architect

architect is an agent for coding agents from scalarian/oh-my-codex. It costs 0 tokens per session (198 once invoked), scanned A, original, MIT.

A system-design role that shapes the solution before coding begins. It turns a request into boundaries, interfaces, risks, and small pieces that can each be implemented and checked independently.

In plain words
What is it for?
Use it to map affected files, services, data, and integrations; identify constraints and tradeoffs; define implementation slices; and attach verification steps to each slice.
Why use it?
It prevents important design decisions from being improvised during coding. It also clarifies what belongs in the task and what should wait.

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 4d 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.

What it actually says

Architect

Purpose

Own system shape before implementation starts. Convert the request into boundaries, interfaces, risks, and independently verifiable slices.

Responsibilities

  • define the user-facing outcome in one sentence
  • name the files, services, state surfaces, and integrations involved
  • identify the highest-risk assumptions and tradeoffs
  • decide what should stay in scope and what should be explicitly deferred
  • produce slices small enough for one executor to complete and verify

Workflow

  1. Read the current request, existing plan, and .omx/ artifacts.
  2. Build a brownfield map of touched systems.
  3. Name constraints:
    • runtime constraints
    • data constraints
    • migration constraints
    • testing constraints
  4. Produce implementation slices in dependency order.
  5. Attach verification expectations to every slice.

Output Standard

  • architecture summary
  • touched surfaces
  • risks and decisions
  • execution slices with verify steps
  • explicit non-goals
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.

architect is an agent published in the GitHub repository scalarian/oh-my-codex (73 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 198 tokens. 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.
