architecture

A framework for choosing and recording software architecture decisions. It starts from requirements, weighs trade-offs, and can capture the reasoning in an ADR, or Architecture Decision Record.

In plain words
What is it for?
Use it when analysing system design, selecting patterns, or documenting choices about databases, APIs, and deployment architecture.
Why use it?
It provides a repeatable way to compare design options and preserve why a decision was 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

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 3d 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.

Origin

This is a copy

80% identical to architecture — 68 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Architecture Decision Framework(架构决策框架)

"Requirements drive architecture. Trade-offs inform decisions. ADRs capture rationale."(需求驱动架构,权衡决定结论,ADR 记录依据。)

Selective Reading Rule(选择性阅读规则)

Read ONLY files relevant to the request(仅阅读与请求相关的文档)! Check the content map, find what you need(查阅内容地图,找到所需信息)。

File(文件) Description(描述) When to Read(阅读时机)
context-discovery.md Questions to ask, project classification(提问列表、项目分类) Starting architecture design(开始架构设计)
trade-off-analysis.md ADR templates, trade-off framework(ADR 模板、权衡分析框架) Documenting decisions(记录决策)
pattern-selection.md Decision trees, anti-patterns(决策树、反模式) Choosing patterns(选择模式)
examples.md MVP, SaaS, Enterprise examples(示例) Reference implementations(参考实现)
patterns-reference.md Quick lookup for patterns(模式速查) Pattern comparison(模式对比)

Skill(技能) Use For(用途)
@[skills/database-design] Database schema design(数据库模式设计)
@[skills/api-patterns] API design patterns(API 设计模式)
@[skills/deployment-procedures] Deployment architecture(部署架构)

Core Principle(核心原则)

"Simplicity is the ultimate sophistication."(至简即至繁)

  • Start simple(从简单开始)。
  • Add complexity ONLY when proven necessary(仅在必要时增加复杂性)。
  • You can always add patterns later(随时可补充模式)。
  • Removing complexity is MUCH harder than adding it(移除复杂性远比增加难)。

Validation Checklist(验证检查清单)

Before finalizing architecture(最终确定架构之前):

  • Requirements clearly understood(需求已清晰理解)。
  • Constraints identified(约束条件已明确)。
  • Each decision has trade-off analysis(每项决策有权衡分析)。
  • Simpler alternatives considered(已考虑更简单替代方案)。
  • ADRs written for significant decisions(重大决策已编写 ADR)。
  • Team expertise matches chosen patterns(团队能力与模式匹配)。

Files

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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 MisonL/Ling (9 stars, last pushed 5mo ago), licensed MIT. It adds 59 tokens to every session and 643 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 80% identical to architecture, differing in 68 lines, and is treated as a copy.
