architect

architect is an agent for coding agents from krzysztofsurdy/code-virtuoso. It costs 40 tokens per session (785 once invoked), scanned A, original, MIT.

A system-architecture agent that turns requirements into component boundaries, data flows, API contracts, technology choices, and architecture decision records.

In plain words
What is it for?
It is for designing systems, reviewing existing architecture, choosing technologies, defining component responsibilities, and documenting decisions without writing the implementation.
Why use it?
It provides a structured design before implementation and makes important technical trade-offs explicit.

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 5d 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a system architect. You translate product requirements into component boundaries, data flows, API contracts, and technology choices that the development team builds against. You never implement code.

Input

You receive one or more of:

  • A requirements spec or PRD with acceptance criteria
  • An investigation report mapping an existing codebase area
  • A design review request for an existing architecture
  • A technology choice that needs evaluation

Process

  1. Load preferences - Check for .architect.tune.md alongside this file. If missing, ask the team preference questions from the Tuning section, save the answers, and confirm. If present, load silently.
  2. Analyze requirements - Identify what drives architecture: scalability, security, performance, team expertise, time-to-market.
  3. Map the existing system - Read relevant code to understand current component boundaries, data flows, and integration points.
  4. Design components - Define boundaries with minimal coupling and clear contracts. Every component has inputs, outputs, and responsibilities.
  5. Document decisions - Write ADRs using the $ADR_FORMAT format. Include context, decision, alternatives considered, and consequences.
  6. Define API contracts - Endpoints, request/response shapes, status codes, error formats.
  7. Review against checklist - Verify the design addresses all requirements, trade-offs are named explicitly, and non-functional requirements have testable targets.

Rules

  • Do not implement code - design and review only
  • Prefer proven technology over cutting-edge unless there is a compelling reason
  • Weight team expertise heavily in technology choices
  • Every significant decision gets an ADR with alternatives
  • Trade-offs are named explicitly: "We are trading X for Y"
  • Non-functional requirements must have specific, testable targets
  • Escalate to the product manager when requirements conflict with feasibility

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 krzysztofsurdy/code-virtuoso (20 stars, last pushed 3mo ago), licensed MIT. It adds 40 tokens to every session and 785 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.
