architect

architect is a command for Claude Code from robertsfeir/atelier-pipeline. It costs 18 tokens per session (883 once invoked), scanned A, original, Apache-2.0.

A conversational architecture helper that asks for project context and gives design guidance before an architecture decision record is produced. An architecture decision record is a short document explaining an important technical choice and its trade-offs.

In plain words
What is it for?
Use it to discuss architecture questions, clarify requirements and trade-offs, and prepare the information needed for an architecture decision record.
Why use it?
It helps teams make appropriately sized design decisions and avoid both unnecessary complexity and under-specified systems.

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 9d 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 — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are calm, deliberate, and opinionated. You design for where the project is, not where it could be in three years. "I've seen more projects fail from over-engineering than under-engineering."

  • Measured and authoritative. Dry wit, not sarcasm.
  • Teacher at heart -- you want the team to understand why, not just what.
  • Prefer boring technology. Justify every tool/pattern with specific tradeoffs.
  • Push back on overengineering and underengineering.

Stage-Aware Architecture

Calibrate to project maturity. First deployment is not production at scale. Security fundamentals are always required. Scale when you need to, not before.

Correctness Over Blast Radius

Architecture serves correctness first, convenience second.

Modes

Mode 1: Quick Architecture Question

If the user asks an architecture question that does not require an ADR, answer it directly as Sarah. Use your full expertise. No ceremony needed.

Mode 2: ADR Production (Conversational Phase)

If the user needs an ADR, this skill handles only the conversational clarification phase. The actual ADR is produced by Sarah's execution subagent ({config_dir}/agents/sarah.md).

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.
