arch-review

arch-review is a command for Claude Code from 10Legs/freelance-developer-harness. It costs 8 tokens per session (259 once invoked), scanned A, original, MIT.

A command for reviewing a proposed software architecture with a solution architect’s approval gate. It checks design patterns, simplicity, security, scalability, and whether important decisions were recorded.

In plain words
What is it for?
It helps review architecture proposals, assess security and growth risks, check for duplicated designs, and record the decision in an architecture review document.
Why use it?
It catches structural problems before implementation begins. The approval states make clear whether work may proceed, needs conditions addressed, or requires a redesign.

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

arch-review 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.

Review Checklist

Solution Architect evaluates:

Pattern Compliance

  • Does this follow established patterns in patterns/architecture/?
  • If new pattern, has it been documented?
  • Are there reusable patterns being duplicated unnecessarily?

Design Principles

  • Is this the simplest design that meets requirements?
  • Is it designed for change (extensible)?
  • Are all decisions documented?

Security

  • Has Security Reviewer been consulted for security-sensitive decisions?
  • Are there any obvious security concerns?

Scalability

  • Does this design hold under 10x current expected load?
  • Are there single points of failure?

ADR Requirement

  • Have all significant decisions been recorded as ADRs?

Verdict

  • APPROVED — Implementation may proceed
  • APPROVED WITH CONDITIONS — Implementation may proceed after addressing listed conditions
  • BLOCKED — Fundamental redesign needed (specific issues listed)

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.
