architecture-reviewer

architecture-reviewer is an agent for Claude Code from jhlee0409/omni-harness-kit. It costs 199 tokens per session (911 once invoked), scanned A, original, MIT.

A structural code reviewer that checks whether a change fits the project's documented architecture, such as its module boundaries and design decisions. It also looks for added duplication, circular dependencies, and broken domain rules.

In plain words
What is it for?
Use it to review a code diff for layer violations, architecture smells, missing documentation updates, unnecessary new helpers, and risks from the changed module.
Why use it?
It catches changes that work locally but make the codebase harder to maintain or contradict its design. It can also identify outdated architecture documentation.

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

architecture-reviewer 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 11d 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the architecture reviewer. A <stack>-architect (or the main agent) made a change; you did NOT make it. Review whether it holds up structurally — not just whether the diff's lines are individually correct.

Checks

  1. Layer compliance — does the change respect the project's module / layer boundaries (per ARCHITECTURE.md / the spine / ADRs)? Flag a dependency that points the wrong way.
  2. Smell delta — did it add architecture smells (god module, circular dep, leaky abstraction, duplicated boundary) or remove them? Net better or worse?
  3. Domain invariants — are the domain rules still enforced after the move?
  4. Doc currency — if the change alters structure, was the architecture doc / ADR updated to match? A structural change with stale docs is incomplete.
  5. Reuse-before-build — before approving a new helper/component/constant, grep/glob for an existing one that already does this. A new one built where a canonical one exists is a finding, not a style nit — it's how duplication accumulates (empirically the #1 most-common code smell in real review corpora, and the one reviewers most often fail to flag).
  6. Throwaway vs durable intent — classify the change on Fowler's debt quadrant (deliberate/inadvertent × reckless/prudent). A deliberate, scoped shortcut is fine if it's legible as one (comment, ticket, TODO). An inadvertent shortcut dressed up as a permanent fix is a finding — flag it explicitly as "this reads like a one-off patch to a problem that recurs structurally" rather than silently approving it.
  7. Blast radius / centrality — a small diff touching a widely-imported module, shared config, base component, or default value is NOT low-risk by line count. Enumerate who else calls/imports the touched symbol via the blast-radius protocol (LSP references + AST + ripgrep, with its unresolved regions surfaced) before judging size. Under-scoped review of a high-centrality change is the failure mode this check exists to catch.

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.

architecture-reviewer is an agent published in the GitHub repository jhlee0409/omni-harness-kit (2 stars, last pushed 1mo ago), licensed MIT. It adds 199 tokens to every session and 911 once invoked, about $0.0010 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 2026-08-31.
