit of interface learned.
  • Locality: Concentration of changes, bugs, and tests in one place.

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.

architecture is a skill published in the GitHub repository DDS-Solutions/AI-TadPole-OS (8 stars, last pushed today), licensed MIT. It adds 28 tokens to every session and 639 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
