architecture

architecture is a skill for Codex from automagik-dev/genie. It costs 47 tokens per session (1,435 once invoked), scanned A, original, MIT.

A framework for reviewing software architecture, including module boundaries, design contracts, abstraction depth, and error handling.

In plain words
What is it for?
Use it when assessing a codebase's structure, deciding whether an abstraction is justified, or reviewing how modules hide complexity and handle failures.
Why use it?
It helps identify unnecessary complexity and unclear dependencies before changing the code.

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 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.

How it starts

The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Architecture Review

Runtime syntax: invoke the plugin copy through the active runtime's owner-qualified skill selector; use a bare selector only when intentionally selecting a user-tier copy (a separately installed personal copy; Genie no longer seeds this tier). Cross-skill prose below uses bare names as portable semantic routes; the orchestrator resolves the selector for the active runtime.

Lens

This lane treats complexity as anything that makes a system hard to understand or modify — it accumulates as dependencies and obscurity. KISS comes first: begin with the simplest complete design that satisfies current user stories, and make every added mechanism earn its carrying cost with a present contractual need or measurement. Hypothetical future scale is not evidence. The unit of judgment is the module: deep modules (simple interface, substantial implementation) are good; shallow modules (interface as complicated as what they hide) are architecture debt. Information leakage, pass-through methods, temporal decomposition, and speculative optimization are the smells to hunt. Prize "define errors out of existence" and design-it-twice thinking.

This lane's lens is inspired by the work of John Ousterhout, author of A Philosophy of Software Design.

Mandate

Assess and report by default. Apply changes only when the invocation explicitly asks. Every finding must cite the concrete interface, import, or branch that embodies it — no vibes. Findings outside this lane (failing gates, security holes, missing tests) get a one-line handoff to the relevant lane skill under skills/. When you have enough information to judge, judge; recommend one design, not a survey.

Discover the Ground Truth First

Architecture is judged against the repo's own stated intent, then against first principles. Before scoring anything, collect: CLAUDE.md / AGENTS.md architecture sections, ADRs or design docs, any documented invariants ("X must never import Y", "state lives in Z"), and the real module graph traced from the entry points via imports. A repo's deliberate constraints (zero-daemon designs, intentionally-duplicated modules, forbidden cross-imports) are the design under review — the defect is a violated contract or a contract the code has outgrown, not the contract's existence.

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 automagik-dev/genie (334 stars, last pushed 2d ago), licensed MIT. It adds 47 tokens to every session and 1,435 once invoked, about $0.0002 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 2026-08-30.
