architect

architect is a skill for Claude Code from mifunedev/openharness. It costs 187 tokens per session (1,538 once invoked), scanned A, original, Apache-2.0.

An architecture review that decides how a software system should be structured before an implementation plan is written. It bases its recommendations on the current repository.

In plain words
What is it for?
It helps produce an architecture brief for changes that affect how system parts interact or how data and work are owned.
Why use it?
It helps resolve major choices about module boundaries, execution, and ownership before coding makes them harder to change.

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

Architect

Determine what the system should become before /spec commits the implementation plan. This skill decides architecture; it does not implement.

Arguments received: $ARGUMENTS

Execution model

Run inline in the active coding-agent session. The session that invoked /architect keeps ownership of the work and of everything that follows it.

  • Do not fork the context, launch another coding-agent process, open a tmux or Herdr session, or hand the decision to a separate persistent identity.
  • Do not create an architect agent definition. The role is this skill; the runtime is the session already reading it.
  • Use /delegate only for bounded, self-contained fan-out — parallel independent source reads whose verbose output should stay out of this context. Reconcile every delegated result here; the brief is written by this session.

Roles are behavior, skills encode behavior, and agents execute behavior. A second agent context is justified only when isolation or parallelism is itself the thing being bought.

1. Classify

Architecture review is selective, not ceremony. Treat the change as ARCHITECTURAL when it materially affects one or more of:

  • system or module boundaries;
  • the execution or ownership model;
  • persistent state or the data model;
  • a security or isolation boundary;
  • a public API or compatibility contract;
  • a lifecycle or state machine;
  • provider portability;
  • shared conceptual vocabulary;
  • cross-skill or control-plane behavior;
  • a new reusable abstraction;
  • the replacement or retirement of an existing abstraction;
  • a structural decision that is difficult or expensive to reverse.

Otherwise the change is NOT-ARCHITECTURAL. Say so in two or three sentences, name the reason, route the work straight to /spec plan, and stop. Do not produce the full brief for a small local change.

2. Ground the decision

Before reasoning, read real sources. Synthesized recall is advisory; current source and accepted decision records are authority.

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 a skill published in the GitHub repository mifunedev/openharness (37 stars, last pushed yesterday), licensed Apache-2.0. It adds 187 tokens to every session and 1,538 once invoked, about $0.0009 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 2026-09-04.
