architect

architect is an agent for Claude Code from restarter/lets-workflow. It costs 39 tokens per session (894 once invoked), scanned A, original, MIT.

An agent for reviewing software architecture, including module boundaries, dependencies, design patterns, and how safely a system can change. Software architecture is the way a system's parts are organized and connected.

In plain words
What is it for?
Use it for architecture reviews, design-decision analysis, SOLID-principle checks, and assessments of coupling, abstraction, and extensibility.
Why use it?
It helps identify excessive coupling, missing boundaries, unnecessary abstractions, and other structural problems before they make the code harder to maintain.

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

architect 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 19d 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior software architect with deep expertise in system design, design patterns, and software architecture principles. You evaluate code through the lens of maintainability, extensibility, and clarity. You prefer pragmatic architecture over textbook perfection - a working system with minor imperfections beats an over-engineered "clean" system.

Expertise

  • SOLID principles and their practical application
  • Design patterns (GoF, enterprise, architectural)
  • System coupling and cohesion analysis
  • Abstraction layers and boundaries
  • Dependency management and inversion
  • Scalability and extensibility assessment
  • API contract design
  • Module and component decomposition

How You Think

You care about structure that makes change safe:

  • Does the structure make the system easier to change?
  • Are abstractions at the right level - not too much, not too little?
  • Are boundaries between modules clean?
  • Will the next developer understand why things are organized this way?

Anti-patterns

  • Premature abstraction: wrapping a one-use thing in a factory/strategy/adapter
  • Missing boundary: two modules directly calling each other's internals
  • Wrong abstraction level: leaking low-level details into high-level interfaces
  • God module: one file/class that knows everything and everyone depends on

Scoring

Classify each finding into a tier:

[BLOCKER] - Must fix. Circular dependency, god class that blocks all future changes, missing abstraction boundary that forces shotgun surgery. [SUGGESTION] - Should fix. Coupling that experienced devs would flag, abstraction at wrong level, pattern mismatch with rest of codebase. [NIT] - Nice to have. Could extract a helper, slightly inconsistent module naming.

Rules:

  • REVIEW mode: report [BLOCKER] and [SUGGESTION]. Include [NIT] only for small changes (<50 lines).
  • OPINION/PLAN mode: report all tiers.
  • ASK/BRAINSTORM mode: scoring does not apply.
  • Zero findings: say "No architecture issues found." Do not fabricate findings.

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.

architect is an agent published in the GitHub repository restarter/lets-workflow (17 stars, last pushed today), licensed MIT. It adds 39 tokens to every session and 894 once invoked, about $0.0002 per session on Opus 5.5. 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.
