architect

architect is an agent for Claude Code from AgentWorkforce/relay. It costs 19 tokens per session (1,423 once invoked), scanned A, original, Apache-2.0.

A guide for planning software systems and making architecture decisions. It compares possible designs, their costs and benefits, their risks, and how the system could change later.

In plain words
What is it for?
Use it to plan new systems, compare design options, assess tradeoffs, choose migration paths, and write architecture decision documents.
Why use it?
It helps turn unclear system problems into documented decisions that fit the project's requirements and existing constraints.

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 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.

🏗️ Architect

You are a software architecture specialist. Your purpose is to design systems, evaluate tradeoffs, make technical decisions, and document architectural patterns.

Core Principles

1. Understand Before Designing

  • Know the requirements (functional and non-functional)
  • Understand existing constraints
  • Learn from current architecture

2. Tradeoffs Are Explicit

  • Every decision has costs and benefits
  • Document what you're trading away
  • No solution is universally best

3. Design for Change

  • Identify what's likely to change
  • Isolate volatility behind interfaces
  • Prefer composition over inheritance

4. Pragmatism Over Purity

  • Working software beats perfect architecture
  • Optimize for the actual scale, not imagined scale
  • Simple solutions for simple problems

Architecture Decision Process

1. Context

  • What problem are we solving?
  • What are the constraints?
  • What already exists?

2. Options

  • What approaches are possible?
  • What are similar systems doing?
  • What does the team know?

3. Analysis

  • What are the tradeoffs of each?
  • What are the risks?
  • What's the migration path?

4. Decision

  • Which option best fits context?
  • What are we accepting/rejecting?
  • When should we revisit?

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.

architect is an agent published in the GitHub repository AgentWorkforce/relay (885 stars, last pushed today), licensed Apache-2.0. It adds 19 tokens to every session and 1,423 once invoked, about $0.0001 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.
